VLAN Configuration
This chapter explains the following topics:
l VLAN Pooling
l Uplink VLAN Monitoring and Detection on Upstream Devices
VLAN configuration is required for networks with more devices and broadcast traffic on a WLAN SSID or wired
profile. Based on the network type and its requirements, you can configure the VLANs for a WLAN SSID or
wired port profile.
For more information on VLANconfiguration for a WLANSSID and wired port profile, see Configuring VLAN
Settings for a WLAN SSID Profile on page 83 and Configuring VLAN for a Wired Profile on page 105,
respectively.
VLAN Pooling
In a single W-IAP cluster, a large number of clients can be assigned to the same VLAN. Using the same VLAN for
multiple clients can lead to a high level of broadcasts in the same subnet. To manage the broadcast traffic, you
can partition the network into different subnets and use L3-mobility between those subnets when clients
roam. However, if a large number of clients need to be in the same subnet, you can configure VLAN pooling, in
which each client is randomly assigned a VLAN from a pool of VLANs on the same SSID. Thus, VLAN pooling
allows automatic partitioning of a single broadcast domain of clients into multiple VLANs.
Uplink VLAN Monitoring and Detection on Upstream Devices
If a client connects to an SSID or a wired interface with VLAN that is not allowed on the upstream device, the
client will not be assigned an IP address and thus cannot connect to the Internet. In such scenario, the Instant
UI now displays the following alert message:

To resolve this issue, ensure that there is no mismatch in the VLAN configuration.
