Preparing the Ethernet CFM Network

Beginning in privileged EXEC mode, follow these steps to prepare the network for Ethernet CFM:
Command
Step 1 configure terminal
Step 2 ethernet cfm traceroute cache [size entries |
hold-time minutes]
Step 3 ethernet cfm domain domain-name level level-id
Step 4 mep archive-hold-time minutes
Step 5
exit
Step 6 interface interface-id
Step 7 ethernet cfm mip level level-id
Step 8
exit

CFM is not supported and cannot be configured on routed ports.
CFM is supported on EtherChannel port channels. You can configure an EtherChannel port channel
as MEP or MIP. However, CFM is not supported on individual ports that belong to an EtherChannel
and you cannot add a CFM port to an EtherChannel group.
You cannot configure CFM on VLAN interfaces.
CFM is not supported on private VLAN ports. The configuration is allowed, but does not take affect.
Chapter 41 Configuring Ethernet OAM, CFM, and E-LMI
Purpose
Enter global configuration mode.
(Optional) Configure the CFM traceroute cache. You can
set a maximum cache size or hold time.
(Optional) For size, enter the cache size in number of
•
entry lines. The range is from 1 to 4095; the default is
100 lines.
(Optional) For hold-time, enter the maximum cache
•
hold time in minutes. The range is from 1 to 65535; the
default is 100 minutes.
Define a CFM domain, set the domain level, and enter
ethernet-cfm configuration mode for the domain. The
maintenance level number range is 0 to 7.
(Optional) Set the number of minutes that data from a
missing maintenance end point (mep) is kept before it is
purged. The range is 1 to 65535; the default is 100 minutes.
Return to global configuration mode.
Specify a physical interface or a port channel to configure,
and enter interface configuration mode.
Configure an operator-level maintenance intermediate
point (MIP) for the domain level-ID defined in Step 3.
If you plan to configure a MEP at level 7 on this
Note
interface, do not use this command to configure a
MIP on the interface.
Return to global configuration mode.
