Example of Debugging Command

This section introduces using and information of debugging command

through example.

For the environment and configuration, please refer to UDLD application

example one.

1. Port 0/1 receives the processing of one packet via

debug udld

port 0/0

.

Enable the command

debug udld port 0/0 1

SwitchA#

debug udld port 0/0 1

Displayed Result

Analysis

UDLD parse: Port 0/0 St:udld_St_Echo protEv:udld_Ev_EchoMsg
Len:92 Rlt:UDLD_RLT_INDTRMINT
UDLD fsm: Port 0/1 Event:udld_Ev_EchoMsg Len:92 [Pos
F:udld_iEchoRcvProc L:855]

Port 0/0 receives
event of
udld_Ev_EchoMsg,
the event further
comprises an echo
data package with
length about 92.
When the port
receives the event,
the Port 0/0 is under
status of
udld_St_Echo. The
single communication
status in the current
is unknown.

Enable the command

debug udld port 0/0

receive

to check the

contents of the UDLD packet received by port 0/0.
