General Configuration Screen

Operational Mode (Selectable)

Allows the user to set the 2H28-08R to operate as a traditional switch (802.1D SWITCHING option), a prestandard IEEE 802.1Q, (802.1Q SWITCHING option) or as a Cabletron Systems SecureFast switch (SECURE FAST VLAN option).

In 802.1D SWITCHING mode, the 6 fixed ports located on the front panel and any installed Fast Ethernet Interface Modules are bridged to each other.

In 802.1Q SWITCHING mode, the 2H28-08R is able to increase its switching functionality by creating and maintaining port based VLANs. When this operation is selected, 802.1Q VLAN CONFIGURATION will appear as a menu item on the Device Specific Configuration Menu. If the device is not set to 802.1Q, the menu item will not appear as an option.

When the operational mode is set to SECURE FAST VLAN, the

2H28-08R acts as a SecureFast switch. With the Cabletron Systems VLAN Manager software, the 2H28-08R is able to increase its switching functionality by creating and maintaining VLANs. Certain options that are available in other modes in the menu screens will not be available with the SecureFast option.
