show process cpu命令可自发显示 CPU 的当前情况。请注意,Cisco Catalyst 3850系列交换机使用四个内核,并且您会看到所有四个内核的CPU使用率: 3850-2#show processes cpu sorted | exclude 0.0 Core 0: CPU utilization for five seconds: 53%; one minute: 39%; five minutes: 41% Core 1: CPU utilization ...
Step 2: Determine the CPU Queue that Causes the High CPU Usage ConditionThe Cisco Catalyst 3850 Series Switch has a number of queues that cater to different types of packets (the FED maintains 32 RX CPU queues, which are queues that go directly to the CPU). It is important to monitor th...
We are getting high cpu on at least 2 of our 3850x Stacks. Spoke to TAC he noted: CSCuo14511 fed and stack-mgr causing High CPU on 3850 Suggesting to upgrade to 03.03.04SE Has anyone seen this and solved it without an upgrade. Thanks, Tom
show processes cpu platform sorted命令用於顯示來自Linux核心的進程利用率情況。從輸出中可以看到FED進程較高,這是由於傳入IOSd進程的ARP請求所致: Switch#show processes cpu platform sortedCPU utilization for five seconds: 38%, one minute: 38%, five minutes: 40% Core 0: CPU utilizat...
