Model: ER7406  
Hardware Version: V1
Firmware Version: 1.2.0 Build 20250218 Rel.17499

Hello,
I can not get data through SNMP using either v1/v2c or v3 version.
In case of SNMP v3 I'm using authorization authNoPriv and hash MD5 without success and always get connection Timeout.

Of course I have enabled both SNMP versions in the System Tools/SNMP settings.

Regards.

Please use following to check if the basic SNMP walk is working before adding gateways on any monitoring appliance.

 

V2

snmpwalk -v2c -c public 192.168.1.1

 

V3

snmpwalk -v3 -l authPriv -u <User> -a SHA -A <Auth> -x AES -X <Priv> 192.168.1.1

 

Replace <User>, <Auth>, and <Priv> with your actual SNMPv3 username and passwords.

  @navwork  As you probably know, in the ER7406 SNMPv3 configuration it is only possible to enter a username and password, so I basically cannot provide -x and -X.

 

In another thread on this forum I found information that ER7206 SNMPv3 uses authNoPriv and hash MD5. I also tried SHA but the result was the same.

Neither v1/v2 nor v3 work and get timeout every time.

The official documentation does not help in any way.

 

I assume there is some bug in the firmware v1.2.0 but I have no confirmation of this.
 

I can see that there is new firmware version. Maybe I'll try some day.

  @kacza can you share some logs output / screenshots?

What happens when you do SNMP walk on version 1/2.

Also can you confirm if the hardware is listing SNMP ports 161/162?
