Chapter 1 Overview
Features
Features
This section lists features supported on access points running Cisco IOS software.
• Access Point Link Role Flexibility—This feature allows the user to configure root and non-root
bridging mode functionality, universal client mode, and support of a WGB client device, in addition
to a root access point on the radio interface.
Note Root/Non-Root bridging mode is supported only on modular ISR platforms, such as Cisco
3800
series , Cisco 2800 and Cisco 1841 series. Fixed ISR platforms, such as the Cisco 800
and Cisco 1800 do not support this feature.
• QoS Basic Service Set (QBSS) support—This feature aligns Cisco QBSS implementation with the
evolving 802.11e standard. The QBSS element of the access point’s beacon advertises channel load
instead of traffic load. A new configuration command, dot11 phone dot11e has been added in
Release 12.4 that allows the standard QBSS Load element to be sent in the beacon. This command
should be used when compatible phones are employed in the network.
• Secure Shell version 2 (SSHv2) support—SSH v2 is a standards-based protocol to provide secure
Telnet capability for router configuration and administration.
• Support for Multiple BSSIDs—This feature permits a single access point to appear to the WLAN as
multiple virtual access points. It does this by assigning an access point with multiple Basic Service
Set IDs (MBSSIDs) or MAC addresses.
To determine whether a radio supports multiple basic SSIDs, enter the show controllers command
for the radio interface. The radio supports multiple basic SSIDs if the results include this line:
Number of supported simultaneous BSSID on radio_interface: 8
• Support for Wi-Fi 802.11h and Dynamic Frequency Selection (DFS)—This feature allows access
points configured at the factory for use in Europe to detect radar signals such as military and weather
sources and switch channels on the access points.
• SNMPv3—This feature enables SNMPv3 support on Cisco wireless devices to provide an additional
level of security.
• World mode—Use this feature to communicate the access point’s regulatory setting information,
including maximum transmit power and available channels, to world mode-enabled clients. Clients
using world mode can be used in countries with different regulatory settings and automatically
conform to local regulations. World mode is supported only on the 2.4-GHz radio.
• Multiple SSIDs—Create up to 16 SSIDs on the wireless device and assign any combination of these
settings to each SSID:
–
Broadcast SSID mode for guests on your network
–
Client authentication methods
–
Maximum number of client associations
–
VLAN identifier
–
RADIUS accounting list identifier
–
A separate SSID for infrastructure devices such as repeaters and workgroup bridges
Note Only 10 SSIDs are supported on the Cisco 800 series platforms.
