Creating the Maintenance Domain
To enable CFM on an Ethernet interface, maintenance domains, maintenance associations, and MEPs must be created and configured.
To create a maintenance domain, include the maintenance-domain domain-name statement at the [edit protocols oam ethernet connectivity-fault-management] hierarchy level.
Give the maintenance domain a name. Names can be in one of several formats:
Configuring the Maintenance Domain Name Format
You can specify the maintenance domain name format as one of the following:
- A plain ASCII character string.
- A domain name service (DNS) format, a MAC address plus a two-octet identifier in the range from 0 through 65,535, or none.
- A MAC address plus a two-octet identifier in the range from 0 through 65,535.
- Or none.
If none is specified, the maintenance domain name is not used.
The default name format is an ASCII character string.
To configure the maintenance domain name format, include the name-format (character-string | none | dns | mac+2octet) statement at the [edit protocols oam ethernet connectivity-fault-management maintenance-domain domain-name] hierarchy level.
 | Note: If you configure the maintenance domain name length greater than 45 octet, then the following error message is displayed:: error: configuration check-out failed |
Configuring the Maintenance Domain Level
The maintenance domain level is a mandatory parameter that indicates the nesting relationship between various maintenance domains. The level is embedded in each of the CFM frames. CFM messages within a given level are processed by MEPs at that same level. For example, the operator domain can be level 0, the provider domain can be level 3, and the customer domain can be level 7.
To configure the maintenance domain level, include the level number statement at the [edit protocols oam ethernet connectivity-fault-management maintenance-domain domain-name] hierarchy level.
