To make the IP address redundant, specify the same subnet address to the LAN port
of XSCFU#0 side and to the LAN port of XSCFU#1 side which share the same LAN
port number. Also, The IP address of XSCF-LAN#0 and the IP address of
XSCF-LAN#1 must be specified in different subnet addresses.
2. Perform the following setting to specify the takeover IP address in a redundant
XSCF configuration.
When you specify the takeover IP address, in case the XSCF failover occurred, the
control switching between the active side and the standby side performed, and then
the IP address will be taken over. The user who accesses the takeover IP address can
always connect to the active side XSCF, without being aware of the XSCF switching.
Sets IP address respectively of XSCF-LAN#0 and XSCF-LAN#1. In addition, on each
LAN port of XSCF-LAN#0 and XSCF-LAN#1 in the redundant system, specify the
takeover IP address one by one (see "3" and "6" in
setnetwork(8).)
3. In a redundant XSCF configuration, specify the two IP addresses of ISN.
Since ISN is a network for the communication between the redundant XSCF Units, it
is necessary to specify the IP address. The ISN address has been set up with the
default value (see
TABLE 2-2
If the IP address of XSCF-LAN conflicts with the default subnet address of ISN, you
must specify the IP address of ISN (see "7" and "8" in
addresses must be in the same network subnet. Users cannot access this network.
(See shownetwork(8), setnetwork(8).)
4. Specify the DSCP address.
After configured the domain (see
page
2-146), specify the DSCP address.
Specify one DSCP IP address in the XSCF-side, and one for each of the domains (See
"9," "10" or later in
FIGURE 2-1
address which is used in all of the DSCP links. In this case, the IP addresses used by
the XSCF and each domain-specific DSCP link are automatically selected from
within the range of addresses indicated by the DSCP network address.
All DSCP addresses must be in the same network subnet. Since the DSCP is the
network for the communication between domain and XSCF, users can't access to this
network. When you changed the DSCP address, you must reset XSCF by using the
rebootxscf(8) command before domain start up, in order to maintain the
consistency between XSCF and the domain. After XSCF resetting, the domain restart
is required. (See showdscp(8), setdscp(8).)
).

). By specifying the option, you can specify one DSCP
