Figure 7-46. Target Port Selection window
The target port is the port where information will be duplicated and sent for capture and network analysis. This is the port where a network analyzer would be attached to capture packets duplicated from the source port.
To select the source port(s) for mirroring, click the Port Mirroring Settings link on the Mirroring menu (under Configuration):
Figure 7-47. Setup Mirror Port Config window
Up to 25 entries can be made to the port mirroring table, but it should be noted that a faster port (a 1000 Mbps Gigabit Ethernet port, for example) should not be mirrored to a slower port (one of the 24 100 Mbps Fast Ethernet port), because many packets will be dropped.
The following fields can be set:
| Parameter | Description | |
| Source Port | Allows the entry of the port number | |
|
| of the port to be mirrored. This port | |
|
| is the source of the packets to be | |
|
| duplicated and forwarded to the | |
|
| Target port. | |
| Direction <Ingress> | This field can be toggled between | |
|
| Either, Ingress and Egress. Ingress | |
|
| mirrors only received packets, while | |
|
| Egress mirrors only transmitted | |
|
| packets. | |
