Cisco Switching/Routing :: High Density Card For 6500E And 2T SUP
Jun 5, 2012
I have a customer that in the past has been using 6506E chassis with Sup32 and the WS-X6196-21AF cards for their closet.With the End of Sale of this combination and the announced End of Sale of the Sup720-3B announced, this kind of pushes the configuration to a Sup 2T.BUT the SUP 2T does not support these low speed high density cards.
Is there a card coming that will address need? Customer generally has had dual sup32's and 3 to 4 cards of the 96port AF.They stock spares besides haveing smartnet on the boxes or moving to a different platform like the 4510R+ or stacks of switches will mess them up.
I have read in some documents that we should have one Ap for more or less 50 clients. But i also read for example in ap 2600 specs that it support maximum 200 connections per radio.So for example in a conference room (10mx5meter) for 150 users in theory can i have just on Ap2600 for web surfing or i should have 3?
Is it possible to connect 3750X with C3KX-NM-10G to X2 10G port on sup2t in 6500E switch.There is Cisco OneX Converter Module, but I could not find that it is supported on sup2t.
I am writing with regard to a high memory utilization that we have on a pair of line card WS-X6748-GE-TX and WS-X6724-SFP for a VSS 6500. I am enclosing a little part of the "show tech"of this VSS 6500 where is possible to see the high memory utilization of the line cards 1/1, 1/2, 2/1, and 2/2, in despite of having some ports in state connected. In addition of this, the IOS installed on VSS 6500 is s72033-ipservicesk9_wan-vz.122-33.SXI6.bin for checking if there are some bugs affecting the behaviour of the Switch for this case.

We're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?
I have 3560's in my current environment, operating in the core/distro/access layers. The switches are in a star configuration, performs only layer 2 switching, and utilizes copper (no plans on moving to fiber).
With a fairly limited budget, I've been contemplating on upgrading the central node to a stacked 3750X to eliminate that single point of failure, and trunk the rest of the 3560's to the stacked switch. I wanted to be sure that the 3750X switches will be right for my environment (90-100 hosts), and if what I explained above is a good solution.
I'm also looking like to upgrade 6-7 of my servers (and SAN) with 10GB network cards. Do the ports on the 3750X have port densities capable of 10GB? If not, what switches provide that capability?
I am seeing a strange situation on my 6500 switch?By having snmp walk on '1.3.6.1.4.1.9.9.109.1.1.1.1.3' (== cpmCPUTotal5sec), I came to know that there are two processor and the cpu util for switching processor is gone to 88 % and some time creeps to 99 %.
snmpwalk -v2c -c "removes" sw6500 '1.3.6.1.4.1.9.9.109.1.1.1.1.3' SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.1 = Gauge32: 12 (--- this is for CPU of Router Processor ) SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.3 = Gauge32: 99 (--- this is for CPU of Switching Processor )
but when I do sh process cpu on the console, all looks normal as it shows cpu utilization of RP. why the value is so high on the switching processor ?
I am getting the following error message on a Cisco 2921 as a result of which has a there is 99 % CPU util. This router has the following cards installed and 4G WWAN EHWIC is running 15.1(4) M3 image.
I have 2 6509-E chassis with SUP-720-VSS and classic line cards :-(. on October 2011 the switch reached 100% CPU on both devices and the entire network went down. Customer restarted the core so we lost all the log files and couldnt find out any root cause on the same. TAC engineer suggested to have some script configured on the system in case of CPU shooting up above 70%, it will create a file in flash and keep appending the logs to the same. Last week i got call from customer saying that the CPU again went high for around a minute on both the cores. Last time i added CoPP also on the switch in order to prevent the CPU reaching 100%. Still it went high and from the captured logs i saw that the process created the high CPU was Port Manager Per and SSH process. Attached the file created by the netdr capture command.
The fans 1 & 2 in Module 1 on the Nexus5K are still experiencing the very high RPM and speed issue.
I have replaced the fan from another operational Nexus5K, and the fans are fine in the other Nexus. The replacement fans also have the same issues, so it is not a fan hardware issue.
There are no threshold alarms. the only log entry that is related to this is as follows:
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 1. 7950 to 12500 rpm expected. I have provided the output for both the fan detail and the temperature.

Currently, my Cisco 3750x (2 switches stacking) is having very hight CPU. Below are some of the output :

I am not sure what is using CPU to go up like this. I had tried some troubleshooting guide on Cisco web site like "Troubleshooting high CPU Utilization"
My 4500 core always in 60 % cpu utility , and when i run #sh proc cpu sorted i find that 55 29725041543795572214 0 39.43% 41.40% 41.39% 0 Cat4k Mgmt LoPri

my 3750-E Core Stack is connected to the Provider Router and is the DG for the internal LAN. I saw that the CPU is very high also in the night, but I found not the problem. I use an SVI to connect the provider due to HA reasons. I sniffered the network but saw no ecessive broadcaststorms. There was a PBR configured but I deleted it wihtout any success..
We are facing high CPU Utilization on Cisco 3750X-48P-L without any traffic on it. find the attached log files for 2 separate 3750's stack, we have upgraded the IOS of SW2 from "c3750e-universalk9-mz.122-55.SE3.bin" to "c3750e-universalk9-mz.122-55.SE4.bin" but still we found the same issue with CPU utilization.
I've been looking at reported problems with our Vdeio Conferencing kit attched to a stack of 3750's (which I think is down to QoS) but this got me looking at the logs. We get a lot of high CPU utilization warnings mainly for SNMP (315), Hulc running con (95), Virtual exec (289). I understand the last two are normal, and the SNMP one is probably Cisco Works polling as it happens every 4 hours.
However I've got an odd one: Apr 25 07:34:58: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 93%/0%, Top 3 processes(Pid/Util): 296/85%, 144/0%, 154/0%

Seeing very high CPU on one of our 3750X stacks. Usally its around 30% but recently its 70, 80, 90 or maxed at 100% during the main day.IOS version c3750e-universalk9-mz.122-55.SE1.bin.Has a ten gig uplink connected to a nexus 7k and another ten gig connected to another 7k. Running Layer 3 and EIGRP on the 3750X.Is this normal for the CPU?

From couple of weeks we have observed the cpu utilization of cisco 6509 with SUP 720 is high. During daytime from 9:00 to 21:00 it keeps increasing & reaches 98% & after 21:00 becomes normal.
I am facing a problem on a 2811 router. The CPU is remaining around 60% and the router throughput is reaching at most 18 MB while according to the data sheet the 2811 maximum throughput is 61MB. I have checked the output interpreter in order to try and figure out the cause of the high CPU and to determine if it is affecting throughput but there are not processes consuming more than 10%. I have attached the show tech-support and the show process cpu history outputs.
in both case some times i obtain lowing traffic on interface and highest cpu - to 100% after clear cef linicard i obtain growing traffic and cpu 0%

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.
I have some events where the CPU utilization in a cluster switches of WS-3750 is going to 100%, the process with the major utilization of CPU is the "hulc running con".
I found cpu load around 90 - 100% on cisco 3845, so I show tech-spec and show log on router and found process "Virtual Exec" use high load. I'm not sure this situation make high latency time on my network.
We have seen high CPU utilization on some Cisco switches of type 2960S. Also we got info, that applications are running with poor performance or with interruption.Following IOS is loaded: C2960s-universalk9-mz.122.55.SE
