To better improve SIM management, the DES-3810-28 Series switches have been upgraded to version 1.61 in this
release. Many improvements have been made, including:
1. The Commander Switch (CS) now has the capability to automatically rediscover member switches that have
left the SIM group, either through a reboot or web malfunction. This feature is accomplished through the use
of Discover packets and Maintenance packets that previously set SIM members will emit after a reboot. Once
a MS has had its MAC address and password saved to the CS's database, if a reboot occurs in the MS, the
CS will keep this MS information in its database and when a MS has been rediscovered, it will add the MS
back into the SIM tree automatically. No configuration will be necessary to rediscover these switches.
There are some instances where pre-saved MS switches cannot be rediscovered. For example, if the Switch is still
powered down, if it has become the member of another group, or if it has been configured to be a Commander Switch,
the rediscovery process cannot occur.
2. The topology map now includes new features for connections that are a member of a port trunking group. It
will display the speed and number of Ethernet connections creating this port trunk group, as shown in the
adjacent picture.
3. This version will support switch upload and
downloads for firmware, configuration files and log
files, as follows:
a. Firmware – The switch now supports MS
firmware downloads from a TFTP server.
b. Configuration Files – This switch now
supports downloading and uploading of
configuration files both to (for configuration
restoration) and from (for configuration
backup) MS's, using a TFTP server.
c. Log – The Switch now supports uploading
MS log files to a TFTP server.
4. The user may zoom in and zoom out when utilizing
the topology window to get a better, more defined
view of the configurations.
Single IP Settings
The Switch is set as a Candidate (CaS) as the factory default configuration and Single IP Management is disabled.
To view the following window, click Management > Single IP Management > Single IP Settings, as shown below:

Description
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.
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
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.
