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 node responding to the LTM or the source MAC address of the LTR. |
Next hop MAC address | MAC address of the egress interface of the node to which the LTM is forwarded or the next-hop MAC address derived from the next egress identifier in the Egress-ID TLV of the LTR PDU. |
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. |
