Effective Scalability
3Com's versatile solution can be deployed
on any existing Layer 2 or Layer 3 LAN
topology with no backbone or hardware
reconfiguration required. Wireless
controllers or switches and associated MAPs
can reside anywhere in the network, sepa-
rated by L2/L3 devices, and can operate as
an integrated infrastructure, making it easy
to scale or change as business needs dictate.
Description
Groups of 3Com wireless controllers and/or switches that share user information and authorizations as users
roam to support mobility and enforce security across the entire wireless network.
By providing a Layer 2 path for Layer 3 traffic, 3Com wireless controllers, switches and MAPs operate as an
integrated infrastructure separated by L2/L3 devices even in distributed remote networks, making it easy to
expand or modify the WLAN as needed.
Quick handoff of user information and authorizations within the Mobility Domain enables seamless roaming
with session integrity and mobility robust enough to support voice traffic.
Class-based traffic queuing at the MAP helps ensure that voice and other real-time applications receive the
class of service and quality of service they need over the WLAN.
Upgrade licenses in 24-MAP increments for the WX4400 increase support to a total of 96 MAPs
per controller for flexible expansion.
The WX1200 supplies both data and power to MAPs over Ethernet cabling for installation flexibility.
Advanced Encryption Standard (AES), Temporal Key Interchange Protocol (TKIP), and Wired Equivalent Privacy
(WEP) encryption performed at the MAP help protect all communications.
Enforces different security policies on a per-user or per-group basis for flexible, in-depth security control
and management.
Helps ensure that only authorized users access the network. Centralizes authentication control and
management of all network users.
Enables IT staff to assign policies that control per-user or per-group network access throughout the WLAN
for secure seamless roaming, and keeps user traffic separate and secure.
Specifies which MAP or LAN authentication ports a user or group can use, allowing IT staff to dynamically
apply access permissions based on attributes returned by the AAA server.
Wireless controllers and switches can shoulder backend encryption key generation and authentication tasks,
reducing the processing load and increasing the scale and efficiency of central AAA RADIUS servers while
reducing AAA traffic over the WLAN.
Allows IT staff to assign AAA policies to user, subnet, or device groups for convenient, efficient,
cost-effective WLAN administration.
Makes sure only trusted users and client devices access the network, by bonding 802.1X machine
authentication with 802.1X user authentication.
Lets IT staff control and restrict network resource access at predetermined times on an hourly, daily, or
weekly basis.
Allows IT staff to assign to add or override AAA-defined access permissions based on user location,
providing a choice of centralized and location-specific policy implementation.
The WX1200 supports up to 12 MAPs while
the WX4400 comes configured to support
24 MAPs and is expandable in increments of
24 MAPS to support up to 96 MAPs per
controller for "pay-as-you-grow" flexibility.
WX4400s and WX1200s can be mixed and
matched together within a Mobility Domain
to manage and control thousands of MAPs
for unparalleled scalability. 3Com wireless
controllers and switches already support
future wireless LAN capabilities, such as
wireless IP Telephony (VoIP), today, and
downloadable firmware upgrades will keep
your network current with developing
standards releases.
