I have seen strange problem in WiSM, while configuring as service vlan, I could see the status of one of the service vlan's as Oper-Up. Second one is mentioned as -- , whereas I could access both wism by means of html. Through CLI i could access only one WisM.
Apart from that, I could see in log files lost hearbeat with supervisor. Is this log related with the missing service vlan's . How can I solve this issue? Will it be due to WiSM/Core Switch IOS incompatibility?
1. Could you please advise regarding strange issue which happens on my wism
When I type show wism module, I see one of the controller is mentioned with service vlan ip and controller ip and status as 'Oper-Up' , whereas second wism controller does show any ip and is mentioned as -- with status mentioned as 'Service-Up'. But remotely i can access both controllers through WiSM.
Why does it come so? I am having controller firmware version 5.0. How can I solve this issue.
2. Secondly as I have heard from other users that 5.0 is buggy firmware, will I lose my configuration if i upgrade firmware to 5.2/6.0
