Description
Display IEEE 802.1ag Operation, Administration, and Management (OAM) connectivity fault management maintenance linktrace database information.
Options
mac-address | Display connectivity fault management path database information for the specified MAC address of the remote host. |
maintenance-association ma-name | Display connectivity fault management path database information for the specified maintenance association. |
maintenance-domain md-name | Display connectivity fault management path database information for the specified maintenance domain. |
Required Privilege Level

Output Fields
Table 1 lists the output fields for the show oam ethernet connectivity-fault-management
path-database
command. Output fields are listed in the approximate
order in which they appear.
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. |
