Purpose
Command or Action
Configures a maintenance association within a
maintenance domain and enters Ethernet connectivity
fault management (CFM) service configuration mode.
service short-ma-name evc evc-name vlan vlanid
direction down
Example:
Device(config-ecfm)# service s41 evc 41 vlan 41
direction down
Step 4
Configures the transmission of continuity check messages
(CCMs).
continuity-check
Example:
Device(config-ecfm-srv)# continuity-check
Step 5
Configures the per-service parameters and sets the
interval at which CCMs are transmitted.
continuity-check
[
interval cc-interval
]
Example:
Device(config-ecfm-srv)# continuity-check
interval 10s
Step 6
Returns to Ethernet connectivity fault management
configuration mode.
exit
Example:
Device(config-ecfm-srv)# exit
Step 7
Sets the amount of time that data from a missing MEP
is kept in the continuity check database or that entries
are held in the error database before they are purged.
mep archive-hold-time minutes
Example:
Device(config-ecfm)# mep archive-hold-time 60
Step 8
Returns to global configuration mode.
exit
Example:
Device(config-ecfm)# exit
Step 9
Enables CFM processing globally on the device.
ethernet cfm global
Example:
Device(config)# ethernet cfm global
Step 10
Enables caching of CFM data learned through traceroute
messages.
ethernet cfm traceroute cache
Example:
Device(config)# ethernet cfm traceroute cache
Step 11
Sets the maximum size for the CFM traceroute cache
table.
ethernet cfm traceroute cache size entries
Example:
Device(config)# ethernet cfm traceroute cache
size 200
