I've looked at a couple of thread regarding setting DFM thresholds to be other than the default 40%. (for instance, https://supportforums.cisco.com/message/3346767#3346767 ).
However, even after going into "Monitor, Fault Settings, Setup, Threshold Settings" and choosing DFM, System Defined Groups and changing the threshold for every instance of 1 GB Ethernet I could find (under Access Port, Interface and Trunk Port groups) LMS insists on generating DFM alerts for utilization exceeding the default 40% threshold. (And yes I did click on "Apply changes".)
Example below. What am I missing? (I looked for but cannot find any setting for ETHERNETCSMACD.)
I don't see any groups other than the default system-defined ones I mentioned. That's the only place I see any reference to port utilization.
Drilling down as you suggested shows that CiscoWorks believes "The selected group has no devices." (for all three DFM groups with 1 Gb Ethernet interfaces).
When I go in via Fault device details and drill down on a device interface (port) which is reporting high utilization, it shows as type ETHERNETCSMACD but I can't find any DFM settings for that type ID.
Output is attached.
It appears to indicate the object is considered a member of:
DFM@CiscoWorks/System Defined Groups/Trunk Port Groups/1 GB Ethernet
I confirmed that group's Utilization threshold is set to 75%:
I changed the settings (once again) for "DFM/System Defined Groups/Trunk Port Groups/1 GB Ethernet" to 75%. Clicked Save, OK, then Apply. System chews on that a minute and then reports changes applied. The dmctl get command above still reports the 40% setting.
Perhaps I should just open a TAC case and they can webex and/or debug. I thought I was missing some non-obvious (or obvious) step but it appears not.
