show cfm

show cfm { domain_name { association_name {{ports port_list {[intermediate-point | [end-point [up|down]]]}}}

Description

Displays the current CFM configuration on the switch.

Syntax Description

domain_name Enter the name of the domain you want to display.
association_name IEEE 802.1ag or ITU-T Y.1731 association name.
port_list Enter the ports in the domain and association you want to display.
up Enter this to display the UP MEP for the specified MA.
down Enter this to display the DOWN MEP for the specified MA.
intermediate-point Enter this to display the MIPs for the specified MA.

Default

N/A.

Usage Guidelines

This command displays the following information:
  • Domain names
  • MA levels
  • Association names
  • VLAN names
  • Transmit Interval
  • UP MEPs
  • MEPIDs
  • MEP transmit intervals
  • MEP State
