We have four WiSM's with about 750 APs and 1500-2000 concurrent users running
4.2.62.0 code. We have always averaged two percent or less with occasional
spikes to 15%.

Subject: [WIRELESS-LAN] Cisco Wisms CPU
Hi All,
A quick question for those out there with WISMs... 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
