Rearrangement in the Configuration Guides

• The following are the modifications in the CEM guides.

  • Introduction of the Alarm Configuring and Monitoring Guide:

    This guide provides the following information:

    • Alarms supported for SONET and SDH, and their maintenance

    • Alarm profiling feature

    • Auto In-Service States for cards, ports, and transceivers

  • Rearrangement of Chapter and Topics in the Alarm Configuring and Monitoring Guide:

    • The Auto In-Service States Guide is now a chapter inside the Alarms Configuring and Monitoring Guide.

    • Alarms at SONET Layers topic in the following CEM guides, is added to the Alarms Configuring and Monitoring Guide:

      • 1-Port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module Configuration Guide

    • The Alarm History and Alarm Profiling chapters are removed from the below CEM Technology guides, and added into the Alarm Configuring and Monitoring Guide:

      • 1-Port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module Configuration Guide

The Cisco NCS 4201 and NCS 4202 Network Convergence Systems are full-featured, compact one-RU high converged access platforms designed for the cost-effective delivery of TDM to IP or MPLS migration services. These temperature-hardened, high-throughput, small-form-factor, low-power-consumption systems are optimized for circuit emulation (CEM) and business applications. NCS 4201 and NCS 4202 chassis allow service providers to deliver dense scale in a compact form factor and unmatched CEM and Carrier Ethernet (CE) capabilities. They also provide a comprehensive and scalable feature set, supporting both Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package .

For more information on the Cisco NCS 4201 Chassis, see the Cisco NCS 4201 Hardware Installation Guide.

For more information on the Cisco NCS 4202 Chassis, see the Cisco NCS 4202 Hardware Installation Guide.

NCS4201 is a fixed router and does not have any field replaceable units.

The following table lists the hardware supported for Cisco NCS 4202 chassis.

Note

The error message "PLATFORM-1-NOSPACE: SD bootflash : no space alarm assert" may occur in the following scenarios: Any sector of SD Card gets corrupted Improper shut down of router power outage. This issue is observed on platforms which use EXT2 file systems. We recommend performing a reload of the router. As a result, above alarm will not be seen during the next reload due to FSCK(file systems check) execution. However, If the error persists after a router reload, we recommend to format the bootflash or FSCK manually from IOS.

• The default command-name command is used to default the parameters under that interface. However, when speed is configured on the interface, the following error is displayed:

  Speed is configured. Remove speed configuration before enabling auto-negotiation

• VCoP/TSoP smart SFPs are not supported.

• Virtual services should be deactivated and uninstalled before performing replace operations.

• IPSec is not supported on the Cisco NCS 4201 and Cisco NCS 4202 routers.

• On Cisco NCS 4202 Series, the following restrictions apply for IPSec:

  • Interface naming is from right to left. For more information, see the Cisco NCS 4200 Series Software Configuration Guide

  • Packet size greater than 1460 is not supported over IPsec Tunnel.

  • Minimal traffic drop might be seen for a moment when higher rate traffic is sent through the IPsec tunnels for the first time.

  • IPsec is only supported for TCP and UDP and is not supported for SCTP.
