Note – In systems with two XSCF Units (the high-end systems), 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.
Note – In the high-end systems, 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 midrange system, 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.
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 (high-end systems only)
■
LAN (DSCP) for the communication between XSCF and each domain
