create cfm domain mac md-level

create cfm domain mac mac-addr int md-level level

Description

Creates a maintenance domain (MD) in the MAC address + 2-octet integer format and assigns an MD level to that domain.

Syntax Description

mac-addr	Enter a MAC address in the format XX:XX:XX:XX:XX:XX to specify part of the domain name.
int	Enter the 2-octet integer you want to append to the MAC address to specify the domain name.
level	Specifies the MD level you are assigning to this domain. Enter a value between 0 and 7.

Default

N/A.

Usage Guidelines

You can have up to 8 domains on a switch, and each one must have a unique MD level.

You assign each domain a maintenance domain (MD) level, which function in a hierarchy for forwarding CFM messages. The levels are from 0 to 7; with the highest number being superior in the hierarchy.

The IEEE standard 801.2ag specifies different levels for different network users, as follows:

5 to 7 for end users
3 and 4 for Internet service providers (ISPs)
0 to 2 for operators (entities carrying the information for the ISPs)

Example

The following command creates a domain, using the MAC + 2-octet integer format, with the MAC address of 11:22:33:44:55:66 and an integer value of 63; it also assigns that domain an MD level of 2:

create cfm domain mac 11:22:33:44:55:66 63 md-level 2
