Configuring HAFM Through a Firewall
215 HA-Fabric Manager User Guide
Configuring TCP Port Numbers to Allow Firewall Access
This section provides details about configuring TCP port numbers for RMI
Servers and Registries to allow HAFM Client and Server application to function
across firewalls.
HAFM Function with RMI at TCP Port Level
The RMI protocol lies between the HAFM application and the TCP/IP layer, as
shown in the following table.
As shown in Figure 110 , the HAFM appliance and Clients communicate with
each other through the RMI Server. This is a full-duplex function. However,
before the RMI Server on the HAFM Client can communicate with the RMI
Server on the HAFM appliance, it must know the TCP port number of the RMI
Server. The function of the RMI registry is to communicate this TCP port number
to the HAFM Client. Once this is done successfully, communication can take
place between the RMI Server on the HAFM appliance and the HAFM Client.
(The HAFM appliance obtains the TCP port number of the RMI Server on the
Client during initial communications.)
