Configuring A Port Mep - Cisco 3845 - Security Bundle Router Software Manual

Chapter 32 Configuring Ethernet OAM, CFM, and E-LMI

Configuring a Port MEP

A port MEP is a down MEP that is not associated with a VLAN and that uses untagged frames to carry
CFM messages. You configure port MEPs on two connected interfaces. Port MEPs are always configured
at a lower domain level than native VLAN MEPs.
Beginning in privileged EXEC mode, follow these steps to configure Ethernet CFM port MEPs:
Command
Step 1
configure terminal
Step 2
ethernet cfm domain domain-name level level-id
Step 3 service {ma-name | ma-number | vpn-id} port
Step 4
mep mpid identifier
Step 5
continuity-check
Step 6 continuity-check interval value
Step 7 continuity-check loss-threshold threshold-value
Step 8
continuity-check static rmep
Step 9 exit
Step 10 exit
Step 11 interface interface-id

Purpose
Enter global configuration mode.
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.
Define a customer service maintenance association name
or number or VPN ID to be associated with the domain,
define a port MEP, and enter ethernet-cfm-service
configuration mode.
ma-name—a string of no more than 100 characters that
•
identifies the MAID.
• ma-number—a value from 0 to 65535.
• vpn-id vpn—enter a VPN ID as the ma-name.
Define the static remote maintenance end point identifier in
the domain and service. The range is 1 to 4094.
Enable sending and receiving of continuity check
messages.
(Optional) Set the interval at which continuity check
messages are sent. The available values are 100 ms,
1 second, 10 seconds, 1 minute and 10 minutes. The default
is 10 seconds.
Because faster CCM rates are more CPU-intensive,
Note
we do not recommend configuring a large number
of MEPs running at 100 ms intervals.
(Optional) Set the number of continuity check messages to
be missed before declaring that an MEP is down. The range
is 2 to 255; the default is 3.
Enable checking of the incoming continuity check message
from a remote MEP that is configured in the MEP list.
Return to ethernet-cfm configuration mode.
Return to global configuration mode.
Identify the port MEP interface and enter interface
configuration mode.
