[c-nsp] Strange trunk behavior

[Sascha Pollok]

Hello Ghassan,

just to make sure: is the encapsulation set to 802.1q on the ME3400? Afaik 
it does still support ISL. You might want to share "sh int x/x capa" on 
both sides and maybe also the interface's config. Also, is there anything
in between the switches that could cause some interference or are they
directly connected back-to-back?

Cheers
Sascha
