Packet Capture Menu
The Packet Capture menu contains commands for capturing packet flows.
Notes
*Live capture is not enabled when you are connected using a serial connection.
*For Alteon Physical appliances, the capture file size is limited to 1GB of cyclic captures. Ten files of 100M each are created in a cyclic (FIFO) order. The capture will stop upon user request.
*For Alteon VA, with less than 5GB RAM, the capture file size is limited to 50MB in a non-cyclic fashion (once 50MB data is captured, no further packets will be captured), with 5GB RAM or more, the capture file size is limited to 1GB of cyclic captures.
*The output displays GMT time and not the local time.
*If you transform the back-end flow to port 80, you will see clear text in the capture file.
*A syslog message is sent every 15 minutes while the packet capture is running.
Note: Alteon VA translates the MAC address for virtual servers and interfaces assigned by VMware to its own internal MAC address for internal processing. It switches the Alteon VA MAC address back to the VMware MAC address when it sends the packet back to the VMware switch. Therefore, the internal Alteon VA MAC address is displayed in some of the tables and dumps displayed on the console.
Note: Service interruptions may occur when using packet capture in certain situations; for example, with high traffic volume and only one CU allocated for the vADC. Radware recommends that you use packet capture sparingly (for troubleshooting purposes), during a maintenance window, or only in periods of low traffic volume.
