network --iperf_client --server <ip address | hostname> [--port <number>] [--window_size

<num bytes [KB/MB]>] [--interval <num seconds>] [--time <num seconds>]

The DR Series system provides the --iperf set of DR Series system CLI commands (--iperf_client and --iperf_server) that

let you test network performance between any client and server on the network that you designate. In addition to testing

the network performance between these two designated endpoints, this set of --iperf commands also let you test if the

firewall allows a connection between these two points. You can filter the network performance test by using the

following options:

• --server, by the IP address or host name that you specify

• --port, by the port number that you specify

• --window_size, by the number of bytes, Kilobytes or Megabytes (KB/MB), that you specify

• --interval, by the number of seconds that you specify

• --time, by the number of seconds that you specify

NOTE: There are two conditions you must meet: 1) you must use ports with the --iperf_client and --iperf_server

commands that are not in use by any other system operations (if you do not define specific ports, the --iperf_client

and --iperf_server commands default to port 5001), and 2) these commands must be issued simultaneously.

Description

Tests network performance between a client and server using a designated port (use this command at the same time

you use the other --iperf command).

network --iperf_client --server acme-sw-02 --port 5001 --window_size 7KB --

interval 30 --time 60
