In this example, after five minutes of “idleness” (no input or action), the
terminal “beeps” five times, the Local Management application
terminates the session, and the display returns to the Password screen. To

Module Uptime (Read-Only)
Displays the total time that the module has been operating.
Operational Mode (Selectable)
Used to set the 6H123-50 or 6H133-37 so it operates as an 802.1D switch
(802.1D SWITCHING), an IEEE 802.1Q switch (802.1Q SWITCHING),
or as a Cabletron Systems SecureFast switch (SECURE FAST VLAN).
In all three modes of operation, the 12 connections on each RJ21 port
(CONN1 – CONN4 on 6H123-50 or CONN1 – CONN3 on 6H133-37)
may be assigned individually to operate at 10 Mbps or 100 Mbps. The
connections that share either 10 Mbps or 100 Mbps operation reside on
one network (two networks per RJ21 port).
In the 802.1D SWITCHING mode, each of the networks are
automatically bridged to each other and to any Fast Ethernet Interface
Module in the 6H123-50 or HSIM port(s) in the 6H133-37.
In the 802.1Q SWITCHING mode, the switching function of the device
can be increased by creating and maintaining IEEE 802.1Q port based
Virtual LANs (VLANs).
In the SECURE FAST VLAN mode, the device acts as a SecureFast
switch. With the Cabletron Systems VLAN Manager software, the device
is able to increase its switching function by creating and maintaining
VLANs.
For details on how to select the Operational Mode, refer to Section 5.15.9 .
