config mirror port
Description
This command allows a range of ports to
have all of their traffic also sent to a
desnigated 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 or both is
mirrored to the Target port.
Parameters
<port> − This specifies the Target port (the
port where mirrored packets will be sent).
<portlist> − This specifies a range of ports
that will be mirrored. That is, a range of
ports for which all traffic will be copied and
sent to the Target port. rx − Allows the
mirroring of only packets received (flowing
into) the port or ports in the port list. The
portlist 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 portlist range
are separated by a hyphen. For example,
1:3 would specify switch number 1, port 3;
2:4 specifies switch number 2, port 4.
Thus, 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
on the portlist.
