Port monitoring
If you designate a port on the switch for network monitoring, the port will appear in the Port VLAN Assignment screen and can be configured as a member of any VLAN. For information on how broadcast, multicast and unicast packets are tagged inside and outside of the VLAN to which the monitor port is assigned, see the section titled "VLAN-Related Problems" in the "Troubleshooting" appendix of the ArubaOS-Switch Management and Configuration Guide for your switch.
