CFM Commands
25
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-id [mip-creation type]]
no ma index index [vlan vlan-id]
index – MA identifier. (Range: 1-2147483647)
ma-name – MA name. (Range: 1-43 alphanumeric characters, maximum length is 44
minus the length of the domain name)
vlan-id - Service VLAN ID. (Range: 1-4093)
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
• 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.
