Chapter 5: Local Management
5-42 DLE28-MA User’s Guide
Screen Refresh Time (Modifiable)
Contains the rate at which the screens are updated. This setting
determines how frequently (in seconds) information is updated on the
screen. To enter a new update time, refer to Section 5.15.7.
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 DLE28-MA to operate as an IEEE
802.1D switch (802.1D SWITCHING option), or an IEEE 802.1Q switch
(802.1Q SWITCHING 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 DLE28-MA are able to increase their
switching functionality by creating and maintaining IEEE port based
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
DLM6C-AA 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.
