38 Internet Protocol (IP) Enhancements Release Note
Software Version 2.9.1
C613-10486-00 REV C
enable ip debug
Syntax ENAble IP DEBug={ARP|PACket|ADVertise|UPNP|ALL}
[TIMEOut={NONE|1..2400}]
Description The new timeout parameter specifies the time period, in seconds, for which IP
debugging is enabled. Setting a timeout reduces the risk of overloading the
router or switch and the display with too much debugging information. The
value set by the timeout parameter overrides any previous IP debugging
timeout values, even if they were specified for other debugging options. The
default is the timeout value used the last time that this command was run, or
none.
To change the current timeout value, re-enter the command enable ip
debug={arp|packet|advertise|upnp|all} timeout={none|1..2400}. A value of
none turns the timeout off.
Note that you can also enter the command enable ip debug without specifying
an option on the debug parameter. This starts a different debugging mode, in
which IP stores the header and the reason for rejection of the 40 most recent
incorrectly formatted IP packets. You can then display the stored information
by using the show ip debug command. The new timeout parameter has no
effect when debugging is in this mode.
Examples To display ARP debugging information for the next 25 seconds, use the
command:
enable ip debug=arp timeout=25
To enable all debug options indefinitely, use the command:
enable ip debug=all timeout=none
