Configuring Auto Shutdown Settings

Auto shutdown provides a mechanism to regulate the availability of a WLAN based on time. WLANs can be enabled or disabled depending on the day of the week and time of day.

A WLAN can be made available during a particular time of the day to prevent misuse and reduce the vulnerability of the wireless network. WLANs can be disabled when there are no users on the network, such as after hours or during the weekends/holidays. This enables the network administrator to have more time to manage the network as the mundane task of shutting down/staring up a WLAN is automated.

You can also use the Auto Shutdown screen to configure network parameters, which if not met, can force the WLAN to shut down. These parameters are:

• Shutdown on Mesh Point Loss – If an access point is a member in a meshed network and its connection to the mesh is lost, then all WLANs on the access point that have this option enabled are shut down.
• Shutdown on Primary Port Link Loss – When there is a loss of link on the primary wired link on the access point, all the WLANs on the access point that have this option enabled are shut down.
• Shutdown on Critical Resource Down – If critical resource monitoring is enabled on the access point and one or all of the monitored critical resource goes down, the all WLANs on the access point that have this option enabled are shut down.
• Shutdown on Unadoption – If the access point is unadopted from its wireless controller, then all WLANs on the access point that have this option enabled are shut down.

To configure auto shutdown for a WLAN:

1. Select Configuration → Wireless → Wireless LANs to display a high-level display of the existing WLANs.
2. Click Add to create an additional WLAN, or click Edit to modify the properties of an existing WLAN.
3. Select Auto Shutdown.
