link aggregation between cisco and 3com switch

[kamhongwong]

i have two cisco 3750 switches which form a stack and a 3com 4226T switch. there are two parallel links connecting them, one end is for 3750 stack and the other end is for 3com switch. In the 3750 side, these two links are connecting to these two 3750 switches respectively. Is it possible to make these two parallel links as a port channel (link aggregation)?

Hi,

You can have a cross-stack etherchannel. However currently only mode "on" is supported for cross stack etherchannels. You cannot use LACP active or passive mode.

This is documented at the link below.
