Network Device Registration Issue via SNMP network device extension,

[Muhammad-Ayaaz]

Hello Community, 

I tried to install a network device via an SNMP extension; it was a v3 configuration, and while adding the device to the EAG, I encountered an error issue. The following happened for 3 different network devices. Is there a configuration issue from my end or from the client's network device permissions?

Hi @Muhammad-Ayaaz 

You are encountering two distinct SNMPv3 issues across these devices:

1. LibErr="incoming packet is not authentic, discarding" (Authentication/Credentials Mismatch)
This is a cryptographic verification failure between the ActiveGate and the target device (192.168.79.10).

2. LibErr="request timeout (after 3 retries)" (Network Issue)
The ActiveGate sent requests to 192.168.79.11 on UDP port 161 for sysName (1.3.6.1.2.1.1.5.0), but received no response.

Test the connection directly from the ActiveGate CLI using snmpwalk or snmpget to validate the exact credentials and connectivity before configuring in Dynatrace.

Thanks,
