Working with Maintenance Domains
A Maintenance Domain (MD) is a part of a network that is controlled by a single
operator and used to support the connectivity between service access points. Each of
the eight hierarchical Maintenance Domain Levels (MD Level) supports OAM capabilities
independently.
Use the following command to set an MD. Note that the
name
attribute must be unique
in the system.
set
cfm-md <md-idx> [format <md-name-format>] [name <md-name>]
[level <md level>] [mhf-creation <mhf creation>] [mhfid-permission
<mhf permission>]
For example, the following command sets the customer domain at level 2.
set cfm-md 2 name string Customer level 2
Use the following command to display a particular MD or all MDs.
show cfm-md {<md-idx-list> | all} {format | name | level | mhf-
creation | mhfid-permission | info}
Use the following command to clear a particular MD or all MDs:
clear cfm-md {<md-idx-list> | all}
For example, the following command clears all the MDs in the system.
clear cfm-md all
13.1.3
Working with Maintenance Associations
A Maintenance Association (MA) is used to monitor connectivity in relation to a specific
service instance. All CFM entities that support that service instance are configured as
MEPs, with the same Maintenance Association Identifier (MAID) and MD Level.
Use the following command to set an MA. Note that the
ma-name
attribute is
mandatory, and must be unique in the system.
set cfm-ma <md-idx> <ma-idx> [format <ma-name-format>] [name <ma-
name>] [interval <ccm-interval>]
Use the following command to display a particular MA or all MAs:
