On a somewhat related note, does anyone have the SNMP OIDs to monitor the CPU load on the WiSM?

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.

What level of CPU usage are you experiencing (with how many users)? A bit of background... We have two wism blades (4 wisms) and since we purchased them in about april'07 they were running at about 35%, rising to 50% at peak times, with frequent spikes up to about 90%. The spikes were worrying, but the average seemed ok, and as they did this from day one I was under the impression this was the norm. Recently, we upgraded to the 4.2.x.y stream from 4.1. As has been covered in other recent posts, 4.2 has some outstanding issues (more than others anyway) and things became unstable... so we decided to go back to 4.1.85.0 (TAC hasn't provided us with any solutions for 4.2 issues). We had a backup of our previous 4.1 config, but I chose not to use it and start again from scratch (a few things had changed, so either way involved work) Since the reversion to 4.1.85.0, our cpu usage now averages 2% and peaks at 6% at peak times (220 waps, ~350 users). [4.1.85.0, 12.2(18)SXF7] Thanks, James -- James J J Hooper Network Specialist Information Services University of Bristol http://www.wireless.bristol.ac.uk -- ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
