Switch Setup
The Switch Setup screen allows you to set up and configure global device features.
10.1 Switch Modes
The VES-1616FE-55A supports daisychain and aggregation switch modes.
10.1.1 Daisychain Switch Mode
Daisychain switch mode sets the VES-1616FE-55A to use Ethernet port one (ENET 1) as an
uplink port to connect to the Ethernet backbone and Ethernet port two (ENET 2) to connect to
another (daisychained or subtending) VES-1616FE-55A. When you daisychain multiple VES-
1616FE-55A they must all be set to daisychain mode.
Daisychain switch mode with port isolation enabled blocks communications between
subscriber ports on an individual VES-1616FE-55A and between the subscribers of any
daisychained VES-1616FE-55A (see Figure 48 on page 90 for an example). Use the same port
isolation setting on all VES-1616FE-55A that you set up in a daisychain.
10.1.2 Port Isolation with Daisychain Switch Mode Example
In the example below, the VES-1616FE-55A 1 has its Ethernet port one (ENET 1) connected
to the Ethernet backbone switch (3) and it’s Ethernet port two (ENET2) connected to Ethernet
port one (ENET 1) of the daisychained VES-1616FE-55A (2).
With port isolation turned on, communications between A and B must first go through another
switch or router (3 in the figure). A and B also cannot communicate with C without their
communications going through another switch or router.
