1.3.2 XSCF-LAN Port Numbers and Functions, and Firewall


1.3.2 XSCF-LAN Port Numbers and Functions, and Firewall
Table 1-1 lists the port numbers used with the XSCF-LAN ports and the functions used by the XSCF. To protect the XSCF against unauthorized access and attacks when it is connected to an external network, we recommend configuring a firewall. If you install a firewall, you need to permit packets to pass through a port as required.

*1 Each symbol and number in parentheses has the following meaning:
Symbol ->: Denotes the direction from left to right. <->: Denotes the direction from either left to right or right to left.
Number in parentheses: Connection port number For a connection to an external network, the port number of the network can be changed on the XSCF. For details, see the section of the respective function in this document. For a connection to remote storage, the port number of the storage is fixed (3260).

*2 The ASR function is a remote maintenance service that uses the Oracle Auto Service Request software provided by Oracle Corporation. For details of the ASR function, see the Oracle Auto Service Request Installation and Operations Guide for the version of the software that you are using.
