Switch Fabric Overview; Switch Fabric Link Monitoring - Dell Force10 C150 Configuration Manual

Switch Fabric overview

The switch fabric is formed through the installed RPMs and line cards via C-Series Switch Fabric (CSF)
ASICs.
Each RPM includes four CSFs, each of which provides eight Backplane Data (BDP) links, one link for
each line card slot. In total, an RPM provides 32 BDP links of forwarding capacity.
Each line card includes two CSFs. Six of the eight links on the CSFs are used as follows:
• Up to four ports—ports 1 to 4—connect to the Forwarding Processors (FP). These ports are referred to
as the Internal Dataplane (IDP) link.
• Ports 5-8 connect to the RPMs. These ports are referred to as the BDP links.

Switch Fabric link monitoring

FTOS Switch Manager (SWMGR) task monitors the BDP links on the RPM. This task also monitors the
overall state of the switch fabric and reports any changes via Syslog messages.
