/tc:tc-config/servers/server/tsa-group-port
This section lets you set the port that the Terracotta server uses to communicate with other Terracotta servers.
The default value of "tsa-group-port" is 9530. If tsa-port is set to a value other than the default 9510, this port defaults to the value of the tsa-port plus 20.
Here is a sample configuration snippet:
<tsa-group-port>9530</tsa-group-port>
