Syntax Description


`name`	Assigns the name you want for this domain, using the DNS name format. Enter alphanumeric characters for this format; the maximum is 43 characters.
`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)
Note

MEPs with intervals 3 and 10 cannot be created in this domain as the domain name format is of dns type.

Example

The following command creates a domain, using the DNS name format, named extreme and assigns that domain an MD level of 2:

create cfm domain dns extreme md-level 2
