Chapter 5: Local Management
5-42 6E123-50 and 6E133-49 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 6E123-50 and 6E133-49 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 6E123-50 and 6E133-49 are able to
increase their switching functionality by creating and maintaining IEEE
port based VLANs.
When the operational mode is set to SECURE FAST VLAN, the
6E123-50 and 6E133-49 act as SecureFast switches. With the Cabletron
Systems VLAN Manager software, the modules are able to increase their
switching functionality by creating and maintaining Virtual LANs
(VLANs).
For details on how to select the Operational Mode, refer to Section 5.15.9 .
Management Mode (Toggle)
This field toggles between DISTRIBUTED and STAND ALONE.
In DISTRIBUTED mode, Local Management is entered via the 6C105
password screen, and all chassis configuration screens are available to the
user. All other modules installed in the chassis that are set for distributed
management may also be accessed via a connection to a single COM port
on one of the modules.
