12.4(2)T |
This command was integrated into Cisco IOS Release 12.4(2)T. |
Usage Guidelines
The access point can have one guest-mode service set identifier (SSID) or none. The guest-mode SSID is used in beacon frames and response frames to probe requests that specify the empty or wildcard SSID. If no guest-mode SSID exists, the beacon contains no SSID and probe requests with the wildcard SSID are ignored. Disabling the guest mode makes the networks slightly more secure. Enabling the guest mode helps clients that passively scan (do not transmit) associate with the access point. It also allows clients configured without a SSID to associate.
Examples
The following example shows how to set the wireless LAN (WLAN) into guest mode:
Router(config-if-ssid)# guest-mode
This example shows how to reset the guest-mode parameter to default values:
Router(config-if-ssid)# no guest-mode

|
|---|---|
12.3(2)JA |
This command was introduced. |
Usage Guidelines
When multiple basic SSIDs are enabled on the access point, the SSIDL IE does not contain a list of SSIDs; it contains only extended capabilities.
When you designate an SSID to be included in an SSIDL IE, client devices detect that the SSID is available, and they also detect the security settings required to associate using that SSID.
Examples
This example shows how to designate an SSID for inclusion in the WPS IE:
Router(config-ssid)# information-element ssidl advertisement wps

This command was integrated into Cisco IOS Release 12.4(2)T. |
Usage Guidelines
Use the power client command to specify the desired transmitter power level for clients. The power setting is transmitted to the client device during association with the access point. Lower power levels reduce the radio cell size and interference between cells. The client software chooses the actual transmit power level, choosing between the lower of the access point value and the locally configured value. Maximum transmit power is regulated by the regulatory agency in the country of operation and is set during manufacture of the access point and client device.
Examples
The following example shows how to specify a 20-mW power level for client devices associated to the access point radio:
Router(config-if)# power client 20
This example shows how to disable power level requests:
Router(config-if)# no power client

Command Modes
Interface configuration
Command History
Usage Guidelines
At least one data rate must be specified. Multiple data rates are allowed.
An individual data rate can be set only to a basic or a nonbasic setting, not both. The basic setting allows transmission at the given rate for all packets, both unicast and multicast. At least one of the wireless device's data rates must be set to a basic setting.
For the 802.11b, 2.4-GHz radio, the data-rates value can be 1, 2, 5.5, 11.0, basic-1.0, basic-2.0, basic-5.5, or basic-11.0.
For the 802.11g, 2.4-GHz radio, the data-rates value can be 1.0, 2.0, 5.5, 6.0, 9.0, 11.0, 12.0, 18.0, 24.0, 36.0, 48.0, 54.0, basic-1.0, basic-2.0, basic-5.5, basic-6.0, basic-9.0, basic-11.0, basic-12.0, basic-18.0, basic-24.0, basic-36.0, basic-48.0, or basic-54.0.
The 5-GHz radio supports data rates of 6.0, 9.0, 12.0, 18.0, 24.0, 36.0, 48.0, 54.0, basic-6.0, basic-9.0, basic-12.0, basic-18.0, basic-24.0, basic-36.0, basic-48.0, or basic-54.0.
Data rates can be specified in any order, and basic rates need not precede nonbasic rates.
Examples
The following example shows how to set the radio data rates for best throughput:
Router(config-if)# speed throughput
This example shows how to set the radio data rates to support a low-speed client device while still supporting higher-speed client devices:
Router(config-if)# speed basic-1.0 2.0 5.5 11.0

12.4(2)T |
This command was integrated into Cisco IOS Release 12.4(2)T. |
Usage Guidelines
Use this command to specify a unique SSID for your wireless network. Several access points on a network, or subnetwork, can share an SSID. Use the no form of this command to remove the SSID, which inhibits clients that use that SSID from associating with the access point.
When you create an SSID in global configuration mode, you can assign or change the SSID attributes in both global configuration and interface configuration modes. However, when you create an SSID in interface configuration mode, you cannot assign or change its attributes in global configuration mode.
Examples
The following example shows how to create an SSID called Ivory-AP25:
Router(config-if)# ssid Ivory-AP25
This example shows how to remove the SSID named Ivory-AP25 and all its configuration settings:
Router(config-if)# no ssid Ivory-AP25
The following example shows how to:
•
Create an SSID in global configuration mode
•Configure the SSID for RADIUS accounting
•Set the maximum number of client devices that can associate using this SSID to 15
•Assign the SSID to a VLAN
•Assign the SSID to a radio interface
Router# configure terminal
Router(config)# dot11 ssid sample
Router(config-ssid)# accounting accounting-method-list
Router(config-ssid)# max-associations 15
Router(config-ssid)# vlan 3762

station-role
To specify the role of the radio interface, use the station-role command in interface configuration mode.
station-role {root [access-point | ap-only | bridge [wireless-clients]] | non-root [bridge]}
Syntax Description
Command Default
The role of the radio interface is root access point by default.
Command Modes
Interface configuration
Command History
Usage Guidelines
Use the station-role command to set the role of the radio interface.
If you set the station role to a root bridge, you can specify the distance from the root bridge to the nonroot bridge or bridges with which it communicates using the distance command in interface configuration mode. The distance command is supported only on bridges.
Examples
The following example shows how to configure an access point as a root bridge that accepts associations from client devices:
Router(config-if)# station-role root bridge wireless clients

traffic-class
To configure the radio interface quality of service (QoS) traffic class parameters for each of the four traffic types, use the traffic-class command in interface configuration mode. To reset a specific traffic class to the default value, use the no form of this command.
traffic-class {best-effort | background | video | voice} [cw-min min-value | cw-max max-value | fixed-slot backoff-interval]
no traffic-class
Syntax Description
Command Default
When QoS is enabled, the default traffic class settings for access points match the values in Table 7.
Command Modes
Interface configuration
Command History
Usage Guidelines
Use this command to control the backoff parameters for each class of traffic. Backoff parameters control how the radio accesses the airwaves. The cw-min and cw-max keywords specify the collision window as a power of 2. For example, if the value is set to 3, the contention window is 0 to 7 backoff slots (2 to the power 3 minus 1). The fixed-slot keyword specifies the number of backoff slots that are counted before the random backoff counter starts to count down.
Examples
The following example shows how to configure the best-effort traffic class for contention windows and fixed slot backoff values. Each time the backoff for best-effort is started, the backoff logic waits a minimum of the 802.11 SIFS time plus two backoff slots. It then begins counting down the 0 to 15 backoff slots in the contention window.
Router(config-if)# traffic-class best-effort cw-min 4 cw-max 10 fixed-slot 2
This example shows how to disable traffic class support:
Router(config-if)# no traffic-class

Command History
Usage Guidelines
If you do not know the user password, look up the NT value of the password in the authentication server database, and enter the NT hash as a hexadecimal string.
Examples
The following example shows that user "user1" has been allowed to authenticate using the local authentication server (using the password "userisok"). The user will be added to the group "team1":
Router(config-radsrv)# user user1 password userisok group team1

12.4(2)T |
This command was integrated into Cisco IOS Release 12.4(2)T. |
Usage Guidelines
You can configure the access point to support 802.11d world mode or Cisco legacy world mode.
With world mode enabled, the access point advertises the local settings, such as allowed frequencies and transmitter power levels. Clients with this capability then passively detect and adopt the advertised world settings, and then actively scan for the best access point. Cisco client devices running firmware version 5.30.17 or later detect whether the access point is using 802.11d or Cisco legacy world mode and automatically use world mode that matches the mode used by the access point.
This command is not supported on the 5-GHz radio interface.
Examples
The following example shows how to enable 802.11d world mode operation:
Router(config-if)# world-mode dot11d country-code TH both
