ARAMETERS
These parameters are displayed:
◆ Hops – The number hops taken to reach the target MEP.
MA – Maintenance association name.
◆
IP/Alias Address – 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.
