rdnRQuerySigQSignalNoise
Module: RDN-CMTS-MIB
OID (symbolic): RDN-CMTS-MIB::rdnRQuerySigQSignalNoise
OID (numeric): 1.3.6.1.4.1.4981.2.2.15.1.4
Node type: OBJECT-TYPE
Type: TenthdB
Access: read-only
Description: The last polled value of the CM's docsIfSigQSignalNoise MIB object, the downstream signal to noise ratio in TenthdB.
What is rdnRQuerySigQSignalNoise?
Read-only value in tenths of a dB giving the last-polled downstream signal-to-noise ratio reported by the modem (mirroring docsIfSigQSignalNoise). A low SNR here is a classic indicator of downstream RF plant problems and correlates with poor throughput or dropped connections.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4981.2.2.15.1.4 snmpwalk -v2c -c public <target> RDN-CMTS-MIB::rdnRQuerySigQSignalNoise
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4981.2.2.15.1.4.1 snmpget -v2c -c public <target> RDN-CMTS-MIB::rdnRQuerySigQSignalNoise.1
