Hi! I’m having issues scanning the swiches on my network, they have SNMP active and working, I can ping them, and manage them either by browser GUI or telnet and they are all up and working. Yet spiceworks refuse to even acknowledge there’s something on those IP’s.

I have 4 switches, two are currently being recognized okay, I.E. I change their host name and after a scan it updates on Spiceworks. While the other two as commented aren’t recognized by Spiceworks at all.

It’s curious that one of the switches that is not recognized properly used to be recognized (at least once) but then no more, even when the SNMP configuration and Security configuration is exactly the same as the other (that is currently working fine with Spiceworks).

What could this be?

you might want to post this in spiceworks support. instead of the vendor page.

It’s been moved now. hopefully somebody can help you out. if not, i’ve emailed support directly before. i think it is support@spiceworks.com they’ve always been very helpful.

In order for SW to scan switches, some have ACLs for SNMP traps, be sure you add your SW servers IP to this list otherwise the switch will reject the scan

Thing is, of those failing, one is a SG200-26, I have another SG200-26 working just right without configuring any access list. Both are exact same model of SG200-26, same firmware and everything. I’ll look into access lists anyway to see if that fixes the issue.

Also check for IPS/IDS, something has to be stopping SW seeing them

Are both the SW server and the Cisco switches using the same default gateway?

@ Rod-IT the SG200 doesn’t have an access list option, neither IPS or IDS that I can see. In the security options all it’s the same in both switches yet only one is seen by Spiceworks.

@ dbeato They weren’t. Now they are. However they still are invisible to Spiceworks.

Can you ping the switches from the SPiceworks Server?

Are they or their IPs on an exclusion list?

@dbeato Yes I can.

@Rod-IT No that I can see.

Curious thing, I’m using Paessler SNMP Tester and it does contact with the “rouge” SG200 with no problem. Is Spiceworks that seem to be not wanting anything to do with the IP where the switch is at.

Go to your device scanning page, disable all other scan ranges, add your switch by IP and scan only that one, does SW see it?

Already did that Rod-IT. I can ping it from the SW server, I can access it with the web gui using the IP address, and yet, Spiceworks insist there’s nothing plugged there.

14

Go to your SW install folder, in logs and look for production.log in here at the time of scan look for or search for the IP.

What is your Spiceworks Server OS then?

@ Rod-IT No show of the IP in question. In fact in the logs there’s no mention to almost any IP, mostly just the server IP and the DNS IP.

@ dbeato Windows 7 Professional SP1 64 bits

Crazy update! The SG200 switch suddenly got scanned again, after so many months of not being scanned. Now, I only have one switch not being recognized.

That is good running on Windows 7, any other applications on this Desktop?

Well, it’s my desktop, but mostly it run office, chrome, firefox and not much else besides Skype for business 2015. It’s running like this until we get a new server and can make use of a virtual machine for Spiceworks only (and another one for the network monitor).

So you don’t have network monitor in this server, right?
