See the 7210 SAS-Mxp, R6, R12, S, Sx, T OAM and Diagnostics Guide for more information about ETH-CFM configuration guidelines for 7210 SAS platforms.
Configuring ETH-CFM requires commands at two different hierarchy levels of the CLI.
This section provides a sample of the global ETH-CFM configuration, which defines the domains, associations, linkage of the service ID or function, and the globally applicable CCM parameters, including the interval and building of the remote MEPs database.
The following example shows ETH-CFM configuration output.
*A:ALU-7_A>config>eth-cfm# info
----------------------------------------------
domain 1 name "1" level 1
association 2 name "1345"
bridge-identifier 100
exit
ccm-interval 60
remote-mepid 2
remote-mepid 3
exit
exit
----------------------------------------------
*A:ALU-7_A>config>eth-cfm#
Defining the MEP and configuring service-specific ETH-CFM parameters is performed within the service on the specific SAP or SDP binding. The following example shows service VPLS 100 showing this configuration output on the SAP.
#*A:ALU-7_A>config>service# info
----------------------------------------------
vpls 100 customer 1 create
description "VPLS service 100 - Used for MEP configuration example"
sap 2/2/1:20 create
description "2/2/1:20"
eth-cfm
mep 1 domain 1 association 1 direction down
no shutdown
exit
exit
exit
exit
no shutdown
exit
customer 1 create
description "Default customer"
exit
exit
----------------------------------------------
*A:ALU-7_A>config>service#
All of the preceding examples were based on IEEE 802.1ag. They are not capable of running Y.1731 functions. To build a Y.1731 context, the domain format must be none.
The following example shows global ETH-CFM configuration outputs and the advanced Y.1731 functions that can be configured. The configuration rejects the configuration of Y.1731 functions within an IEEE 802.1ag context.
*A:7210-2# config>eth-cfm# info
----------------------------------------------
domain 1 format none level 1
association 1 format icc-based name "1234567890123"
bridge-identifier 100
exit
ccm-interval 1
exit
exit
*A:7210-2# config>service# info
----------------------------------------------

To be able to transmit and also receive AIS PDUs, a Y.1731 MEP must have ais-enable set.
To be able to transmit and also receive ETH-Test PDUs, a Y.1731 MEP must have eth-test-enable set.
