[c-nsp] Cisco 3012 IBM Blade Switch Configurations?

[McLean Pickett]

Chris -

The CIGESM's are expensive and have limited feature support based on the way
they are deployed in the chassis (you can't channel the NICs on the blades).
They are additional devices to support and every time the server guys reboot
the chassis spanning tree is impacted.

Go with the pass-through modules and connect the blade NIC's to an external
switch.

Not sure if the CIGESMs in the eServer BladeCenters are the same  
thing, but with those, connectivity between two modules in the same  
chassis is provided by one of the internal mgmt interfaces.  It's  
Gi0/15 in my case.  I think there's some stuff you have to tweak in  
the MM gui, but it should be pretty easy to find, although I can't  
recall off the top of my head.
