dcxMACUpChannelSignalNoise
Module: ARRIS-C3-MAC-MIB
OID (symbolic): ARRIS-C3-MAC-MIB::dcxMACUpChannelSignalNoise
OID (numeric): 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.21
Node type: OBJECT-TYPE
Type: TenthdB
Access: read-only
Description: A measurement of the average signal/noise ratio for the logical upstream. The averaging may be controlled using the dcxMACUpChannelLogC3SnrTimeconstant variable
What is dcxMACUpChannelSignalNoise?
Current SNR in dB (TenthdB, e.g., 350 = 35.0 dB) measured on upstream. Tracks signal quality in real-time. Example: 320 dB (32 dB).
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.3.1.21 snmpwalk -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACUpChannelSignalNoise
Get a specific instance (index 1):
