VLAN Operation Issues
Verifying Proper Operation of the VLAN Feature
The correct VLAN configuration can be verified by “pinging” both wired 
and wireless hosts from both sides of the AP device and the network 
switch. Traffic can be “sniffed” on both the wired (Ethernet) and wireless 
(WDS) backbones (if configured). Bridge frames generated by wireless 
clients and viewed on one of the backbones should contain IEEE 802.1Q 
compliant VLAN headers or tags. The VLAN ID in the headers should 
correspond to one of the VLAN User IDs configured for the AP. 
NOTE:
For Dual-radio APs: 
APs with an 11a Upgrade Kit or 802.11b/g Kit 
support up to 16 VLAN/SSID pairs. APs with an 802.11b PC Card or 
a 5 GHz Upgrade Kit support only one VLAN/SSID per radio.
VLAN Workgroups
The correct VLAN assignment can be verified by pinging the AP to ensure 
connectivity, by pinging the switch to ensure VLAN properties, and by 
pinging hosts past the switch to confirm the switch is functional. 
Ultimately, traffic can be “sniffed” on the Ethernet or WDS interfaces (if 
configured) using third-party packages. Most problems can be avoided by 
ensuring that 802.1Q compliant VLAN tags containing the proper VLAN 
ID have been inserted in the bridged frames. The VLAN ID in the header 
should correspond to the user’s assigned network name.
