Description
Scheduled or on-demand RF scans identify unauthorized APs and ad-hoc networks and alert the central IT
staff. Dedicated APs can continually sweep the airspace for 24x7 protection in environments that require
higher security.
A single AP radio can sweep both 802.11a and 802.11b/g frequency bands and associated channels while
the WLAN stays up and running.
RF scans measure signal strength and usage; software tools dynamically adjust traffic loads, power,
RF footprint, or channel assignments to maximize coverage with capacity.
Centrally maintains and distributes MAP settings, eliminating the need to individually configure each device.
Provides all services based on user identity so things like virtual private group membership, access control
lists (ACLs), authentication, roaming policies and history, location tracking, bandwidth usage, and other
authorizations all stay with users as they roam. Also tells the IT manager who's connected, where they are,
where they've been, what services they're using, and what services they've used.
Wireless network management suite enables IT staff to successfully and cost-effectively plan, deploy,
monitor, and manage WLANs from a central point. Separately purchased required product.
Use the 3Com's Wireless Switch Manager to securely manage from anywhere. Use the built-in Web
browser via SSL or HTTPS, or command line interface via SSHv2 or Telnet. 3Com's Wireless Switch Manager
is interoperable with enterprise management tools such as 3Com Network Director (3ND) and HP OpenView.
Location-independent self-healing topology, Per-VLAN Spanning Tree (PVST+), and redundant MAP
configurations add network resiliency for demanding networks.
Distributing user authentication processing across multiple AAA servers increases network resiliency; servers
can be set up to track specified user session and accounting information for chargeback purposes.
A second, optional power supply can be installed for hot-swappable redundacy.
Support 1000 Mbps copper, or fiber with GBIC modules, for flexible Gigabit Ethernet backbone and
server connections.
