But- we keep ALL APs, WiSMs, WCS, and loc servers in a private management VLAN that is heavily protected. Not sure if this has a bearing. This has always been the case (low CPU), across multiple code versions. That being said- we have had just about every other problem associated with the WiSMs and or WCS that you can imagine. Has been challenging, to say the least. Lee H.

Re: [WIRELESS-LAN] Cisco Wisms CPU
We have two CAT6506s, one with a single WiSM (our backup platform) and the second with three WiSMs. The first CAT6506/single Wism has no users and is only used to test new code levels and act as a set of spares for the other box (soon to be several more). The WiSM on this box is running 4.0.206.0. The second CAT6505/three WiSMs supports what little wireless we have moved to the lightweight stuff -- 319 LWAPPs with 300-400 users so far. The WiSMs on this box are running 4.0.206.0 4.0.219.0. I will move them all up to 4.1 (maybe 4.2) at the end of the semester so I have some breathing room to fight problems. The first/almost idle CAT6506 shows a CPU utilization of 0-1% all the time. The second CAT6506 shows an average utilization of 0-1% with peaks of 4%. Not much difference between the two. -jcw To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU From: James J J Hooper [EMAIL PROTECTED] Subject: [WIRELESS-LAN] Cisco Wisms CPU Date: Wed, 13 Feb 2008 21:10:38 + Reply-To: The EDUCAUSE Wireless Issues Constituent Group Listserv WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Hi All, A quick question for those out there with WISMs...
