Usage Guidelines

Usage Scenario

A STA listens on the Beacon frames that an AP periodically sends in each channel to obtain AP information. The STA can obtain SSIDs from Beacon frames that contain the SSIDs.

The STA can actively send a probe frame with a specified SSID, only the AP with the same SSID will respond to the STA. If the STA broadcasts a probe frame without an SSID, only the APs on which SSID hiding in Beacon frames is disabled will respond to the STA.

After the ssid-hide enable command is used, an AP periodically sends Beacon frames that contain empty SSID character strings and does not reply to the broadcast probe requests sent from STAs. The STAs can send probe frames with the AP's SSID to discover the SSID.
After the undo ssid-hide enable command is used, an AP periodically sends Beacon frames that contain valid SSID character strings and replies to the broadcast probe requests sent from STAs. The STAs can send probe frames with the AP's SSID to discover the SSID.

Precautions

If the ssid-hide enable or undo ssid-hide enable command is run in the SSID profile after STAs are associated with an SSID, service interruptions may occur for all online STAs.

Example
