Chapter Configuring Ethernet Virtual Connection Bridge Domain
Connectivity Fault Management (CFM) over EVC BD
Step 4
mep archive-hold-time minutes
Example:
Router(config-ecfm)# mep
archive-hold-time 60
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.
Step 5
service {ma-name | ma-num | vlan-id
vlan-id | vpn-id vpn-id} [port | vlan
vlan-id [direction down]]
Example:
Router(config-ecfm)# service
Customer1 vlan 101 direction down
Configures an MA within a maintenance domain and
enters CFM service configuration mode.
• If a service is already configured and you configure a
new MA name and also specify the direction down
keyword, a second service is added that maps to the
same VLAN. If you configure a new MA name and
do not specify the direction down keyword, the
service is renamed to the new MA name.
Step 6
continuity-check [interval time |
loss-threshold threshold | static
rmep]
Example:
Router(config-ecfm-srv)#
continuity-check
Enables the transmission of CCMs.
Step 7
continuity-check [interval time |
loss-threshold threshold | static
rmep]
Example:
Router(config-ecfm-srv)#
continuity-check interval 10
Configures the time period between CCM transmissions.
• The values supported are platform dependent.
Step 8
continuity-check [interval time |
loss-threshold threshold | static
rmep]
Example:
Router(config-ecfm-srv)#
continuity-check loss-threshold 10
Sets the number of CCMs that should be missed before
declaring that a remote MEP is down.
Step 9
exit
Example:
Router(config-ecfm-srv)# exit
Returns the device to Ethernet CFM configuration mode.
Step 10
exit
Example:
Router(config-ecfm)# exit
Returns the device to global configuration mode.
Step 11
ethernet cfm global
Example:
Router(config)# ethernet cfm global
Enables CFM processing globally on the device.
