Radio Port Configuration
Configuring Radio Settings
■ Set the radio adoption default preference ID to match the Wireless Edge Services
zl Module’s adoption preference ID, which allows the module to adopt any RPs
that it detects. To move an RP to a different module, change the preference ID
for one of the radios on that particular RP. (See “Configuring Advanced Prop-
erties for a Particular Radio” on page 3-31.)
■ Set the radio adoption default preference ID to match the ID configured on a
different Wireless Edge Services zl Module, pushing all RPs toward that second
module. You might use this option to have a single module pre-adopt all RPs.
You can then set adoption preference IDs in configurations targeted to specific
radios and move some of the RPs to different modules.
■ Leave the radio adoption default preference ID at 0 (the default), no matter the
ID on this Wireless Edge Services zl Module. This configuration allows the
module to adopt any RP that it detects, unless a preference ID set up in a targeted
configuration pushes the RP toward a different module.
Note Configuring the adoption preference ID in the radio adoption default configuration
is only one part of the overall process of configuring adoption preference IDs—and
not always a necessary one. See “Setting up Adoption Preference IDs to Control RP
Adoption” on page 10-23 of Chapter 10: “Redundancy Groups” for instructions on
this process.
To set the adoption preference ID for all RP radios that this Wireless Edge Services
zl Module adopts, complete these steps:
1. Select Network Setup > Radio Adoption Defaults and click the
Configuration tab.
2. Select the radio type and click the Edit button.
3. In the Adoption Preference ID field, enter a preference ID number from 1 through
65,535. (The default is 1.)
Set a matching adoption preference ID on the Wireless Edge Services zl Module
that should adopt these RPs when they are installed in their final location. (To
set the ID, on the Network Setup > Radio screen, click the Global Settings
button.)
4. Click the OK button.
To force another Wireless Edge Services zl Module to adopt a particular radio, change
the radio’s preference ID to the ID on that second module, as explained in “Config-
uring Advanced Properties for a Particular Radio” on page 3-31.
Enabling Support for a Short Preamble. As part of the 802.11 standards, stations
and radios are required to prepend a preamble to transmitted frames. A preamble is
a known string of bits that signals the destination device to prepare to receive data,
and alerts all devices sharing a common channel that a data transmission is beginning.
