Normal Conditions with High CPU Utilization. A vulnerability in the IP Version 4 (IPv4) processing code of Cisco IOS XE Software running on Cisco Catalyst 3850 and Cisco Catalyst 3650 Series Switches could allow an unauthenticated, remote attacker to cause high CPU utilization, traceback messages, or a reload of an affected device that leads to a denial of service (DoS). Linux will schedule a process (remember IOSd is a single process from the Linux perspective) on a CPU core based on a number of different factors, including utilization of the other cores at any given time. 06. 65% 0 SNMP ENGINEThe stack cable could need to be replaced.
