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.
Syntax
ma index index name ma-name [vlan vlan-list [mip-creation type]]
no ma index index [vlan vlan-list]
index – MA identifier. (Range: 1-2147483647)
ma-name – MA name. (Range: 1-43 alphanumeric characters)
vlan-list - Separate nonconsecutive VLAN identifiers with a comma and no
spaces; use a hyphen to designate a range of IDs. (Range: 1-4094).
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.

Command Usage
â—† 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.
â—† 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.
â—† 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.
â—† The first VLAN entered in the list by this command is the primary VLAN, and is
the VLAN on which all CFM functions are executed.
