Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration
78-6030-03
Command Reference
Example
The following example will configure a collection interval of 1 hour and print to the screen every 30
seconds:
UBR04(config-if)# radio byteErrorHist collectionInterval 3600 periodic 30 sum false
show interfaces radio (histspec)
Use this command in privileged EXEC mode to display the details of the histogram specifications
currently configured. If none of the optional parameters are specified, all histogram specifications on the
modem card are displayed.
show interfaces radio slot/port histspec [statParam antenna_num [dsp dspnum]]
Syntax Description
slot Positive integer representing the Cisco uBR7200 series slot number.
port Positive integer representing the port number on that slot.
statParam {in | inr | constVariance | timingOffset | freqOffset | syncStatus | receivedPower
| gainSettingsIF | gainSettingsRF | totalGain}
The radio attribute whose data is to be collected as a histogram.
Note If the statParam is specified, antenna_num is conditionally required.
in (Interference + Noise) The interference plus noise power levels are computed by
the hardware on a burst-by-burst basis.
inr (Interference + Noise Ratio) The ratio of the interference plus noise power levels
captured by the first antenna to the second antenna on a burst-by-burst basis. This
value is specified as a log to base 2 number.
Note This parameter is available for a dual antenna system only.
constVariance (Constellation Variance) The average energy of the constellation error signal—the
error between the received (noisy) constellation symbol and the nearest ideal
constellation symbol. Constellation Variance is a measure of the Signal to
Interference plus Noise ratio (SINR) for that tone. On a single antenna system, it
represents (SINR)
–1
. On a dual antenna system, it represents a composite value
providing (SINR)
–1
.
timingOffset Represents the time delay variations detected in the radio link.
freqOffset Represents the carrier frequency offset between the slave radio and the master
radio.
syncStatus Represents the synchronization status.
