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 Declarations are withdrawn by issuing a Leave message.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
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
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.
