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.
network --tcpdump --port ost
Successfully started tcpdump, please use "network --tcpdump --stop" to stop.
For more information, see network --tcpdump [--port <nfs |||| rds>] [--pkt_size <128 - 32768>] [--file_size <0 - 100>] [--stop] [--host <ip address list>].
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:
|
|
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. |
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).
