Basic WLAN Configuration
“Wireless LANs”
When creating or modifying a WLAN, the Basic Configuration screen is the first screen that displays as
part of the WLAN configuration screen flow. Use this screen to enable a WLAN, and define its SSID,
client behavior and VLAN assignments.
1 Select Configuration > Wireless > Wireless LANs to display a high-level display of the existing WLANs.
2 Select the Add button to create an additional WLAN, or select Edit to modify the properties of a
selected WLAN. WLANs can also be removed as they become obsolete by selecting Delete .
WLAN Status Lists each WLAN’s status as either Active or Shutdown . A green checkmark
defines the WLAN as available to clients on all radios where it has been
mapped. A red “X” defines the WLAN as shutdown, meaning even if the
WLAN is mapped to radios, it’s not available for clients to associate.
VLAN Pool Lists each WLAN’s current VLAN mapping. When a client associates with a
WLAN, the client is assigned a VLAN by means of load balance distribution.
The VLAN is picked from a pool assigned to the WLAN. Keep in mind
however, typical deployments only map a single VLAN to a WLAN. The use
of a pool is strictly optional.
Bridging Mode Lists each WLAN’s current bridging mode as either Local or Tunnel. Tunnel
is the default mode. Local infers VLAN traffic is bridges locally, Tunnel uses
a shared tunnel for bridging the WLAN’s VLAN traffic.
Authentication Type Displays the name of the authentication scheme each listed WLAN is using
to secure client transmissions.
None is listed if authentication is not used
within a WLAN. Refer to the Encryption Type column if no authentication is
used to verify there is some sort of data protection used with the WLAN, or
risk using this WLAN with no protection at all.
Encryption Type Displays the name of the encryption scheme each listed WLAN is using to
secure its client membership transmissions.
None is listed if encryption is not
used within this WLAN. Refer to the Authentication Type column if no
encryption is used to verify there is some sort of data protection used with
the WLAN or risk using this WLAN with no protection at all.
QoS Policy Lists the QoS policy applied to each listed WLAN. A QoS policy needs to be
custom selected (or created) for each WLAN in respect to the WLAN’s
intended client traffic, and the voice, video or normal data traffic it supports.
Association ACL Lists the Association ACL policy applied to each listed WLAN. An
Association ACL is a policy-based
Access Control List (ACL) that either
prevents or allows wireless clients from connecting to a access point
managed WLAN. The mapping of an Association ACL is strictly optional.
