ping

Protocol command that initiates an ICMP test of the last host passed to the dns command. If all packets fail to be returned by the host, an error will be generated.

The ping command sets the following global variables:

LAST_PING_DELAY - the average time response time of all ping packets.
LAST_PING_BADPACKETS - the number of packets that were not acknowledged by the host.

usage: ping [count] [badpercent] [maxdelayavg]

parameters:

req	name	type	description
N	count	expression	Number of ping packets to send to the server. Default is 15.
N	badpercent	expression	Percentage of packets that can be bad before an error is generated.
N	maxdelayavg	expression	Maximum average packet delay before an error is generated.
