Configuration Guide for Cisco NCS 1014, IOS XR Release 24.3.x

AINS

The Automatic-In-Service (AINS) feature allows the controller to automatically move to the automatic-in-service state after the maintenance window is completed. A soak time period is associated with the AINS state. The controller automatically moves to the In-Service state after the soak time period is completed. During the AINS maintenance window, alarms are not propagated to the EMS/NMS monitoring system.

You can configure AINS on the client ports of the QXP, 1.2T, 2.4T, and 2.4TX cards.

AINS States

The following table lists the AINS states.


State	Description
None	AINS is not enabled on the controller or the soak time period is complete.
Pending	AINS is configured on the controller. However, the soak time period has not started because either the primary state of controller is in Shutdown, Admin down, or Not ready state or the secondary state is in Maintenance state. AINS can also move to Pending state if alarms are raised during the soak time period.
Running	AINS is enabled on the controller. The primary state of the controller is Up and the secondary state is AINS.

If there are any service-affecting alarms when AINS is running on ethernet or optics controllers, the AINS state moves to Pending state. When the alarms are cleared, the AINS state moves to Running state.

The AINS soak time period restarts when there are line card reloads, XR reloads, line card warm reloads, power cycles, or alarm conditioning.

Soak Time Period

You can configure the soak time period to be between 1 minute to 48 hours.

All alarms are suppressed during the AINS state. When the optical and ethernet alarms are raised on the port during the soak time period, the AINS state moves to Pending. These alarms are not displayed in the output of the show alarms brief card location 0/RP0/CPU0 active command but in the output of the show alarms brief card location 0/RP0/CPU0 conditions command. When all the alarms clear, the soak time period starts, and the AINS state moves to Running. When the soak time period expires, the port moves to IS state.

Configuring AINS

To configure AINS on a controller, use the following command:

automatic-in-service controller controller rate controller hours hours minutes minutes

The following is a sample to configure AINS on a controller.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios#automatic-in-service controller coherentDSP 0/0/0/12 hours 0 minutes 15
RP/0/RP0/CPU0:ios(config)#commit

To configure AINS on a muxponder slice, use the following command:

configure

hw-module location location mxponder-slice slice-number client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which slice 0 client ports are configured with AINS with soak time period specified to be 40 minutes.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3/nxr0 mxponder-slice 0 client-port-ains-soak hours 0 minutes 40
RP/0/RP0/CPU0:ios(config)#commit

To configure AINS globally, use the following command:

ains-soak hours hours minutes minutes

The following is a sample to configure AINS globally.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#ains-soak hours 0 minutes 15
RP/0/RP0/CPU0:ios(config)#commit

Disabling AINS

To disable AINS on all muxponder client ports, set the hours and minutes to 0. Use the following commands:

configure

hw-module location location mxponder-slice slice-number client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which AINS is disabled on all client ports.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3/nxr0 mxponder-slice 0 client-port-ains-soak hours 0 minutes 0
RP/0/RP0/CPU0:ios(config)#commit

To disable AINS on a muxponder slice, set the hours and minutes to 0. Use the following command:

configure

hw-module location location mxponder-slice slice-number client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which AINS is disabled on all client ports of slice 0.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3/nxr0 mxponder-slice 0 client-port-ains-soak hours 0 minutes 0
RP/0/RP0/CPU0:ios(config)#commit

Displaying the AINS Configuration

The AINS Soak field in the output indicates the current state of AINS. The current state can be None, Pending, or Running. The Total Duration field indicates the total soak time period that is configured. The Remaining Duration field indicates the soak time that remains, after which, the AINS state moves to None.

This example displays the ethernet controller statistics with AINS Soak in running state.

FEC

Forward Error Correction (FEC) is used for controlling errors during data transmission. This feature can be enabled on 1.2T and 2.4T cards and works by adding data redundancy to the transmitted message using an algorithm. This redundancy allows the receiver to detect and correct a limited number of errors occurring anywhere in the message, instead of having to ask the transmitter to resend the message.

FEC is automatically enabled on the pluggables installed in the Cisco NCS 1014. When you upgrade the software of an NCS 1014 with pluggables in the FEC disabled mode, traffic is affected.

The following sample shows the running FEC configuration on a 2.4T card:

FEC States for CoherentDSP Controller

The following table lists the FEC states for the coherentDSP controllers.

Q-Margin Support

Q-margin is an important optical parameter that characterizes the health of an optical link. The Q-margin value is calculated based on the average bit error rate (BER) in the optical link.

Enhanced Q-Margin Support

Enhanced Q-Margin is supported for Forward Error Correction (FEC) and Performance Monitoring on CoherentDSP controllers for 2.4T cards. Enhanced Q-margin provides a better error free signal in the optical link. The enhanced Q-margin value is calculated based on the maximum number of errors per frame. An attribute that is called instantaneous Q-margin is displayed in the output of the show controllers coherentDSP command. The lower the delta value between the instantaneous Q-margin value with the Q-margin value, the better the FEC performance of the NCS 1014 system. The instantaneous Q-margin values thus help you to optimize the system with continuous error correction in subsea transport networks.

Laser Squelching

You can enable laser squelching on Ethernet controllers. Laser squelching can be enabled on QXP, 1.2T, 2.4T, and 2.4TX cards which shuts down the laser in the event of trunk faults (LOS, LOF), and a SQUELCHED alarm is raised on the mapped client port.

Laser squelching uses an interrupt based method. Hence squelching happens faster when compared to previous releases. Squelch happens for client alarms also like Ingress LF, LOA, and CSF (not for egress client alarms) in addition to trunk fault cases.

To configure laser squelching on 1.2T card, use the following commands:

configure

controller HundredGigECtrlr Rack/Slot/Instance/Port

laser-squelch

commit

To configure laser squelching on a 2.4T and 2.4TX cards, use the following commands:

configure

controller HundredGigECtrlr Rack/Slot/Instance/Port/Lane | controller fourHundredGigECtrlr Rack/Slot/Instance/Port

laser-squelch

commit

Note

In case of muxponder configuration on the 2.4TX card, and if laser squelch is configured on the split port, whenever a fault is received on any one trunk, the corresponding split port will be squelched.

The following is a sample where laser squelching is enabled on the Ethernet controller of a 2.4T card and a 2.4TX card.

Protection Switching Use Cases

Fast-Squelching provides increased protection switching speed when there is a trunk fault or a client fault. Fast-Squelching is supported on 1.2T cards.

Note

Protection Switching is not supported on 2.4T card.

The following sample topology includes a Far End (FE) station and a Near End (NE) station. Each station includes an NCS 1014 node having two line cards. The nodes are connected to the respective Traffic generators through a Protection Switching Module (PSM).

Figure 1. Reference Topology for Protection Switching

Protection Switching Principle (Trunk fault)

If there is a fiber cut in the trunk working path from the FE station to the NE station, an LOS alarm is raised on the NE working trunk. This results in the squelching of all client ports mapped to the working NE trunk port. As the laser of the client port is squelched, LOS is reported on the W-RX2 port of the PSM2. As the received optical power on the W-RX2 port of PSM is below the threshold, PSM2 switches to receive the optical signal in the P-RX2 port instead of the W-RX2 port. Hence switching happens for traffic from work to protect in FE station to NE station direction.

In the case of a unidirectional trunk fault, switching happens in one direction as explained above. In the other direction, when LOS is received at the W-RX2 port of PSM2, W-TX2 sends LOS for 25 milliseconds. When LOS is reported on the NE client port, fault gets propagated over the trunk, resulting in the squelching of FE station client ports. Finally, the LOS on the PSM port results in switching in this direction as well. In this way, bidirectional switching is implemented.

Protection Switching Principle (Client fault)

When a client failure happens on the FE station, a Client Signal Failure (CSF) alarm is raised on the NE station trunk. The CSF on the trunk results in the squelching of the corresponding client port, and the PSM switching happens. In summary, a fault on the NE station client RX port results in CSF on the FE station trunk, and the switching happens. And, a fault on the NE station client TX port results in LOS on the PSM ports, and the switching happens.

Note

PSM must be in the standalone mode.
PSM alarm threshold must be set to +/ –3 dBm from the actual power received in the PSM RX port.
If line card protection is required, the working and protect path must be configured in two different line cards.
If only client protection is required, the working and protection path can be configured in the same line card.
If the LC trunk configuration is x50 rate, then we can’t use single line card for work and protection due to x50 coupled mode limitations (coupled trunk).
Manual switch, Force switch, and lock-out protection on PSM, result in bidirectional switching.

Idle Insertion

When a fault occurs on the trunk port, you can hold the propagation of local faults using the idle insertion feature. This feature is can be enabled on the ethernet controllers of 1.2T, 2.4T, and 2.4TX cards by configuring the hold-off timer.

When the fault occurs on the trunk, idles are inserted in the traffic stream from the trunk port to the client port for the duration of the configured holdoff-time. If the trunk port remains faulty beyond the configured holdoff-time, a local fault is transmitted towards the client device. If the trunk recovers from the fault before the holdoff-time expires, traffic resumes.

This feature can be used on customer deployments to prevent reset of client ports during a PSM switchover.

Configure Idle Insertion

You can enable the idle insertion feature on a 1.2T card using the following commands:

configure

controller HundredGigECtrlr Rack/Slot/Instance/Port

holdoff-time trunk-fault time-value

You can enable the idle insertion feature on 2.4T card and 2.4TX card using the following commands:

configure

controller HundredGigECtrlr Rack/Slot/Instance/Port/Lane | controller fourHundredGigECtrlr Rack/Slot/Instance/Port

holdoff-time trunk-fault time-value

The range of timevalue is from 0 ms to 3000 ms.

Note

In case of muxponder configuration on the 2.4TX card, holdoff timer is not supported on the split ports.

Example 1

The following is a sample for enabling the hold off -timer in 100GE controller:

Idle Insertion for Ethernet Controllers

Idle insertion for Ethernet controllers feature allows you to perform end-to-end link verification between 100GE or 400GE Ethernet controllers before bringing up the actual traffic. This feature enables you to perform pre-provisioning checks to isolate link errors in advance without any Ethernet testers.

Note

OTU4 client rate is not supported.

Idle frames can be inserted in both the ingress and egress directions on Ethernet controllers and the LOCAL-FAULT and REMOTE-FAULT alarms are cleared. The performance monitoring counters on the pcs layer are monitored to check for any errors on the link.

Warning

Do not configure the Idle insertion for Ethernet controllers feature on the link that carries live traffic.

Configuring Idle Insertion for Ethernet Controllers

Before You Begin:

Do not configure idle frame insertion with hold-off timer.

You can configure this feature by using the following commands:

configure

controller hundredGigECtrlr Rack/Slot/Instance/Port/

insert-idle ingress

insert-idle egress

commit

end

The following is a sample for enabling the idle ingress and idle egress in 100GE controllers:


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#controller hundredGigECtrlr 0/2/0/2
RP/0/RP0/CPU0:ios(config-eth-ctrlr)#insert-idle ingress
RP/0/RP0/CPU0:ios(config-eth-ctrlr)#insert-idle egress
RP/0/RP0/CPU0:ios(config-eth-ctrlr)#commit
RP/0/RP0/CPU0:ios(config-eth-ctrlr)#end

You can disable this feature by using the following commands:

configure

controller hundredGigECtrlr Rack/Slot/Instance/Port

no insert-idle ingress

no insert-idle egress

commit

end

Limitation

After disabling the idle frame insertion feature, the LOCAL-FAULT or REMOTE-FAULT alarm may not appear again because the idle frames are in loop. Hence, you must break the idle frame loop in the link by performing either one of the following:

Perform fiber OIR on either the near-end or far-end client port.
Perform shut and unshut operation on any client port.

FlexO GID and IID

The 2.4T and 2.4TX cards use flexible OTN (flexO) interfaces on trunk ports. These flexO interfaces provide a flexible and interoperable mechanism to transport OTU signals by grouping standard lower rate interfaces. Each flexO interface group is identified by a flexO group identification (GID) number, which ranges 1–1,048,576. Each member of a flexO group is identified by a flexO instance identification (IID) number. The IID cannot be changed.

Configuring FlexO GID

To configure flexO GID and IID on the coherentDSP controller, enter the following commands:

configure

controller coherentDSP R/S/I/P

Link Layer Discovery Protocol (LLDP) Support on Management Interface

The LLDP can be configured on management interface of 1.2T, 2.4T, and 2.4TX cards. It requires a system to form LLDP neighborship over the system management interface, through which it advertises and learns LLDP neighbor information. This information about neighbors is used to learn about the neighbors and in turn the topology of the devices for Operations, Administration, and Maintenance (OAM) purposes.

Advantages of LLDP

Provides support on non-Cisco devices.
Enables neighbor discovery between non-Cisco devices.

Limitation

When you disable LLDP globally, the LLDP gets disabled on all the interfaces.

Note

By default, LLDP is enabled for NCS 1014. But when you enable and disable LLDP in the global configuration mode, LLDP gets disabled on all the interfaces.

Workaround: You must enable LLDP globally or reload the Router.

Cisco Discovery Protocol (CDP) vs LLDP

The CDP is a device discovery protocol that runs over Layer 2. Layer 2 is also known as the data link layer that runs on all Cisco devices, such as routers, bridges, access servers, and switches. This protocol allows the network management applications to automatically discover and learn about other Cisco devices that connect to the network.

The LLDP is also a device discovery protocol that runs over Layer 2. This protocol allows the network management applications to automatically discover and learn about other non-Cisco devices that connect to the network.

Interoperability between non-Cisco devices using LLDP

LLDP is also a neighbor discovery protocol that is used by network devices to advertise information about themselves to other devices on the network. This protocol runs over the data link layer, which allows two systems running different network layer protocols to learn about each other.

With LLDP, the user can also access the information about a particular physical network connection. If the user uses a non-Cisco monitoring tool (through SNMP), LLDP helps you identify the Object Identifiers (OIDs) that the system supports. The following OIDs are supported:

1.0.8802.1.1.2.1.4.1.1.4
1.0.8802.1.1.2.1.4.1.1.5
1.0.8802.1.1.2.1.4.1.1.6
1.0.8802.1.1.2.1.4.1.1.7
1.0.8802.1.1.2.1.4.1.1.8
1.0.8802.1.1.2.1.4.1.1.9
1.0.8802.1.1.2.1.4.1.1.10
1.0.8802.1.1.2.1.4.1.1.11
1.0.8802.1.1.2.1.4.1.1.12

Neighbor Discovery

System advertises the LLDP TLV (Type Length Value) details over the management network using which other devices in the management network can learn about this device.

Configuring LLDP

LLDP full stack functionality is supported on all three management interfaces supported in NCS 1014.
You can selectively enable or disable LLDP on any of the management interfaces on demand.
You can selectively enable or disable LLDP transmit or receive functionality at the management interface level.
Information gathered using LLDP can be stored in the device Management Information Database (MIB) and queried with the Simple Network Management protocol (SNMP).
LLDP operational data are available in both Command Line Interface and netconf-yang interface.

Enabling LLDP Globally

When you enable LLDP globally, all interfaces that support LLDP are automatically enabled for both transmit and receive operations.

Note

You can override this default operation at the interface to disable receive or transmit operations.

The following table describes the global LLDP attributes that the user can configure:

Table 2.
Attribute	Default	Range	Description
Holdtime	120	0–65535	Specifies the hold time (in sec). Hold time refers to the time or duration that an LLDP device maintains the neighbor information before discarding.
Reinit	2	2–5	Delay (in sec) for LLDP initialization on any interface
Timer	30	5-65534	Specifies the rate at which LLDP packets are sent (in sec)

The following example shows the commands to configure LLDP globally. The global LLDP configuration enables LLDP on all the three management interfaces.

RP/0/RP0/CPU0:regen#configure terminal
RP/0/RP0/CPU0:regen(config)#lldp management enable 
RP/0/RP0/CPU0:regen(config)#lldp holdtime 30 
RP/0/RP0/CPU0:regen(config)#lldp reinit 2 
RP/0/RP0/CPU0:regen(config)#commit

Verification

You can verify the LLDP configuration using the show running-config lldp command.

The output of show running-config lldp command is as follows:

RP/0/RP0/CPU0:regen#show running-config lldp
Tue Dec 10 10:36:11.567 UTC
lldp

MAC Address Snooping on Client Ports

MAC address snooping allows you to learn the MAC address of the neighbor on 1.2T cards, that is connected to the client ports. You can enable ARP snooping on all client ports and learn the MAC address of neighbors through CLI.

This feature overcomes the limitation, where LLDP (Link Layer Discovery protocol) cannot be enabled in some networks.

Limitations

When you enable or disable MAC address snooping on any slice, few packets are dropped during configuration.
Open config interface for enabling or disabling MAC address snooping is not supported.
SNMP MIB is not supported for the MAC address attribute.

Note

When you enable MAC address snooping on client ports, it overrides LLDP.

Configuring MAC Address Snooping on Client Ports

You can configure MAC address or ARP snoop on slice in Muxponder slice mode using the following commands.

configure

hw-module location location mxponder-slice slice-number

client-rate 100GE

trunk-rate 600G { 100G | 150G | 200G | 250G | 300G | 350G | 400G | 450G | 500G | 550G | 600G }

Loopback

You can configure loopback on the CoherentDSP and Ethernet controllers of QXP, 1.2T, 24TX and 2.4T cards to identify connection problems. The loopback can be configured only in the maintenance mode. Use the controller controller-type and the secondary-admin-state maintenance commands to place the controllers in the maintenance mode.

Loopback configuration alarm details for each controller are triggered whenever there is a change in the loopback configuration. Details such as, location of the controller, severity, configuration date and time, and description are available in the output of the show alarms brief system active and show alarms brief history commands.

Configuring Loopback on the 1.2T Card

To configure the loopback on a 1.2T card, use the following commands:

controller controllertype Rack/Slot/Instance/Port

sec-admin-state maintenance

loopback [ internal ]

Note

Line loopback is not supported on CoherentDSP controller of 1.2T card.

Configuring Loopback on 2.4T Card and 2.4TX Card

To configure the loopback on 2.4T card and 2.4TX card, use the following commands:

controller {HundredGigECtrlr Rack/Slot/Instance/Port/Lane | fourHundredGigECtrlrRack/Slot/Instance/Port}

sec-admin-state maintenance

loopback [ line | internal ]

Note

In case of muxponder configuration on the 2.4TX card, internal loopback must be applied on both trunk ports for the loopback behaviour to reflect on the split ports. For direct ports, the corresponding trunk internal loopback works as expected.

Example 1

The following example shows how a internal loopback is configured on the Ethernet controller of a 1.2T card.

Restore Factory Settings

Note

Perform this operation only on the console port.

You can restore the factory settings on the NCS 1014. The entire system configuration, including usernames, passwords, and IP addresses, is removed. You can perform this operation only through the console port and not on the management interface. To restore NCS 1014 to factory settings, use the commit replace command. After the commit replace operation completes, you must perform the IOS XR reload operation.

The commit best-effort command merges the target configuration with the running configuration and commits only valid changes (best effort). Some configuration changes might fail due to semantic errors.

Headless Mode

During process restarts, CPU reload, or removal of CPU, the NCS 1014 operates in headless mode for up to 72 hours. During this time, traffic is not impacted, although the control plane is not up and running. Fault propagation continues to operate for failures on client and trunk ports. However, you cannot provision anything nor view operational data with a non-functional CPU. Performance monitoring data based on 15 minutes and 24 hour intervals is not supported with a non-functional CPU.

Trail Trace Identifier

The Trail trace identifier (TTI) feature helps you to identify the signal from the source to the destination within the network. You can configure the TTI sent or expected in ASCII and HEX. When the expected TTI string does not match the received TTI trace string, the controller goes down and the TIM alarm is raised. To configure TTI on the coherent DSP controllers of a 1.2T, 2.4T, or 2.4TX card, use the following commands:

configure

controller coherentDSP R/S/I/P tti {sent | expected} ascii | hextti-string

commit

Note

The tti-string can have a maximum of 64 characters for ASCII and 128 characters for HEX.

The following sample displays how to configure TTI on a coherent DSP controller with the sent and expected strings set to the same ASCII string. The state of the controller is up.

Configure TTI on QXP Card

You can configure the TTI sent or expected string in the full ASCII format, or Source Access Point Identifier (SAPI)/Destination Access Point Identifier (DAPI) format on ODU-flex, ODU4, and coherentDSP controllers for the QXP card.

Note

TTI operates only in trunk mode OR .

The following table lists the ASCII format that is supported for TTI:


ASCII with Character String	Controller
Full ASCII 64-character	CoherentDSP,odu4,odu-flex
SAPI ASCII 15-character	CoherentDSP,odu4,odu-flex
DAPI ASCII 15-character	CoherentDSP,odu4,odu-flex
Operator-specific ASCII 32-character	CoherentDSP,odu4,odu-flex

To configure TTI, use the following commands:

configure

controller controller-type R/S/I/P tti {sent | expected} {ascii | sapi ascii | dapi ascii | operator-specific ascii } tti-string

Chromatic Dispersion

You can configure chromatic dispersion on optics controllers of 1.2T, 2.4TX, and 2.4T cards. When you configure the maximum and minimum values for chromatic dispersion for any data rate, ensure the minimum difference between the configured values is equal to or greater than 1500 ps/nm.

The following table lists the default CD search range for a 1.2T card.


Data Rate	BPS	Card Support	Default CD Search Range
200G to 500G	BPS < = 3	1.2T, 1.2TL	-10,000 to 100,000 ps/nm
	3 < BPS <= 4	1.2T, 1.2TL	-10,000 to 80,000 ps/nm

Note

The cd-min and cd-max values must be set for BPS values that are greater than 4 in the 1.2T card.

Note

When the user provisions the cd-min and cd-max values that are outside the range through CLI, the provisioned values are accepted; however, only the actual values supported by the hardware are applied.

The following is a sample where chromatic dispersion is configured on the optics controller.

Optical Signal to Noise Ratio

You can configure the minimum acceptable Optical Signal to Noise ratio (OSNR) value on the 1.2T, 2.4TX, and 2.4T cards. The OSNR alarm is raised if OSNR goes below this value.

The range is 0–4000 (in units of 0.01db).

To configure the minimum acceptable OSNR, use the following command:

configure

controller optics R/S/I/P

CCMD-16 Controllers

The NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards have two types of controllers. The controllers are OMS and OCH controllers. When the NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards become operational, both the OMS and OCH controllers are automatically created by default.

To view the OCH controllers, run the following command:

Command

RP/0/RP0/CPU0:ios#show controllers och ?

The following output shows the active OCH controllers in Slot 0 from port 1 to 16.

Output Example

Table 5. Feature History
Feature Name	Release Information	Feature Description
Supported Functionalities of CCMD-16-C and CCMD-16-L Line Cards	Cisco IOS XR Release 7.11.1	Supported Functionalities of CCMD-16-C and CCMD-16-L Line Cards: The software supports Variable Optical Attenuator (VoA), power monitoring and reporting of parameters to the controllers at the OCH and OMS level. It helps in configuring the amplifier parameters for optimizing signal transmissions. The software also supports in-band and out-of-band tone detection and monitoring and reporting of alarms.

This chapter describes the controller configuration using EDFA, VoA, optical safety, and photodiode parameters which are supported on NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L line cards.

Table 6. Basic Controller Configuration Parameters
Parameter	CLI	Description
EDFA-ADD Control Mode	`controller Oms R/S/I/P` `egress-ampli-mode power-control`	Here the default mode is gain-control. Use this command to change the mode to power-control mode. You can delete this configuration to revert to gain-control mode.
EDFA-ADD Power	`controller Oms R/S/I/P` `egress-ampli-power <val in 0.1 dBm>`	This is the target output power configuration for the EDFA located on COM-Tx. If the output power is not configured, then a default value is used by the system. You can find the applied target output power by using the show controller oms output.
EDFA-ADD Gain Range	`controller Oms R/S/I/P` `egress-ampli-gain-range <normal \| extended>`	If you change the gain range from Normal to Extended or the opposite way, without updating the proper gain value for the new gain range, then the following may happen: The EDFA switches to the preconfigured or default value of the gain causing a mismatch between the operational and configured gain. The gain configuration is lost during the reload of software or line card, as the configured gain mismatches with the latest gain-range. This may result in traffic interruption during these reload operations. Hence, we recommend that you explicitly configure the gain range mode as normal or extended, and the corresponding gain values for each mode to get the expected results. The following are a few example scenarios that may not work as expected: Scenario 1: Current running config: `controller Oms R/S/I/P egress-ampli-gain-range extended egress-ampli-gain <gain value in extended mode>` New applied config: `controller Oms R/S/I/P no egress-ampli-gain-range extended commit` Scenario 2: Current running config: `controller Oms R/S/I/P egress-ampli-gain-range extended egress-ampli-gain <gain value in extended mode>` New applied config: `controller Oms R/S/I/P egress-ampli-gain-range Normal commit` Scenario 3: Current running config: `controller Oms R/S/I/P egress-ampli-gain <gain value in normal mode>` New applied config: `controller Oms R/S/I/P egress-ampli-gain-range extended commit` The following is another example scenario that involves commit-replace command where you replace the existing gain configuration that does not have explicitly configured gain-range, with new gain-range and gain value. Scenario 4: Current running config: `controller Oms R/S/I/P egress-ampli-gain <gain value in normal mode>` New applied config: `………….. controller Oms R/S/I/P egress-ampli-gain-range extended egress-ampli-gain <gain value in extended mode> commit replace`
EDFA-ADD Gain	`controller Oms R/S/I/P` `egress-ampli-gain <val in 0.1 dB>`	This is used for configuring gain for the EDFA located on the COM-Tx port. If the gain is not configured, then a default value is used by the system. The show controller oms output can be used for finding the applied gain.
EDFA-DROP Control Mode	`controller Oms R/S/I/P` `ingress-ampli-mode power-control`	The default mode is gain-control. Use this command to change the mode to power-control mode. You can delete this configuration to revert to gain-control mode.
EDFA-DROP Power	`controller Oms R/S/I/P` `ingress-ampli-power <vale in 0.1 dBm>`	This is the target output power configuration for the EDFA located on COM-Rx. If the output power is not configured, then a default value is used by the system. You can find the applied target output power by using the show controller oms output.
EDFA-DROP Gain	`controller Oms R/S/I/P` `ingress-ampli-gain <val in 0.1 dB>`	This is used for configuring gain for the EDFA located on the COM-Rx port. If the gain is not configured, then a default value is used by the system. The show controller oms output can be used for finding the applied gain.
VoA Attenuation	`controller Oms R/S/I/P` `tx-voa-attenuation <val in 0.1 dB>` `rx-voa-attenuation <val in 01. dB>`	This is used to configure VoA attenuation for COM-Tx and COM-Rx ports. The system picks a default value if the gain is not configured. The show controller oms output can be used for finding the applied attenuation.
Shutdown (COM Port)	`controller Oms R/S/I/P` `shutdown`	COM-Tx and Rx ports are put in Out of Service (OOS) when this command is executed. This turns off the EDFA devices on both COM-Tx and COM-Rx ports and the respective alarms are masked. Here the default value is 'unshut'.
Shutdown (Ch Ports)	`controller Och R/S/I/P` `shutdown`	The channel port will be marked as out-of-service.

Configure Operational Parameters

The different operational parameters supported are given below.

Table 7. Operational Parameters
Parameter	CLI	Description
Photo Diodes (COM Port)	OMS Controller `Tx Power and Rx Power`	Rx Power = Inband power + OOB Tx Power = Inband power + OOB It reports the power transmitted and received on the OMS port. The OOB power received on COM-Rx is looped back to COM-Tx with some loss due to the insertion-loss on the loop back path.
Photo Diodes (CH Ports)	OCH Controller `Tx Power and Rx Power`	It reports the power transmitted and received on the channel ports.
Amplifier Parameters	OMS Controller `Ingress Ampli Mode` `Ingress Ampli Gain` `Ingress Ampli Tilt` `Ingress Ampli OSRI` `Egress Ampli Mode` `Egress Ampli Gain` `Egress Ampli Tilt` `Egress Ampli Gain Range` `Egress Ampli OSRI` `Egress Ampli BR Power` `Egress Ampli BR Ratio`	Egress and ingress amplifier parameters.
VoA Parameters	OMS Controller `Tx VoA Attenuation and Rx VoA Attenuation`	VoA attenuation parameters.

Configure Optical Safety Parameters

Use the following parameters for configuring optical safety.

Table 8. Optical Safety Parameters
Parameter	CLI	Description
OSRI	`controller Oms R/S/I/P` `egress-ampli-osri` `ingress-ampli-osri`	Use this configuration to enable or Disable Optical Safety Remote Interlock (OSRI) on the amplifiers located on COM-Tx and COM-Rx ports. The default value is 'Off'. The show controller oms output can be used for finding the OSRI configuration and status.

Configure Rx VOA Fixed Ratio to Zero

You can configure the Rx VOA attenuation to a fixed ratio of zero, effectively disabling the Rx VOA entirely.

Warning

Disabling Rx VOA attenuation in certain scenarios may destabilize the network. Practice caution and contact the Cisco TAC team for more information.

Procedure

Step 1

This configuration sets the rx-voa fixed-ratio to zero.

Example:

RP/0/RP0/CPU0:NE80#configur
Tue Aug 6 07:44:28.125 UTC
Current Configuration Session  Line       User     Date                     Lock
00001000-00001569-00000000 vty0 cisco Tue Aug 6 05:33:16 2024
RP/0/RP0/CPU0:NE80(config)#controller optics 0/2/0/0 rx-voa fixed-ratio 0
RP/0/RP0/CPU0:NE80(config)#controller optics 0/2/0/7 rx-voa fixed-ratio 0
RP/0/RP0/CPU0:NE80(config)#commit
Tue Aug 6 07:44:48.545 UTC
RP/0/RP0/CPU0:NE80(config)#end

Step 2

Verify whether the rx-voa fixed ratio is set to fixed ration zero using show running-config controller command.

Example:

RP/0/RP0/CPU0:N112#show running-config controller optics 0/2/0/0
Thu May 16 09:19:51.223 UTC
description optics0/2/0/0
dwdm-carrier 100MHz-grid frequency 1909000
rx-voa fixed-ratio 0

Step 3

Verify whether the rx-voa fixed-ratio is set to fixed ration zero using the show controllers optics command.
