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.
