TitleHow to kill the BCMDPC process responsible for high CPU utilization
Question
  • How to kill the“bcmDPC” process responsible for high CPU utilization?
Environment
  • Summit X460
  • Summit X440-G2
  • EXOS 15.3
  • EXOS 21.1.2.14 
  • EXOS 21.1.3.7
Answer
  • The bcmDPC is responsible for reporting messages to the shell.  Whenever there is a parity error in the L2/L3 table received this process reports this information.
  • These errors are continuously coming in therefore overloading the process and possibly causing the issue.
  • Unfortunately, we do not have a command to verify the parity error related to process “bcmDPC” is increasing or not.

The below two steps are implemented in order to kill the “bcmDPC” process:

  1. Rebooting the switch when you have a maintenance window is the simplest way to bring down the high CPU utilization by “bcmDPC” process.
  2. Clearing the forwarding database seems fixing this issue as well. The command is clear fdb?. The switch will have to re-learn all forwarding information which should be unnoticeable, but may cause short slowdown in traffic (depending on the number of FDB entries).
