New Features and Modifications
•
Private VLAN – Allows layer-2 isolation between ports that share the same
broadcast domain (e.g. VLAN). This way, several ports can share the same
VLAN and access a single uplink port (e.g. internet connection) but still be
isolated from other ports. Isolation can be either single host-mode ports
which are isolated, or several ports grouped in community host-mode
ports.

•
Stack LAG – When several ports are connecting between two units, they
are automatically added to a stack LAG, hence enabling higher bandwidth
for traffic across the stack and providing stack link redundancy.
