Okay, so I just configured this box and I have snmp/mrtg looking like Gi2/2 might be failing/flapping? I wanted to get another opinion of whether this is an mrtg/snmp issue, or my port is having problems. Have any of you seen something like this before? Do I have something mis-configured?
it looks solid and then starts jumping up and down. Here's a downstream Gi2/4 int:
which doesn't seem to be jumpy, and here's a downstream Juniper box running a subset of the same traffic at the same time.
don't have console access to it, but my upstream just told me I'm running around 102Mb, and my current graph shows:
so clearly I have an instrumentation issue, has anyone seen mrtg/snmp suddenly appear to not read bandwidth right? My mrtg box is showing almost no load. It only seems to be happening to Gi2/2 so far, though I only have 4 ports polling snmp. Gi2/2 is connected to an upstream provider's Cisco fiber router. Not in front of that router to get the model #
Spun up another mrtg/snmp server and it looks more stable now:
HTH, in case anyone else is seeing the same thing on a box.
