WCSs (5.0.148) lose Terminal, Webfrontend and Web Auth


3xWCS 4404 with 5.0.148 and WCS 5.0.56.

After serveral days, I were not able to connect to the telnet, SSH and webfrontend interfaces on all controllers. I tried management and service-port IPs. But I get ping responses from the interfaces and the Wireless LANs are also working, except the Web Authentication, which is now configured to relay the user to a special url.

In the release notes ( was a caveat (CSCsi30541), but it occurs when you create a new dynamic interface, which I didn't.

The controllers respond to the WCS, so I were able to reboot them via the WCS. After that the situation is normal, until the next time.

Three weeks ago, I installed 5.0 on one of the three WCS. One week ago, I installed it on the other two. This problem occurs on the first WLC for the second time, so I assume, it can happen again.

Any ideas what could be the reason?

Re: WCSs (5.0.148) lose Terminal, Webfrontend and Web Auth

It is a bug in 5.0... The controller will only respond to snmp. The workaround is to reboot. This is a bug if you are using WebAuth. i would open a TAC case to see if they have a work around as of yet, which most likely will be a ER.
