Troubleshoot Common High CPU Utilization Problems This section covers some of the common high CPU utilization problems on the Catalyst 3750 Switch. http://justjoomla.net/high-cpu/w3wp-exe-high-cpu-iis.html

Without CEF enabled, the SNMP agent responds with information from the Routing Information Base (RIB), which must be sorted into lexicographical order causing high-CPU. Cisco IOS learns about routes from routing protocols—such as BGP, RIP, OSPF, EIGRP, and IS-IS—and from statically configured routes. The CPU utilization history shows when the CPU is consistently receiving network packets, but it does not show the cause.
This is why even in the simplest of deployments, the switch never reports 0% CPU utilization. Queue 15 corresponds to cpu heartbeat, and so on. It spiked to 87 percent within the past hour. Snmp-3-cpuhog There are two versions of each template: a desktop template and an aggregator template.
These scenarios can cause heavy CPU usage by the SNMP engine system process: Multiple servers simultaneously performing an SNMP query. Snmp Engine High Cpu 3750 System Processes and Punted Packets On a Layer 3 switch, when the IP route is not known, the switch hardware punts (sends) IP packets to the CPU for IP routing. A managed device is a node that has an SNMP agent and resides on a managed network. If the interrupt percentage is too high relative to the total CPU utilization percentage, the CPU utilization problem is caused by receiving too many packets from system hardware.
All of the devices used in this document started with a cleared (default) configuration. Snmp-server View Cutdown Router(config)#snmp-server view

Is there a show command that will display what OID being polled is causing so much CPU to be used? Identifying Network Packets Received by the CPU These techniques to determine the type of packets being sent to CPU can complement each other or can be used individually. Snmp Engine High Cpu Enter the command multiple times to review active queue discards. Cisco Router High Cpu router(config)# snmp-server view cutdown 18.104.22.168.22.214.171.124 excluded router(config)# snmp-server view cutdown 126.96.36.199.188.8.131.52 excluded router(config)# snmp-server view cutdown 184.108.40.206.2.1.3 excluded Exclude CPU Intensive snmpUsmMIB, snmpVacmMIB,snmpCommunityMIB These are good to disable for Security reasons
Monitoring IP Traffic Counts The switch counts all IP packet types received by the CPU. navigate here Switch# show platform ip unicast statistics Global Stats: HWFwdLoc:0 HWFwdSec:0 UnRes:0 UnSup:0 NoAdj:0 EncapFail:0 CPUAdj:1344291253 Null:0 Drop:0 Prev Global Stats: HWFwdLoc:0 HWFwdSec:0 UnRes:0 UnSup:0 NoAdj:0 EncapFail:0 CPUAdj:1344291253 Null:0 Drop:0 if so It would be much appreciated. Therefore, while CPU spikes occur in this scenario, they should not affect performance. Show Snmp Stats Oid
Route summary is enabled by default for RIP and EIGRP and disabled by default for OSPF. Therefore, for each SNMP request the router receives, the hash table must be sorted lexicographically before a SNMP response PDU can be built. We recommend that you use the switch console for debugging CPU utilization issues. http://justjoomla.net/high-cpu/wuauserv-high-cpu.html interchange it bro..
Configure the router to respond with a complete message as soon as it receives the start of a request for the route table, as follows: snmp-server view cutdown iso included !--- Hulc Led Process Sometimes we may find that some MIB are just responding slowly due to other issues or even because of a bug, or that the client is polling the server in a Not the answer you're looking for?
In the next example, the interrupt percentage is low compared to the CPU utilization percentage (5 percent compared to 82 percent).
These devices can be routers and access server, switches and bridges, hubs, computer hosts, or printers. The following example shows the output of the show process cpu command. To see if the TCAM is full, enter the show platform tcam utilization privileged EXEC command. Cisco Router High Cpu Interrupts A full TCAM and increasing sw forwarding counts from the show controllers cpu-interface command output means that punted packets are causing high CPU utilization.
To allocate more TCAM resources to indirect Layer 3 routes, you must reduce some other TCAM resources. You can identify packets sent to the CPU by enabling debugging for a queue. Punted packets are handled at the interrupt level and can cause the CPU to become too busy. http://justjoomla.net/high-cpu/xorg-using-high-cpu.html An interrupt percentage over 10 percent should be investigated.
Because the switch hardware sees the CPU receive-queue dropped packets as sent to the supervisor, the dropped packets are called Supervisor TxQueue Drop Statistics in the command output. It is recommended that these objects be exlcluded from view on any device which can be accessed by public users. It is normal for the CPU to go high due to this SNMP ENGINE process. Even for this, packets cannot be switched with hardware.
This can range anything from 15% to 40%. Determine if the TCAM is full. This is typically selected for a Layer 2 switch. Graphlex 4x5 Lens Hood and Filters - How Do They Mount?
Examine the output for information about the source, including the VLAN (200) and source MAC address (0000.0300.0101) of this packet (shown in bold text). *Mar 2 22:48:16.947: ICMP-Q:Dropped Throttle timer not i currently have a support case open to see if there is a bug or what is causing this process to hang like that...Switch# show process cpuRealtime Statistics:Load Average: One minute: Select an appropriate SDM template that provides maximum system usage for the feature used. Policing can deny ingress traffic, limit it to a specific bits-per-second rate, or permit some traffic while limiting other traffic.
I've broken my new MacBook Pro (with touchbar) like this, do I have to repair it? Are they all on the same supervisor and IOS version? The outcome of these configurations is that the router no longer returns either the ARP table or the IP route table when queried. Beginning in privileged EXEC mode, follow these steps to prepare for debugging the CPU queue: Command Purpose Step 1 configure terminal Enter global configuration mode.
