Configuring an Access Point Cluster (J-Web Procedure)

Add Cluster

Basic Settings

Cluster ID

Specifies the cluster Identifier.

Enter the cluster ID.

Cluster Name

Specifies the name of the cluster.

Enter the cluster name.

Interface

Specifies the interfaces that are part of this cluster.

Select the configured interface.

NTP Server

Specifies the NTP server name.

Provide NTP server IP address.

Default Cluster

Specifies this cluster as the default cluster for the interface.

Select the check box to make the cluster be the default.

Channel Management

Enables channel management.

Select the check box to enable channel management.

Country

Specifies the country of operation for the access point.

Select the country.

MAC Filtering

MAC Address

Specifies the list of MAC addresses that are allowed or denied access to the network through the access point.

Click Add to add a MAC address. To delete an address from the list, select the address and click Remove.

Action

Either allows only MAC addresses that are in the list (any client whose MAC address is not in the list is denied access to the network) or blocks MAC addresses that are in the list (any client whose MAC address appears on the list is denied access to the network).

Select allow or deny. By default, allow is selected.

Add Radio

Radio

Radio Type

Configures radio 1 or radio 2 on the access point.

Select the radio type. The default is Radio 1.

Enabled/Disabled

Specifies if the radio is on or off. If you turn off a radio, the access point sends disassociation frames to all wireless clients it is currently supporting so that the radio can be gracefully shut down and clients can start the association process with other available access points.

Select to enable or disable the radio.

Virtual Access Points

Configures, edits, or removes a virtual access point configuration.

Click one:

• Add—Creates a virtual access point configuration.
• Edit—Edits an existing virtual access point configuration.
• Remove—Removes an existing virtual access point configuration.

Radio Settings

Radio Options

Mode

Specifies the Physical Layer (PHY) standard used by the radio.

Select a mode.

Select one of the following:

• IEEE 802.11a
• IEEE 802.11b/g
• IEEE 802.11a/n
• IEEE 802.11b/g/n
• 5 GHz IEEE 802.11n
• 2.4 GHz IEEE 802.11n

Note: The modes available on your access point depend on the country code setting.

Channel bandwidth

(802.11n modes only) Allows use of 40-MHz channel or legacy 20-MHz channel.

Select a channel bandwidth.

Primary channel

(802.11n modes only) When channel bandwidth is set to 40 MHz, allows designation of either the upper or lower 20-MHz channel in the 40-MHz band as the primary channel.

Select a primary channel.

Fragmentation threshold

Configures size at which a frame is divided into multiple 802.11 frames.

Enter a value from 256 to 2346. The default is 2346.

RTS threshold

Sets packet size of a request to send (RTS) transmission.

Enter a value from 0 to 2347. The default is 2347.

Fixed multicast rate

Specifies the multicast transmission rate the access point supports.

Enter the fixed multicast rate.

Protection

Enables rules to guarantee that 802.11 transmissions do not cause interference with legacy clients or access points.

Note: This setting does not affect the ability of the client to associate with the access point.

Select check box to enable protection to auto.

SGI

Guard interval reduces inter-symbol and inter-carrier interferences. Enabling SGI reduces it from 800 ns to 400 ns, thereby improving throughput in 802.11n supported systems by up to 10%.

Select check box to disable short guard interval.

802.11d Support

Specifies the broadcast of country code in access point-enabled beacons and probe responses (IEEE 802.11d world mode).

Select to disable or enable.

More — Advanced Options

Supported Rates and Supported Basic Rates

Supported rates are the rates that the access point supports. Basic rates are the rates that the access point advertises to the network.

Select the supported rates and supported basic rates.

Broadcast Multicast Rate Limit

Specifies the rate limits for broadcast and multicast traffic can improve overall network performance by limiting the number of packets transmitted across the network.

Select the rate limit and rate limit bursts.

Quality of Service

Disable acknowledgement

Suppresses sending of acknowledgments by the access point when a frame is correctly received.

Select to disable.

Disable auto power save delivery

Disables automatic power save delivery (access point SD).

Select to disable.

Disable WIFI multimedia

Disables WMM.

Select to disable WMM.

Station Queue

Configures enhanced distributed channel access (EDCA) parameters for upstream traffic from the client to the access point.

Click + to open queues. Enter or select values for any queue. The queues available are:

• Background Queue
• Voice Queue
• Video Queue
• Best Effort Queue

Background Queue, Voice Queue, Video Queue, Best Effort Queue

Arbitration inter-frame space

Defines a period of time a client station must wait before it can access the wireless medium.

Enter a value from 1 to 255.

Transmit Opportunity limit

Specifies the duration during which the station is allowed to transmit.

Enter a value from 0 to 65,535.

Contention window size (Max):

In order to avoid collision, the station applies random backoff. The random backoff algorithm selects a value between a minimum contention window and a maximum contention window.

Select a value.

Contention window size (Min):

In order to avoid collision, the station applies random backoff. The random backoff algorithm selects a value between a minimum contention window and a maximum contention window.

Select a value.

AP Queue

Configures enhanced distributed channel access (EDCA) parameters for downstream traffic from the access point to the client.

Click + to open queues. Enter or select values for any queue. The queues available are:

• Background Queue
• Voice Queue
• Video Queue
• Best Effort Queue

Background Queue, Voice Queue, Video Queue, Best Effort Queue

Arbitration inter-frame space

Defines a period of time a client station must wait before it can access the wireless medium.

Enter a value from 1 to 255.

Maximum Burst

Defines the number of fragments, which can be transmitted using a single iteration of the Medium Access Mechanism.

Enter a value from 0 to 65535.

Contention window size (Max):

In order to avoid collision, the station applies random backoff. The random backoff algorithm selects a value between a minimum contention window and a maximum contention window.

Select a value.

Contention window size (Min):

In order to avoid collision, the station applies random backoff. The random backoff algorithm selects a value between a minimum contention window and a maximum contention window.

Select a value.
