FW: [c-nsp] Cisco Gigabit Ethernet Switch Module (CGESM)fortheHPBladeSystem

[christian.macnevin at uk.bnpparibas.com]

It now seems that our guys testing the CGESMs with the most current 
feature set are seeing that they don't seem to permit
manual config of 100/full (and subsequently negotiate down to half in many 
cases) and they're seeing nasty buffer overruns.

Support doesn't seem to be picking us up here, either.

I assume there's no HP people on this list, but why on earth did they 
chose a 2900 to repackage? These blade enclosures
may be used in less than critical arenas by some ISPs, but if I told you 
the projected number we're looking at over the next year,
and the seriousness of the calculations going on, you'd think it was a 
joke they hadn't taken things a bit more seriously.

Do you run "spanning-tree etherchannel guard misconfig" on your core
when you use etherchannel links? Does it work as advertised?
