I don't really understand what is downstream channels....

[peyrache]

ethernet port of server side inside HPE Chassis

what is the verion of CBS ?

[lozair31]

It's a :12.2(50) version as shown below :

Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 24 WS-CBS3032-DEL-F 12.2(50)SE3 CBS31X0-UNIVERSAL-M  

[peyrache]

could you update to at least most recent version please ?

[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.

regards

latest is something like 15.X

there are some issue around lactp/stp fixed

[lozair31]
