Specifying a Fixed Local Port Number for the NetwrkCIC Process
In an ICM-to-ICM Gateway implementation, the NetwrkCIC process is a part of
the Client ICM Router installation that manages the ICM Gateway. By default, the
IP port used in the NetwrkCIC process for the public network communication to
the Server ICM INCRP NIC process is selected dynamically at runtime.

IP port used in the NetwrkCIC process for the public network communication to
the Server ICM INCRP NIC process is selected dynamically at runtime.
ICM processes use IP port numbers between 39000 and 50000. Use the following
formula to obtain the number for side A of a duplexed system
formula to obtain the number for side A of a duplexed system
Port number = 40000 + (i * 40) + 33
where i is the instance number of an ICM instance. To find out the instance
number, run the local setup program, select an instance and click the edit button.
The “Edit Instance” dialog box will display the instance number.

The “Edit Instance” dialog box will display the instance number.
For instance number 0, the port number will be 40033.
For side B, the port number is obtained by adding 1000 to the above number. This
formula is intended to be stable. However, there is no guarantee that the formula
will not change.

This dynamic port allocation is an issue for some ICM customers. You can
optionally modify the NetwrkCIC process to use a specific port number. If a
specific port number is provided in the registry of the Client ICM machine, the
NetwrkCIC process will instead bind to that port number when communicating
with the server INCRP NIC process.

To specify this port number, add the following registry entry on the Client ICM
machine:
machine:
HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\ICM\<instance
name>\Router[A,B]\CIC\CurrentVersion\Configuration\CIC Public LAN IP
Port
Specify this entry as a DWORD type.
This registry entry is not managed by the ICM Setup program. Therefore if you
upgrade ICM software later, you must add the registry entry again.

If you change the port number while the NetwrkCIC process is running, you must
restart the ICM router service for it to take effect.
