Radio180211A Network Interface

Middle Portion of screen

Also on Network Interface screen:

■ Default Radio Channel: Permits the configuration of an explicit frequency for the AP to utilize or permits the AP to select the "Least Congested Channel" based upon 802.11 activity.

■ Least Congested Channel Search: Permits the configuration of explicit frequencies for the AP to search when determining frequency to use.

■ Radio Preamble: Configure either Long or Short, depending on network device capabilities.

■ Receive Antenna: Configure either Right/Left/Diversity antennas, depending on requirements and per any special installation

■ Transmit Antenna: Configure either Right/Left/Diversity antennas, depending on requirements and per any special installation

■ Aironet Extensions: Enabled or Disabled- enable to allow roaming and Cisco-specific security options

■ Ethernet Encapsulation Transform: Specify either RFC1042 or 802.1H- 802.1H permits optimal performance with Cisco equipment/ RFC1042 permits optimal interoperability

■ Reliable Multicast to WGB: If enabled, this parameter requires the acknowledgement of all packets transmit to WGB. Depending on network, this may result in lower aggregate throughput

■ Publicly Secure Packet Forwarding: If enabled, this parameter prevents communication between clients on a single AP

■ Beacon Period: This parameter controls the rate at which beacons are transmitted from the AP to the client devices. (in milliseconds)

■ Data Beacon Rate (DTIM): Rate at which Traffic Indicator Map information is sent to clients- indicating buffered data for client

■ Max. Data Retries: Maximum allowable retries for 802.11 packets

■ RTS Max. Retries: Maximum allowable retries for messages which are rejected due to packets beyond RTS threshold

■ Fragmentation Threshold: Maximum allowable size packet prior to fragmenting packet

■ RTS Threshold: Packet size (and larger) for which RTS messaging is used

■ Repeater Parent AP Timeout: The parameter allows the configuration of a timeout parameter for which the repeater AP will pause before seeking the "next" AP in it's list of valid parent AP's.

■ Repeater Parent AP MAC X: This parameter allows the assignment and prioritization of "Parent" AP's for the configured AP to associate to.

AWLF V3.1

■ Requested Status: This setting is useful for troubleshooting problems on your network. Up, the default setting, enables the Ethernet port for normal operation. Down disables the access point's Ethernet port. The Current Status line under the setting displays the current status of the Ethernet port. This field can also display Error, meaning the port is in an error condition.

■ Packet Forwarding: This setting is always set to Enabled for normal operation. For troubleshooting, you might want to set packet forwarding to Disabled, which prevents data from moving between the Ethernet and the radio. The Forwarding State line under the setting displays the current forwarding state. The state for normal operation is Forwarding. Four other settings are possible:

— Unknown—The state cannot be determined.

— Disabled—Forwarding capabilities are disabled.

— Blocking—The port is blocking transmission.

— Broken—This state reports an Ethernet port failure.

■ Default Unicast and Multicast Address Filter: MAC address filters allow or disallow the forwarding of unicast and multicast packets sent to specific MAC addresses. You can create a filter that passes traffic to all MAC addresses except those you specify, or you can create a filter that blocks traffic to all MAC addresses except those you specify. Read the "MAC Address Filtering" section for complete instructions on setting up MAC address filters. Unicast packets are addressed to just one device on the network. Multicast packets are addressed to multiple devices on the network. The drop-down menus for unicast and multicast address filters contain two options:

— Allowed—The access point forwards all traffic except packets sent to the MAC addresses listed as disallowed on the Address Filters page.

— Disallowed—The access point discards all traffic except packets sent to the MAC addresses listed as allowed on the Address Filters page.

Note For most configurations, you should leave Default Multicast Address Filter set to Allowed. If you intend to set it to Disallowed, add the broadcast MAC address (ffffffffffff) to the list of allowed addresses on the Address Filters page before changing the setting.

Note If you plan to discard traffic to all MAC addresses except those you specify (the Disallowed setting), be sure to enter your own MAC address as allowed on the Address Filters page.

■ Maximum Multicast Packets/Second: Use this setting to control the number of multicast packets that can pass through the Ethernet port each second. If you enter 0, the access point passes an unlimited number of multicast packets. If you enter a number other than 0, the device passes only that number of multicast packets per second.

■ Always Unblock Ethernet When STP is Disabled: Use this setting to maintain a bridge link when Spanning Tree Protocol (STP) is disabled. If STP is enabled, select no.

■ Optimize Ethernet for: Use this setting to specify how you want the Ethernet link to perform. You have two choices: performance and statistics collection. Selecting either results in a compromise. However, on a well-designed network, this compromise is virtually unnoticed.

■ Requested Status: This setting is useful for troubleshooting problems on your network. Up, the default setting, turns the radio on for normal operation. Down turns the access point's radio off.

■ Current Status: The Current Status line under the setting displays the current status of the radio port. This field can also display Error, meaning the port is operating but is in an error condition.

■ Packet Forwarding: This setting is always set to Enabled for normal operation. For troubleshooting, you might want to set packet forwarding to Disabled, which prevents data from moving between the Ethernet and the radio.

■ Forwarding State: The Forwarding State line under the setting displays the current forwarding state. For normal access point operation, the forwarding state is Forwarding. Four other states are possible:

— Unknown—The state cannot be determined.

— Disabled—Forwarding capabilities are disabled.

— Blocking—The port is blocking transmission. This is the state when no stations are associated.

— Broken—This state reports radio failure.

■ Radio Cell Role: This parameter is also located on the Express Setup Menu. Refer to the Express Setup Menu for the definition of this parameter.

■ SSID for use by Infrastructure Stations (such as Repeaters): This parameter is also located on the Express Setup Menu. Refer to the Express Setup Menu for the definition of this parameter.

■ Disallow Infrastructure Stations on any other SSID: Prevents repeaters or workgroup bridges from associating to SSIDs other than the infrastructure SSID. The default setting is No, so to invoke this condition, you must change the setting to Yes.

■ Use Aironet Extensions: Select yes or no to use Cisco Aironet 802.11 extensions. This setting must be set to yes (the default setting) to enable these features:

— Load balancing

— Message Integrity Check (MIC)

— Temporal Key Integrity Protocol (TKIP)

The extensions also improve the access point's ability to understand the capabilities of Cisco Aironet client devices associated with the access point.
