Hi,

Yes, you can actually Etherchannel ports form both Sups together and if the active one fails the stand-by sup will continue forwarding traffic.

Hello,

Just to add to what reza said, this particular setup of ether channel is known as MultiChassis Ether Channel (MEC) on CAT 6500 platforms.

All ports of standby chassis forward data traffic along with active chassis.

Thank you
