beacon-interval

Function

The beacon-interval command sets the interval for sending Beacon frames.

The undo beacon-interval restores the default interval for sending Beacon frames.

By default, the interval for sending Beacon frames is 100 TUs.

Format

Usage Guidelines

An AP broadcasts Beacon frames at intervals to notify STAs of an existing 802.11 network. After receiving a Beacon frame, a STA can modify parameters used to connect to the 802.11 network.

A long interval for sending Beacon frames lengthens the dormancy time of STAs, while a short interval for sending Beacon frames increases air interface costs. Therefore, you are advised to set the interval for sending Beacon frames for an AP based on the VAP quantity. The following intervals for sending Beacon frames are recommended for APs with different VAP quantities on a single radio:

No more than 4 VAPs: about 100 TUs
5 to 8 VAPs: about 200 TUs
9 to 12 VAPs: about 300 TUs
13 to 16 VAPs: about 400 TUs

Ensure that the air scan interval meets the following condition: scan-interval ≥ beacon-interval + 100 ms

Example

# Set the interval for sending Beacon frames to 200 TUs in the 2G radio profile default.
