3.9.3 XSCF Network Interface Configuration


3.9.3 XSCF Network Interface Configuration
This section describes the following XSCF network interfaces:
  1. The system control network that provides users with access to the XSCF (XSCF-LAN)
  2. Link network for communication between XSCFs (SSCP) (in a system with multiple XSCFs)
With a system consisting of only one SPARC M12/M10, two IP addresses are set for XSCF-LAN in order to access the XSCF. The XSCF-LAN can use only one LAN port.
With SPARC M12-2S systems consisting of 4 chassis or SPARC M10-4S systems consisting of 4 chassis that are directly connected, 4 IP addresses are set for XSCF-LAN, 2 IP addresses are set as takeover IP addresses, and 10 IP addresses are set for SSCP, for a total of 16 IP addresses.
With SPARC M12-2S systems consisting of 16 chassis or SPARC M10-4S systems consisting of 16 chassis that are connected by 4 crossbar boxes, 4 IP addresses are set for XSCF-LAN, 2 IP addresses are set as takeover IP addresses, and 44 IP addresses are set for SSCP, for a total of 50 IP addresses.
Note - If the system has multiple XSCFs, the XSCFs cannot be configured from the standby XSCF. Commands for configuring all the XSCFs are executed only from the master XSCF.
Figure 3-4 shows the necessary network interfaces for configuring the XSCF network for the SPARC M12-2S or SPARC M10-4S system in the 4BB configuration, with chassis directly interconnected.

Figure 3-5 shows an example of the necessary network interfaces for configuring the XSCF network for the SPARC M12-2S or SPARC M10-4S system with crossbar boxes.
