EtherChannel on Switches

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).

Restrictions for EtherChannels

• 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.
