Introduction
Addressing in the 700wl Series System in Chapter 2, and Chapter 4, Configuring Rights include more
extensive discussions of addressing considerations and NAT.
VLAN Tag Support
The HP System provides support for Virtual LAN (VLAN) tagging in several ways:
A client can be matched to a Connection Profile based on the VLAN ID (802.1Q tag) associated with the
client traffic.
The VLAN tag associate with the client traffic can be stripped, added, or rewritten before the traffic is
forwarded onto the network, based on the Access Policy in force for the client.
Matching a client to a Connection Profile based on the VLAN tag effectively enables you to assign an
Access Policy to clients in a specific VLAN. The Access Policies associated with the VLAN-specific
Connection Profiles can be configured to modify the VLAN tagging of these clients, if necessary. By
default, the tag associated with the client’s traffic is removed so the client’s traffic is sent on to the
network untagged. This scenario can be useful if you want to use the client’s VLAN membership only to
assign access rights for the client, and once the Access Policy is in place, the VLAN tag is no longer used.
Optionally you can configure the Access Policy to preserve the tag or you can replace the original tag
with a different tag.
The 700wl Series system also provides limited support for assigning IP addresses through DHCP based
on the VLAN tag of the incoming traffic. In the 700wl Series system, IP subnet ranges may be specified on
a port-by-port basis. In order to restrict an IP range to members of a specific VLAN, you can associate a
Connection Profile that filters for the desired VLAN with the port that defines the subnet range.
