zmirror - Set packet mirroring on an ingress or egress port

zmirror  -a | -t

zmirror  [-e] <from_list> <to_port>

zmirror sets packet mirroring from a given set of ports to one given port.  Turning on packet 
mirroring causes a copy of the packet to be sent to the to port. Any number of from ports can be 
mirrored to one to ports. 

After executing the following command, packets received on ports  1, 2 and 3 would be mirrored 
(copied and transmitted) to port 12.  This mirroring would be in addition to any Layer 3 or Layer 
2 switching.

zmirror zre1, zre2, zre3 zre12

To clear the current mirroring, use the -t option.  

The -e option can be used to indicate that packets being sent on a given port should be copied to 
the to port.  For example if the -e option is used as follows, the packets transmitted, as opposed 
to received, on ports 1, 2 or 3 would be mirrored to port 12.

zmirror -e zre1, zre2, zre3 zre12

The to port can also be the keyword 

cpu to indicate that packets should be forwarded to the on-

board processor.  The following example would mirror the contents of port 1, 2 or 3 to the on-
board processor:

zmirror zre1, zre2, zre3 cpu

The to port can be a single port or the keyword 

cpu.  The from port can be a list consisting of one 

or more ports.  The from port cannot be the 

cpu.  See the section on wildcards for discussion of 

from port lists.
