If the Switch Administrator wishes to configure the Switch as a Commander Switch (CS), select commander from the Role State
field and click Apply. The window will change once again to look like this:
The following parameters can be set:
Parameters Description
SIM State Use the pull down menu to either enable or disable the SIM state on the Switch. Disabled will
render all SIM functions on the Switch inoperable.
Role State Use the pull down menu to change the SIM role of the Switch. The two choices are:
Discovery The user may set the discovery protocol interval, in seconds that the Switch will send out
Interval 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.
Holdtime 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.
Group Name The administrator may set the name of the SIM group here, of which this Switch has been
nominated Commander. The default name for the Group is default.
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 four added links
to aid the user in configuring SIM through the web, including Topology, Firmware Upgrade and Configuration
Backup/Restore and Upload Log File.
