Port Mirroring Configurations

Port Mirroring Configurations 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.

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, because many packets will be dropped.

The following fields can be set:

Parameter

Description

Mirror Status

This enables or disables mirroring.

Target Port

This is the port where information will be duplicated and sent for capture and network

analysis.
