guest-mode (SSID configuration)

To configure the radio interface to support guest mode, use the guest-mode command in SSID interface configuration mode. To disable the guest mode, use the no form of this command.

guest-mode

no guest-mode

Syntax Description

This command has no arguments or keywords.

Command Default

Guest mode is disabled.

Command Modes

SSID interface configuration

Command History

Release	Modification
12.2(4)JA	This command was introduced.
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

Related Commands

Command	Description
show running-config	Displays configuration information.
ssid	Specifies the SSID and enters SSID configuration mode.

information-element ssidl

To designate a Service Set Identifier (SSID) for inclusion in an SSIDL information element (IE) that the access point includes in its beacons, use the information-element ssidl command in SSID configuration mode.

information-element ssidl [ advertisement] [ wps]

no information-element ssidl

Syntax Description

advertisement	(Optional) Includes the SSID name and capabilities in the access point SSIDL IE.
wps	(Optional) Sets the WPS capability flag in the SSIDL IE.

Command Default

By default, the access point does not include SSIDL information elements in its beacons.

Command Modes

SSID configuration

Command History

Release	Modification
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

12.4(2)T	This command was integrated into Cisco IOS Release 12.4(2)T.

Usage Guidelines

Enable the infrastructure client feature to increase the reliability of multicast messages to workgroup bridges. When this feature is enabled, the access point sends directed packets containing the multicasts, which are retried if necessary, to the associated workgroup bridge.

Enable this feature only when necessary because it can greatly increase the load on the radio cell.

Examples

The following example shows how to configure a virtual interface for a workgroup bridge client:

Router(config-if)# infrastructure-client

Related Commands

Command	Description
show running-config	Displays configuration information.

Command Modes

SSID interface configuration

Command History

Release	Modification
12.2(4)JA	This command was introduced.
12.4(2)T	This command was integrated into Cisco IOS Release 12.4(2)T.

Usage Guidelines

Use this command to control the SSID that access points and bridges use when associating with one another.

A root access point only allows a repeater access point to associate using the infrastructure SSID, and a root bridge only allows a nonroot bridge to associate using the infrastructure SSID. Repeater access points and nonroot bridges use this SSID to associate with root devices.

Configure authentication types and VLANs for an SSID to control the security of access points and bridges.

Examples

The following example shows how to reserve the specified SSID for infrastructure associations on the wireless LAN:

Router(config-if-ssid)# infrastructure-ssid

Command Modes

Privileged EXEC (#)

Command History

Release	Modification
Cisco IOS XE Release 2.6	This command was introduced.
15.0(1)S	This command was integrated into Cisco IOS Release 15.0(1)S. The driver keyword was added.

Usage Guidelines

LSMPI is the virtual interface for the packet transfer between the IOS daemon (IOSd) and Linux kernel on RP through the Linux shared memory. Packets punted from the ESP to the RP are received by the Linux kernel of the RP. The Linux kernel sends those packets to the IOSD process through LSMPI.

The first section of statistics lists cumulative statistics from the local authenticator.

The second section lists statistics for each access point (NAS) authorized to use the local authenticator. The EAP-FAST statistics in this section include the following:

Auto provision success--the number of PACs generated automatically
Auto provision failure--the number of PACs not generated because of an invalid handshake packet or invalid username or password
PAC refresh--the number of PACs renewed by clients
Invalid PAC received--the number of PACs received that were expired, that the authenticator could not decrypt, or that were assigned to a client username not in the authenticator’s database

The third section lists stats for individual users. If a user is blocked and the lockout time is set to infinite, blocked appears at the end of the stat line for that user. If the lockout time is not infinite, Unblocked in x seconds appears at the end of the stat line for that user.

Use the clear radius local-server statistics command in privileged EXEC mode to reset local authenticator statistics to zero.

speed (access point radio)

To configure the data rates supported by the access point radio, use the speedcommand in interface configuration mode. To reset the data rates to the default values, use the no form of this command.

speed { data-rates | default | ofdm-throughput | range | throughput }

no speed

Syntax Description

data-rates	The data rates (in megabits per second [Mbps]) the access point uses to transmit unicast packets; multicast packets are sent at one of the basic data rates. The basic data rates set the access point to require the use of the specified data rates for all packets, both unicast and multicast. At least one of the access point’s data rates must be set to a basic setting. The client must support the basic rate you select or it cannot associate to the access point.
default	Sets data rates to the default settings. This option is supported on 5-GHz radios and 802.11g, 2.4-GHz radios only.
ofdm-throughput	Sets all Orthogonal Frequency Division Multiplex (OFDM) rates (6, 9, 12, 18, 24, 36, and 48) to basic and all (Cisco Centralized Key (CCK) rates (1, 2, 5.5, and 11) to disabled. Disables 802.11b protection mechanisms and provides maximum throughput for 802.11g clients. This setting prevents 802.11b clients from associating to the access point. This option is supported on 802.11g, 2.4-GHz radios only.
range	Sets the data rate for best radio range. On the 2.4-GHz radio, this selection configures the 1.0 data rate to basic and the other data rates to supported. On the 5-GHz radio, this selection configures the 6.0 data rate to basic and the other data rates to supported.
throughput	(Optional) Sets the data rate for best throughput. On the 2.4-GHz radio, all data rates are set to basic. On the 5-GHz radio, all data rates are set to basic. This option is supported on 5-GHz and 802.11b, 2.4-GHz radios only.

Command Default

On the 802.11b, 2.4-GHz radio, all data rates are set to basic by default. On the 802.11g, 2.4-GHz radio, data rates 1.0, 2.0, 5.5, 6.0, 11.0, 12.0, and 24.0 are set to basic by default, and the other data rates are supported. On the 5-GHz radio, data rates 6.0, 12.0, and 24.0 are set to basic by default, and the other data rates are supported.

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 be1, 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-ratesvalue 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

Command History

Release	Modification
12.2(4)JA	This command was introduced.
12.2(13)JA	This command was modified to support four traffic classes (best-effort, background, video, and voice) instead of eight (0-7).
12.4(2)T	This command was integrated into Cisco IOS Release 12.4(2)T.

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.

Table 4

Default QoS Radio Traffic Class Definitions for Access Points

Class of Service	Min Contention Window	Max Contention Window	Fixed Slot Time
Best effort	5	10	2
Background	6	10	3
Video <100 ms latency	4	8	2
Voice <100 ms latency	2	8	2

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
