Filter Group Commands

Filter Group Commands

The packet capture and filter function is disabled by default. Only one interface can be configured for capturing and filtering at a time.

When packet capture is enabled on an interface, the SecureStack C3 switch will capture 100 frames as close to sequentially as possible. These 100 frames will be placed into a buffer for inspection. If there is data in the buffer when the function is started, the buffer will be overwritten. Once 100 frames have been captured, the capture will stop. Filtering will be performed on the frames captured in the buffer. Therefore, only a subset of the frames captured will be available for display.

Note: Packet capture is sampling only and does not guarantee receipt of back to back packets.

One channel at a time can be supported, with up to three filters. Configured channel, filter, and buffer control information will be saved across resets, but captured frames within the buffer will not be saved.

This function cannot be used concurrently with port mirroring. The system will check to prevent concurrently enabling both functions, and a warning will be generated in the CLI if attempted.
