Introduction
Radio Ports
only the higher data rates of 802.11g, but a radio in another area, which includes
802.11b stations, to operate in mixed mode. Or, you might want to dedicate a single
RP as a detector.
In such circumstances, you can configure settings that apply only to a particular radio
or radios. The module then deploys this new configuration to the targeted radios.
Note You can target an RP radio for override settings only if the RP has been detected by
the Wireless Edge Services zl Module, although the RP does not actually have to be
adopted. When the RP is adopted, the module sends the override configuration to its
radio, rather than the radio adoption default configuration. A radio configured before
the RP is adopted is said to have a static index type. Radios adopted with the default
configuration have a dynamic index type.
You configure settings for particular radios from the Network Setup > Radio screens,
as described in Chapter 3: “Radio Port Configuration.” The Wireless Edge Services
zl Module still automatically manages WLAN assignments for these radios (unless
you are using advanced mode configuration).
Note The Wireless Edge Services zl Module associates the radio’s MAC address with the
override configuration, so it persists even if the RP is powered down.
Communications Between an RP and the Wireless Edge
Services zl Module: Layer 2 and Layer 3 Adoption
The Wireless Edge Services zl Module must communicate with RPs in order to
control the wireless network. It must:
■ adopt RPs
■ deploy configurations to RPs, including radio settings, WLAN assignments, and
WLAN settings
■ forward traffic that is part of wireless users’ sessions to and from RPs
■ collect information from RPs
A module communicates with all of its adopted RPs. An RP is adopted when the
module identifies it and assumes responsibility for managing it.
When first powered up, an RP transmits three types of messages continuously until
it is adopted:
■ LLDP messages—signal the RP’s presence to a Wireless Edge Services zl
Module. You can customize the LLDP name for individual RPs or for all RPs
adopted by a module.
