To define a critical resource's monitoring interval:
Select the Monitor Interval tab.
Set Monitor Interval as the duration between two successive pings to the critical resource. Define this value in seconds from 5 - 86,400. The default setting is 30 seconds.
Set the Source IP for Port-Limited Monitoring to define the IP address used as the source address in ARP packets used to detect a critical resource on a layer 2 interface. Generally, the source address 0.0.0.0 is used in the APR packets used to detect critical resources. However, some devices do not support the above IP address and drop the ARP packets. Use this field to provide an IP address specifically used for this purpose. The IP address used for Port-Limited Monitoring must be different from the IP address configured on the device.
Set the Monitoring Retries before Marking Resource as DOWN for the number of retry connection attempts (1 - 10) permitted before this device connection is defined as down (offline). The default setting is three connection attempts.
Select OK to save the changes to the critical resource monitor interval. Select Reset to revert to the last saved configuration.
