Introduction
ProCurve Wireless Edge Services zl Module
Determining the Layer 3 Services Your Wireless Edge
Services zl Module Should Provide
When you are designing your network, you must consider which operations
you want the Wireless Edge Services zl Module to perform on wireless and
wired traffic. The answer often lies in the degree to which you want to separate
wireless traffic from your Ethernet network.
Using the Same VLANs for Wireless and Wired Users
If you want to handle wireless stations just as you do wired, you can configure
the Wireless Edge Services zl Module to assign WLAN traffic to the user VLANs
already in place in your wired network. On the wireless services-enabled
switch, you tag the module’s uplink port for those VLANs.
The module then forwards the traffic to the wireless services-enabled switch
at Layer 2, and the same devices that route and control traffic from traditional
users can handle traffic from the wireless users. In this scenario, the module
may perform few or none of the Layer 3 functions listed in “Wireless Edge
Services zl Module Operations” on page 1-17.
Figure 1-6 shows how the Wireless Edge Services zl Module can forward
traffic into VLANs used on a wired network.
