Znyx Networks bh5700 manual Zmirror Set packet mirroring on an ingress or egress port

zmirror

NAME

zmirror - Set packet mirroring on an ingress or egress port.

SYNOPSIS

zmirror -a -t

zmirror [-e] <from_list> <to_port>

DESCRIPTION

zmirror sets packet mirroring from a given set of ports to a 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 may be a significant performance impact 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 -toption.

The -eoption can be used to indicate that packets being sent on a given port should be copied to the to port. For example if the -eoption 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.
