The port mirroring commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
Command Parameters
config mirror port
<port> [add | delete] source ports <portlist> [rx | tx | both]
enable mirror
disable mirror
show mirror
Each command is listed, in detail, in the following sections.
NOTE:
As a stand-alone switch or as a master switch in a switch stack,
the switch number will be referred to as 15 for all configurations, graphs
and tables.
NOTE:
Port mirroring can only be used for regular ports on the master
DGS-3312SR switch. No port mirroring can be done between slave
switches in a stacking configuration, and the master switch.
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 <port>
−
This specifies the Target port (the port where
mirrored packets will be sent). 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.
add source ports
– The port or ports being mirrored. This cannot
include the Target port.
