•
MA – Maintenance association name.
•
IP/Alias – IP address or DNS alias of the target device’s CPU.
•
Forwarded – Shows whether or not this link trace message was forwarded. A message is not
forwarded if received by the target MEP.
•
Ingress MAC Address – MAC address of the ingress port on the target device.
•
Egress MAC Address – MAC address of the egress port on the target device.
•
Ingress Action – Action taken on the ingress port:
•
IngOk – The target data frame passed through to the MAC Relay Entity.
•
IngDown – The bridge port’s MAC_Operational parameter is false. This value could be
returned, for example, by an operationally Down MEP that has another Down MEP at a
higher MD level on the same bridge port that is causing the bridge port’s MAC_Operational
parameter to be false.
•
IngBlocked – The ingress port can be identified, but the target data frame was not
forwarded when received on this port due to active topology management, i.e., the bridge
port is not in the forwarding state.
•
IngVid – The ingress port is not in the member set of the LTM’s VIDs, and ingress filtering
is enabled, so the target data frame was filtered by ingress filtering.
•
Egress Action – Action taken on the egress port:
•
EgrOk – The targeted data frame was forwarded.
•
EgrDown – The Egress Port can be identified, but that bridge port’s MAC_Operational
parameter is false.
•
EgrBlocked – The egress port can be identified, but the data frame was not passed
through the egress port due to active topology management, i.e., the bridge port is not in
the forwarding state.
•
EgrVid – The Egress Port can be identified, but the bridge port is not in the LTM’s VID
member set, and was therefore filtered by egress filtering.
•
Reply – Reply action:
•
FDB – Target address found in forwarding database.
•
MPDB – Target address found in the maintenance point database.
•
HIT – Target located on this device.
