Mirror Filters with LOCAL Port Mirroring:
• Desired - analyze IP traffic from station A (on P2) to station B (on
P3) and vice versa
• Implementation - add a PMEntry and PMExit filter to ports 2
and 3 with Protocol Type of 800(type IP in hex).
The reason for a PMEntry and PMExit filter is when A and B
communicate there is communication both ways, i.e. IP packets are
transmitted and received by P2.
