dcxMACUpChannelLogSnrAveTimeconstant

Module: ARRIS-C3-MAC-MIB

OID (symbolic): ARRIS-C3-MAC-MIB::dcxMACUpChannelLogSnrAveTimeconstant

OID (numeric): 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.15

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: The averaging timeconstant used to calculate the per-logical channel MIB variable docsIfSigQSignalNoise. 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 dcxMACUpChannelLogSnrAveTimeconstant?

Averaging timeconstant (0-10) for SNR calculation; actual value 2^X. Higher X = smoother SNR averaging over time. Example: 5 = 32 sample average.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.15
snmpwalk -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACUpChannelLogSnrAveTimeconstant

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.15.1
snmpget -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACUpChannelLogSnrAveTimeconstant.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.15.1 i <value>
