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 xStack
®
DGS-3600 series switches may join
the group by either an automatic method or 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, 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.
