DSCP Network Between a Service Processor and a
Domain
The Domain to Service Processor Communications Protocol (DSCP) service provides
a secure TCP/IP- and PPP-based communication link between the Service Processor
and each domain. Without this link, the Service Processor cannot communicate with
the domains.
The Service Processor requires one IP address dedicated to the DSCP service on its
side of the link, and one IP address on each domain’s side of the link. The DSCP
service is a point-to-point link between the Service Processor and each domain.
FIGURE 3-1 illustrates this relationship.

FIGURE 3-1 Relationship of the Service Processor and the DSCP Network to the Domains
DSCP service is not configured by default. You configure and use the service by
specifying IP addresses for the Service Processor and the domains. The IP addresses
should be nonroutable addresses on the network.
The setdscp command provides an interactive mode that displays a prompt for
each DSCP setting you can configure:
The network address to be used by the DSCP network for IP addresses
The netmask for the DSCP network
The Service Processor IP address
An IP address for each domain
In a system with redundant Service Processors, the standby Service Processor does
not communicate with the domains. In the event of a failover, the newly active
Service Processor assumes the IP address of the failed-over Service Processor.
