Wan Tool Ipperf Syntax - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

The following example shows the results of the performance analysis for slot 8, port ge0:

WAN tool ipPerf syntax

When using the portCmd
• Source IP address. If the
remote peer's port number to connect to.
• Destination IP address.
• Source (transmitter) or sink (receiver). If the
and source IP address will be used to listen for new connections.
If the options are not specified the following defaults apply:
• Default port—3227
• Default runtime—forever
• Default display (refresh) interval—30 seconds
• Default size—1MSS
Following is the syntax for portCmd
portCmd
--
size] [-t time]
[-i interval] [-p port] [-q diffserv] [-v vlan_id] [-c L2_Cos]
where:
-s source_ip
-d destination_ipThe destination IP address.
The interval specified with the portCmd --ipPerf command with the -i option or the default,
30 seconds.
The current running test total time (in seconds) for the last --ipPerf command entered.
The bandwidth measured in the last interval. Bandwidth is defined as the total packets and
bytes sent. BW represents what the FCIP tunnel / FC application sees for throughput rather than
the Ethernet on-the-wire bytes.
The weighted bandwidth currently with a gain of 50 percent.
The number of TCP retransmits. This number is an average rate over the last display interval.
The TCP smoothed round-trip time (RTT) and variance estimate in milliseconds.
The path MTU. This is the largest IP-layer datagram that can be transmitted over the end-to-end
path without fragmentation. This value is measured in bytes and includes the IP header and
payload. Note: There is limited support for black hole PMTU detection. If the Jumbo PMTU
(anything over 1500) does not work, --ipPerf tries 1500 bytes. If 1500 PMTU fails,
--ipPerf tries the lower PMTU of 1260 (the minimum PMTU supported for FCIP tunnels). If
1260 also fails, --ipPerf gives up. There is no support for aging. During black hole PMTU
detection the BW, WBW, Loss and PMTU values printed may not be accurate.
ipPerf option, you must specify the following:
--
ipPerf is started with –S (source mode), the port number specified is the
--
ipPerf to display end-to-end IP path performance statistics:
--
ipPerf [slot]/ge0|ge1 -s source_ip -d destination_ip -S|-R [-r rate] [-z
The source IP address.
ipPerf is started with –R (sink mode), the port number
