Appendix B: CC-SG and Network Configuration
CC-SG and Raritan Devices
A main role of CC-SG is to manage and control Raritan devices, such as
Dominion KX II. Typically, CC-SG communicates with these devices over
a TCP/IP network (local, WAN, or VPN) and both TCP and UDP
protocols are used as follows:
RDM protocol
RC4/AES-128/AES-2
56 encrypted
CC-SG to Dominion KXII in
Direct Mode
CC-SG Clustering
When the optional CC-SG clustering feature is used, the following ports
must be available for the inter-connecting sub-networks. If the optional
clustering feature is not used, none of these ports has to be open.
Each CC-SG in the cluster may be on a separate LAN. However, the
inter-connection between the units should be very reliable and not prone
to periods of congestion.
Several TCP/IP connections are maintained and initiated by the
Primary to the Backup in a CC-SG cluster. These connections may be
idle for extended periods of time, but they are necessary for the
cluster to operate.
Ensure that all CC-SG to CC-SG cluster connections over VPN or
firewalls do not time out or become blocked. Timing out these
connections will cause the cluster to fail.
