Table 1: show oam ethernet connectivity-fault-management linktrace path-database Output Fields

Field Name

Field Description

Linktrace to

MAC address of the 802.1ag node to which the linktrace message is targeted.

Interface

Interface used by the local MEP to send the linktrace message (LTM).

Maintenance Domain

Maintenance domain identifier specified in the traceroute command.

Maintenance Association

Maintenance association identifier specified in the traceroute command.

Level

Maintenance domain level configured for the maintenance domain.

Local Mep

MEP identifier of the local MEP originating the linktrace.

Hop

Sequential hop count of the linktrace path.

TTL

Number of hops remaining in the linktrace message (LTM). The time to live (TTL) is decremented at each hop.

Source MAC address

MAC address of the 802.1ag maintenance intermediate point (MIP) that is forwarding the LTM.

Next hop MAC address

MAC address of the 802.1ag node that is the next hop in the LTM path.

Transaction Identifier

4-byte identifier maintained by the MEP. Each LTM uses a transaction identifier. The transaction identifier is maintained globally across all maintenance domains. Use the transaction identifier to match an incoming linktrace responses (LTR), with a previously sent LTM.

Sample Output

show oam ethernet connectivity-fault- management path-database

show oam ethernet connectivity-fault- management linktrace path-database (Two traceroute commands)

Release Information

Command introduced in Junos OS Release 8.4.
