Introduction
Radio Ports
■ Advanced radio settings—You will learn more about these options in
Chapter 3: “Radio Port Configuration.”
■ WLAN assignment—When you enable a WLAN, the Wireless Edge Ser-
vices zl Module automatically configures radios to support that WLAN. It
creates a radio configuration that specifies which SSIDs should be
assigned to which of the radio’s BSSIDs.
Note If you use advanced mode configuration, then you must manually specify
the WLAN assignment for a radio configuration.
The module deploys configurations in two ways:
■ It deploys a radio adoption default configuration to any newly adopted RP
radio.
■ It deploys override configurations to targeted radios.
Therefore, you can configure radio settings in two ways: for all RP radios or
for particular radios.
The Wireless Edge Services zl Module handles all WLAN settings. Indeed, one
of the advantages of the Wireless Edge Services zl Module is that you can more
quickly and easily establish a WLAN throughout an entire wireless network.
(If necessary, you can use advanced mode configuration to disable a WLAN
on a particular RP. See Chapter 4: “Wireless Local Area Networks (WLANs).”)
Note Do not confuse the module’s configuration with the RPs’ configurations. You
configure settings on the module, many, but not all of which, it pushes down
to RPs.
Radio Adoption Default Configurations
The Wireless Edge Services zl Module stores two radio adoption default
configurations, one for 802.11a radios and one for 802.11 bg radios. In this way,
each type of radio receives the correct channel, data rate sets, and other
settings that may differ according to the 802.11 mode.
When a new RP is adopted, the module sends it the default configuration for
its radio type. (If the RP has two radios, the module sends both configurations.)
The factory default configuration for the Wireless Edge Services zl Module
already includes the two radio adoption default configurations, with the
settings shown in Table 1-6. Note, however, that the configurations do not yet
include the country code, which you must set before the module can
deploy them.
