LACP randomly fail between hpe5700 and cisco 6509

[lozair31]

We can attempt to find the last version.

I must plan this update because it's production.

I don't really understand what can cause this behavior. Do you have any idea STP/LACP....

In your firsts posts you talked about set the link between 6500 an HP5700 in etherchannel static mode.

As these 2 switchs are connected directly is there any issue to do nonLACP bonding ?

We always setup LACP as a standard bonding mode but we have ne experience in static bonding mode.

It seems we must be very carreful on static etherchannel to avoid loop.
