CISCO2821 cannot get OID info by "snmpwalk -v 2c ....."

Hello everyone;
I have a problem with SNMP to get OID. The customer has two CISCO2821s to get OID information through snmpwalk. However, one of the devices can obtain OID information normally, but the other device does not get any information.
Their version information is the same;
The same configuration;
The only difference is that the normal device has "SNMP PING" compared to the show information, and the abnormal device does not have "SNMP PING". I want to know if this is the problem. Have you encountered such a problem?

Hello,

Do you believe you could post the complete (sanitized) configuration from the router that does not respond to the SNMP polls? Obviously, it is hard to say what might be the problem if we do not know the configuration of the device at all.

I am not sure about the "SNMP ping" you have mentioned - I do not know anything by that name.

Best regards,
Peter

HI Peter,
