Management IP addresses of controllers the LAP remembers previously. Where?

Management IP addresses of controllers the LAP remembers previously

Where is the previously management IP address of controllers saved by the AP's system? NVRAM? I issue dir nvram: commands and observe that in that NVRAM there are 3 files: startup_config, running-config and private-config. Which one it is?

Thanks

[Scott Fella]

Yes... in NVRAM.  If your ap is lightewieght, then you can issue the following to clear all of the nvram.

config t

Entered the username and password

debug capwap console cli

erase /all nvram:

[confirm]

undebug all

reload

[confirm]

[Totardo Tobing]

Why I never reach the 'conf t'. What is the problem? This access point is lighweight: cisco AIR-LAP1131AG-A-K9 and the IOS is c1130-k9w8-mx.124-13d.JA.

Does this mean I can't go any further than privilege mode in lightweight access point?

[Scott Fella]

Here is an output from a 1142 that is lightweight.  I would delete all in the nvram to clear the AP

AIR-LAP1142N-A-K9#dir nvram:

Directory of nvram:/

   30  -rw-           0                      startup-config

   31  ----           0                      private-config

    1  ----        4100                      lwapp_ap.cfg

    6  ----         528                      lwapp_ap_tlv.cfg

    7  ----          23                      persistent-data

Can you just run the debug capwap console cli?

[Scott Fella · Accepted solution]

It depends on how you access the AP... so just run these commands:

debug capwap console cli

erase /all nvram:

[confirm]

undebug all

reload

[confirm]

[Totardo Tobing]

We only have this options sir:

AP0007.0e5f.ef30#debug capwap ?

  am      KAM-AP debug

  client  CAPWAP Client Debug Options

  ids     WIDS debug

  mcast   CAPWAP MCAST Debug Options

  mfp     CAPWAP MFP Debug Options

  reap    CAPWAP REAP Debug Options

  rm      CAPWAP RM Debug Options

there is no debug capwap console cli. Why it different? This LAP too..

[Scott Fella]

Don't do a '?'.... its a hidden command:)

[Totardo Tobing]

Yess!!! Sure!! It's hidden. How you know it Scott??

Ah You are a hero!! Thanks men.

But, any hidden command again that useful for us to troubleshoot, Scott?

Btw, thanks again Scott. I can clear it now, and ready to rejoinning the Access Point again. Here's our:

================================

AP0007.0e5f.ef30#debug capwap console cli

This command is meant only for debugging/troubleshooting

Any configuration change may result in different

behavior from centralized configuration.

CAPWAP console CLI allow/disallow debugging is on

AP0007.0e5f.ef30#

AP0007.0e5f.ef30#

AP0007.0e5f.ef30#erase /all nvram:

Erasing the nvram filesystem will remove all files! Continue? [confirm]

[OK]

Erase of nvram: complete

==================================================

and after that reload the access point as you taught.

Thankyou.

[Scott Fella]

That command allows you to also allow you to issue config t, but again, be careful and some commands will get overwritten by the wlc. That is how I make sure my APs are clear of any old config. There is a good Cisco book on troubleshooting wireless lans and it does go over the debugs and how to read the debugs.

Great!! Another great commands!!!

I can enter 'config t'!! But, what can I do from this config-mode? Do this means now I can configure this LAP like an autonomous? Because I see that I configure almost any command in autonomous access point.

[Totardo Tobing]

Ah pardon me, I'm so foolish. Just ask and ask. Okay I will improvise. Thanks Scott, this is really helpful.

[Scott Fella]

You can't configure that ap as autonomous. It allows you to do some commands, but in the end, the configuration is done by the wlc. You can define the syslog server though.

[Totardo Tobing]

Ah Okay. I note that. This command can be used to define syslog server. Thank you Scott.

[Scott Fella]

No problem.
