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 Declarations are withdrawn by issuing a Leave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 SAM1316-22 supports standalone and daisychain switch modes.
10.2.1 Standalone Switch Mode
“Standalone switch mode” relates to the SAM1316-22’s operational behavior, not a
standalone network topology. The standalone switch mode allows either or both of
the SAM1316-22’s Ethernet ports to connect to the backbone Ethernet network.
You can also connect one of the SAM1316-22’s Ethernet ports to the Ethernet
network and the other to another SAM1316-22 (see
Figure 38 on page 82 for an
example). When the SAM1316-22 is in standalone mode, you can use it in a
network topology that uses loops (you should also enable RSTP). You can have
multiple SAM1316-22 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.
