Has there been a fix for this issue?

I seem to have the same problem.... But to add to his question, I have been seeing "unknown" status beside the interface..

It also shows a flashing red to yellow to red icon.

IF SNMP was changed from SNMP to SNMPV1 (from version 8.1) Shy does Solarwinds detect a SNMP on a device but not the interface.

Any help is greatly appreciated.

I have the same issue, Win2k3 servers change to status unknown, even though they are showing as 'UP'... bizarre. Trying to find something to show that this is a Solarwinds issue, as our networks team thinks it is our Windows servers, but you don't get mass SNMP failure across a network, its unheard of...

Seems that there are more people affected by this than I first thought but I'm glad I'm not the only one having this!

I also have the same issue sporadically, specifically for windows servers(2K and 2K3). however when ever the NIC is showing "Unknown" status and blinking red and yellow I would restart SNMP on that box and it resolves it. I definitely would like to know if this is a bug or not?

I have the same issues with cisco devices, juniper devices, windows 2k3 server, etc. Very random in nature........

wxtornado-

If you have not already contributed to this thread or do not see your unknown devices being reported please add them to this thread ?PageIndex=1

Thanks-

this is not an issues of devices showing up as unknown this is the issue where SNMP fails on devices and the ping still makes it so the device stays green but all the interfaces on the device goes into unknown state.

wxtornado

Yeah, I just checked out the thread he was talking about and it's a different issue - you are right.

mark_wiggans

Sorry my mistake. The issue you describe about Cisco is usually related to the way they handle Interface IDs (IfIDs). When a router boots for the first time, it assigns an IfID to every interface starting with the first available IfID, which is always 0 the first time the device boots. But when the device reboots, the only thing it remembers is the number of the last IfID used, but not which IfID was assigned to which interface. This means that the IfID for each interface changes every time the device reboots.

You could try a MIB walk on the device to determine if it is returning a value of 6 for operstatus which stands for notPresent.
