Shared memory allocation failed. Internal system error. I am running a WLC 5508 with 7.0.240.0 software version. A am also running a WLC 4402 and a WLC 2125 with this same version and they work just fine. The three WLCs have almost the same UP time (like 180 days) and the outputs of the "show memory mbuf summary" command  are this: (4402) >show memory mbuf summary Maximum number of Mbufs.......................... 4608 Number of Mbufs Free............................. 4601 Number of Mbufs In Use........................... 7 (2125) >show memory mbuf summary Maximum number of Mbufs.......................... 1536 Number of Mbufs Free............................. 1524 Number of Mbufs In Use........................... 12 And finally, the 5508 (5508) >show memory mbuf summary Maximum number of Mbufs.......................... 4608 Number of Mbufs Free............................. 43 Number of Mbufs In Use........................... 4565 Im about to reboot it. ...

Hello Paul. On the Root side, try to change to this parameter: station-role root bridge Also, you could try to change your security settings to use WPA instead of WEP. I hope this helps Regards Karla ... View more

Hello, I has been a while since you posted this issue, but I got it too, so maybe this will help somebody else. I was getting this logs: ____________________________________________________________________________________________________ %DOT11-6-ASSOC: Interface Dot11Radio0, Station XXXX.XXXX.XXXX Associated KEY_MGMT[WPA] Oct 22 17:04:38.370: %DOT11-4-TKIP_MIC_FAILURE_REPORT:Received TKIP Michael MIC failure report from the station XXXX.XXXX.XXXX on the packet (TSC=0x0) encrypted and protected by group key.

Then I made last two successful tests: The firts thing I tried (as a suggestion by googling and TAC) was to use encryption AES (just AES, NOT AES+TKIP) and it worked good. I didnt get desconnected and anything, but the issue was that the AP is going to work with clients that have to use TKIP becuase the wlan profile on the machine cant be changed that easily for different reasons. The last one was to go to another room where there is very few wlan signal noise around (where I was originaly testing the AP, there are a lot of SSIDs flying around). And that was it, using TKIP on this new room work just perfect. I hope this helps Regards Karla ... View more

Segun esta guia, si lo haces por linea de comandos seria algo asi: http://www.cisco.com/en/US/docs/wireless/access_point/12.4_10b_JA/configuration/guide/scg12410b-chap19-wgb-standby.html#wp1036369 >ena #conf t inter dot 0 ssid "nombre de tu red" (sin comillas) exit station-role repeater end cop run start y probar, la verdad nunca lo he intentado.

As fas as I know yes, the controller that still UP will only be able to adopt the # of APs that is allowed by the license it has installed. Doesnt matter if It was part of a mobilty group with a controller that had another 10 APs licence. I was reading thid document, this part may be helpful http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml#licensing The first part talks about having a WLC with a valid AP count license and a backup WLC with a lic to accept APs if the primary WLC goes down. I hope this helps. ... View more

Thanks, Im glad I was thinking right   I'll test it later and tell you how everything went. ... View more
