Important Considerations
■
When you specify a host name, the host name and its associated IP
address must be configured on a network name server. Also, you must
add the IP address on the name server to the list of name server
addresses that are associated with the network domain name. See “ip
dns domainName” earlier in this chapter for more information.
■
The burst option, when enabled, overrides the value set in the quiet
or
wait
option.
■
The burst option floods the network with Internet Control Message
Protocol (ICMP) echo packets and can cause network congestion. Do
not use the
burst
option during periods of heavy network traffic. Use
this option only as a diagnostic tool in a network that has many
routers to determine if one of the routers is not forwarding packets.
For example, you can set a high count value (1000 packets), and then
observe the run lights on the units: the run lights blink rapidly on
routers that are forwarding packets successfully, but remain unlighted,
or blink slowly, on routers that are not forwarding packets successfully.
