Hi,
this is limits of standard sysUpTime.
When device support (report) extended sysuptime, like SNMP-FRAMEWORK-MIB::snmpEngineTime.0
device uptime shows more correctly.
Specially for linux (with net-snmp) we support 2 extended ways for fetch correct uptime: 1. https://docs.observium.org/unix_agent/ 2. https://docs.observium.org/device_linux/#accurate-uptime
Not sure about Netgear device, if possible please provide SNMP access to it (for my dev ip 77.222.50.30) or make full snmp dump like this: snmpwalk -v2c -c <community> --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk snmpwalk -v2c -c <community> --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk
Access or dump you can send me personally.
