Configure EtherChannel

The following guidelines and restrictions are useful for configuring EtherChannel:

EtherChannel support – All Ethernet interfaces must support EtherChannel with no requirement that interfaces be physically contiguous.

Speed and duplex – Configure all interfaces in an EtherChannel to operate at the same speed and in the same duplex mode.

VLAN match – All interfaces in the EtherChannel bundle must be assigned to the same VLAN or be configured as a trunk (shown in the figure).

Range of VLANs – An EtherChannel supports the same allowed range of VLANs on all the interfaces in a trunking EtherChannel. If the allowed range of VLANs is not the same, the interfaces do not form an EtherChannel, even when they are set to auto or desirable mode.
