• The CaS can be configured through the CS to become a MS.
After configuring one Switch to operate as the CS of a SIM group, additional Switches may join the group by manually
configuring the Switch to be a MS. The CS will then serve as the in band entry point for access to the MS. The CS’s IP
address will become the path to all MS’s of the group and the CS’s Administrator’s password, and/or authentication
will control access to all MS’s of the SIM group.
With SIM enabled, the applications in the CS will redirect the packet instead of executing the packets. The
applications will decode the packet from the administrator, modify some data, and then send it to the MS. After
execution, the CS may receive a response packet from the MS, which it will encode and send it back to the
administrator.
When a CaS becomes a MS, it automatically becomes a member of the first SNMP community (includes read/write
and read only) to which the CS belongs. However, if a MS has its own IP address, it can belong to SNMP
communities to which other Switches in the group, including the CS, do not belong.
Upgrade to v1.61
To better improve SIM management, the Switches have been upgraded to version 1.61 in this release. Many
improvements have been made, including 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.
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.
This version will support Switch upload and downloads for firmware, configuration files and log files, as follows:
• Firmware - The Switch now supports MS firmware downloads from a TFTP server.
• Configuration Files - The 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.
• Log - The Switch now supports uploading MS log files to a TFTP server.
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
This window is used to display and configure the SIM settings. The Switch is set as a Candidate (CaS) as the factory
default configuration and Single IP Management is disabled.
