Hello Saravanan

trying to find rogue on wire using rldp technique but unable to find so far. how long does it take the trigger to detect, using linksys ap as rogue. just like the doc mentioned having similar setup. enabled those rldp debugs but no glimpse of the wlc finding rogue on wire.

Thanks

Hi Robert, what's the wlc code, AP model used, if possible share the debug output.

Re: Ask the Experts: Configuring, Troubleshooting and Monitoring

unsure if debug not showing anything or getting debug output with no reference to find rogue on wire.

be sure to run this on wlc.

(Cisco Controller) > debug dot11 rldp enable

what's the config on security>> wps>> general>> Rogue Location Discovery Protocol >> drop down. Since you're using local mode ap for rldp, it should be selected as "All APs" option. there is no option to say local mode/monitor/mesh/hreap mode AP only. it has to be either monitor for monitor mode only and AllAPs for the rest of the AP modes or it can be disabled.

Re: Ask the Experts: Configuring, Troubleshooting and Monitoring

Well, unfortunatlely there are two bugs with Rogue Detector feature, use the code that has fix on it.

Rogue AP detection on wire fails if radio mac is +/- 1 of ethernet mac

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCub75472

Fixed-In 7.4(100.0).

Cant find rogue on wire, if rogue ap on non native vlan of RD's trunk

Hello,

What am I supposed to do with unclassified rogue AP?

I understand that if they don't look a thread I can mark them as "Friendly External" to no receive more alarms about them. Is it ok?

The problem is what happens  if this external Friendly AP change the SSID for a Managed SSID (an SSID is using our controller). Then, this AP is a threat, but is not longer detected for the controller as Malicious

Is it a bug?

or am I not managing unclassified Rogue correctly?

Thanks

Hi there,

I have installed about 2 days ago one Cisco WCS 2504 and 11 APs. Everything is doing well regarding to WPA authentication. But I have a Radius Server that is also running with some issues on wireless:

- Unless I open network settings and click connect on that config I cannot obtain a valid IP Address;

- Roaming is not working also;

I'm still getting issues regarding Radius;

  - WPA2 Wlan still ok (144Mbit), but dont know when roaming works (how can I know/change these settings?);

  - Radius autenticated with 802.11 Data Encryption on 40 bits Key size connects always at 54Mbps (g) and auto authenticate but dont know when roaming works (how can I know/change these settings?);

  - Radius with 802.11 Data Encryption with none key size, doesnt authenticate connects 144Mbit but doesnt acquire IP Address

TY

Get debug client output when the wireless client seeing the issue.

WLC>debug client

If the client doesn't get an ip then it can't join wlc and success roaming is not possible.

To achieve N datarate using N AP and Client follow this doc:

Configure 802.11n on the WLC

http://www.cisco.com/en/US/products/ps6366/products_tech_note09186a0080a3443f.shtml

802.11n requires AES encryption to be enabled on WLANs used by 802.11n clients. You can use a WLAN with NONE as Layer 2 Security. However, if you configure any Layer 2 security, 802.11n requires WPA2 AES enabled to operate at 11n rates. Ensure that WMM is set to Allowed on the WLAN profile in order to achieve 802.11n rates.
