Configuring Load Rebalancing for 802.3ad Link Aggregation Groups

You can configure the parameters that the system uses to rebalance the links in a
LAG. You can also configure the system to dynamically rebalance the links in the
LAG.
Tasks to configure load rebalancing are:
Configuring Load Rebalancing Parameters
To configure load–rebalancing parameters:
1.
2.
Table 20 on page 193 describes the load balancing algorithm parameters that you
can configure.

Table 20: Load Balancing Algorithm Parameters

Configuring Load–Rebalancing Parameters on page 193
Configuring the System to Dynamically Rebalance the LAG on page 195
Specify the LAG interface.
host1(config)#interface lag lg1
Configure parameters that guide the system to rebalance.
host1(config-if)#load-rebalance period 120 start-threshold 20 percent
stop-threshold 100 percent maximum-improvement 300
This example specifies that the system rebalance within 120 seconds, can accept
imbalance in the LAG in the range 20–100 percent, and can move 300 subscribers
to other ports during that time.
Keyword Description
period Specifies the time period for rebalancing. For example, a period of 120
specifies that rebalancing occurs once every 2 minutes.
