VLAN Management
Overview
Cisco Sx350, SG350X, SG350XG, Sx550X & SG550XG Series Managed Switches, Firmware Release 2.2.5.x
A private VLAN can be configured to span across multiple switches by setting inter-switch
ports as trunk ports and adding them to all VLANs in the private VLAN. Inter-switch trunk
ports send and receive tagged traffic of the private VLAN's various VLANs (primary, isolated
and the communities).
The switch supports 16 primary VLANs and 256 secondary VLANs.
