Description

Syntax Description
Default

Usage Guidelines
You can have up to 8 domains on a switch, and each one must have a unique MA level.
You assign each domain a maintenance association (MA) level, which function in a hierarchy for
forwarding CFM messages. The levels are from 0 to 7; with the lowest number being superior in the
hierarchy.
The IEEE standard 801.2ag specifies different levels for different network users, as follows:
●
0 to 2 for end users
●
3 and 4 for Internet service providers (ISPs)
●
5 to 7 for operators (entities carrying the information for the ISPs)

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