[j-nsp] portchannel 3750 <-> Juniper M40

[Alexander Koch]

Folks,

following up on my own email... I found the problem:

Whenever I say 'encap vlan-ccc' on the port the ae0 goes
down. This is fixed in 7.1R1 and later. *sigh*

So when your AE is not up, try changing the encap and
if then comes up you know what it is...

We need to upgrade... ;-\

Regards,
Alexander
