21.1. eth-cfm command descriptions
eth-cfm
Synopsis
Enter the eth-cfm context
Tree
Description
Commands in this context configure ETH-CFM parameters.
Introduced
16.0.R1
Platforms
7450 ESS, 7750 SR, 7750 SR-a, 7750 SR-e, 7750 SR-s, 7950 XRS
default-domain
Synopsis
Enter the default-domain context
Context
Tree
Description
Commands in this context configure MIP creation parameters per index (bridge-identifier bridge-id vlan vlan-id) if the MIP creation statement exists as part of the service connection.
The MIP creation statement must be present on the connection before any configuration can occur for a MIP under this context. Whether a MIP uses the default-domain creation method is determined by the MIP authoritative nature of the eth-cfm domain association. The eth-cfm default-domain MIP creation is considered only if the eth-cfm domain association is not authoritative.
Introduced
21.5.R1
Platforms
7450 ESS, 7750 SR, 7750 SR-a, 7750 SR-e, 7750 SR-s, 7950 XRS
bridge-identifier [bridge-name] string vlan (number | keyword)
Synopsis
Enter the bridge-identifier list instance
Context
configure eth-cfm default-domain bridge-identifier string vlan (number | keyword)
Tree
Description
Commands in this context configure the references required to link the CFM function with the service context, allowing the entry of MIP-specific parameters for the index in the default domain table.
The info and info detail commands do not display any entries for the instance unless they have previously been accessed. The possible candidates for the instance can be located using the show eth-cfm default-domain command.
