You can manually monitor the status of peers using IEEE 802.1ag CFM Linktrace commands. LTM message is generated when link trace is performed.
device# cfm linktrace domain md1 ma ma1 src-mep 101 target-mep 200
Following are the parameters which you can configure for the CFM Linktrace command.
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 name attribute is case-sensitive.
The src-mep mep-id parameter specifies the Source ID in the range 1-8191.
The target-mip HHHH.HHHH.HHHH.HHHH parameter specifies the MAC-address of the MIP linktrace destination.
The target-mep mepid parameter specifies the ID of the linktrace destination.
The timeout timeout parameter specifies the timeout used to wait for linktrace reply and the value range from 1-30 seconds.
The ttl TTL parameter specifies the initial TTL field value in the range 1-64. The default value is 8.
