Functional Notes
The ping command helps diagnose basic IP network connectivity using the Packet InterNet Groper
program to repeatedly bounce Internet Control Message Protocol (ICMP) Echo_Request packets off a
system (using a specified IP address). The Secure Router OS allows executing a standard ping request to
a specified IP address or provides a set of prompts to configure a more specific ping configuration.
The following is a list of output messages from the ping command:
! Success
- Destination Host Unreachable
$ Invalid Host Address
X TTL Expired in Transit
? Unknown Host
* Request Timed Out
The following is a list of available extended ping fields with descriptions:
Target IP address: Specifies the IP address of the system to ping.
Repeat Count: Number of ping packets to send to the system (valid range: 1 to 1000000).
Datagram Size: Size (in bytes) of the ping packet (valid range: 1 to 1448).
Timeout in Seconds: If a ping response is not received within the timeout period, the ping is
considered unsuccessful (valid range: 1 to 5 seconds).
