Use this command to enter Maintenance Domain (MD) Configuration mode for a specific named MD. If the maintenance domain does not exist, this command will create it.

Syntax

cfm md {string-name name | dns-like-name dns-name | mac-int-name mac-name | no-name}

no cfm md {string-name name | dns-like-name dns-name | mac-int-name mac-name | no-name}

Parameters

string-name `name`	Specifies an MD string name of up to 43 printable characters.
dns-like-name `dns-name`	Specifies an MD string of up to 43 printable characters that represents a standard domain name server convention.
mac-int-name `mac-name`	Specifies an MD string that follows a MAC address format plus an integer index ID value separated by a period (.) in the format xx-xx-xx-xx-xx-xx.ID or xx:xx:xx:xx:xx:xx.ID, where x is a hex value and the ID range is 0 - 65535.
no-name	Specifies that a NULL string (“”) will be used for the MD name.

Defaults

None.

Mode

Global configuration command.

Usage

A maintenance domain (MD) is a collection of network devices, typically owned and operated by a single organization. Management of devices within a domain falls under the control of that single organization. MDs must be contiguous, so that all the devices belonging to a domain have uninterrupted network connectivity with each other. MDs may be nested or adjacent, but can not share network devices with other domains. MDs are intended to provide connectivity to systems outside of the domain. MDs are uniquely identified by an MD Name.

One of four naming conventions can be used to identify a CFM MD:

String-name – A string of up to 43 printable characters. This format provides descriptive freedom in naming the association.
Dns-like-name – A string of up to 43 printable characters that represents a standard domain name server convention. This option is for management purposes. A check is done to assure that you have entered a legally formatted DNS name.
Mac-int-name – A MAC address format plus an integer index ID value. You must follow a supported MAC address format as described in the parameter table.
No-name – A no name option that sets a NULL string as the MD name. It can only be used for a single MD on each device.

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-md.1) is for the MD index 1 configuration context. Use show cfm md to display the index value for each configured MD.

The “no” form of this command deletes the specified MD.

Refer to Maintenance Domain Configuration Commands for descriptions of the commands available in Maintenance Domain configuration mode.
