1.2T Line Card
The following section describes the supported configurations and procedures to configure the card modes on the line card.
Card Modes
The line cards support module and slice configurations.
The line cards have two trunk ports (0 and 1) and 12 client ports (2 through 13) each. You can configure the line card in two modes:
-
Muxponder—In this mode, both trunk ports are configured with the same trunk rate. The client-to-trunk mapping is in a sequence.
-
Muxponder slice—In this mode, each trunk port is configured independent of the other with different trunk rates. The client-to-trunk mapping is fixed. For Trunk 0, the client ports are 2 through 7. For Trunk 1, the client ports are 8 through 13.
Sub 50G Configuration
You can configure the sub 50G or coupled mode on the line card only in the muxponder mode. The following table displays the port configuration for the supported data rates.

 Note |
In all x50G configurations, client traffic on the middle port is affected with ODUK-BDI and LF alarms after the power cycle or link flap on the trunk side. This issue is raised when the two network lanes work in coupled mode and move from low to high power. To solve this issue, create a new frame either at the near-end or far-end by performing shut or no shut of the trunk ports. |
Coupled Mode Restrictions
The following restrictions apply to the coupled mode configuration:
-
Both trunk ports must be configured with the same bits-per-symbol or baud rate and must be sent over same fiber and direction.
-
The chromatic dispersion must be configured to the same value for both trunk ports.
-
When trunk internal loopback is configured, it must be done for both trunk ports. Configuring internal loopback on only one trunk results in traffic loss.
-
Fault on a trunk port of a coupled pair may cause errors on all clients including those running only on the unaffected trunk port.
Configure Split Client Port Mapping
You can configure the trunk port to client port mapping for sub 50G data ratesin the default mode or in the split client port mapping mode.
To configure the split client port mapping, use the following commands.
configure
hw-module location location mxponder
split-client-port-mapping
commit
The following is a sample in which split-client-port-mapping is configured with a 450G trunk payload.
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/1/NXR0 mxponder
RP/0/RP0/CPU0:ios(config-hwmod-mxp)#split-client-port-mapping
RP/0/RP0/CPU0:ios(config-hwmod-mxp)#commit
RP/0/RP0/CPU0:ios(config-hwmod-mxp)#endTo remove the split client port-mapping configuration and configure default client port mapping, use the following commands.
configure
hw-module location location mxponder
no split-client-port-mapping
commit
The following is a sample in which split client port-mapping configuration is removed.
RP/0/RP0/CPU0:ios#configure

Configuring the Card Mode
You can configure the line card in the module (muxponder) or slice configuration (muxponder slice).
To configure the card in the muxponder mode, use the following commands.
configure
hw-module location location mxponder client-rate {100GE | OTU4}
hw-module location location mxponder trunk-rate {50G | 100G150G | 200G | 250G | 300G | 350G | 400G | 450G | 500G | 550G | 600G }
commit
To configure the card in the muxponder slice mode, use the following commands. configure hw-module location location mxponder-slice mxponder-slice-number client-rate { 100GE|OTU4}
hw-module location location mxponder-slice trunk-rate { 100G | 200G | 300G | 400G | 500G | 600G }

In an optical transmission system, 3R regeneration helps extend the reach of the optical communication links by reamplifying, reshaping, and retiming the data pulses. Regeneration helps to correct any distortion of optical signals by converting it to an electrical signal, processing that electrical signal, and then retransmitting it again as an optical signal.
In Regeneration (Regen) mode, the OTN signal is received on a trunk port and the regenerated OTN signal is sent on the other trunk port of the line card and the other way round. In this mode, only the trunk optics controller and coherentDSP controllers are created.
Configuring the Card in Regen Mode
The supported trunk rates for 1.2T card is100G to 600G in multiples of 100G.
To configure regen mode on 1.2T, use the following commands:
configure
hw-module location location
regen
trunk-rate trunk-rate
commit
exit
Example
The following is a sample to configure the regen mode on 1.2T line card with the trunk-rate 300.
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/NXR0
RP/0/RP0/CPU0:ios(config-hwmod)#regen
RP/0/RP0/CPU0:ios(config-regen)#trunk-rate 300
RP/0/RP0/CPU0:ios(config-regen)#commit
RP/0/RP0/CPU0:ios(config-regen)#exit
Verifying the Regen Mode
The following is a sample to verify the regen mode.

Configuring the BPS
You can configure the Bits per Symbol (BPS) to 3.4375 to support 300G trunk configurations on 75 GHz networks using the following commands:

Configuring the Trunk Rate for BPSK
You can configure trunk rates of 50G, 100G, and 150G to support Binary Phase-Shift Keying (BPSK) modulation. The BPSK modulation enables information to be carried over radio signals more efficiently.
You can configure trunk rates for BPSK using CLI, NetConf YANG, and OC models.
The following table list the 50G, 100G, and 150G trunk rates with the supported BPSK modulation:
|
Trunk Rate |
BPSK Modulation |
|---|---|
|
50G |
1 to 1.4453125 |
|
100G |
1 to 2.890625 |
|
150G |
1.453125 to 4.3359375 |
To configure the trunk rate for BPSK modulation, enter the following commands:
configure
hw-module location location mxponder
trunk-rate {50G | 100G | 150G}

The following example shows how to configure trunk rate to 50G:
