Mode Set the ping mode used when the availability of a critical resource is validated. Select from:
• arp-only – Use the Address Resolution Protocol (ARP) for only pinging the critical resource. ARP
is used to resolve hardware addresses when only the network layer address is known.
• arp-and-ping – Use both ARP and Internet Control Message Protocol (ICMP) for pinging the critical
resource and sending control messages (device not reachable, requested service not available,
etc.).
Port Provide the port on which the critical resource is available. Use the spinner control to set the port
number.
VLAN Define the VLAN on which the critical resource is available using the spinner control.

13. Set the duration between two successive pings from the access point to critical resource. Define this value in seconds from
5 - 86,400. The default setting is 30 seconds.
14. Configure the IP address for Port-Limited Monitoring in the
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.
