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:
Click Administration > Ping.
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.
If the Auto option is selected, the system computes the source address based on
NOTE
the destination address.
• Destination IPv6 Address Type—Select one of the following options:.
- Link Local—The IPv6 address uniquely identifies hosts on a single network link. A
link local address has a prefix of FE80, is not routable, and can be used for
communication only on the local network. Only one link local address is supported.
If a link local address exists on the interface, this entry replaces the address in the
configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
• Link Local Interface—If the IPv6 address type is Link Local, select from where it is
received.
• Destination IP Address/Name—Address or host name of the device to be pinged.
Whether this is an IP address or host name depends on the Host Definition.
