Figure 6- 5. Setup Port Mirroring window
To configure a mirror port:
1. Select the Source Port from where you want to copy frames and the Target Port,
which receives the copies from the source port.
2. Select the Source Direction, Ingress, Egress, or Both and change the Status drop-
down menu to
Enabled.
3. Click Apply to make the changes take effect.
NOTE:
You cannot mirror a fast port onto a slower port. For example, if
you try to mirror the traffic from a 100 Mbps port onto a 10 Mbps port, this
can cause throughput problems. The port you are copying frames from
should always support an equal or lower speed than the port to which you
are sending the copies. In addition, the target port for the mirroring cannot
be a member of a trunk group. Please note a target port and a source port
cannot be the same port.
