network --tcpdump [--port <nfs | windows | replication | ost>]
Description
Filters TCP/IP packet information based on a specific port type. In this example, by specifying an OpenStorage
Technology (OST) port type using the DR Series system CLI network --tcpdump --port ost command.
Syntax
network --tcpdump --port ost
Result
Successfully started tcpdump, please use "network --tcpdump --stop" to stop.

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).
