zmirror
NAME
zmirror - Set packet mirroring on an ingress or egress port
SYNOPSIS
zmirror -a | -t
zmirror [-e] 
DESCRIPTION
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. 
NOTE: There are performance issues when trying to mirror more bandwidth than is 
available on the to port. 
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.
