We are seeing utilization on interfaces above 100% in dashboard views.
Release : 20.2
Component : IM Reporting / Admin / Configuration
We report the speed that we get back from the SNMP MIB when we poll it.
If the speed is too low, the utilization calculations will be wrong.
In this example, the device I am using does not have a speed mismatch.
Open a shell to the DC that is polling this device and run:
snmpwalk -v 2c -c comm-string IP-address mib-2.interfaces
And in the results we see:
IF-MIB::ifDescr.9 = STRING: FastEthernet0/0.729
IF-MIB::ifSpeed.9 = Gauge32: 100000000
So the interface 0.729 is index 9, and the speed for index 9 is 100mbs (100000000)
So we have shown that the mib and the CAPC view match.
What did you find?
If the mib is presenting the wrong information, we will use the wrong information.
