Pinging a Host
Ping is a utility used to test if a remote host can be reached and to measure 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 hosts by their IP address or
name.
• IP Version—If the host is identified by its IP address, select either IPv4 or
IPv6 to indicate that it will be entered in the selected format.
• IPv6 Address Type—Select Link Local or Global as the type of IPv6
address to enter.
- 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.
• Host 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.
• Ping Interval—Length of time the system waits between ping packets. Ping
is repeated the number of times configured in the "Number of Pings" field,
whether the ping succeeds or not. Choose to use the default interval or
specify your own value.
• Number of Pings—The number of times the ping operation is performed.
Choose to use the default or specify your own value.
