ER605 SNMP Stopped Working

ER605 SNMP Stopped Working

ER605 SNMP Stopped Working
ER605 SNMP Stopped Working
a week ago
Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.0 Build 20250428 Rel.18967

No other issues with the router other that SNMP stopped working 10 days ago, 29 day uptime since the last upgrade. 

 

All other switches and APs report SNMP data without issues.

 

Everything configured to use SNMPv3 via Omada Controller version 5.15.24.19

 
Any ideas ?

Thank you for your post.
Could you please confirm:

1. Are your other working switches and APs connected behind the ER605?
2. What device or software are you using as the manager?
3. Make sure the manager can ping the ER605 successfully and is on the ER605’s Allow List.
4. Ensure no ACL rules are blocking communication between the manager and the ER605.

1. Yes, all other switches an AP's are working fine behind the 605

2. Everything configured to use SNMPv3 via Omada Controller version 5.15.24.19 running on Debian 12

3. Yes, I don't have any other connectivity issues

4. No ACL rules in place

 

Nothing on the network or in the configuration changed, the SNMP data just stopped...

Most likely the issue lies in the settings on your manager (the SNMP software you’re using) or in the OID you’re querying. Try capturing packets to see what’s happening, or reconnect and reconfigure the manager from scratch.

As a last resort I rebooted the router and the SNMP feed started working again...

 

This has been working perfectly for three years now and this is the first time this has happened..., must be something in the latest update...

Stopped working yet again after I received a random router disconnect message via email alerts, which has also recently started happening.

 

The controller is plugged directly into the router BTW as is the SNMP server.

 

This is very basic, simple stuff that has worked for years without problems, please sort this out.
