SonicWALL Alerts

What actual alert messages do you get? The same message for all SNMP sensors of the device?

I'm getting SNMP error #-2003 with different error message details.

"No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)"

"1 hour interval average of 8.33 kbit/s (Traffic In) is unusually low for this hour of the week (No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003))"

This started a few weeks ago. Not sure if it's an issue with a PRTG software upgrade or not. I've changed nothing on my end and the errors just started out of nowhere.

This might be an issue with the appliance itself. Does this only apply to the interface sensors or others, such as SNMP Uptime as well? If not, please check the uptime using our SNMP Tester. If the query fails via the tool as well, check if there's a firmware update available or if a restart resolves the issue.

The SonicWALL has been up for 71 days. This issue only started in the last 30-35 days.

SNMP Tester worked fine for sysUpTimeInstance

Sorry, I've expressed myself ambigously - does the uptime sensor work continuously opposed to the SNMP Traffic Sensor? Or does it error out as well? If so, when it errors in PRTG, are you able to query it via the SNMP Uptime Tester? Does the interface scan fail as well?

Ping, HTTP and HTTPS all stay up. If there was a way to post a screen shot here, I would.

X0(LAN), X2(WAN), X4(WLAN), SonicWall System Health and all VPN interfaces/sensors show down in PRTG while the other 3 (Ping, HTTP and HTTPS) remain up.

All but Ping, HTTP and HTTPS are down right now in PRTG. I ran the SNMP Tester while these conditions were present. It is now NOT reporting Uptime.

Hi Mike,

Then it's possibly a condition on the appliance. Please check for an update or restart it to see if either resolves the issue :)

I did not update or reboot the device, but did find a KB article by SonicWALL about the "No Response" or "SNMP Error # -2003"

https://www.sonicwall.com/en-us/support/knowledge-base/170505495768662

The device was currently in error and as soon as I changed the SNMP setting on the SonicWALL the errors resolved.

Hi Mike,

Glad that the issue is resolved :)
