The Port Mirroring Window 6-3
ATX Port Mirroring
Figure 6-1. The ATX Port Mirroring Window
The Port Mirroring window features a port selection area (at the right side of the
window), with selection buttons for each of the ATX’s managed ports.
The left side of this window features fields which allow you to select the mirror
type (local, remote, or off), and specify a diagnostic port. Selection buttons below
these fields allow you to either discard or truncate oversized packets that arrive at
a local diagnostic port.
Configuring Port Mirroring
The Port Mirroring window is used differently depending upon whether the
ports being mirrored are local (i.e., being managed by the ATX you are modeling)
or remote (i.e., being managed by another ATX in your network that is sending
mirrored traffic to the ATX you are modeling). If you are mirroring traffic to a
remote ATX, you must configure mirroring on both the local and remote devices.
NOTE
The local management port (i.e., port 1) is not available for mirroring, and is therefore
grayed out.
