ma

Use this command to enter Maintenance Association (MA) Configuration mode for the specified MA.

Syntax

ma {string-name name | vid-name vlan | id-name id}
no ma {string-name name | vid-name vlan | id-name id}

Parameters

string-name name Specifies the MA name as a string of up to 43 characters.
vid-name vlan Specifies the MA name as a VLAN ID. Valid values are 0 - 4094.
id-name index Specifies the MA name as an index value. Valid values are 0 - 65535.

Defaults

None.

Mode

Maintenance Domain Configuration mode.

Usage

A maintenance association (MA) uniquely identifies a service within an MD. A service may be defined by an individual VLAN. There may be multiple MAs within a domain. Subsets of devices residing within the domain are collectively configured to form these associations. The devices belonging to a particular association will communicate among themselves to implement the various features provided by CFM.

One of three naming conventions can be used to identify a CFM MA:

  • String-name – A string of up to 43 printable characters. This format provides descriptive freedom in naming the association.
  • Vid-name – An integer value between 0 - 4094. This format restricts the association name to the VLAN range. For management purposes, show command output will label this format as a VLAN type. Use this format when the association is directly related to monitoring a VLAN.
  • Id-name – An integer value between 0 - 65535. This format restricts the association name to an integer range. Use this format when a sequential naming scheme is being used to manage the associations.

A non-configurable index value is associated with every MD and MA. This index value appears in the prompt to provide context to the prompt. For example, the prompt (rw-config-cfm-ma.1) is for the MA index 1 configuration context. Use show cfm md ma to display the index value for each configured MA.

Examples

This example shows how to enter configuration command mode for the myMD1 maintenance domain and enter MA configuration mode for the maintenance association named myMA1:

System(rw-config)->cfm md string-name myMD1
System(rw-config-cfm-md.1)->ma string-name myMA1
System(rw-config-cfm-ma.1)->

This example shows how to enter configuration command mode for the myMD1 maintenance domain and enter MA configuration mode for the maintenance association identified by vid-name type 1000. Note that since this is the second maintenance association created in maintenance domain myMD1, the MA index number is 2 (shown in the prompt).

System(rw-config)->cfm md string-name myMD1
System(rw-config-cfm-md.1)->ma vid-name 1000
System(srw-config-cfm-ma.2)->
