What is hcxRpmPrevMaxNoise?

This read-only Integer32 reports the maximum noise level, in dBmV, sampled on this RPM I-Port during the previous, completed 15-minute period, per the description. It gives the admin a finalized worst-case noise spike reading for that specific input, useful for correlating with reported service problems around that time. For example, an admin checks hcxRpmPrevMaxNoise against the timestamp of a subscriber complaint behind that I-Port to see if a noise spike coincided.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.36.1.1.21
snmpwalk -v2c -c public <target> COM21-HCXRX-MIB::hcxRpmPrevMaxNoise

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.36.1.1.21.1
snmpget -v2c -c public <target> COM21-HCXRX-MIB::hcxRpmPrevMaxNoise.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hcxRpmPrevMaxNoise.1
