Wireless Load Balancing

This chapter shows you how to configure wireless load balancing.

13.1 Wireless Load Balancing Overview

Wireless load balancing is the process whereby you limit the number of connections allowed on an wireless access point (AP) or you limit the amount of wireless traffic transmitted and received on it. Because there is a hard upper limit on the AP’s wireless bandwidth, this can be a crucial function in areas crowded with wireless users. Rather than let every user connect and subsequently dilute the available bandwidth to the point where each connecting device receives a meager trickle, the load balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.

13.2 Wireless Load Balancing Commands

The following table describes the commands available for wireless load balancing. You must use the configure terminal command to enter the configuration mode before you can use these commands.

Table 46 Command Summary: Load Balancing

COMMAND

DESCRIPTION

[no] load-balancing kickout

Enables an overloaded AP to disconnect (“kick”) idle

 

clients or clients with noticeably weak connections.

load-balancing mode {station traffic}

Enables load balancing based on either number of

 

stations (also known as wireless clients) or wireless traffic

 

on an AP.

 

 

load-balancing max sta <1..127>

If load balancing by the number of stations/wireless

 

clients, this sets the maximum number of devices allowed

 

to connect to a load-balanced AP.

 

 

load-balancing traffic level {high low

If load balancing by traffic threshold, this sets the traffic

medium}

threshold level.

load-balancing alpha <1..255>

Sets the load balancing alpha value.

 

When the AP is balanced, then this setting delays a

 

client’s association with it by this number of seconds.

 

Note: This parameter has been optimized for

 

the NXC and should not be changed

 

unless you have been specifically

 

directed to do so by ZyXEL support.
