Configuring the ProCurve Wireless Edge Services zl Module
Radio Port Adoption
3. Whichever type of configuration you choose for the RP, add option 189 to
the configuration. For the option’s value, specify up to three IP addresses
of Wireless Edge Services zl Modules. Separate the addresses with spaces.
For example:
10.4.1.30 10.4.1.40 10.4.2.35
4. Ensure that all necessary helper addresses are in place in your network
infrastructure so that the RP’s DHCP request can reach the server.
5. Ensure that the RP’s default gateway can reach the IP addresses specified
in option 189.
6. The Wireless Edge Services zl Module’s internal uplink port must be
tagged for the VLAN on which RPs messages arrive—that is, the VLAN on
which the module has the IP address specified in option 189.
The module’s uplink port is probably already tagged for this VLAN. If so,
the RP is adopted without further configuration.
7. Install the RP in its final location, connecting it to a PoE device.
Enabling Layer 3 Adoption Through DNS Lookup
The DNS strategy has the advantage that the RP can receive a DHCP config-
uration that is probably already in place on your network’s DHCP server. In
fact, the RP might be able to connect to the network and immediately be
adopted at Layer 3. However, for this to occur, your DNS server must map the
default DNS name known by RPs to the Wireless Edge Services zl Module’s IP
address. If you have changed the module’s DNS name, you must pre-adopt the
RPs and configure the module to push down the new DNS name to them
(explained in step 4 on page 2-68).
Follow these steps to enable Layer 3 adoption:
1. Ensure that the RP has the proper bootloader code.
If the RP has the old boot code, you must have the Wireless Edge Services
zl Module pre-adopt the RP at Layer 2. As part of the adoption process,
this module will automatically update the RP’s bootloader code, as you
can check in the Device Information > Radio Adoption Statistics screen (see
Figure 2-35).
The code automatically updates.
