How do I configure SNMP v1/2 on a Cisco SG200-50?

Hello,

I have an SG200-50 small business switch that I need to configure SNMP on.  It has the latest firmware and boot code installed on it and so the SNMP configuration tab appears in the GUI.

However, when I enable SNMP in the TCP/UDP services page on the switch and create a RO community string (let's say 'public') it is completely unreachable via SNMP.

I have configured other switches in the past for SNMP and it was always as simple as enabling SNMP (if necessary) and creating a community string for access.  I don't understand what could be mucking this up here.

Under the TCP/UDP services tab, the GUI says that the switch is listening on the SNMP port of UDP 161.

Am I missing something obvious?

Many Thanks,

Jon

Hi Jon, see if this helps- go to http://sbkb.cisco.com and search switches > snmp.  There is an article ID 3590 about setting up SNMP on these switches.  Unfortunately the site does not seem to allow linking directly to pages.

Hi Brandon,

Thanks so much for the quick reply! I followed exactly what was prescribed by the article you mentioned, but it still doesn't work.  So I decided to perform a port scan of the switch and I was able to determine that it is not listening on UDP 161 (SNMP) as the GUI claims that it is.  I am going to reboot it one more time, but besides that, I am at a loss as to what to do.

Thanks,

Jon

Strange.  You did scan connected directly to switch I guess?  What software version?  I do recall some time ago enabling SNMP on a bunch of 200 series switches and had to upgrade, but I think t was to get SNMP feature at all, not because of an issue with it not working.  Is the switch new?  It comes with free phone support from Cisco.

Thanks Brandon.  Yes, I had to upgrade the firmware initially to gain access to the SNMP management features.  They weren't available out-of-the-box.

I will probably call Cisco for support whenever I have a free moment.

Hello,

You just need to enable snmp service on the Security->TCP UDP Services page.
