Retrieving SNR Data from an Operational CMTS Module
SNR measurement data can be directly retrieved from an operational CMTS module.
Use the snr display command, in Privileged EXEC mode, to retrieve SNR data from
a CMTS module, as follows:
MOT#
snr display {<
NUM
>{<
NUM
>}
where:
NUM
is 0.
NUM
is the upstream port number.
Retrieving SNR Data from a File System
SNR measurement data can be retrieved from a file system if a user has saved the
latest SNR measurement data to a file system with the snr store command. See
Storing SNR Measurement Data .
Use the snr display command, in Privileged EXEC mode, to retrieve SNR
measurement data from a file system, as follows:
MOT#
snr display { flash: < filename > <
WORD
> | nvram: < filename > <
WORD
>}
where:
nvram: < filename > retrieves the SNR measurement data from the NVRAM file
system.
flash: < filename > retrieves the SNR measurement data from the Flash file
system.
WORD
is the SNR measurement data filename - limit of 20 characters excluding
the "
.snr
" filename extension.
Configuring an SNR Offset
The cable upstream snr-offset command configures the display of an SNR value
with an offset. The offset can be configured for each upstream port up to a value of
100 (10 dB) in 10 (1 dB) increments. The offset value will be added to the SNR value
when it is displayed with the
show controllers and show interfaces cable upstream
signal-quality CLI commands and through SNMP. The offset value will not be added
to the actual SNR reading that is used by critical tasks such as Spectrum Management.
Use the cable upstream snr-offset command, in Interface Configuration mode, to
configure an SNR
offset
, as follows:
