Configuring Load Balance of Link Aggregation
This section describes how to configure link aggregation with load balance settings.
Beginning in privileged EXEC mode, follow these steps to configure link aggregation with load
balance settings:
Command
Step 1
configure
Step 2
interface interface-id
Step 3
load-balance
<dst-ip/dst-mac/src-dst-ip/src-dst-mac/
src-ip/src-mac>
Step 4
exit
Step 5
exit
Step 6
show port-channel all
To set the load balance setting of a port-channel group, use load-balance interface
configuration command. To display port-channel group, use show port-channel all
privileged EXEC command.
In this example, a port-channel group downlink-lag1 is set to use source IP and
destination IP for its load balance setting.
(BX900-CB1)#configure
(BX900-CB1)(Config)#port-channel downlink-lag1
Interface BX900-CB1/1/3 created for port-channel downlink-lag1
(BX900-CB1)(Config)#interface BX900-CB1/1/3
(BX900-CB1)(Interface BX900-CB1/1/3)#load-balance src-dst-ip
(BX900-CB1)(Interface BX900-CB1/1/3)#exit
(BX900-CB1)(Config)#exit
(BX900-CB1)#show port-channel all
