xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual

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, then send it to the MS. After execution, the CS may receive a response packet
from the MS, which it will encode and send back to the administrator.
When a CS becomes a MS, it automatically becomes a member of the first SNMP community (include 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.
The Upgrade to v1.6
To better improve SIM management, the xStack DGS-3600 Series switches have been upgraded to version 1.6 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 Maintain 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.
This version will support multiple 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 – 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..
• Log – The switch now supports uploading MS log files to a TFTP server.
NOTE: For more details regarding improvements made in SIMv1.6, please refer to the
Single IP Management White Paper located on the D-Link website.
