I have a router 3845 with c3845-advsecurityk9-mz.124-24.T6.bin software . Frequently we are facing problem in logging to the device .Inorder to resolve we need to reboot the router . Yesterday fortunately i have got the console access for some time so i came to know that TPLUS process is consuming 99.9% percentage cpu.

We are experiencing with high CPU input due to ARP input between 20:30 and 22:30 every day At this time we have a lot of backup operations. When I look the netflow report, I can't see anything anormal.
We are changing our backup server's NIC card from 1gig to 10Gig. The backup operation's traffic is high (approx 2Gbps level) but 6509 has to be handle this size of traffic.
We are using two 6509E in VSS mode and our image version is s72033-adventerprisek9_wan-mz.122-33.SXJ.bin

We are running a stack of 2 WS-C3750X-24S-E's with IOS version 12.2(58)SE2 and we are seeing continuous high processor utilization involving the hl3mm process. The stack is configured for PIM Sparse mode, with 2 upstream Nexus 5596'es acting as both RP candidates and as BSRs. The hl3mm process generally runs at about 19% but can spike up into the 60% range.Symptoms on the 3750X are spiking latency and sluggish CLI perfformance. I thought at first that we might be running into SDM limits, but the "show platform tcam utilization" show that we are far under the limits of the default SDM template. Performing the "show ip pim (vrf name) bsr-router" command freezes the system and takes 20-30 seconds to return results. Similiarly configured WS-C3750G-12S running 12.2(55)SE3 does not exhibit these same issues.

I have in my router 2801, one link with 20 MB WAN Connection, and it is presenting high cpu utilization with 97% Interrupt Errors when start one download.
I exchanged it to another router the 2811 and it presented the same results. I read the cisco document about Router Performance.
And it speaks about the 2801 supports 46 Mbps using CEF/Fast Switching and 1.5Mbps using only Process Switching, and 2811 supports 61.44 CEF and 1.5Mbps Process Switching.
I need to know if the NAT Process is process switching or CEF Switching. Because if it was process switching the router is working in the max capacity and i will need to exchange the hardware to a better hardware.

I have two core switches - 4506E, and i noticed there are frequent cpu spikes on both of the cores switches. As its spikes intermitendly i couldnt able to anlyze the issue. I need inputs on the following,
1) Is there any Free CPU process monitoring tools to identify which process is spiking ?
2) Troubleshooting techniques to identify the issue.

I have two C4506 switches and I would like to create two L3 links between them by using only one physical link. I will then assign each L3 link to a different VRF.
I think I have two choices but I'm not sure however that the second one is possible...
---------------
1st choice: creating two VLANs and two SVIs on each switch
interface Vlan10
ip address 10.10.10.1 255.255.255.252
ip vrf forwarding vrf1
interface Vlan20
ip address 10.10.10.5 255.255.255..252

We have a Cisco 886 configured with two WAN's (ATM0 connected to a DSL line and Fa3 connected to a CMTS modem).We're running DMVPN over the Cable network and GetVPN over the DSL line. When the DSL line is down we see a lot of CPU peaks up to 90%.The CPU peaks are caused by the process "DSL state machine". As soon as the DSL line has sync and the ATM0 interface goes UP the CPU peaks disappear. What we'd like to know is if this constant extra CPU load will have an impact on other resources like normal routing & switching or more specific IPSEC handling. Is it for example possible that establishing an IPSEC tunnel will fail because of the CPU peaks?

I have an issue with 7600 router where CPU goes up to 60-70% and memory is also high. Both due to BGP Router process. URL We are seeing this issue since ISP has upgraded their router 20 days ago. Router also seen following error.I have not reset the BGP session with ISP yet. Is there any way I can supress BGP updates coming from ISP and see if CPU and memory USAGE reduces.

Router has 1 eBGP session with ISP from where it downloads whole IPv4 internet routing table and two IBGP session with other two rotuer. When I look at BGP summary table I see many updates received from ISP and sent out to IBGP neighbors. Also did debug BGP updates to confirm it.
We are seeing this issue since ISP has upgraded their router 20 days ago. Router also seen following error.

I have a Catalyst Switch 6000. Inoticed that after the execution of the job inventory in LMS, and after the snmp queries reached the equipement, the cpu value reached 98-99 % due to the process : PDU DISPATCHER (what’s it ?)
I have also a script running in the switch to observe the differents logs. For exemple, when high cpu is obtained, the message bellow appear :

We are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco. We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages. Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication. In the past, because they are logged into the domain internally, the website authenticates and loads. After switching to the Cisco, it asks for a password even though they are logged in.
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.

I've been reading the documentation for the new 3750v2 switch, and I'm wondering is the IPBase license supports FULL OSPF. The product sheet notes that it supports OSPF in the IPBase license, but then further down the page it notes that for advanced routing functions (EIGRP,OSPF) you need the IPServices license. Are there any limitations to the OSPF process on a 3750v2 with the IPBase license?
