Configuring Layer 3 EtherChannels Follow these steps to assign an Ethernet port to a Layer 3 EtherChannel. This procedure is required. Procedure Configuring EtherChannels Configuring Layer 3 EtherChannels Command or Action Purpose to a channel group, and to use the port for transmission. • active—Enables LACP only if a LACP device is detected. It places the port into an active negotiating state in which the port starts negotiations with other ports by sending LACP packets. • passive —Enables LACP on the port and places it into a passive negotiating state in which the port responds to LACP packets that it receives, but does not start LACP packet negotiation. Step 7 end Example:
Device(config-if)# end Returns to privileged EXEC mode. Command or Action Purpose Step 1 enable Example: Device> enable Enables privileged EXEC mode. Enter your password if prompted. Step 2 configure terminal Example: Device# configure terminal Enters global configuration mode. Step 3 interface interface-id Example: Device(config)# interface gigabitethernet 1/0/2 Specifies a physical port, and enters 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. Configuring EtherChannels 15
