NAC Request Alarms

M_Nees — Thu, 08 Aug 2019 02:58:36 GMT

XMC contains 2 threshold alarms regarding to rate of NAC requests:

At which level are these threshold set as default ?
Where can i change this threshold values to my special demand ?

Looking inside of these alarms these are just string patterns in "nacappliance event log":

Here case answer:

The threshold values are warning 2000/min critical 4000/min Number of requests coming in to NAC from per switch with in a minute, so this is calculated on per switch basis.

The appliance properties to override them are:
warning RADIUS_REQUEST_WARNING_THRESHOLD
critical RADIUS_REQUEST_ALARM_THRESHOLD

Right click on the Engine groups from the Access control tab >> Engine properties and add the needed values accordingly.

Restart of the NAC service is required for this value to take effect.

addtional information:

there is no need to restart the XMC services for the changes to take effect, just an enforce should be enough, to restore back the values you can delete the entry and enforce it again, there should not be any other impact in operations due to this change
