CHAPTER 10
Switch Setup
The Switch Setup screen allows you to set up and configure global device features.
10.1 GARP Timer Setup
GARP (Generic Attribute Registration Protocol) allows network devices to register and de-
register attribute values with other GARP participants within a bridged LAN. GARP is a
protocol that provides a generic mechanism for protocols that serve a more specific
application, for example, GVRP (GARP VLAN Registration Protocol). GARP and GVRP are
the protocols used to automatically register VLAN membership across switches.
Switches join VLANs by making a declaration. A declaration is made by issuing a Join
message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration timeout values.
10.2 Switch Modes
The IES-612-51A supports standalone and daisychain switch modes.
10.2.1 Standalone Switch Mode
“Standalone switch mode” relates to the IES-612-51A’s operational behavior, not a standalone
network topology. The standalone switch mode allows either or both of the IES-612-51A’s
Ethernet ports to connect to the backbone Ethernet network. You can also connect one of the
IES-612-51A’s Ethernet ports to the Ethernet network and the other to another IES-612-51A
(see Figure 41 on page 98 for an example). When the IES-612-51A is in standalone mode, you
can use it in a network topology that uses loops (you should also enable RSTP). You can have
multiple IES-612-51A connected on the same network and set both of them to use standalone
mode in order to use them with a network topology that uses loops.
Standalone switch mode with port isolation enabled blocks communications between
subscriber ports on an individual IES-612-51A. However, one IES-612-51A’s subscribers can
communicate with another IES-612-51A’s subscribers if the two IES-612-51A’s Ethernet
ports are connected to each other (see Figure 41 on page 98 for an example). If you have
multiple IES-612-51A connected on the same network and set to standalone mode, they do not
all need to have the same port isolation setting.
