422 Configuring and monitoring FCIP tunneling
To start an
ipPerf
session
1. Configure the receiver test endpoint using the CP CLI.
The syntax for invoking the receiver test endpoint using
ipPerf
for slot8, port ge0 on an FR4-18i is as
follows:
portcmd --ipperf 8/ge0 -s 192.168.255.10 -d 192.168.255.100 -R
2. Configure the sender test endpoint using a similar CP CLI.
The syntax for invoking the sender test endpoint using
ipPerf
for slot8, port ge0 on an FR4-18i is as
follows:
portcmd --ipperf 8/ge0 -s 192.168.255.100 -d 192.168.255.10 –S
3. Use the
portCmd ipPerf
option specifying the slot and port of a switch.
The following example shows the results of the performance analysis for slot 8, port ge0:
In the example above, BW represents Bandwidth and Delay represents the round-trip-time (RTT) in
milliseconds. The output is printed after each display interval (if you do not specify an interval, the
default is 30 seconds). In the output, data is displayed as follows:
• First column—Time elapsed since the start of the test.
• Second column—Bandwidth observed in the last display interval using the following units:
• MBps—megabytes per second.
• Mbps—megabits per second
• KBps—kilobytes per second
• Kbps—kilobits per second
• Bps—bytes per second
• bps—bits per second
• Third column—The 30s weighted bandwidth
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
