ethernet cfm
loopback
This command sends CFM loopback messages to a MAC address for a MEP
or MIP.

ethernet cfm loopback { dest-mep destination - mpid | src-mep
source - mpid { dest-mep destination - mpid | mac-address } |
mac-address } md domain-name ma ma-name
[ count transmit-count ] [ size packet-size ]
destination - mpid – The identifier of a MEP that is the target of the
loopback message. (Range: 1-8191)
source - mpid – The identifier of a source MEP that will send the
loopback message. (Range: 1-8191)
mac-address – MAC address of the remote maintenance point that
is the target of the loopback message. This address can be entered
in either of the following formats: xx-xx-xx-xx-xx-xx or
xxxxxxxxxxxx
domain-name – Domain name. (Range: 1-43 alphanumeric
characters)
ma-name – Maintenance association name. (Range: 1-45
alphanumeric characters)
transmit-count – The number of times the loopback message is
sent. (Range: 1-100)
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.
Egr. 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.
Relay Relay action:
FDB – Target address found in forwarding database.
MPDB – Target address found in the maintenance point database.
HIT – Target located on this device.
