Modes
The following table shows the modes in which this feature is available:
Ping
The Ping tool is useful for verifying the configuration and operation of the adaptive security appliance
and surrounding communications links, as well as for testing other network devices.
A ping is sent to an IP address and it returns a reply. This process enables network devices to discover,
identify, and test each other.
The Ping tool uses ICMP (as described in RFC-777 and RFC-792) to define an echo request and reply
transaction between two network devices. The echo request packet is sent to the IP address of a network
device. The receiving device reverses the source and destination address and sends the packet back as
the echo reply.
