Chapter 5: Local Management
5-42 6H122-08 User’s Guide
Screen Lockout Time (Modifiable)
Contains the maximum number of minutes that the Local Management
application displays a module’s screen while awaiting input or action
from a user. For example, if the number 5 is entered in this field, the user
has up to five minutes to respond to each of the specified module’s Local
Management screens. 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 enter a new lockout time, refer to Section 5.15.8.
Module Uptime (Read-Only)
Displays the total time that the module has been operating.
Operational Mode (Selectable)
This field allows the user to set the 6H122-08 to operate as an IEEE
802.1D switch (802.1D SWITCHING option), an IEEE 802.1Q switch
(802.1Q SWITCHING option), or as a Cabletron Systems SecureFast
switch (SECURE FAST VLAN option).
In 802.1D SWITCHING mode, the 24 ports located on the front panel,
and each Fast Ethernet Interface Module, and HSIM port(s) are bridged to
each other.
In 802.1Q SWITCHING mode, the 6H122-08 is able to increase its
switching functionality by creating and maintaining IEEE port based
VLANs.
When the operational mode is set to SECURE FAST VLAN, the
6H122-08 acts as a SecureFast switch. With the Cabletron Systems
VLAN Manager software, the module is able to increase its switching
functionality by creating and maintaining Virtual LANs (VLANs).
For details on how to select the Operational Mode, refer to Section 5.15.9.
