[nsp] Catalyst + Netapp

[morph]

Howdy!

Do you have weird experiences with a "NetApp 960" connected to a 550x 
catalyst ?

The problem is about connecting the netapp with a port channel of 2 
ports. When 1 port of the netapp gets down, the catalyst doesn´t see it 
down and it doesn´t takes the port out of the port channel, so the 
catalyst  tries to keep sending traffic to the netapp "ad eternum".
Netapp says this is a recognized bug in the 550x platform, but I haven´t 
found nothing at Cisco.

Any thoughts? :)
