Ping
The Ping utility tests if a remote host can be reached and measures the round-trip
time for packets sent from the device to a destination device.
Ping operates by sending Internet Control Message Protocol (ICMP) echo request
packets to the target host and waiting for an ICMP response, sometimes called a
pong. It measures the round-trip time and records any packet loss.
To ping a host:
STEP 1 Click Administration > Ping.
STEP 2 Configure ping by entering the fields:
• Host Definition—Select whether to specify the source interface by its IP
address or name. This field influences the interfaces that are displayed in the
Source IP field, as described below.
• IP Version—If the source interface is identified by its IP address, select
either IPv4 or IPv6 to indicate that it will be entered in the selected format.
• Source IP—Select the source interface whose IPv4 address will be used as
the source IPv4 address for communication with the destination. If the Host
Definition field was By Name, all IPv4 and IPv6 addresses will be displayed
in this drop-down field. If the Host Definition field was By IP Address, only the
existing IP addresses of the type specified in the IP Version field will be
displayed.
NOTE If the Auto option is selected, the system computes the source
address based on the destination address.
