Overview
The port mirror feature allows for the unobtrusive monitoring of ingress or
egress traffic on one or more ports on a switch, without impacting network
performance or speed. It copies the traffic from specified ports to another
switch port where the traffic can be monitored with a network analyzer.
The port(s) whose traffic is mirrored is called the
source port(s)
. The port
where the traffic is copied to is referred to as the
destination port
.
Guidelines
Observe the following guidelines when creating a port mirror:
A standalone switch can have only one destination port.
An AT-9400Ts Stack can have only one destination port.
You can mirror more than one source port at a time. However, the
destination port may have to discard packets if the source ports are
very active.
The source and destination ports for a port mirror on a stand-alone
switch must be located on the same switch.
The destination and source ports for a port mirror in an AT-9400Ts
Stack can be located on different switches in the same stack.
You can mirror the ingress or egress traffic of the source ports, or both.
To create a mirror port for the Denial of Service defenses, specify only
the destination port for the mirrored traffic. The management software
automatically determines the source ports.
