DescriptionField
(Exploratory traceroutes) The MAC address of the
interface from which the reply was sent, and the
ingress/egress action, are displayed on the first line.
If the interface name was present in the reply, it is
displayed on the second line.
MAC/Name
Type of relay action performed.
For standard traceroutes, the possible values are:
• Hit—The target MAC address was reached.
• FDB—The target MAC address was found in
the Filtering Database (the MAC learning table
on the switch) and will be forwarded by the
interface.
• MPDB—The target MAC address was found
in the MP Database (the CCM Learning
database on the switch).
In addition, “MEP” is displayed on the second line if
a terminal MEP was reached.
For exploratory traceroutes, the possible values are:
• Hit—The target MAC address was reached.
• FDB—The target MAC address was found in
the Filtering Database and will be forwarded at
this interface.
• Flood—The target MAC address was not found
in the Filtering database, and will be flooded at
this interface.
• Drop—The target MAC address will not be
forwarded at this interface.
