NETWORK CONFIGURATION

Reordering multiple server ports for TCP/IP
If an IBM® Lotus® Domino™ server has multiple IBM® Lotus® Notes® network ports for TCP/IP, the order in which these ports are listed in the NOTES.INI file and the Server document affects how other servers and workstations connect to this server. The Ports setting in the NOTES.INI file determines which port a workstation or server tries first. In the absence of other settings that bind an NRPC, POP3, IMAP, SMTP, or LDAP service to an IP address, all of these services will try to use the port listed first in the NOTES.INI file.

Server-to-server communication

If you add a second Notes network port for TCP/IP in order to isolate server-to-server communication -- for example, a private network for cluster replication -- list this port first in the NOTES.INI file so that server-to-server traffic will tend to occur over this connection, thus decreasing the data flow on the port for the user network. To change the port order in the NOTES.INI file, use the Port Setup dialog box.

For more information, see the topic Reordering network ports on a server.

Note If you are setting up a private cluster network and do not list the server port first, you must add the setting Server_Cluster_Default_Port to the NOTES.INI file. The disadvantage of adding this setting is that if the server encounters a problem connecting over this port, it will not try another port, and replication will not occur.

Workstation-to-server communication

If a Domino server has a port for workstations to connect on -- for example, over a LAN -- and another port for servers to connect on -- for example, over a WAN -- list the workstation port first in the Server document so that users see only servers on the LAN when they choose File - Application - Open.

To reorder the ports in the Server document, click the Ports - Notes Network Ports tab, and edit the fields in the table.
