Parameters

Used to configure a mirror port − source port pair on the Switch.
config mirror port <port> | [add | delete] source ports <portlist> [rx

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, the user can specify that only
traffic received by or sent by one or both is mirrored to the Target port.
port <port> − This specifies the Target port (the port where mirrored
packets will be sent).
[add | delete] – Specify whether to add or delete source ports, which will
be specified using the following parameter.
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. rx − Allows the mirroring of only packets
received by (flowing into) the port or ports in the port list.
rx - Allows the mirroring of only packets sent from (flowing from) 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.
The Target port cannot be listed as a source port. Only administrator-
level users can issue this command.
