Hi,

it does not support negotiation protocols, such as PAGP or LACP, so you must configure the etherchannel manually in the HP Comware switch to match the configuration of the router.

Best Regards,

Hi,

Like yourself I have been hunting to find out if a 3945 (ISRG2) can support LACP.
It seems that this family of routers and ISR-G1s can only support MANUAL Ether-channelling.

I cant find a similar paper for ISR-G2s.
