I have four WISM's in two 6509 chassis running 188.8.131.52 and am going to do an upgrade on them in the next couple of days. I know there are several versions that are not the best at keeping the WISM's up, and I wanted to know what version some of you are running successfully. The issues I have with the current code is the enability to keep them running for more than 30 days at a time. Just about every thirty days one of the four will go down, even though the core says its still up.
I have ran into this issue only on 1 controller on 1 of my 5 Wism's. There are 4 listed bugs on this(CSCsh35306,CSCsh48977, CSCsh50527, CSCsh50966) All dealing with ARP issues that make the controller inaccessable from the IP network. The only access you have is VIA the service port from the 6500 session command.
Version 184.108.40.206 is the latest version that will be public very soon (maybe a week or so) & it addressed a problem I had with roaming between controllers with the client getting disassociated, and then receiving a new IP address upon re-associating to the new controller. You would need to open a TAC case to get the special access to get the version as of now, but I would suggest doing so. Also to let you know there will be a new version 4.1 comming around the May time frame that will be adding many new fetures. Contact me off line if you would like to discuss further.
I spoke with Tony who posted above and he told me that 220.127.116.11 was available from Cisco TAC if issues persist in 18.104.22.168. I am going to launch a call to TAC to see if I can get this and make it happen. He also stated that 4.1.0 is going to be available in about 2 more months and he is in the process of beta testing it for Cisco. I will be looking forward to getting that asap.
My final question involves something that TAC told me. I am running 12.2(8)SXF4 on the core 6509's and I was told by TAC that I should upgrade the cores to 12.2(8)SXF6 before installing the newer code on the WiSM's. I don't know if this is true and just wanted to see if anyone has moved to 4.0 code on the WiSM's making the controllers more reliable without upgrading the core code. This is something I don't have the option to do since these are mission critical 6509's and upgrading could effect other things on the network.
