The mode of VLAN Pool

Usage Scenario

Since WLANs provide flexible access modes, STAs may connect to the same WLAN at the office entrance or stadium entrance, and then roam to different APs. If each SSID has only one service VLAN to deliver wireless access to STAs, IP address resources may become insufficient in areas where many STAs access the WLAN, and IP addresses in the other areas are wasted.

After a VLAN pool is created, add multiple VLANs to the VLAN pool and configure the VLANs as service VLANs. In this way, an SSID can use multiple service VLANs to provide wireless access services. STAs are dynamically assigned to VLANs in the VLAN pool, which reduces the number of STAs in each VLAN and also the size of the broadcast domain. Additionally, IP addresses are evenly allocated, preventing IP address waste.

You can also apply the VLAN pool to a user group to plan network segments by user role.

Follow-up Procedure

Run the vlan command to add VLANs to a VLAN pool.

Precautions

After a VLAN pool is configured to provide service VLANs, VLANs in the VLAN pool cannot be deleted. To delete the VLAN pool, cancel the service VLAN configuration of the VLAN pool.
