D-Link DES-3326S Layer 3 Switch CLI Reference
config mirror port
Purpose
Used to configure a mirror port − source port pair on the Switch.
Syntax
config mirror port <port> add source ports <portlist>
[rx|tx|both]
Description This command allows a range of ports to have all of their traffic
also sent to a designated port, where a network sniffer or other
device can monitor the network traffic. In addition, you can specify
that only traffic received by or sent by one or both is mirrored to
the Target port.
Parameters
<port> − This specifies the Target port (the port where mirrored
packets will be sent).
source ports – The port or ports being mirrored. This cannot
include the Target port.
<portlist> − This specifies a range of ports that will be mirrored.
That is, the range of ports in which all traffic will be copied and
sent to the Target port. The port list is specified by listing the
lowest Switch number and the beginning port number on that
Switch, separated by a colon. Then the highest Switch number,
and the highest port number of the range (also separated by a
colon) are specified. The beginning and end of the port list range
are separated by a dash. For example, 1:3 specifies Switch
number 1, port 3. 2:4 specifies Switch number 2, port 4. 1:3-2:4
specifies all of the ports between Switch 1, port 3 and Switch 2,
port 4 − in numerical order.
rx − Allows the mirroring of only packets received by (flowing into)
the port or ports in the port list.
tx − Allows the mirroring of only packets sent to (flowing out of)
the port or ports in the port list.
both − Mirrors all the packets received or sent by the port or ports
in the port list.
Restrictions The Target port cannot be listed as a source port. Only
administrator-level users can issue this command.
Example usage:
To add the mirroring ports:
DES-3326S:4# config mirror port 1:5 add source ports 1:1-1:5 both
Command: config mirror port 1:5 add source ports 1:1-1:5 both
Success.
