老了一点,其中的部分命令可能已经失效了!参考一下。
csim
show interface switching
show ip ospf statistics
debug ip ospf monitor
ttcp
if-con
no snmp-server sparse-tables
who
show region
ps -c
quit
test aaa group radius
list of more and more undocumented commands
If you know more undocumented IOS commands for this collection, please send me a e-mail.


--------------------------------------------------------------------------------
With the command csim you can emulate a voice call. It′s like sombody calls the specified number. Usefull, if you don′t have physically access to telephone:
Sucessfull call:

wg1r1#csim start 089150
csim: called number = 089150, loop count = 1 ping count = 0
csim err csimDisconnected recvd DISC cid(21)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0

Call to a not defined number:

wg1r1#csim start 089151
csim: called number = 089151, loop count = 1 ping count = 0

csim err:csim_do_test Error peer not found


--------------------------------------------------------------------------------
With show interface switching you can see in detail, which protocols are process, fast or elsewhere switched. It′s helpfull for traffic engineering:
wg1r1#sh interfaces switching
Ethernet0/0
Throttle count 0
Drops RP 0 SP 0
SPD Flushes Fast 0 SSE 0
SPD Aggress Fast 0
SPD Priority Inputs 5700 Drops 0

--------------------------------------------------------------------------------
With show ip ospf statistics you get detail informations about OSPF SPF. You can see the reasons for SPF and the calculation times:
London#show ip ospf statistic
Area 0: SPF algorithm executed 15 times

SPF calculation time

00:01:21 24 0 0 4 0 0 36 R,


--------------------------------------------------------------------------------
With debug ip ospf monitor you can monitor the OSPF SPF.
London#deb ip ospf monitor

OSPF spf monitoring debugging is on

router> ps -c

Will list the process on the router in a "better" way then show process.

Many thanks for this command goes to Thomas Surber.


--------------------------------------------------------------------------------

leaving a telnet session: normally with "exit" or "ex".
do this very fast with "q" (quit)

Many thanks for this command goes to Peter Schmid.


--------------------------------------------------------------------------------

test aaa group radius toto titi

To test radius on one router.

Many thanks for this command goes to Serge Baikof.
