After enabling the Switch to be a Commander Switch (CS), the Single IP Management folder will then contain four
added links to aid the user in configuring SIM through the web, including Topology, Firmware Upgrade,
Configuration Backup/Restore and Upload Log File.

This window will be used to configure and manage the Switch within the SIM group and requires Java script to

will render all SIM functions on the Switch inoperable.
Use the drop-down menu to enable or disable sending the trap.
Use the drop-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 Switch.
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.
Enter a Group Name in this textbox. This is optional, and only available when SIM State is
Enabled and Role State is Candidate. This name is used to segment switches into different
SIM groups.
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. The default value is 30 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. The default value is 100 seconds.
