Configuring Y.1731 Fault Management

The ITU-T Y.1731 feature provides new CFM functionality for fault and performance management for service providers in large network. The router supports Ethernet Alarm Indication Signal (ETH-AIS) and Ethernet Remote Defect Indication (ETH-RDI) functionality for fault detection, verification, and isolation.

For more information on Y.1731 Fault Management, see

http://www.cisco.com/en/US/docs/ios/cether/configuration/guide/ce_cfm-ieee_y1731.html

To configure Y.1731 fault management, you must enable CFM and configure MIPs on the participating interfaces. AIS messages are generated only on interfaces with a configured MIP.

This section contains the following topics:

•Default Y.1731 Configuration, page 10-26

•Configuring ETH-AIS, page 10-27

•Configuring ETH-LCK, page 10-28

Default Y.1731 Configuration

•ETH-AIS is enabled by default when CFM is enabled.

•When you configure ETH-AIS, you must configure CFM before ETH-AIS is operational.

•ETH-RDI is set automatically when continuity check messages are enabled.
