15: Maintenance iPerf Select to start an iPerf3 server or client to measure network throughput. The server will run in "one-off" mode. This means that it will handle one client connection and then terminate. The server will wait indefinitely for the client to connect. The client will time out if a connection is not made to a server within 15 seconds. For more information, visit the iPerf website. iPerf Mode: Select the mode (Server or Client). Two EMGs can be used to measure network throughput, one running in server mode and one running in client mode. iPerf Server: Specify the server name or IP address that the client connects to. iPerf Options: Enter options to configure the packets sent by the server or client. If no options are specified, the server or client will run with a default set of TCP packets. Set server port to listen on/connect to (default 5201): -p, --port n Format to report: -f, --format [kmgtKMGT] Pause n seconds between reports: -i, --interval n Bind to a host, an interface or multicast address: -B, --bind More detailed output: -V, --verbose Output in JavaScript Object Notation (JSON) format: -J, --json Note: The options below are supported on the client only: Set length of buffer to n (default 8 KB): -l, --length n[KMG] Use UDP rather than TCP: -u, --udp TCP window size (socket buffer size): -w, --window n[KMG] Set TCP/SCTP maximum segment size (MTU): -M, --set-mss n Set TCP/SCTP no delay, disabling Nagle's Algorithm: -N, --no-delay Set bandwidth to n bits/sec (default 1Mbit/sec, unlimited for TCP): -b, --bitrate n[KMG] Number of bytes to transmit (instead of -t): -n, --bytes n[KMG] Time in seconds to transmit for (default 10 secs): -t, --time n Set the IPv6 flow label: -L, --flowlabel n Omit the first n seconds: -O, --omit n Prefix every output line with this string: -T, --title str Number of blocks (packets) to transmit (instead of -t/-n): -k, --blockcount Set the IP type of service, 0-255. The usual prefixes for octal and hex can be used, i.e. 52, 064 and 0x34 all specify the same value: -S, --tos n Set the IP dscp value, either 0-63 or symbolic: --dscp n Note: The EMG uses iPerf version 3.x, which is incompatible with older iPerf versions. 3.
