Parameters
<port> [add] | delete] source ports <portlist> [rx | tx | both]
Used to configure a mirror port – source port pair on the Switch.
config mirror port <port> add source ports <portlist> [rx | tx | both]
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.
port <port> – This specifies the Target port (the port where mirrored packets will be sent).The port is specified
by listing the lowest switch number and the beginning port number on that switch, separated by a colon. For
example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4.
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 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.
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.
