Testing Network Latency
Testing Network Latency
To Test Network Latency
Step 1 Access the CLI and enter ping -s 1000 IP_address_of_another_machine_on_the_network. The
“-s 1000”argument simulates normal network activity by sending 1,000 bytes of dummy data to the other
IP address.
Step 2 After you receive several reply messages, enter Ctrl-C.
If there is no reply, the Cisco Unified MeetingPlace Audio Server system cannot make a network
connection to the machine that you specified. Verify the IP address and consult the internal networking
contacts.
Step 3 Confirm that there is 0 percent packet loss.
