Chapter 2 Setting Up XSCF 2-19
In systems with two XSCF Units, the two XSCF Units are connected by system internal
ports, which are the RS-232C (serial) ports and the LAN ports. Each XSCF Unit monitors
the status of the other one and they exchange system information through these
communication paths. When the system is initially set up, the user must specify the IP
address for internal LAN routes.
In the M8000/M9000 servers, up to 33 IP addresses are usually specified: four for
XSCF-LAN ports, two for the ISN, two for the Takeover IP addresses, and up to 25 for
DSCP on both the XSCF and domain sides. In the M4000/M5000 servers, up to seven IP
addresses are usually specified: two for XSCF-LAN ports and up to five for DSCP on both
the XSCF and domain sides. In the M3000 server, up to four IP addresses are usually
specified: two for XSCF-LAN ports and two for DSCP on both the XSCF and domain sides.
Caution – IMPORTANT If the XSCF Unit is redundant, issue the commands to setup all
XSCF on only the Active XSCF Unit. The command need not be executed on both (Active
and Standby) XSCF Units. The XSCF setting cannot be performed on the standby side.
XSCF network interface configuration
The XSCF network interface includes the following.
LAN (XSCF-LAN) for users to access to XSCF
LAN (ISN) for the communication between XSCF Units (M8000/M9000 servers only)
LAN (DSCP) for the communication between XSCF and each domain
Add/delete DNS Add or delete the IP address of a name server
and the domain name of a search path.
Up to three name servers can be registered.
Names can be solved in the order specified.
Up to five search paths can be registered.

If the DNS
connection is
necessary, this setting
is done.
