In addition to standard manageability features such as LEDs, SNMP alarms and traps, and Syslogging, the
C-Series supports several diagnostic and debugging features that are crucial to isolating and resolving
support issues during the operations and maintenance phase.

Switch Fabric Overview
C-Series Debugging and
Diagnostics
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.
