MIB Walk on a Sonicwall TZ215 only finds every other port

I'm running PRTG Network Monitor to monitor a Sonicwall TZ215. I want to monitor bandwidth of ports. I do an autodiscovery, but PRTG only finds X0, X2, X4, X6 etc. However, if I run a scan from Solarwinds MIB Walk or Paessler's SNMP Tester, they find the ports LOOPBACK, X1, X3, X5 etc.
Anyway, I'm left with that PRTG doesn't find half of the ports.

How do I make PRTG find those ports, or how do I copy X0 and change all its OIDs to the ones that X1 uses (just add one to the last number, I presume) ?

Hi lefodnes,

Download http://www.paessler.com/tools/snmptester and scan against the SonicWALL, with the Option "Scan Available Standard Interfaces". Do this test twice with about one minute in between and then compare the counter numbers for this interface. Do they change?

Make sure your SonicOS is current as well.

You could try this too (http:Q_22705602.html#a19524563), but instead of WireShark use the now built-in Packet Capture feature (System > Diagnostics page, the Packet Capture tool).

Incidentally, SonicWALL can achieve this (monitoring the bandwidth of ports) natively as well in either ViewPoint or the Analyzer. You can get them if you are already licensed with CGSS or just purchase them a la carte: https://www.sonicwall.com/us/en/products/Analyzer.html#tab=compare

Let me know how it goes!

Hi deverseit. I already did the paessler snmp tester test, as you described. The counter number did not change, it was the same result again and again.
However, I found it to be a Sonicwall bug, since I had version 5.8.x.y something. After upgrading to, it now finds all ports. I never checked it with the packet capture tool.
