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
