D-Link DES-3350SR [36/184] Port mirroring

D-Link DES-3350SR Standalone Layer 3 Switch

Auto setting allows the port to automatically

determine the fastest settings the device the port

is connected to can handle, and then to use

those settings. The other options are 100M/Full,

100M/Half, 10M/Full, and 10M/Half. There is

no automatic adjustment of port settings with

any option other than Auto.

The target port is where information will be duplicated and sent for capture and network analysis. A network analyzer would be

attached to this port to capture packets duplicated from the source port.

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 48 100 Mbps Fast Ethernet ports), because many packets will be dropped.

The following fields can be set:

Parameter Description

Source Port Allows multiple ports to be mirrored. These

from either being received or transmitted.

packets.

Egress Selecting this option mirrors only transmitted

packets.

and transmitted packets.

Target Port This port is where information will be
