Boerland from Netherlands maintains a raw list of IOS commands, most of
them unknown:
Lots of undocumented IOS commands !
Real output of unknown OSPF commands, which you can see here.
I plan to add more and more of these samples and show them here.
Undocumented CatOS Command for WS-X6608-T1
(or E1)
Wanna know some undocumented CAT
commands ?
Wanna know about the secret engineer
mode in a Catalyst 5K ?
(I recently heard it works in a Cat6K also ! And it
works with Engine III as well)
The following are brandnew undocumented IOS
commands just discovered.
Some (or most) are IOS-version-dependent of course.
Please don't mail to ask me what they do.
If I would know or when I know I'll put it on this
site.
If you do know more about this commands please let
me know. Thanks.
set dummy
Selective Packet Drop (spd) is now documented on
CCO:
show ip spd
Sample output:
Router# sh ip spd
Current mode: normal.
Queue min/max thresholds: 73/74, Headroom: 100
IP normal queue: 1, priority queue: 0.
SPD special drop mode: none
The following info updates (or adds to) some
comments on Bert Boerlands's site:
The "test appletalk" command appeared already in
some 11.2.x and 11.3.x
releases
The filenames in cd system:/vfiles are NOT:
tmstats.ascii
tmstast.binary
CORRECT is:
tmstats_ascii
tmstast_binary
Here is a new one: this is closely held secret at CISCO:
There is a quiet recall on some catalyst gear that have the EARL 1 chip NFFC
and a data rate that exceeds 80MBS accross the backplane that causes the ECB
to reset often. Test to see if your catalyst is having this problem: (users
usually report slowness.)
cat5000#> sh banff-reset
will display the number of time it has reset since last power on, a number
of 1 for each ECB is normal
number in the hundreds ar thousands means you need to call CISCO for the
replacement boards.
For those which have tried the "no service password-recovery", a very dangerous
thing to do BTW, click here for some more info.
Undocumented CatOS Command for WS-X6608-T1 (or E1)
(thanks to Martin Gagnon, Canada)
tracy_start [MOD] [PORT]
tracy_close [MOD] [PORT] (to stop the output...)
In fact, you will got the same output as using DickTracy win32 tool
