Network Interfaces: Radio-802.11a/b/g Status
 

This window displays the radio interface configuration and statistics.

Configuration

Software Status

Indicates whether the interface has been enabled or disabled by the operator.

Hardware Status

Indicates whether the line protocol for the interface is up or down. Normally, if the Software Status is enabled, the Hardware Status is up. An error condition occurs if the Software Status is enabled and the Hardware Status is down.

Operational Rates

The data rates (expressed in megabits per second) the device uses for data transmission. The device always attempts to transmit at the highest rate selected. If obstacles or interference occur, the device steps down to the highest rate that enables data transmission.

Basic Rate

Enables transmission at this rate for all packets, both unicast and multicast. At least one data rate must be set as a basic rate.

Aironet Extensions

If compatibility with non-Cisco/Aironet products is required, deselect Aironet Extensions. Disabling this option limits several advanced features of the access point, such as load balancing, MIC, and TKIP.

Carrier Set

Indicates the regulatory domain on which the access point is operating. The carriers sets constrain the frequencies and power levels available. Some of the following regulatory domains can be indicated: Americas, EMEA (European Union), Israel, Japan, and China.

Current Radio Channel

The current channel and frequency of the 802.11b, 802.11a, or 802.11g radio.

Transmitter Power

The power level of the radio transmission. The default power setting is the highest transmit power allowed in your regulatory domain.

Role in Network

The access point can operate as an Access Point (Root) or as a Repeater (Non-Root). When operating as an Access Point (Root), it bridges wireless traffic to the wired LAN. When operating as a Repeater (Non-Root), it bridges wireless traffic to an access point that is connected to the wired LAN. The repeater is placed within range of an access point connected to the wired LAN. This placement extends the range of your infrastructure.

Current Parent (repeater mode only)

The IP address of the current parent for this repeater.

Interface Statistics

Interface Resets

The number of times an interface has been completely reset.

Receive/Transmit Statistics

Receive

5 min Input Rate (bits/sec)

The average number of bits per second received in the last 5 minutes.

5 min Input Rate (packets/sec)

The average number of packets per second received in the last 5 minutes.

Time Since Last Input

The number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface. Knowing this time helps you determine the traffic load on the interface and helps locate network problems.

Total Packets Input

The total number of error-free packets received by the system.

Total Bytes Input

The total number of bytes, including data and MAC encapsulation, received by the system.

Transmit

5 min Output Rate (bits/sec)

The average number of bits transmitted per second in the last 5 minutes.

5 min Output Rate (packets/sec)

The average number of packets transmitted per second in the last 5 minutes.

Time Since Last Output

The number of hours, minutes, and seconds since the last packet was successfully transmitted by the interface. Knowing this time helps you determine the traffic load on the interface and helps locate the network problems.

Total Packets Output

The total number of messages transmitted by the system.

Total Bytes Output

The total number of bytes, including data and MAC encapsulation, transmitted by the system.

Error Statistics

Receive

Total Input Errors

The total number of input related errors that occurred including runts, giants, no buffer, CRC, frame, overrun, and ignored counts.

Throttles

The number of times the receiver on the port was disabled, possibly because of buffer or processor overload.

Transmit

Total Output Errors

The sum of all errors that prevented the final transmission of datagrams from being examined.

Last Output Hang

The number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in the Time Since Last Input, Time Since Last Output, or Last Output Hang fields exceeds 24, the number of days and hours is printed.
