traceroute mac port

traceroute mac mac {up-end-point} port port {domain} domain_name {association} association_name {ttl ttl}

Description

Allows you to send out a Link Trace Message (LTM) for the specified MA from the MEP configured on the port for the specified MAC address to the end of the MA.

Syntax Description

mac Enter the unique system MAC address on the port configured as a MEP for the specified MA. Enter this value in the format XX:XX:XX:XX:XX:XX.
up-end-point Use this keyword to force the LTM to be send from an UP MEP if both a DOWN MEP and an UP MEP are configured on the same port.
port Enter the port number of the MEP from which you are issuing the LTM.
domain Enter this keyword.
domain_name IEEE 802.1ag or ITU-T Y.1731 association name.
association Enter this keyword.
association_name Enter the name of the association from which you are issuing the ping.
ttl Enter this keyword.
ttl Enter the upper limit of MIPs the LTM can pass prior to reaching its destination.

Default

TTL default value is 64.

Usage Guidelines

Use this command to send an LTM from the MEP on the port for the given MAC address. If no MEP is configured on the port, the system returns an error message.

If both an UP and DOWN MEP are configured on the same port, the system uses the DOWN MEP. If you want to use the UP MEP in this situation, enter the up-end-point keyword. After you issue the command, the system prints out the route the LTM message took.

Each MIP along the route passes the LTM along only in the direction of the path and sends a packet back to the originating MAC notifying that it passed the LTM. If the destination MAC type is configured as unicast on the association to which this MEP belongs to, link trace replies will not be received from any of the MIPs configured on the intermediate switches. If there is a MIP on the switch that originated the trace route, the MIP sends a link trace reply.

Example

The following commands send an LTM:

1. A trace route invoked from a customer device CE1 to another customer device CE3 connected through an MPLS cloud (MTU1 -' PE1 'PE3), where a VPLS MIP is configured to encode a system-name, will have a response as follows:

(debug) Switch # traceroute mac 00:04:96:28:02:15 port 1 "extr_cfm5" "extr_ma"
Send out Link Trace Message(LTM), collecting responses [press Ctrl-C to abort].

If in PE1 alone, a VPLS MIP is configured to encode a system name, the response will be as follows:

(debug) Switch # traceroute mac 00:04:96:1e:14:90 port 1:8 extr_cfm2 "extr_ma"
