Introduction
ProCurve Wireless Edge Services zl Module
By default, the only uplink VLAN is VLAN 1, and the module’s internal uplink port
is tagged for this VLAN. As for any switch port, you must tag the uplink port for
other VLANs if you want the module to forward network traffic in those VLANs.
The Wireless Edge Services zl Module never forwards untagged traffic to the wireless
services-enabled switch.
However, you do not have to tag the uplink for every VLAN that you create on the
module. Instead, you can have the module route traffic in a module VLAN to a VLAN
used in the wired network. This strategy isolates VLANs assigned to wireless users
from VLANs used for traditional, wired users.
You configure the actual tagging through the management interface on the wireless
services-enabled switch. (For instructions on tagging ports, see the management and
configuration guides for your zl switch.)
Figure 1-4 illustrates a network in which traffic from WLAN 1 is forwarded into the
Ethernet network in VLAN 10. Note that the station receives an IP address from the
network’s DHCP server (rather than from the module’s internal DHCP server).

Figure 1-5 illustrates a network in which the Wireless Edge Services zl Module
assigns traffic from WLAN 1 to VLAN 24, a VLAN reserved for wireless traffic. In
this network, the wireless station receives an IP address from the module’s internal
DHCP server, and the module routes the station’s traffic to servers in the private,
Ethernet network.
