How to collect packet capture on the WebSphere DataPower device in the continuous mode
Answer
Login to the WebSphere DataPower device through SSH to get to the Command Line Interface (CLI):
- Type co at the prompt to enter Global configuration mode.
- Type int <ethernet interface > where <ethernet interface> is one of the interfaces that is configured on the DataPower device
- Type "packet-capture temporary:///eth1trace.pcap -1 10000"
- Perform the test for which you would like to collect the packet capture
- As soon as you see the problem, on the command line type:
- Download the file through the CLI using the copy command
where 10000 is the file size in kilobytes (the file size can be in the range of 10 through 50000 kilobytes) and eth1trace.pcap is the name of the file to store the generated packet data.
no packet-capture temporary:///eth1trace.pcap
xi50(config)# copy temporary:///eth1trace.pcap
scp://test@x.xx.xx.xxx/trace1.pcap
Password: ******
File copy success
Alternatively, you can also download the file from the WebGUI. From the WebGUI, navigate to the File Management temporary directory > download the file.
For example:
xi50# co
Global configuration mode
xi50(config)# int eth1
Interface configuration mode (eth1 )
xi50(config-if[eth1])# packet-capture temporary:///eth1trace.pcap -1 10000 9000
Trace begun.
xi50(config-if[eth1])# no packet-capture temporary:///eth1trace.pcap
Packet capture to temporary:///eth1trace.pcap on eth1 Stopped.
Example of capturing packet traces for all interfaces:
xi50# co
Global configuration mode
xi50(config)# packet-capture-advanced all temporary:///all-capture.pcap -1 10000 9000
Trace begun.
xi50(config)# no packet-capture-advanced all temporary:///all-capture.pcap
Packet capture to temporary:///all-capture.pcap on all stopped.
This will start a rotating packet capture of 3 files, each with a size of 10MB
The number 3 is fixed and cannot be configured.
