Network Interface Configuration
Verify radio status

In order to assure proper operation during and after configurations, there are several status pages that provide valuable information. They are the Radio Status, Radio Detailed Status, and the Carrier Busy Test Pages.

The Radio1-802.11A/B Status Tabs displays the radio interface configuration and statistics , . The Configuration status descriptions are shown in Figure .

The Interface Resets indicates the number of times an interface has been completely reset. This reset occurs if packets queued for transmission were not sent within several seconds. This disruption may be caused by a malfunctioning modem that is not supplying the transmit clock signal or a cable problem on the serial line. If the system notices that the carrier detect line of a serial interface is operational but the line protocol is not, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.

The receive and transmit statistics are shown in Figure . Also, pay particular attention to the error statistics if there are problems with the WLAN .

The Network Interfaces > Radio0-802.11A/B Detailed Status Tabs are shown in Figures and . The radio settings are shown in Figure . The transmitter and receiver statistics descriptions are shown in Figures and . If the AP is in repeater mode, the following statistics will apply, which are shown in Figures and .

In IOS CLI, there are several commands which can monitor the AP radio status . Use the show interfaces dot11radio privileged EXEC command to display the radio interface configuration and statistics. The command syntax is as follows:

show interfaces dot11radio interface-number

The interface-number option specifies the radio interface number. The 2.4-GHz radio is radio 0. The 5-GHz radio is radio 1. An example is shown in Figures .

To gain a clearer picture of the interface at a given time, use the clear dot11 statistics privileged EXEC command to reset statistic information for a specific radio interface or for a particular client with a specified MAC address.

clear dot11 statistics{interface | mac-address}

The example below shows how to clear radio statistics for radio interface 0:

AP#clear dot11 statistics dot11radio 0
