Hello Sunish,

LACP is standard based 802.3ad so it should be your best choice as described here:

http://subversity.net/link-aggregation-on-cisco-catalysts-and-found

if the C3750 is a stack you can form your bundle using ports taken from different switch members.

for trunking you need to use standard based 802.1Q

int gix/y

switchport

switchport trunk enc dot1q

switchport mode trunk

switchport trunk allowed vlan x,y,z

shut

you need to prepare all the ports before then you can add

verify with sh etherchannel summary and use a free not used group number

int gix/y

channel-group k mode active

then you can activate all the ports using interface range if you want to make a bundle that also acts as a trunk.

in interface range you can give no sh

follow the above link for configuration on the foundry side

Hope to help

Giuseppe
