How about mixing 3550's and 3560's on each side?
-----------------------------------------------------------
The basic theory of etherchannel:
there are 2 protocol standard in etherchannel - PAgP and LACP.
PAGP is cisco properietary , therefore if you configure switch to use PAgP,
both switch must be Cisco make. No matter what model i.e. 3550 or 3660 or
65xx. All works okay.
LACP is a Ieee802.3ad standard. Therefore any make any vendor/module doesn't
matter.
So you can plugin one end Cisco switch and other end Cisco.
Cisco----4port trunk--------HP-sw
I have personally tested it and it is working in production environment.
