Table 138: show ethernet cfm linktrace-cache - display description
Field Description
Hops The number hops taken to reach the target MEP.
MA Name of the MA to which this device belongs.
IP/Alias IP address or 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 MAC address of the ingress port on the target device.
Egress MAC MAC address of the egress port on the target device.
Ing. 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.
