PORT MIRRORING COMMANDS

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.

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.

 <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
