4.1.13.5 Port
Monitoring
Port monitoring supports TX (egress) only, RX (ingress) only, and TX/RX monitoring. TX
monitoring sends any data that egress out checked TX source ports to a selected TX
destination port as well. RX monitoring sends any data that ingress in checked RX source
ports out to a selected RX destination port as well as sending the frame where it normally
would have gone. Note that keep all source ports unchecked in order to disable port
monitoring.
