Fabric OS 6.2 administrator guide 489
The following example shows the results of the performance analysis for slot 8, port ge0:
ipperf to 192.41.70.43 from IP interface 192.41.70.42 on 0/1:3227
Sampling frequency(30s) Total time(30s) BW:112.73MBps WBW:55.57MBps Loss(%):0.00
Delay(ms):23 PMTU:1500
Sampling frequency(30s) Total time(60s) BW:112.77MBps WBW:83.61MBps Loss(%):0.00
Delay(ms):23 PMTU:1500
Sampling frequency(30s) Total time(90s) BW:112.43MBps WBW:97.46MBps Loss(%):0.00
Delay(ms):22 PMTU:1500
Sampling frequency(30s) Total time(120s) BW:112.32MBps WBW:104.33MBps
Loss(%):0.00 Delay(ms):22 PMTU:1500
Sampling frequency(30s) Total time(150s) BW:112.15MBps WBW:107.69MBps
Loss(%):0.00 Delay(ms):23 PMTU:1500
Sampling frequency(30s) Total time(180s) BW:112.54MBps WBW:109.55MBps
Loss(%):0.00 Delay(ms):23 PMTU:1500
where:
Sampling frequencies
The interval specified with the
portCmd --ipPerf
command with the -i option or the default,
30 seconds.
Total Time
The current running test total time (in seconds) for the last
--ipPerf
command entered.
BW
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.
WBW
The weighted bandwidth currently with a gain of 50 percent.
Loss(%)
The number of TCP retransmits. This number is an average rate over the last display interval.
Delay(ms)
The TCP smoothed round-trip time (RTT) and variance estimate in milliseconds.
PMTU
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.
WAN tool ipPerf syntax
When using the
portCmd
--
ipPerf
option, you must specify the following:
•
Source IP address. If the
--
ipPerf
is started with
–S
(source mode), the port number specified is the
remote peer’s port number to connect to.
•
Destination IP address.
•
Source (transmitter) or sink (receiver). If the
--
ipPerf
is started with
–R
(sink mode), the port number
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
--
ipPerf
to display end-to-end IP path performance statistics:
portCmd
--
ipPerf [slot]/ge0|ge1 -s source_ip -d destination_ip -S|-R [-r rate] [-z
size] [-t time]
[-i interval] [-p port] [-q diffserv] [-v vlan_id] [-c L2_Cos]
where:
-s source_ip
The source IP address.
-d
destination_ip
The destination IP address.
