traceroute ethernet
On the Cisco Catalyst 6500 series switch, an FDB configuration will work only if the origination MEP
is a down MEP. Also, for a MEP to clear the Alarm Indication Signal (AIS) defect condition, there should
be no corresponding entry in the error database. For example, if you change the remote MEP from an
UP MEP to a DOWN MEP, the local entry will time out and enter the AIS defect condition. The database
starts receiving a new CC entry based on the newly configured DOWN MEP, but the local AIS defect is
not yet cleared. It will remain in the AIS state until either the archive hold time expires or you issue the
clear ethernet cfm errors command.
The following example shows a traceroute ethernet command and output:
Router# traceroute ethernet mpid 401 domain Domain_L5 vlan 9
Type escape sequence to abort. TTL 64. Linktrace Timeout is 5 seconds
Tracing the route to aabb.cc03.bb99 on Domain Domain_L5, Level 5, vlan 9
