Configuring The Physical Interfaces - Cisco 3845 - Security Bundle Router Software Manual

Chapter 28 Configuring EtherChannels
To remove the port-channel, use the no interface port-channel port-channel-number global
configuration command.
This example shows how to create the logical port channel 5 and assign 172.10.20.10 as its IP address:
Switch# configure terminal
Switch(config)# interface port-channel 5
Switch(config-if)# no switchport
Switch(config-if)# ip address 172.10.20.10 255.255.255.0
Switch(config-if)# end

Configuring the Physical Interfaces

Beginning in privileged EXEC mode, follow these steps to assign an Ethernet port to a Layer 3
EtherChannel. This procedure is required.
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 no ip address
Step 4 no switchport
OL-23400-01
Purpose
Enter global configuration mode.
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.
Ensure that there is no IP address assigned to the physical port.
Put the port into Layer 3 mode.
