This identification enables you to debug the high CPU utilization problems. Review the syslog for reports of a failed power controller. After every 60 seconds an average is calculated from the collected data and stored as a data point in the 60 minute graph. Because of this, it is normal to see low free memory with the Fast memory pool. %SNMP-4-HIGHCPU: Process exceeds [dec]ms threshold ([dec]ms IOS quantum) for [chars] of [chars]--result [chars] The CPU http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/software/troubleshooting/cpu_util.html
To see a list of available SDM templates for your switch, enter the show sdm templates all privileged EXEC command. rpf fail—A queue for reverse path forwarding failures. Use the output from the show controllers cpu-interface privileged EXEC command to learn which queues to start debugging first.
This section reviews the commands that an administrator uses in order to narrow down the problem of high CPU utilization. Components Used This document is not restricted to specific software and hardware versions. Remember that this process is a background process. Hulc Led Process High Cpu This activity indicates that the CPU is busy as it processes packets destined to it.
Host Learning The Catalyst 4500 learns the MAC addresses of various hosts, if the MAC address is not already in the MAC address table. Show Memory Usage Cisco Used by Cisco system processes to communicate across the stack. For example, if the spanning-tree topology changes, the switch generates Topology Change Notifications (TCNs). see it here Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the
Table 3– TCAM Capacity on Catalyst 4500 Supervisor Engines/Switches Product Feature TCAM (per Direction) QoS TCAM (per Direction) Supervisor Engine II+/II+TS 8192 entries with 1024 masks 8192 entries with 1024 masks Ip Input High Cpu For more details, refer to the description of the service timestamps global configuration command. All subsequent packets will be fast switched, unless fast switching is explicitly disabled on the outgoing interface. If the CPUAdj value increments rapidly, packets are being punted from switch hardware.
With only this information, you know that the process of IP packets expends a sizable portion of the CPU. try this The output of the show platform health command confirms the use of the CPU in order to process CPU-bound packets. Command To Check Cpu Utilization In Cisco Router When the CPU interrupt percentage is high compared to the overall CPU utilization percentage, enter the show processes cpu sorted 5sec privileged EXEC c ommand to determine the most active system Cisco Router High Cpu Interrupts To view the number of the number of route entries used by each routing protocol, enter the show ip route summary privileged EXEC command.
You can also collect data using HTTP or SNMP. check over here Switch#show processes cpu CPU utilization for five seconds: 74%/1%; one minute: 73%; five minutes: 50% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 1 4 198 20 0.00% 0.00% 0.00% See More 1 2 3 4 5 Overall Rating: 0 (0 ratings) Log in or register to post comments bvsnarayana03 Tue, 05/20/2008 - 21:24 usually we check the avg utilisation (#), Spanning tree reconverges in the Layer 2 network. How To Check Bandwidth Utilization On Cisco Router
The issue of TCNs reduces the aging time to 15 seconds in PVST+ mode. but it makes more sense to me to have the most recent data on the right. Switch#show platform cpu packet statistics !--- Output suppressed. his comment is here Use the access list counters as a way to keep track of ACL hits.
Bcoz if your device is touching max util for most of the time than you definitely need to think about it. Cisco Fed Process I suspect the 10% value you note from the graph display of the right most graphic symbols is due to compression of white space. Step 1: Check for the Cisco IOS process with the show processes cpu command.
High CPU due to Software Encryption When there is no hardware encryption module installed in the device, then all encrypted traffic coming through the device will have to be encrypted by The output of the show platform health command confirms the use of the CPU in order to process CPU-bound packets. Issue the show platform health command. Cat4k Mgmt Lopri High Cpu Caution:Make this age-out change only after careful consideration.
Use to help determine if additional TCAM resources are needed for IP routing. 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 Figure 1 shows these queues. http://qaisoftware.com/high-cpu/cpu-usage-100-svchost.html In order to be able to better read and understand debugs, the datetime and millisecond timestamps should be enabled.
The move-the-problem method is an obvious candidate to approach suspected hardware problems, but this method works well only if the problem is strictly due to a broken piece of hardware. Step 1: Check for the Cisco IOS process with the show processes cpu command. For information about the CPU SPAN, see the Tool 1: Monitor the CPU Traffic with SPAN—Cisco IOS Software Release 12.1(19)EW and Later section of this document.

Get Access Questions & Answers ? On Cisco 7200 and Cisco 7500 Series Routers, use the scheduler allocate 3000 1000 command. Privacy Reply Processing your reply... 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.

CPU & Memory of a Cisco device are not defined in RFC 1213 mib. Use this UNIX script and, based on the first findings, modify the script to collect data needed for further investigation of the issue. Doherty Thu, 05/22/2008 - 11:15 Rick, correct me if I'm mistaken, but don't all three CPU history graphs show most recent data starting at the left?Also, although the symbols show peak An example of these essential packets are bridge protocol data unit (BPDUs) for spanning-tree topology configurations.
Fast switching is enabled by default. This root cause is one of the common reasons for high CPU utilization on the Catalyst 4500. You can use this statistic to determine how many additional TCAM resources are needed to hold the routes being advertised in the network at this time. When the switch hardware is punting packets, the row named sw forwarding is incrementing.
The change can lead to a traffic black hole if you have devices in your network which are mobile. To see which logging destinations and corresponding levels are enabled, read the header lines of the show logging exec command.
