Enabling the LaCP Feature

Cisco IOS Software does not have the ability to enable or disable LaCP.	feature lacp

Configuring LaCP Active Mode

interface range gigabitethernet 1/1-2 channel-group 1 mode active	interface ethernet 1/1-2 channel-group 1 mode active

Configuring LaCP Passive Mode

interface range gigabitethernet 1/1-2 channel-group 1 mode passive	interface ethernet 1/1-2 channel-group 1 mode passive

Configuring the LaCP Rate Timer (Fast)

interface gigabitethernet 1/1 lacp rate fast	interface ethernet1/1 lacp rate fast

Configuring the LaCP Min/Max Links

interface port-channel 1 port-channel min-links 2 lacp max-bundle 4	interface port-channel 1 lacp min-links 2 lacp max-bundle 4

Configuring Static Mode (no protocol)

interface range gigabitethernet 1/1-2 channel-group 1 mode on	interface ethernet 1/1-2 channel-group 1 mode on

Enabling a Port Channel

interface port-channel 1 no shutdown	interface port-channel 1 no shutdown

Layer-2 Port-Channel Example

interface range gigabitethernet 1/1-2 switchport channel-group 1 mode active interface port-channel 1 no shutdown	interface ethernet 1/1-2 switchport channel-group 1 mode active interface port-channel 1 no shutdown

Layer-3 Port-Channel Example

interface range gigabitethernet 1/1-2 no switchport channel-group 1 mode active interface port-channel 1 ip address 192.168.1.1 255.255.255.0 no shutdown	interface ethernet 1/1-2 no switchport channel-group 1 mode active interface port-channel 1 ip address 192.168.1.1/32 no shutdown

Adding an Interface to an Existing Port-Channel

Cisco IOS Software does not have the force option, so all interface parameters have to be compatible prior to adding the interface to an existing Port-Channel. interface range gigabitethernet 1/3 no switchport channel-group 1 mode active[	interface ethernet 1/3 channel-group 1 force mode active

Configuring the System Load-Balance Algorithm

Configuring the Load-Balance Algorithm per Module

port-channel per-module load-balance port-channel load-balance dst-mac module 1	port-channel load-balance ethernet destination-mac module 1
