Hello Friends,
I am working on project related to CATV, and would like to know if the below SNMP Metrics varies frequently. If so , i need to look for some script to pull the values periodically .
1.3.6.1.2.1.10.127.1.1.2.1.2.4 UpStreamFrequency
1.3.6.1.2.1.10.127.1.1.2.1.3.4 UpStreamWidth
1.3.6.1.2.1.10.127.1.2.2.1.17.2 docsIfCmStatusEqualizationData
Also please let me know how frequent the values will get changed, and what would be the right time interval to query
it very much depends on your setup,
you can have your cmts configured with a fixed upstream channel width and frequency i.e. on a cisco
cable upstream 0 frequency 25000000
cable upstream 0 channel-width 32000
in which the frequency is always 25 mhz and the channel width is always 3.2 mhz
or Dynamically
cable spectrum-group 2 band 25000000 38000000
cable upstream 0 spectrum-group 2
cable upstream 0 channel-width 3200000 1600000
Which will adjust the freq from 25 mhz to 38 mhz and change the channel-width from 3.2 to 1.6 Mhz in response to signal impairment (ingres)
docsIfCmStatusEqualizationData will always be changing, if you have pre-equalization on as it is the mechanism that overcomes noise.
Thank you @kwesibrunee.
