Configuring a VLAN Pool for Service VLANs
Create a VLAN pool, add VLAN 101 and VLAN 102 to the pool, and set the VLAN
assignment algorithm to hash in the VLAN pool.
[AC]
vlan pool sta-pool
[AC-vlan-pool-sta-pool]
vlan 101 102
[AC-vlan-pool-sta-pool]
assignment hash
[AC-vlan-pool-sta-pool]

In this example, the VLAN assignment algorithm is set to hash (default
value). If the default setting is retained, you do not need to run the
assignment hash
command.
Only VLAN 101 and VLAN 102 are added to the VLAN pool in this
example. You can add multiple VLANs to the VLAN pool using the
same method. You also need to create corresponding VLANIF
interfaces, and configure IP addresses and interface address pools.
WLANs allow STAs to access in flexible modes at different locations. STAs may connect
to the same WLAN in a location (such as the entrance of an office or a stadium), and
roam to a wireless network covered by other APs.
If each SSID has only one service VLAN to deliver wireless access to STAs, IP address
resources may become insufficient in areas with a large number of STAs, and IP
addresses in other areas are wasted. You can configure VLANs in a VLAN pool as
service VLAN of STAs so that one SSID can use multiple service VLANs to provide
wireless access services.
New 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.
Configure an IP address for the DNS server as needed using either of
the following methods:
In the interface address pool scenario, run the
dhcp server dns-list
ip-address &<1-8>
command in the VLANIF interface view.
In the global address pool scenario, run the
dns-list ip-address &<1-
8>
command in the IP address pool view.
