Topology - D-Link DES-3526 Manual

Change the SIM State to Enabled using the pull-down menu and click Apply. The window will then
refresh and the SIM Settings window will look like this:
The following parameters can be set:
Parameters Description
SIM State
Role State
Discovery Interval
Holdtime
Click Apply to implement the settings changed.
After enabling the Switch to be a Commander Switch (CS), the Single IP Management folder will
then contain three added links to aid the user in configuring SIM through the web, including
Topology, Firmware Upgrade and Configuration Backup/Restore.

Topology

The Topology window will be used to configure and manage the Switch within the SIM group and
requires Java script to function properly on your computer. The following message should appear the
first time the user clicks the Topology link in the Single IP Management folder.

Use the pull-down menu to either enable or disable the SIM state on the Switch. Dis-
abled will render all SIM functions on the Switch inoperable.
Use the pull-down menu to change the SIM role of the Switch. The two choices are:
Candidate - A Candidate Switch (CaS) is not the member of a SIM group but is
connected to a Commander Switch. This is the default setting for the SIM role of the
DES-3526.
Commander - Choosing this parameter will make the Switch a Commander Switch
(CS). The user may join other switches to this Switch, over Ethernet, to be part of its
SIM group. Choosing this option will also enable the Switch to be configured for SIM.
The user may set the discovery protocol interval, in seconds that the Switch will send
out discovery packets. Returning information to a Commander Switch will include
information about other switches connected to it. (Ex. MS, CaS). The user may set the
Discovery Interval from 30 to 90 seconds.
This parameter may be set for the time, in seconds; the Switch will hold information
sent to it from other switches, utilizing the Discovery Interval. The user may set the
hold time from 100 to 255 seconds.
