Chapter 33 Configuring EtherChannels
Configuring EtherChannels
Beginning in privileged EXEC mode, follow these steps to assign a Layer 2 Ethernet port to a Layer 2
EtherChannel. This procedure is required.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify a physical port, and enter interface configuration mode.
Valid interfaces include physical ports.
For a PAgP EtherChannel, you can configure up to eight ports of
the same type and speed for the same group.
For a LACP EtherChannel, you can configure up to 16 Ethernet
ports of the same type. Up to eight ports can be active, and up to
eight ports can be in standby mode. If your switch is part of a
switch stack, the 16 ports in the LACP EtherChannel must be on
the same switch.
Step 3
switchport mode {access | trunk}
switchport access vlan vlan-id
Assign all ports as static-access ports in the same VLAN, or
configure them as trunks.
If you configure the port as a static-access port, assign it to only
one VLAN. The range is 1 to 4094.
