ProSAFE Wireless Controller WC7600
untagged packets that are sent to the wireless controller are treated as management VLAN
traffic.
Note: Use a tagged VLAN or change the tagged VLAN ID only if the hubs
and switches on your LAN support 802.1Q. If they do not, and you
have not configured a tagged VLAN with the same VLAN ID on the
hubs and switches in your network, IP connectivity might be lost.
The wireless controller must have IP connectivity with the access points through the
management VLAN. If the wireless controller and the access points are on different
management VLANs, external VLAN routing must allow IP connectivity between the wireless
controller and the access points.
For information about how to configure management VLANs, see Manage the IP, VLAN, and
Link Aggregation Settings on page 62.
Client VLANs
Each authenticated wireless user is placed into a VLAN that determines the user’s DHCP
server, IP address, and Layer 2 connection. Although you could place all authenticated
wireless users into the single VLAN that is specified in the basic security profile, the wireless
controller allows you to group wireless users into separate VLANs based on the wireless
SSID to differentiate access to network resources. For example, you might place authorized
employee users into one VLAN, and itinerant users, such as contractors or guests, into a
separate VLAN. To use different VLANs, you must create different security profiles.
For information about how to configure regular VLANs, see Manage the IP, VLAN, and Link
Aggregation Settings on page 62.
DHCP Server
The wireless controller can function as a DHCP server and assign IP addresses to both
wireless and wired devices that are connected to it. You can add up to 64 DHCP server
pools, each assigned to a different VLAN.
DHCP option 43 (vendor-specific information) must be enabled on an external DHCP server.
Specifying an internal DHCP server on the wireless controller automatically enables DHCP
option 43 with the IP address of the wireless controller.
Client Authentication and Data Encryption
A user must authenticate to the WLAN to be able to access WLAN resources. The wireless
controller supports several types of security methods, including those methods that require
an external RADIUS or LDAP authentication server.
