3-39
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.
3.11.5 Example #2: REMOTE Port Mirroring
Port 1 on ATX #1 is the diagnostic port where the analyzer resides.
Ports 2 on ATX #2 is the mirrored port.
Port 5 on ATX #1 has an ip address of 134.141.100.1.
Port 4 on ATX #2 has an ip address of 134.141.100.2 .
(P4 has to have an ip address assigned so ATX #2 will have an ip to
ARP with.)
