Chapter 3 System Configuration 19
DSCP includes its own security measures that prohibit a compromised domain from
compromising other domains or the Service Processor.
The DSCP should only be configured when there are no domains running. If you
change the DSCP configuration while a domain is active, you have to power off the
domain before the Service Processor can communicate with it. Refer to Chapter 4 for
more information on domains.
In a typical DSCP configuration, you enter a network address and netmask using the
setdscp command. The system then configures the Service Processor IP address
and any domain IP addresses according to this formula: the Service Processor gets
an IP address that is the network address +1; and each domain gets an IP address
that is the Service Processor IP address, + the domain ID, +1. For example, if you
enter 10.1.1.0 for the network address, and 255.255.255.0 for the netmask, the
showdscp command displays output similar to the following:
This scenario minimizes the range of IP addresses needed for DSCP.
XSCF Network Interfaces
The XSCF network configurable settings include the IP address for the active Service
Processor, IP address for the standby Service Processor, gateway address, netmask,
and network route.
