◆ 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.
