Cisco Switching/Routing :: C6K Randomly High CPU Usage C6509
Mar 20, 2012
We have two c6509 budled in VSS. I have noticed randomly high usage of CPU, sometimes up to 99% in peaks. I have found that it can be generated by SNMP engine. So I unconfigure all SNMP things. But situation is the same. I would like to know if this state is OK or not. CPU shows are enclosed in file.
I have a 2 cisco core (cisco WS-C6509-E (R7000) processor) and been working for quite sometime.they are conneted with HSRP with active standby config with a 10 g module for redundancy just today I see that the cpu utilization went to about 50% and its the same on both cores.
We are facing issue of getting very high CPU utilization for the VSS Switch model WS-C6509-E some times approx 100%.Attaching here show tech-support taken later after CPU normal along with show logging, show cpu sorted.HCAINNOI01XXXCS0001#sh proces cpu | ex 0.0%CPU utilization for five seconds: 100%/13%; one minute: 90%; five minutes: 91%PID 5Sec 1Min 5Min Process16406 91.2% 75.2% 76.2% ios-base16426 1.7% 1.4% 1.4% udp.proc16429 0.3% 0.3% 0.3% raw_ip.proc16432 2.8% 3.1% 3.1% cdp2.iosproc

I'm having issue with one stubborn process that is consuming nearly all the CPU on all of my switches. I tried googling it, but had no luck. The process is "hulc nrgyz PD di"
We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high. This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure. Below I provided some outputs about how to diagnose it.
I have a 2 Cisco 3750X stacked working as CORE switches but not in production yet showing a high CPU utilization and I would like to see with you whether you think this is normal or a IOS upgrade/downgrade should be performed.
I have very low traffic coming through as this is not yet in production:
I have having two Cisco 6509 both working are my main Core Switches with which I have all my Layer 2 VLANs configured and then distributed thru the trunks links to all the Access Switches. I have L3- Vlans also configured on them with which one switch in primary and the other is secondary. All of sudden last night I got this message on my core switch 2 this for VLAN 1 which is my users LAN, how can I check as to what would have caused the core switch 2 HSRP to be active and then in standby
*Nov 5 23:33:29.296: %HSRP-5-STATECHANGE: Vlan1 Grp 5 state Standby -> Active *Nov 5 23:33:29.796: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Standby -> Active *Nov 5 23:33:29.804: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Active -> Speak *Nov 5 23:33:29.920: %HSRP-5-STATECHANGE: Vlan1 Grp 5 state Active -> Speak *Nov 5 23:33:40.144: %HSRP-5-STATECHANGE: Vlan1 Grp 5 state Speak -> Standby *Nov 5 23:33:41.280: %HSRP-5-STATECHANGE: Vlan1 Grp 49 state Speak -> Standby
Also last night i got call from office saying that we are getting huge delay in pinging the default gateway of the user LAN which is the same vlan as the above and it was just for few minutes and then it was back to normal and now when I came to office and check there were no logs in both the core switches. When I checked the cpu utlization it was showing me high on both the switches how can I check as to what would have caused the CPU utilisation to go high all of suddedn?

We would like to install a WS-SVC-WISM2-1-K9 in each of our 2 WS-C6509-E chassis. Both of these have supervisor 720 engines installed. One in each chassis.From what I have read we need to upgrade the IOS to 12.2.33 SXJ4. Is this correct?If this is true then what are the memory requirements for the upgrade to this IOS version. Below is the output from Show version?Is there sufficient memory instqalled to do this install?
we plan to implement VSS on our datacenters (C6509/Sup720), in order to remove L2 loops (currently, access layer are C3750 stacks, which could evoluate for N5K/N2K). I would like to have some feedbacks about VSS stability. Some years ago, I have seen some bugs with this technology in another company, so I am still not totally comfortable to use it in the datacenter.
We plan to implement a large number of ACL on our Distribution switch which is a HSRP pair of 6509C switches running on sup-bootflash:s72033-psv-mz.122-18.SXD3.bin WE need to divide the Network in three layers
unsecure layer Proxy layer Secure layer
We have approximately 250 vlans on the our distribution switches and plan to implement 15 ACL on different vlans Each ACL can contain upto 30 lines or less.
basic ACL example we will be applying on different vlan vlan 200 ip access-group test123 in
My question is Can these ACL on a vlan can have a massive impact on the 6509 CPU ?
Last night, the C6509-E do a unexpected reload. In the crashinfo, I can see that the last error message before the reload, was as follows: %C6K_ PLATFORM-SP-2-PEER_RESET: SP is being reset by the RP
I consulted the cisco website about this error message and what I found was the following:C6K_PLATFORM-2.
what should it be the minimum IOS version that I require on my WS-C6509-E equipments to support "logging origin-id" command?
Cisco documentation says that this command was introduced in 12.2(15)T, and integrated into 12.2(33)SXH. BUT my Cisco switches have 12.2(33)SXH5 IOS version......and they do not support "logging origin-id".
(config)#logging ? Hostname or A.B.C.D IP address of the logging host buffered Set buffered logging parameters buginf Enable buginf logging for debugging cns-events Set CNS Event logging level console Set console logging parameters count Count every log message and timestamp last occurance esm Set ESM filter restrictions event Global interface events exception Limit(code)
I operate between c6509-E, what did you flooding? its just packet capture gi1/3 but i dont know it and is it attack?also same seq no switch gots it?what is problem?
we have a WS-C6509-E WITH SUP VS-S720-10G, and IOS s72033-advipservicesk9_wan-mz.122-33.SXI5.bin. [code]
From, what we can see, whenever we try to clear arp-cache, it doesn't remove the IPs from the ARP. We've checked a bug in the IOS 12.2(33)SXH4 with the same issue, in version SXI4 is solved, but I have version SXI5, it is supposed to be fixed, from this caveat CSCtf16300, since it says it was fixed on 12.2(33)SXI4, it should be fixed on SXI5, right ?
Both regular IP traffic and ICMP traffic are passing through the source port. C6509 provides the option of filtering vlan traffic during monitoring. But I don't have vlan traffic.
I have a C6509 with WS-X6548-GE-TX port module. The first port group, 1-8, is showing oversubscription (packets dropping) in the shared buffer. What interface commands can I use to find the specific port causing the buffer overflow?None of the ports is continuously overutilized and none of them in a SPAN destination group.I don't want to move connections without knowing which one is causing the problem. Also I fear that moving the connections may shift the bleeding to another shared port group.
I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration
I have Cisco WS-C6509 with IOS version 12.2(18)I have several vlan interface on this device.Today I create new vlan intervace
interface Vlan165 description test5 ip address 10.10.10.1 255.255.255.252 end
and vlan:
VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 165 test5 active Gi7/14
But I can't ping this IP address and show ip route shows:
sh ip route 10.10.10.1 Routing entry for 10.10.10.0/24 Known via "static", distance 254, metric 0 (connected)
I have static route for this subnet /24?I can not see any error in logs, but looks like I reached vlan interface limit on this device or something like this.How can I check it?
I am trying to figure out what is heat dissipation of a C6509-E configured as follows:
1 x WS-C6509-E-FAN 1 x VS-S720-10G-3C 1 x VS-F6K-PFC3C 8 x WS-X6748-GE-TX 8 x WS-F6700-DFC3C 2 x WS-CAC-6000W
I have tried two ways: 1) the power calculator and 2) manual calculation using the C6500 installation guide.
1) The power calculator says 13630 BTU/h 2) Manual calculation says: [code]
The there should be also the two PS in the picture, and the new total should be: [code] Well, 62711 BTU/h looks quite a bit too much and I think that the heat dissipation of the power supply should't be considered in the calculation.Isn't it an item that takes power from the grid and that generates heat according to its efficiency as the other modules?
Network newbie need to verify all necessary services and protocols on a new WS-C6509-E are turned on. This layer 3 switch will be used to connect to servers.
we have cisco WS-C6509-V-E with IOS version 12.2(33)SXI4; s3223_rp_IPSERVICESK9_WAN_M) running on a switch. I am trying to configure the command "mac-address-table synchronize" under global config mode. But when I enter the command Cisco(config)#mac-address-table ?It doesn't show the synchronize option?
I am trying to find a command for dhcp snooping rate-limiting on a CatOS. The PFC card is PFC. PFC3B is said to support that command. But there seems no this command.

We are planning to replace a few line cards in the existing 6509-E chassis. The sup installed is a VS-S720-10G-3C but the line cards are legacy. As a result we are not able to enable the VSS functionality. We are looking to replace the existing line cards with the following:
1. 1 x WS-X6716-10G-3C 2. 1 x WS-X6724-SFP 3. 4 x WS-X6724-GE-TX
What are the requirements in terms of IOS and Roman.
The current IOS is: Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICESK9_WAN-M), Version 12.2(33)SXI2a, RELEASE SOFTWARE (fc2) And the ROM Version is: ROM: System Bootstrap, Version 12.2(17r)SX7, RELEASE SOFTWARE (fc1)
I've a big problem with a loss of packets ICMP sent by different hosts in differents VLAN. Here my architecture:
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective.Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires.Topology: redundant ring
When I send consecutive ping message I found always a missing of packets . Furthermore When I insert the "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.
I have recently configured secondary ip address on LAN Interface of Cisco C6509.. We have some application which needs to use broadcast traffic communication to communicate with client... Broadcast is working within subnet & also working from broadcast server to primary subnet. But not working from secondary subnet.. I have checked broadcast within secondary IP range & it's working fine... Secondary not working broadcast with primary and also with broadcast server... broadcast address is different for these subnet but both should be communicate since configured on same interface... When I went through Cisco website found that command "ip directed broadcast" which will pass broadcast to different subnet... But I'm not sure whether any other impact if I enable that command on particular Ethernet interface...
When a physical switchport/routed port has high usage, you can move the link to a higher capacity port, upgrade the port, bond links, etc. What exactly do you do when an SVI has high usage? I guess you could remove some servers from the VLAN, but that doesn't seem like a reasonable solution. What dictates the capacity of an SVI? The backplane of the switch?
I have a 1841 router plugged into a 100M Comcast ethernet connection. My router cpu is really high and users download speed isn't as high as before. Can a 1841 handle 100M circuit with 100 users on it? What would cause the router's cpu to be high? I don't think there are any viruses or malware on the lan.

I have a lot of cisco 7206 vxr deviceses. I have a high cpu problem.I have a 7206 vxr g2. I used to use ebgp for three upstream carrier. I used to bgp full route table method. I have about 800 Mbps active traffics and behing the router about 1600 active customers.
How can I trouble shoot this high cpu problem?

I have a Cisco 1921 router and it uses 99% of CPU and i cant seem to spot wich process that is taking up the cpu. I have an interface with several sub-interfaces and i am moving data between two of those subnets, i tried the "ip route-cache same-interface"-command on giga bit ethernet 0/1 with all the sub-interfaces like gigabitethernet 0/1.18 and so on. That did not work.
