b. If report packets from the CS to the MS time out.
5. The user can manually configure a CaS to become a CS
6. 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, 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 (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 v1.6.1
To better improve SIM management, the xStack DGS/DXS-3300 series switches have been upgraded to version 1.6.1 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 multiple MS firmware downloads from a TFTP server.
Configuration Files – This switch now supports multiple 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 multiple MS log files to a TFTP server.
This SIM version now supports encryption and decryption of SIM packets for added security between SIM enabled switches
within the same SIM group.
The D-Link Single IP Management commands in the Command Line Interface (CLI) are listed (along with the appropriate
parameters) in the following table.
