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
