Syntax: [no] cfm loopback domain name ma ma-name scr-mep mep-id {target-mip
HH:HH:HH:HH:HH:HH | target-mep mep-id} [number number] [timeout timeout]
The domain name parameter specifies the maintenance domain to be used for a linktrace
message. The name attribute is case-sensitive.
The ma ma-name parameter specifies the maintenance association to be used for a linktrace
message. The ma-name attribute is case-sensitive.
The src-mep mep-id parameter specifies the Source ID in the range 1-8191.
The target- mip HH:HH:HH:HH:HH:HH parameter specifies the MAC address of the MIP linktrace
destination.
The target-mep mep-id parameter specifies the Destination ID in the range 1-8191.
The number number parameter specifies the number of loopback messages to be sent.
The timeout timeout parameter specifies the timeout used to wait for linktrace reply.
You have to configure MAs with different MD levels to monitor the different endpoints with different
NOTE
You have to configure MAs with different MD levels to monitor the different endpoints with different
VLAN IDs in the same VPLS instance.
Syslog message
If CFM is configured, a syslog message will be generated when remote MEPs change their states or
if there are service cross connections.
Sample Syslog Messages
Brocade#
SYSLOG: Jan 7 11:22:55:<9>Router2, DOT1AG: Remote MEP 4 in Domain VPLS-SP, MA
ma_1 aged out
SYSLOG: Jan 7 11:23:13:<9>Router2, DOT1AG: Remote MEP 4 in Domain VPLS-SP, MA
ma_1 become UP state
When a failure is detected within a VPLS cloud, use LSP Ping and Traceroute. Refer to “LSP ping
and traceroute” on page 210 for additional information.
