traceroute ethernet
traceroute ethernet
To send Ethernet connectivity fault management (CFM) traceroute messages to a destination
maintenance endpoint (MEP), use the traceroute ethernet command in privileged EXEC mode. This
command does not have a no form.
traceroute ethernet mac-address {domain domain-name {vlan vlan-id | level level-id}
traceroute ethernet mac-address { domain domain-name vlan vlan-id | level level-num vlan vlan-id }
Syntax Description
Command Modes Privileged EXEC (#)
Command History
Usage Guidelines If a CoS is not configured, the default is the highest priority allowed for the egress interface.
FDB is another term for the L2 forwarding table. When the fdb-only option is configured, only MAC
addresses learned in a bridge’s FDB (not information saved in the maintenance intermediate point [MIP]
continuity check database [CCDB]) are used to determine the egress port.
The destination can be either a MEP or a MIP. If the destination is a MIP, the FDB must have a MAC
address entry for that MIP; that is, the FDB has learned the MIP’s MAC address via Linktrace responses.
For a bridge domain-VLAN service, the VLAN ID can be used to initiate traceroute.
The following example shows a traceroute ethernet command and output:
Router# traceroute ethernet 1.1.1 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
Traceroute sent via Ethernet0/0.9, path found via MPDB
B = Intermediary Bridge
! = Target Destination
* = Per hop Timeout
