Radio Ports
To control a radio port, a Module must have network connectivity to it. A radio
port VLAN supplies this connectivity. This VLAN contains the Module’s
internal downlink port as a tagged member, and the downlink radio port (the
port connected directly to the radio port on the local, or on an infrastructure,
switch) as an untagged member.
See Figure 1
for a summary of the VLAN configurations required to support
Layer 2 radio port and the internal Module uplink and downlink port
communications.

Note Routing may not be used in the communications path between the Wireless
Services-Enabled zl Switch and a radio port when a radio port is adopted at
Layer 2. For Layer 3 adoption, see “Radio Ports as Layer 3 Devices” on page 9
for more information.
