5. Type 2 to select Mirror-To Port and, when prompted, enter the number
of the port to function as the destination port. This is the port where the
traffic from the source ports will be copied to and where the network
analyzer will be located. You can specify only one destination port.
6. If you want to mirror the ingress (received) traffic on one or more ports,
type 3 to select Ingress Mirror Port and, when prompted, enter the
ports. You can identify the ports individually (for example, 3,7,10), as a
range (for example, 5-11), or both (for example, 2,4,11-14). Entering
“none” removes all ingress source ports.
7. If you want to mirror the egress (transmitted) traffic from one or more
ports, type 4 to select Egress Mirror Port and, when prompted, enter
the ports. Entering “none” removes all egress source ports.
To monitor both the ingress and egress traffic of the source ports, you
must specify the ports in both menu options 3 and 4.
The port mirror is now functional. Attach a network analyzer to the
destination port to monitor the traffic on the source ports.
8. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
