Configuration Examples for IEEE 802.3ad Link Bundling
Example: Configuring LACP for Gigabit Interfaces
The following example shows how to configure Gigabit Ethernet ports 0/2 and 0/4into port channel 1 with
LACP parameters.
Device> enable
Device# configure terminal
Device(config)# lacp system-priority 65535
Device(config)# interface port-channel 1
Device(config-if)# lacp max-bundle 1
Device(config-if)# ip address 10.1.1.1 255.255.255.0
Device(config-if)# exit
Device(config)#
Device(config-if)# no ip address
Device(config-if)# lacp port-priority 100
Device(config-if)# channel-group 1 mode passive
Device(config-if)# exit
Device(config)# interface gigabitethernet 0/4
Device(config-if)# no ip address
Device(config-if)# lacp port-priority 200
Device(config-if)# channel-group 1 mode passive
Device(config-if)# end
Example Associating a Channel Group with a Port Channel
This example shows how to configure channel group number 5 and include it in the channel group.
Device1# configure terminal
Enter configuration commands, one per line.
Device1(config)# interface port 5

Configuring IEEE 802.3ad Link Bundling
Description
Number of packets stored in main memory when the
output queue is full; swapping buffers to main
memory prevents packets from being dropped when
output is congested. The number is high when traffic
is bursty.
End with CNTL/Z.
