Use this command to transmit CFM linktrace messages to the specified MEP or MAC address.
| mep mep-id | Specifies the MEP to send the linktrace messages to. |
| mac mac-addr | Specifies the MAC address of the device to send the linktrace messages to. Valid values are MAC addresses in the address format: xx-xx-xx-xx-xx-xx or xx:xx:xx:xx:xx:xx or xxxx.xxxx.xxxx where x is a hex value. |
| ttl time-to-live | (Optional) Specifies the time-to-live for the linktrace messages. Valid values are 0 - 255. Default value is 64. |
| fdb-only | (Optional) Specifies that only the bridge's filter database is used to determine the egress port. |
Maintenance End-Point Configuration mode.
The CFM linktrace protocol is used to help verify a path and identify where in a path a connectivity problem exists by indicating that an incompete path between the initiating device and the target device exists. Linktrace messages (LTM) are sent to either a specified end-point or to the MAC address of a maintenance intermediate-point.
The fdb-only option determines whether each hop along the linktrace path uses the local filter database exclusively or is allowed to also use the local MIP CCM database to determine reachability to the target. If the fdb-only option is not specified, both databases are used to determine reachability to the target.
The mep option requires that the remote MEP has already communicated with this MEP and there is an entry in the MEP database for the remote MEP. The linktrace will fail if the mep option is used and the remote MEP has not yet communicated with this MEP.
The LTM shares the same priority as the continuity check message and can not be separately configured. The priority for continuity check messages and LTMs is set using priority.
This example shows how to send linktrace messages to MEP 2000 from the myMA1 MEP 1000:
System(rw-config)->cfm md string-name myMD1 System(su-config-cfm-md.1)->ma string-name myMA1 System(su-config-cfm-ma.1)->mep 1000 System(su-config-cfm-mep.1000)->linktrace mep 2000 Linktrace to 00-00-00-10-00-03, Transaction ID 29481 MD Name: abc MA Name: abc MEP ID : 1, Interface ge.4.18 ===================================================== Hop TTL Source MAC Next hop MAC Relay ---- ---- ----------------- ----------------- ------- 1 63 00-1f-45-9e-3e-d1 00-00-00-10-00-00 MIP-DB 2 62 00-00-00-10-00-00 00-00-00-00-00-00 Hit System(su-config-cfm-mep.1000)->
