Website Interface speed 10mbps while the Node shows 1000Mbps everywhere

RoyalEF

We're running 8.5.1 and seeing a few random interfaces on Cisco 3750s being properly discovered and the Interface Details all show the correct speeds(1Gb), but on  the website Interfaces show 10Mb.  The graphs on the Web are using the 10Mbps values, and our advanced alerts are being triggered because they are showing 60% utilization (6 mbps on a 1000Mbps port, but shown on the website at 6/10)

Anybody seen this bug?

We're trying to slot in an upgrade over the next two months, but I'm wondeirng if there is a workaround prior to the upgrade.

I thought about deleting the interface or the node and letting it re-discover, but this is a critical switch and destroying the last year plus of performance data is much of a "fix".

We figured it out.   While the discovered speeds wee correct, the bad ones had Custom Bandwidths set.  I'm not sure who would set all of these Ethernet ports to a hard-set custom value.  Maybe some process flipped the custom switch on.  Or somebody did something without understanding why you shouldn't do that.   We're going through the switches ID'ing the screwed up custom values.
