I'm trying to configure an advanced alert to trigger whenever a network interface exceeds 80% TX or RX utilization. This alone seems to be working very well. The problem comes when I try to exclude a small number of interfaces because I know that they regularly exceed 80% utilization and why.
I've tried setting up the alert with interface exclusions a couple of different ways. In this example I'd like the alert to trigger when any interface exceeds 80% RX or TX utilization, unless that interface name is GigabitEthernet9/5 or GigabitEthernet9/38. Both of these interfaces were selected from the drop-down pick list and not typed in manually so this isn't a case of mistyping the interface name.
Despite all attempts below the alert is still triggering for GigabitEthernet9/6 and GigabitEthernet9/38. Does anyone have any insight as to why?
