Detailed introduction of packet capture method for A10 load balancing equipment

The following is a detailed introduction to the package capture method of A10 Load Balancer equipment. I hope it can bring some help to you in practical application. Load Balancer involves many things, but there are not many theories. There are many books on the Internet. Today, we will use the accumulated experience in the industry to make an answer.

Method 1:

A10 device AXdebug package capture description:

Log in to the A10 device from the command line and configure AXdebug packet capture policy as follows:

vThunder>en

Password:

vThunder#

vThunder#axdebug

vThunder(axdebug)#filter1

vThunder(axdebug-filter:1)#ip1.1.1.1 /24 #IP port is available here, refer to line help file.

vThunder(axdebug-filter:1)#exit

vThunder(axdebug)#capturesave test

After package capture is completed, you can stop capturing packages on the web page and download the capture files locally. You can analyze them through wireshark, as shown below:

Method 2:

If you want to see it directly on the device, you don't need to analyze it in depth. You can grab the package by debugging. The method is as follows:

The packet capture command is set as follows:

(1) First set the filter conditions:

Debugpacket [ l3 ip ] [ l4 TCP/UDP port number]

(2) Enable packet capture input

Debug monitor

(3) Analysis of packet capture output results

(4) End of packet capture input:

No debug all
