• The storm control to the port set as a mirror target port becomes invalid.
• The mirror traffic is as follows according to the state of STP/RSTP/MSTP of the source
port.
When the mirror of two or more sources is possible, traffic corresponding to each state
is mirror.
STP, RSTP, state of MSTP, and mirror frame
Source port

Forwarding
• The presence of the VLAN tag of the packet output to the target port: about the
mirroring of the transmission frame.
It agrees to the tagging setting of the address source port of the packet. The VLAN tag
attaches to the packet output to the target port only when there is the one of the setting
with the VLAN tag in the address source port when there are two or more addresses of
the packet like the multicast, the broadcast, and the flooding, etc., and the packet is
output from two or more source ports. The content of tag becomes tag that should be
applied to the destination.
• As for the mirroring of the reception frame, presence and the content of the VLAN tag
of the packet output to the target port are corresponding to the packet when inputting it.
• When the reception frame mirroring is done rewriting DSCP and ip precedence, the
frame not the reception frame but after it changes is mirror.
• When STP and LLDP are defined in the target port of the mirror, the port cannot be
used.
• The storm control to the same port where the mirror target port was set becomes
invalid.

• Only a single port can be set as the mirrored target port on the device.
• The port which is set to be target port, can be used for forwarding.
• The destination MAC address, the source MAC address, and the presence or absence
of VLAN tag together with its contents sent to the target port may differ from those of
the packet actually sent from or received at the source port.
Cautions on backup setting
• If multiple ports defined as master or backup exist in the same backup group, the port with a
smaller number is enabled, and the port with a larger number is not linked up and it cannot be
used.
• If the master or backup port is undefined in the same backup group, the relevant port is not
linked up and it cannot be used.
