Description
The bidirectional state of the link. An unknown state
appears if the link is down or if it is connected to an
UDLD-incapable device. A bidirectional state appears
if the link is a normal two-way connection to a
UDLD-capable device. All other values mean
miswiring.
The current phase of the UDLD state machine. For a
normal bidirectional link, the state machine is most
often in the Advertisement phase.
How often advertisement messages are sent from the
local device. Measured in seconds.
The time period, in seconds, that UDLD waits for
echoes from a neighbor device during the detection
window.
Information from the first cache entry, which contains
a copy of echo information received from the
neighbor.
The amount of time in seconds remaining before this
cache entry is aged out.
The neighbor device identification.
The neighbor's current state. If both the local and
neighbor devices are running UDLD normally, the
neighbor state and local state should be bidirectional.
If the link is down or the neighbor is not
UDLD-capable, no cache entries appear.
The device name or the system serial number of the
neighbor. The system serial number appears if the
device name is not set or is set to the default (Switch).
The neighbor port ID enabled for UDLD.
The device name of the neighbors' neighbor from
which the echo originated.
The port number ID of the neighbor from which the
echo originated.
The rate, in seconds, at which the neighbor is sending
advertisement messages.
