To send Ethernet connectivity fault management (CFM) loopback messages to a maintenance endpoint

(MEP) or maintenance intermediate point (MIP) destination, use the ping ethernet vlan command in

privileged EXEC command mode.

ping ethernet {mac-address | mpid} {domain domain-name | level level-id} vlan vlan-id [source

mpid]

Syntax Description

Command Default A basic CFM ping operation to the specified MAC address (MEP or MIP) is performed.

Command Modes Privileged EXEC (#)

Command History

Usage Guidelines A local MEP must be configured for the same level and VLAN before you can use this command.

The optional source keyword is available only when you enter a domain name. The source keyword is

useful when there are multiple local MEPs in the same domain, level, and VLAN as the ping target. For

outward facing MEPs, choosing the source MPID implicitly selects the interface from which the ping is

sent.

mac-address MAC address of the remote maintenance point in the format abcd.abcd.abcd.

mpid Integer from 0 to 8191 that identifies the MEP.

domain Indicates a domain is specified.

domain-name String with a maximum of 154 characters that identifies the domain.

level Indicates that a maintenance level is specified.

level-id Integer value of 0 to 7 that identifies the maintenance level.

vlan-id Integer value of 1 to 4094 that identifies the VLAN.

source mpid (Optional) Indicates a source maintenance point.
