About this task

The following is an example of a list of TCP/IP options that you can use to set up your system.
commmethod        tcpip
  tcpport         1500
  tcpwindowsize   0
  tcpnodelay      yes
Tip: You can use TCP/IP Version 4, Version 6, or both.
TCPPORT
The server port address for TCP/IP and SSL communication. The default value is 1500.
Linux operating systemsAIX operating systemsTCPWINDOWSIZE
Linux operating systemsAIX operating systemsSpecifies the size of the TCP/IP buffer that is used when sending or receiving data. The window size that is used in a session is the smaller of the server and client window sizes. Larger window sizes use additional memory but can improve performance.

You can specify an integer from 0 to 2048. To use the default window size for the operating system, specify 0.

Windows operating systemsTCPWINDOWSIZE
Windows operating systemsSpecifies the size of the TCP/IP buffer that is used when sending or receiving data. The window size that is used in a session is the smaller of the server and client window sizes. Larger window sizes use additional memory but can improve performance.

To use the default window size for the operating system, specify 0.

TCPNODELAY
Specifies whether or not the server sends small messages or lets TCP/IP buffer the messages. Sending small messages can improve throughput but increases the number of packets sent over the network. Specify YES to send small messages or NO to let TCP/IP buffer them. The default is YES.
TCPADMINPORT
Specifies the port number on which the server TCP/IP communication driver is to wait for TCP/IP or SSL-enabled communication requests other than client sessions. The default is the value of TCPPORT.
SSLTCPPORT
(SSL-only) Specifies the Secure Sockets Layer (SSL) port number on which the server TCP/IP communication driver waits for requests for SSL-enabled sessions for the command-line backup-archive client and the command-line administrative client.
SSLTCPADMINPORT
(SSL-only) Specifies the port address on which the server TCP/IP communication driver waits for requests for SSL-enabled sessions for the command-line administrative client.
