Table 48: 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	A 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.
