Description
The distributed L2 tunneling mode supports L3 roaming for wireless clients without
forwarding any data traffic to the DWS-4000 Series switch. Use the menu to enable
or disable the mode.
L2 tunneling is recommended when the DWS-4000 Series switch does not support
hardware forwarding acceleration or hardware-based L2 tunnels.
Note:
1. When there is only one switch managing all APs and that switch goes down, all
APs shut down their radios and the tunnel is terminated. After the switch
recovers and the AP becomes managed again, the client that was previously
tunneling traffic will re-associate and obtain an IP address on the network where
its currently located. This IP address will be different from the IP address it was
using when it was tunneling, and the traffic will not be tunneled.
2. If the network has peer switches and the tunnel is established between the APs
managed by the peer switches then, when a switch managing the home AP fails,
the switch managing the association AP detects the failure and terminates the
tunnel. At this point the client is disassociated. When the client re-associates it
obtains a new IP address.
3. If the switch managing the association AP fails, then the scenario is the same as
in item 1 above. The AP takes down all radios and the clients disassociate.
Band steering is a technology that detects whether or not the wireless client is dual-
band capable, and if it is, it will push the client to connect to the less congested 5GHz
network. If band steering is enabled, APs will suppresses probe responses and 802.11
authentication responses on 2.4 GHz channels to provide opportunity or wireless
clients to associate on 5GHz bands. The factory default is disabled
• Enable: Enables the band steering mode
• Disable: Disables the band steering mode
Enter the name of the RADIUS server that the VAP uses for AP and client
authentications. The name can contain up to 32 alphanumeric characters. Spaces,
underscores, and dashes are also permitted.
Any RADIUS information you configure for the wireless network overrides the global
RADIUS information configured on the Wireless Global Configuration page.
The switch acts as the RADIUS client and performs all RADIUS transactions on behalf
of the APs and wireless clients.
Indicates whether the RADIUS authentication server is configured for the VAP. To
configure RADIUS server information, go to the LAN > Security > RADIUS > Server
Configuration page.
Enter the name of the RADIUS server that the VAP uses for reporting wireless client
associations and disassociations. The name can contain up to 32 alphanumeric
characters. Spaces, underscores, and dashes are also permitted.
Any RADIUS information you configure for the wireless network overrides the global
RADIUS information configured on the Wireless Global Configuration page.
Indicates whether the RADIUS accounting server is configured. To configure RADIUS
accounting server information, go to LAN > Security > RADIUS > Accounting Server
Configuration.
