3.9.7 Flow of Configuring the XSCF Network
This section describes the procedure for configuring the XSCF network. References to detailed procedures are shown in the respective steps.
  1. Set an Ethernet (XSCF-LAN) IP address (physical IP address).
    Two XSCF-LAN ports can be used, depending on the network configuration.
    In systems with one XSCF, set either or both of the following IP addresses:
    - XSCF-LAN#0 of BB#00 (master XSCF)

    - XSCF-LAN#1 of BB#00 (master XSCF)

    In systems with multiple XSCFs, first set each XSCF-LAN IP address on the master XSCF side, and then set the XSCF-LAN IP address on the standby XSCF (see shownetwork(8), setnetwork(8), and 3.9.8).
    To be able to connect either XSCF in case of XSCF failover, set the same network address for the LAN ports with the same number on each XSCF.
    Different network addresses must be set for the IP addresses of XSCF-LAN#0 and XSCF-LAN#1.
  2. If the system has multiple XSCFs, set the takeover IP address (virtual IP address).
    The setting of the takeover IP address enables takeover of the IP address after switching of the master and standby sides in cases of XSCF failover. Users can always connect to the master XSCF by accessing the takeover IP address, with no need to pay attention to XSCF switching.
    After setting the respective IP addresses of XSCF-LAN#0 and XSCF-LAN#1, set one takeover IP address for the respective LAN ports of XSCF-LAN#0 and XSCF-LAN#1, which are redundant (see shownetwork(8), setnetwork(8), and 3.9.9).
  3. If the system has multiple XSCFs, specify SSCP IP addresses.
    SSCP is used in networks for communication between duplicated XSCFs, so the IP address settings are necessary. The value of the SSCP IP address was set beforehand at factory shipment (see Table 3-21 and Table 3-22).
    If the XSCF-LAN IP address settings conflict with the SSCP default network addresses, the SSCP IP addresses need to be set again. The SSCP IP addresses must be addresses within the same network in the same group or different network addresses outside of the group. For details on subnets, see "3.9.4  Understanding Network Group Subnets." Users cannot access the SSCP network (see showsscp(8), setsscp(8), and 3.9.10).
  1. Set the host name, routing, and DNS.
    In the systems with multiple XSCFs, first set the host name and routing on the master XSCF side, and then set them on the standby XSCF side (see showhostname(8), sethostname(8), showroute(8), setroute(8), shownameserver(8), setnameserver(8), 3.9.11, 3.9.12, and 3.9.13). 
  2. Set IP packet filtering rules.
    Set IP packet filtering rules for the XSCF-LAN (see showpacketfilters(8), setpacketfilters(8), and 3.9.14).
    For the settings for connecting remote storage to a slave XSCF, see "4.6.10  Configuring the XSCF-LAN Used with Remote Storage."
  3. Apply the network settings.
    To complete configuration of the network, settings must be reflected and the XSCF must be rebooted. The XSCF reboot disconnects the XSCF session, so log in again (see applynetwork(8), rebootxscf(8), and 3.9.15).
Note - If an XSCF reboot or failover occurs during execution of a setting command involving all the XSCFs, configuration may not complete successfully. Log in to the master XSCF again, and check whether the settings are correct. If they are incorrect, make the settings again.
