Mirroring
Note:
You can accomplish port mirroring using ACLs. See
for more information.
Mirroring configures the switch to copy all traffic associated with one or more ports, VLANs,
or virtual ports. A virtual port is a combination of a VLAN and a port. The monitor port or ports
can then be connected to a network analyzer or RMON probe for packet analysis. The
system uses a traffic filter that copies a group of traffic to the monitor port(s). You can have
only one monitor port or port list on the switch. This feature allows you to mirror multiple ports
or VLANs to a monitor port, while preserving the ability of a single protocol analyzer to track
and differentiate traffic within a broadcast domain (VLAN) and across broadcast domains (for
example, across VLANs when routing).

Note:
The mirroring filter limits discussed in this chapter do not apply when
you are working with Sentriant devices.
Up to 16 mirroring filters and 1 monitor port or 1 monitor port list can be configured. A monitor
port list may contain up to 16 ports.

Note:
On NETGEAR 8800 series switches, you can mirror up to 16 VLANs
on a given port.
Mirroring is disabled by default.
Note:
Frames that contain errors are not mirrored.
