Cisco Bug: CSCvi61401 - WLC remote access failing after upgrade
Jun 21, 2018
- Cisco 5500 Series Wireless Controllers
Known Affected Releases
Symptom: - Upgrading WLC from 188.8.131.52 to 184.108.40.206 or even 220.127.116.11, but after installing the new code and rebooting the WLC, the controller is not accessible anymore in the new code (only over console and Service Port). - APs join (clients even connect), but can't SSH/TELNET or HTTP/HTTPS into the WLC. - We can ping the WLC from the network, but the WLC can't ping anything if we source the ping from the WLC itself, not even the gateway (learnt in WLC ARP table). - If we configure the WLC to boot from old image 18.104.22.168, issue goes away. - If we configure the WLC to boot from new image (22.214.171.124 or 126.96.36.199) again, issue comes back. Conditions: - Running specific configuration in the WLC and upgrading from old code 8.0 to 188.8.131.52 or even 184.108.40.206.
