Update December 2, 2014 I did get a MIB collection for the RV320 from Cisco support but I was unable to find anything more useful than what I had already discovered below. You can download the MIB file here:
WAN IP Addresses
The best find was
The MIB says this is “the IP address that this managed node has, when seen from the external WAN, or the Internet. For WAN type of Static IP only.” Fortunately, it seems to work even if your WANs use dynamic IPs.
.184.108.40.206.220.127.116.11.18.104.22.168.22.214.171.124 – WAN1 public IP address
.126.96.36.199.188.8.131.52.184.108.40.206.220.127.116.11 – WAN2 public IP address
This OID does seem to have some valid interface information. The interesting interfaces are the values ending in .6 = LAN (eth0), .7 = WAN1 (eth1), and .8 = WAN2 (eth2).
.18.104.22.168.22.214.171.124.1.6.6- MAC address of device
.126.96.36.199.188.8.131.52.1.6.7- WAN1 MAC address
.184.108.40.206.220.127.116.11.1.6.8– WAN2 MAC address
.18.104.22.168.22.214.171.124.1.8.6 thru .8
Should show operational status, but shows “up” even if no network cables are attached to the WAN ports. I’m ignoring this one.
Update January 12, 2015 After upgrading the firmware from 1.1.1.06 to 126.96.36.199, sometimes a WAN value will show “down” after a router reboot with no cable connected, so the initial status is unpredictable. However, if you connect, then disconnect cables from the WAN ports, ifOperStatus correctly shows “down”. In fact, if you connect a cable to WAN1, power on the router, then disconnect the cable, it will show “down”. So there may be some value in monitoring these OIDs. Obviously it should show the correct value from the start; Cisco has been notified of the issue.
Update April 6, 2015 Cisco has confirmed that they will not fix the issue where the initial SNMP status is incorrect. Maybe not a big deal but a disappointing that they choose to leave bugs in the product.
.188.8.131.52.184.108.40.206.1.10.6 thru .8 – Total octets in on LAN, WAN1, and WAN2
.220.127.116.11.18.104.22.168.1.16.6 thru .8 – Total octets out on LAN, WAN1, and WAN2
Have more useful RV320 OIDs? Let’s hear them! Would especially like to know about link status OIDs that would reveal up, down, inactive (connected but no Internet), etc.
Monitor in GFI
Once you have the OIDs, setting up the SNMP checks in GFI is fairly straightforward. See Eric Anthony’s article on All Things Max for more info:
