Cisco Switching/Routing :: 4507 - CPU Going At 50 To 60 Percent
Nov 19, 2012
I am having a Cisco 4507 switch. The CPU on the switch is running between 50% to 60% constantly. To troubleshoot I collected some logs using debugs & show commands.
debug platform packet all receive buffer
show platform cpu packet buffered
debug platform packet all count
show platform cpu packet statistics
show processes cpu sorted | exc 0.00
show platform health
show platform cpu packet statistics
show platform health output shows the below process crossing the target value.

K2PortMan Review 3.00 5.35 15 11 100 500 4 4 3 1799:47
What I need to know is, though these process are running in Low Priority, will there be any issue if the CPU goes high due to these process.
We are running Cisco 6509-e and we are running load test and when traffic reach 80 mbps switch start reponding very slow. I checked CPU usage and it was using 100% and connection to the switch from outside to inside are 80K. once connection dropp Cisco release CUP and it start responding normal. [code]
I have two switches that always are with yours CPU in 39 or 40 %. the switches are:
IOS (tm) C3500XL Software (C3500XL-C3H2S-M), Version 12.0(5)WC3b, RELEASE SOFTWARE (fc1)
I think it's very strange the CPU always in 39 or 40 %. neither all ports of the switches are busy there are 6 ports free in each switch. 40 % I think it is a high value for CPU maybe because my IOS version 12.0 ?
I have one Catalyst 4503 with Supervisor 7L-E 10 with IOS - XE 03.02.00.XO. . One of its gigabit interfaces is connected to a Internet link of 1 Mega. In terms of QoS i would like to limit the total bandwidht of this gigabit interface to just one 1 Mega and simultaneous i want share bandwidth between traffic classes with bandwith percent up to 1 Mega and not 1Giga.
We have recently purchased a 5Mbit line with a second ISP and will have the line activated tomorrow. In addition, we recently obtained our AS number through ARIN. How would I configure the second ISP to be used for load balancing/failover?
SSH has been enabled on our one and only 4507 switch for several months and working fine. A few weeks ago the switch had to be reloaded and when it was back online I couldn't SSH to it. When I connected via the console and typed "show ip ssh" it came back saying I needed to generate the keys. Did that and it starting working again. The same switch had to turned off and on the other day due to a power down in the server room and when it came back the same thing happened again!!
The version of IOS is: cat4000-i5k91s-mz.122.20.EW
QoS design problem that I have. I have a client that is deploying new 4507 series switches with SUP6Es. The client will be running lots of voice, streaming video, and video conferencing over the LAN and want to base QoS on Cisco Media net recommendations.
I need to design a new QoS policy with focus on the above media services with basic queuing for critical data services. I have read the Media net design guide and the suggested 12-class model will be too complex to start with but I have seen references to start with a 8-class model with the ability to easily migrate to 12-class in the future. The 8-class model meets all of our requirements but I need to understand how this will work with the 4507 queuing model? [URL]
we have a core switch 4507RE at the data center and 2 departments that connect to it via 10Gig fiber using X2-LRM modules. Each department has a 3 switch stack and both locations are identical w.r.t type and setup scenario.the stack comprises of 1 x 3750E and 2 x 3750G . uplink is from X2 port tengig3/0/1 from the 3750E switch.
All of a sudden dept B started facing problem , where the ping would break and throughput comes around 6 - 7 mbps from that dept to the server behind the core switch. we also noted CRC error on both sides preodically.
we replaced the multimode fiber patch cords, re did the splicing , which stopped the CRC errors to appear.now since morning the uplink port on the 3750E (3/0/1) would suddenly be in "down" state with (err-disabled) as the status when i run sh int ten 3/0/1
and i can also see CRC errors and input errors on the same interface.. if i do shut / no shut .. the port is up and active again.. but this has happned 3 times today.the core swith side is still OK and no CRC / input / output errors are seen..
now on the 3750E i have swapped the 10gig module from 3/0/1 to 3/0/2 . the port is still up but i can see 400 CRC and 500 Input errrors.the module is also OK as i had replaced it with dept 1's module.
Is there a way I can find out the amount of bandwidth i'm using on a particular interface on a 4507 cisco multi-layer switch? It is a gig port and I have it setup for monitoring (spanning) and I see packets being dropped in the "Total Output Drops" area. To me it looks like it must be exceeding the 1gig limit but I don't know a way to check to make sure. I also have the queueing strategy set to FIFO.
i have a problem with a cisco cat. 4507 edge switch as when i have a login ssh session to the switch the supervisor engine restart and the redundant Sup. engine becomes the active and so on this problem mainly happen when i have multible SSH session to the switch and it happened very rarely with a single ssh login
the ios version i use is cat4500-entservicesk9-mz.122-54.SG which im using on all my edge switch and they are all working fine excpt this one
I have Catalyst 4507 R-E with one supersor engine n 3 other modules.My question is related to routing of different networks through this switch.I already have certain routes configured which are going to my ISP thru Juniper firewall.(192.168.0.9)I also have Cisco ASA 5510 which i want to use as a backup in case the first one goes down.
I have been trying to reset my Cisco 4507 R-E with sup 10GE engines, and I am not having any luck. I have followed the following document:
I have tried "wr erase" and "erase startup-config." I cannot delete the vlan.dat file either. I am using the command "erase cat4000_flash:vlan.dat" and its not working either. I have done these commands several times with no success. When asked if I want to save the config changes, I am answering with a "no" I have not tried to depress the small "reset" button on the front of the sup engines as I read that this just restarts the switch.
I have this cisco 4507 switch that I need to configure multiple ip ranges on. The problem is that I can only configure two ip ranges on it, one ip range on the management vlan and the other ip range on vlan 2. After I have configured these 2 vlans with different ip ranges, I can route between then and get them to talk to each other, but that is all I can do. If I add another vlan with a different IP range I cannot see it from the switch or get any of the otehr ip ranges to see it.
I am doing something dumb because this is a layer 4 device so it should be able to route the ip ranges. I have tried everything just cannot get it to work. I have assigned the IP range directly to the port number and directly to the vlans. Just wont work.
working first time on switch 4507 , this is my 2nd week and i plug the console on this 4507 switch , the switch reboots automatically it comes to stage mention below and reboots. My question is i have not seen any error message on this switch and it reboots automatically so what is the problem.

I am having an issue where MAC addresses from my user PC's are registering on different ports than the ones they are plugged in to. I have my PC's plugged in to my Cisco phones (most of which are 7941's), and then patched back to my switch, (4507 or 4006). The issue is that a user will be working fine, they will have both their PC and Phone MAC's registered on the correct prot and then with out intervention the PC MAC addresses will register itself with another physical port and the user will pull a 169.x.x.x address and have not access to the network. This is happening to multiple users all of which are hardwired. Port security is configured to allow 3 MAC's, obviously if I change that to 2 it will not allow an incorrect MAC's to register with that port, but I would like to know why this is happening. Both the 4507 and 4006 have been up for 1 year and 33 weeks. The fix has been to find out where their MAC has registered it self, unplugg that PC from the phone, and let the port security aging time (2min) clear all MAC's from the port.
We have ordered a new 4507 chasis with a supervisor engine.We have also ordered a spare supervisor engine.As per Cisco documentation WS-X45-SUP7L-E is shipped with a default IP base license.My question is that is this a e-delivery or a paper base license.The Cisco documentation also states that we can use the same license to upgrade both the redundant and active supervisor from lan base to IP base.
We are facing issue of high Latency and slowness with Switch Cisco 4507R at the Customer site.show logging for the Switch and if there is any IOS related issue [BUG] or some other finding for this case.
I have catalys 4507 with TWO supervisor V.I flowed this procedure : url...
after the reset normaly i can change the password and i check the confreg is 0X2142 but it still ask to enter the possword should i remove 1 supervisor and do the procedure or i must let the two spuervisor?
I have a requirement to monitor all traffic going from the internal LAN to the cloud. The LAN is a layer 2 VLAN which spans multiple Cisco 4507 switched and other smaller switches.
The VLAN has an IP address which the hosts use as the default gateway.
The exit port is on a Cisco 3600X switch connecrted to 4507 #1 via a 10G fiber link. 4507 #1 connects the rest of the LAN. Those switches interconnect via 10G fiber and 1G copper links.
Currently the monitor host is connected to a 1G copper port, configured as a monitor port, on one of the backside 4507s The switch manager says he has the switches configured so that I can see all traffic on the VLAN.
On a 4507 v12.2(20)EW, the connected subnets which are declared in the ospf instance are not propagated to the MPLS carrier router.Only the static routes which are redistributed in the ospf instance are propagated to the MPLS carrier router.
