To analyse the network communication it is often necessary to record network traffic at a switch port. This can be implemented via a port mirroring on managed switches. By In doing this so the network traffic is mirrored from one or multiple switch ports to another switch port where a network participant records the traffic for later analysis.

Hinweis

The negotiated data rate of the destination port has to be at least equivalent to the negotiated data rate of the source port(s). Otherwise not all network traffic can be recorded which highly complicates the analysis or even renders it impossible. This is definitely to be considered when using multiple source ports. 

Examples:

  • Source port 1 GBit and destination port 1 GBit works
  • Source port 10 GBit and destination port 1 GBit does not work
  • Source ports three times 1 GBit and destination port 10 Gbit works
  • Source ports three times 10 GBit and destination port 10 GBit does not work
