You can create an EtherChannel on a switch, on a single switch in the stack, or on multiple switches in the stack (known as cross-stack EtherChannel).
All ports in an EtherChannel must be assigned to the same VLAN or they must be configured as trunk ports.
When the ports in an EtherChannel are configured as trunk ports, all the ports must be configured with the same mode (either Inter-Switch Link [ISL] or IEEE 802.1Q).
Port Aggregation Protocol (PAgP) can be enabled only in single-switch EtherChannel configurations; PAgP cannnot be enabled on cross-stack EtherChannels.
