dcxMACUpChannelLogC3SnrTimeconstant
Module: ARRIS-C3-MAC-MIB
OID (symbolic): ARRIS-C3-MAC-MIB::dcxMACUpChannelLogC3SnrTimeconstant
OID (numeric): 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.20
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The averaging timeconstant used to calculate the per-logical channel MIB variable dcxMACUpChannelSignalNoise. The averaging uses a logarithmic scale, so that the actual timeconstant used is 2^X, where X is the value configured for this object. Increasing the value of X increases the degree to which the SNR results are averaged over time, and reduces the sensitivity of the reported channel SNR to local oscillations in signal quality. Averaging can effectively be disabled by setting this object to 0
What is dcxMACUpChannelLogC3SnrTimeconstant?
Logarithmic SNR averaging timeconstant (0-10); actual 2^X. Controls SNR smoothing in channel statistics. Example: 4 = 16x average.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.20 snmpwalk -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACUpChannelLogC3SnrTimeconstant
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.20.1 snmpget -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACUpChannelLogC3SnrTimeconstant.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.20.1 i <value>
