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

[Tantsura, Jeff]

Alexander,

Have you tried:
channel-group 1 mode on 
and disable negotiation on Juniper side?

Also

CCO:

When a group is first created, all ports follow the parameters set for the
first port to be added to the group. If you change the configuration of one
of these parameters, you must also make the changes to all ports in the
group:

-Allowed-VLAN list

-Spanning-tree path cost for each VLAN

-Spanning-tree port priority for each VLAN

-Spanning-tree Port Fast setting

Folks,

I have a problem that did cost me one half of this night -
and I hope anyone can shed some light on it. I tried to
bring up a Portchannel to a newly- deployed 3750 and it did
not work. The two GE-PICs in the Juniper have the latest
revision of their firmware, and it was a E-FPC, so that was
taken care of already.

When I configured the Portchannel on the 3750 the two trunk
ports were suspended due to LACP not being active on the
other side -- which is correct as I did not change the
configuration there yet.

I put the usual config for the ae0 on the Juniper, with lacp
active, and on the 3750 that comes down to 'channel-proto lacp'
and 'channel-group 1 mode active'. After all interface and
Po1 were in sync the Aggregated Ethernet (/Portchannel) did
not come up. All shut/no shut here and there did not help.

Anyone here has any ideas/clues on this? JunOS as well as
IOS are exactly the same on several other boxes, also M40,
also 12-port 3750. IOS was c3750-i9k91-tar.122-25.SEA.tar.

Please, any clues on that one? Would the same thing work
'by accident' if I leave out LACP? I have to admit I am not
aware of all implicitations on that, and not yet fully awake
again (sort of).

Thanks a bunch,
Alexander
