Fields (continued)
Field Name Field Description
MEP identifier of the local MEP originating the linktrace.
Local Mep
Sequential hop count of the linktrace path.
Hop
Number of hops remaining in the linktrace message (LTM). The time to live (TTL) is decremented at
TTL
each hop.
MAC address of the 802.1ag maintenance intermediate point (MIP) that is forwarding the LTM.
Source MAC address
Next hop MAC address MAC address of the 802.1ag node that is the next hop in the LTM path.
