Summary. Look at the lower portion of the screen under the graphic 
representation of the switch for the PID VID. The descriptor will end in the VID 
number. The version information is also shown on the product label on the back of 
the switch. The PID VID is located at the bottom of the label.
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.
IPv6 6-to-4 Tunnel support (SG500x and SG500XG product lines).
Auto image update – In addition to the already-supported auto 
configuration update using parameters received by DHCP, the device image 
can also be automatically updated.
Loopback detection – Detects network loops using non-BPDU frames, and 
usually used where spanning tree cannot be used.
