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 deregister 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 Declarations are withdrawn by issuing a Leave message.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.
