Management Plane high utlization

L3 Networker

Hi guys,


Im having a query regarding Packet buffer protection where after enabling it i can find that management plane cpu utilization reached from 7 to 80% im not sure what could cause it.


So can some one refer me when does management plane reaches the high utilization and does enabling packet buffer protection cause this issue?

Hi @Vijaygvasan ,


I can't really say if enabling this option will have that much of an impact on the mgmt CPU. 

Can you disable it again to confirm if your mgmt CPU normalizes after that ?


There can be many reasons why your mgmt CPU is high. 

There are plenty of discussions on the topic and several ways to reduce it as well.


The following blogs are a good place to start if you're looking to decrease the MP load:
