    Description

      Hello after update Junos from 12.3R12.4 to 15.1R7.9 on mixed virtual chassis consisted of Juniper EX4500 and EX4200 the is a very high load of the routing engine.

      According to https://supportportal.juniper.net/s/article/EX-Troubleshooting-and-resolving-high-CPU-utilization-on-EX4300?language=en_US I discovered that the process causing the problem is mib2d - which means SNMP.
