Using the Command Line Interface

beacon-interval

This command configures the rate at which beacon signals are transmitted from
the access point.

Syntax

beacon-interval

interval>

interval

- The rate for transmitting beacon signals.

(Range: 20-1000 milliseconds)

Default Setting

100

Command Mode

Interface Configuration (Wireless)

Command Usage

The beacon signals allow wireless clients to maintain contact with the access
point. They may also carry power-management information.

Example

dtim-period

This command configures the rate at which stations in sleep mode must wake up
to receive broadcast/multicast transmissions.

Syntax

dtim-period
