ping ethernet

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

maintenance endpoint (MEP), use the ping ethernet command in privileged EXEC mode.

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

source-mpid] level level-id {vlan vlan-id}}

Syntax Description

Command Default A CFM ping operation to the specified MEP is performed.

Command Modes Privileged EXEC (#)

Command History

Usage Guidelines Use this command to test connectivity between MEPs.

If the continuity check database does not have entries for the specified MPID, an error message is

displayed notifying you to use the ping ethernet mac-address command instead.

If a domain name has more than 43 characters, a warning message is displayed notifying you that the

maintenance domain ID (MDID) are truncated to 43 characters in continuity check messages (CCMs) if

“id <fmt> <MDID>” is not configured.

This command can be issued by specifying keywords and arguments as one command or as an

“extended” command in which you specify options line by line.

Examples The following examples show how to send an Ethernet CFM loopback message to a destination MEP

using the “extended ping” format:

mac-address MAC address of the destination MEP in the format abcd.abcd.abcd.

mpid Specifies a maintenance point identifier.

mpid Integer from 1 to 8191 that identifies the MEP.

domain Specifies the domain where the destination MEP resides.

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

vlan Specifies a VLAN.

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

source (Optional) Specifies a MEP’s CoS that is sent in Ethernet CFM messages.

source-mpid (Optional) Integer from 1 to 8191 that identifies the source MEP.

level Indicates that a maintenance level is specified.

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