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).
