[c-nsp] transient duplicate ips look like l2 loops

[Christian MacNevin]

Hi
I've seen the odd transient duplicate ip in my logs here and there running
SXF8. I realise this is usually due to
l2 looping but can't see where that would come from in my topology.
Regarding etherchannel configs, what's the recommendation these days? I know
mode desirable on the physical
interface allows better alarming than active but does it also improve your
chances of avoiding l2 loops? Any other
suggestions anyone might have?
Cheers
Christian.
