Displaying the
Link Trace Cache
Use the Administration > CFM > Show Information (Show Link Trace Cache) page to
show information about link trace operations launched from this device.
Parameters
These parameters are displayed:
◆ Hops – The number hops taken to reach the target MEP.
◆ MA – Maintenance association name.
◆ IP Address / 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.
