a For PCs:
ping name_of_machine ↵
where name_of_machine is the name of the network management domain PC
b For workstations:
ping -s name_of_machine ↵
where name_of_machine is the name of the network management domain workstation
3 Review the output. The following shows sample output.
# ping -s name_of_machine

3 packets transmitted, 3 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/1
If the packets were received out of order, if some packets were dropped, or if
some packets took too long to complete the round trip, LAN congestion may be a
problem. Contact your IT department or check physical LAN connectivity
according to your company policy.
