– 1102 –
ma index name
This command creates a maintenance association (MA) within the current
maintenance domain, maps it to a customer service instance (S-VLAN),
and sets the manner in which MIPs are created for this service instance.
Use the no form with the vlan keyword to remove the S-VLAN from the
specified MA. Or use the no form with only the index keyword to remove
the MA from the current domain.

ma index index name ma-name [ vlan vlan-id [ mip-creation type ]]
no ma index index [ vlan vlan-id ]
index – MA identifier. (Range: 1-2147483647)
ma-name – MA name. (Range: 1-45 alphanumeric characters)
vlan-id - Service VLAN ID. (Range: 1-4093, no leading zeroes)
type – Specifies the CFM protocol’s creation method for
maintenance intermediate points (MIPs) in this MA:
default – MIPs can be created for this MA on any bridge port
through which the MA’s VID can pass.
explicit – MIPs can be created this MA only on bridge ports
through which the MA’s VID can pass, and only if a maintenance
end point (MEP) is created at some lower MA Level.
none – No MIP can be created for this MA.

◆
The maintenance domain used to enter CFM domain configuration
mode, the MA name and VLAN identifier specified by this command,
and the DSAPs configured with the mep crosscheck mpid command
create a unique service instance for each customer.
◆
If only the MA index and name are entered for this command, the MA
will be recorded in the domain database, but will not function. No MEPs
can be created until the MA is associated with a service VLAN.
◆
Note that multiple domains at the same maintenance level (see the
ethernet cfm domain command) cannot have an MA on the same VLAN.
Also, each MA name must be unique within the CFM-managed network.
◆
Before removing an MA, first remove all the MEPs configured for it (see
the mep crosscheck mpid command).
◆
If the MIP creation method is not defined by this command, the
creation method defined by the ethernet cfm domain command is
applied to this MA. For a detailed description of the MIP types, refer to
the Command Usage section under the ethernet cfm domain command.
