Static WEP Tab
All of the settings on the Static WEP tab are explained in the sections on
the service profile wizards.
Authorization Attributes Tab
The Authorization Attributes tab lists the default authorization attributes for
the SSID. When a user is authorized for the SSID, the switch applies the default
attributes to the user unless those attributes are otherwise specified. For
example, if a default session-timeout is set for the SSID, and the
session-timeout attribute is not defined as part of the individual user or the
user’s group, the switch assigns the SSID’s default session-timeout to the user.
Where applicable, the service profile wizards allow you to specify the
SSID’s default VLAN but do not allow configuration of the other default
attributes.
To change the default VLAN, select it from the VLAN-Name box. To set
other default attributes, click in the value column and type the values.
(For more information about attributes and how they are selected, see
the “Assigning Authorization Attributes” section in the “Configuring
AAA for Network Users” chapter of the
Wireless LAN Switch and
Controller Configuration Guide .)
Broadcast Settings Tab
The Broadcast Settings tab lists the settings for the following broadcast
control features. These features help enhance throughput for client data
by reducing the amount of bandwidth used by broadcast traffic.
„
Proxy ARP—WX responds on behalf of wireless clients to ARP requests
for their IP addresses.
„
DHCP Restrict—WX captures and does not forward any traffic except
DHCP traffic for a wireless client who is still being authenticated and
authorized.
„
No Broadcast—Sends unicasts to clients for ARP requests and DHCP
Offers and Acks instead of forwarding them as multicasts.
All these broadcast control options are disabled by default.
