2H28-08R SmartSwitch 2208 User’s Guide 5-19
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.
For details on how to select the Operational Mode, refer to Section 5.7.9.
Com (Toggle)
Allows the user to enable or disable the COM port. The selection toggles
between ENABLED and DISABLED. The default is ENABLED. For
details about setting up the COM port, refer to Section 5.7.10.
Application (Toggle)

Power Conversion Smart Uninterruptible Power Supply (UPS).
The baud rate setting for LM is automatically sensed. For the UPS, the
baud rate is automatically set to 2400.
The default setting is LM. For details about how to configure the COM
port for various applications, refer to Section 5.7.10. See the caution
