Introduction
Managing a Wireless LAN System
An administrator uses a wireless services-enabled zl Switch to manage radio
ports in a Wireless LAN System from one centralized interface. This provides
the following:
■ System-wide configuration, enabling coordinated configuration of WLAN
policies, and security across multiple radio devices.
■ System-wide view, providing security and unapproved-AP detection.
■ System-wide access control and security policies across wired and wire-
less infrastructure, providing easier network security management when
ProCurve Identity Driven Manager is used.
Radio Port Licensing
A wireless services-enabled switch has a maximum number of radio ports that
it may adopt, based on the licenses installed.
■ Only a Module (J9051A) has licenses.
■ When a Module moves from one slot to another, or from one zl Switch to
another, its licenses remain the same.
■ A non-removable, 12 radio port license is installed at the factory. The
purchase and installation of a 12 RP License product increases the number
of radio port licenses in a Module by 12. The total number of radio port
licenses supported is 156.
■ Licenses can be uninstalled and reinstalled in another Module in groups
of 12 or 48.
■ A Redundant Wireless Edge Services zl Module is not licensed and cannot
independently adopt radio ports. However, these modules can adopt radio
ports as part of a Redundancy Group (see the next section).
Redundancy
Two wireless services-enabled switches can cooperate to reduce the chance
of disruption in the wireless service in the event of a switch or an intervening
network failure. A Module and one or more Redundant Modules, up to twelve
units, can be configured as members of a Redundancy Group. In the event of
a failure, radio ports previously adopted by the failed wireless services-
enabled switch automatically migrate to another member of the Redundancy
Group.
