No 100 Mbps with cisco 892 router, cpu caps

Hello

We have a connection internet-based corporate (100 Mbit/s down, 10 Mbps upward, certain guarantees) with eight fixed ip addresses (in the a.79 configuration.72.  To join our network to the internet, we use a router 892.

I am new to cisco equipment, so I had some trouble getting things to work, but I arrived.

Now, we are facing this problem of throttling: whenever we are using more about 60mbit/s down bandwidth, this router CPU is maxing out (98-99% with 'show processes cpu history').

When I download a torrent (dvd debian) to 4 MB/s (or 48mbit/s) cpu running at about 46 percent (tops at 49%).  Stop the download of results in 14% at the top of the CPU usage.

When you use the command 'See deals cpu sort', I get this:

Maximilian #show process cpu sort

CPU utilization for five seconds: 46% / 43%; 01:00 %; 05:00 %

If the CPU usage is about 46%, so that no process uses actually more than 2.31%.  In addition, these numbers do not change if I stop the download.

Please tell me what I can do about it.  Or this router is not able to do 100 Mbps?

The net effect of running out of CPU is random connections abandonment and no possible communication with the router.  I could cap the bandwidth 90mbit/s or 80mbit/s, but I'd rather not.

The system of image files is: "flash: c890-universalk9 - mz.152 - 1.T1.bin.

Poster

In fact, the 890 series is rated at 100 Kpps, i.e. approximately 51 Mbit/s (noted also in other posts) for minimum size Ethernet packets, but Cisco also documents the 890 providing up to 1 400 Mbit / s 1500 bytes of the packets of size.  Unfortunately "your mileage may vary." i.e. actual throughput is very dependent on your particular traffic and you configure your router to do against this traffic.  For example, you have NAT/PAT, ACLs, firewall inspection and NetFlow, all who consume extra CPU during the processing of packages of the interface.

Not knowing what exactly will a customer with a router, Cisco makes recommendations to use very conservative, and for the 890, it recommends side WAN does not exceed 15 Mbps (duplex).  Again, it is very conservative, and as you have discovered, your configuration hit the wall about two times this recommendation, although it is unfortunately not enough to manage your bandwidth capacity.

As other posters have noted, long-term or preferred solution is probably getting and using a faster router.  You can probably get out a title plus your 892 with additional 'tuning '.  That is, by eliminating all what you really, really need and do what you need as efficiently as possible.  For example, disabling NetFlow (such as already mentioned in some of the messages), disabling the firewall dynamic as you have NAT/PAT and ACL; and the "Resequencing" (if it is logically possible) ACEs.

Regarding your question of the use of the services of police or release in the form, to avoid any overrun of the CPU (which really want to avoid!), Yes, something can be done there and could be very beneficial, but you will use some CPU for that and a really intelligent approach would be complicated.  (An example of 'smart' approach would be a built-in script that queries CPU frequently or traps these slow flows on high CPU, which then finds the high flows and policies dynamically.  A not-so-smart approach would be one policeman static for all incoming traffic, or only certain types of traffic entering the police.)

  • C6180 print wireless with Cisco E1000 router problems

    Hello

    I recently got a new Cisco E1000 wireless router and am not able to print to my HP C6180 printer wireless.  I ran the diagnostics wireless to the printer and all past.  The printer has an IP address, etc.  However, neither my wife nor I can print without wire (connected to the printer works) on its Apple or my PC.  She gets "the printer is offline.  I found an old post which has me download and install the diagnostic utility network HP but that the utility could not find all the printers and after tinkering with it I could get still not work.  I think the printer wireless radio is dead (but then how do I connect to the router and have an IP address, and go to the configuration utility) or the N wireless router is not compatible?  Or hopefully something we can fix.  Thank you very much in advance for your help.

    Ross

    If the printer has an IP address, then it must be connected to the router OK.  You've restarted the router?

    We could define an IP address of the printer:

    -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
    -Enter the IP address in a browser to reveal the internal settings of the printer.
    -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
    -On this screen, you want to set a manual IP address. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). Yours is 192.168.1.100 a.149.  Allows to select 192.168.1.200 for your printer.
    -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
    -Enter the IP of your router (on the Page of the Network Config) for the bridge and the first DNS. Let the second white.
    -Click 'apply '.

    Now, stop the router and printer, start the router, wait, and then start printing.

    After that, you will have to redo 'Add printer' using the new IP address.

  • JWNR2010v5 (N300 wireless router) will support 100 Mbps connection speed internet in LAN?

    I intend to upgrate my internet connection speed of 60Mbps to 100 Mbps, but my provider says JWNR2010v5 (N300 wireless router) will not support 100 Mbps internet connection speed in LAN. Is this true? that which is the maximum speed of JWNR2010v5 for the LAN support. I don't mind the wireless speed, I use the maximum LAN. Thank you in advance.

    Your provider is correct. Either move your router to a router which supports! 000Mbps (MGI) LAN and WAN ports or stay at your current speed Interent.

  • Attempt to connect wi fi on my Dell computer, running windows XP? Have DSL but not Ethernet. Faced with problems. Checked with CISCO router but not help there. CANY anyone help

    I have a problem connecting to a Cisco E100 router to my computer. My count (office) does not have a wireless. I have DSL from. Cisco tells me to plug a router using Ethernet cable to connect. I don't have an Ethernet connection on my computer. At present I have USB connect the computer to the Westell modem.  Can anyone help? I hope this is enough information. Basically what I'm hoping to do is to install the WiFi so I can use a tablet now and maybe a laptop this last on.

    Thank you

    On the routers only house you can use USB connections are those provided by some ISPs.  An Ethernet connection between the router and the computer is far more preferred.

    Your router a Cisco E1000 or is it really E100 (I thought that Cisco makes a model with this designation not)?

    It is quite surprising that you don't have an Ethernet connection that is built into your computer.  What is the complete model number (or, preferably, the Number of Service Dell)?

    Open the Device Manager (start > run > devmgmt.msc > OK).  Expand the "Network card" category by clicking on the + next to him.  What devices are listed in this category.

    If you don't really have an Ethernet or an adapter wireless built into your computer, you can add one, using a PCI internal (if you have a desktop/Tower computer) or external (PC card for laptops) or USB to laptops or desktop/towers.

    Also, the normal configuration is to connect your DSL modem to the router and then the router to the computer.  If your Westell modem has an Ethernet connection, you must use your new router in a non-standard configuration.  Even if the Westell modem has an Ethernet port, you may need to do some reconfiguration for her as well.  What is the complete model of the Westell modem number?

    I'm trying to figure out what makes the default entry of the 192.168.54.202 router in your DHCP pool? It usually comes to 192.168.11.1 or whatever you want your router to be. You need to add the following commands:

    interface F8

    IP nat inside

    interface G0

    NAT outside IP

    IP access-list standard NAT
    permit 192.168.11.0 0.0.0.255

    IP nat inside source list NAT interface G0 overload

    That should do it. If you have any other questions, I would recommend turning off your modem cable for a few minutes and then turn power on and then turn your router. To see if you have received an IP address, you can run a show ip interface brief and next to G0, you should see an external IP address.

  • HP Envy 15 TS (C8P47AV): can't get Realtek GBE onboard Ethernet RTL8168 go above 100 Mbps

    I've only used my HP Envy TS 15 (C8P47AV) wireless and recently got a wired connection using CAT7 at my desk on the 2nd floor. I can't exceed 100 Mbps and it is extremely frustrating! I've read tons of things on the web and can not find something that helps! My WiFi gets a faster than the Ethernet cable speedtest. I see this change once! That's when I changed the cable that I have my router on and noticed he went to 300mbps and things flying. However him unplugging and plugging it into which he disappeared port. It's almost like the old bargaining hung. In any case change this to force it to work? I tried gigabit forced, you name it, any setting changes you fixed! I even tried to plug directly into the router port and that it did not. I have other devices that work fine with this same CAT7. I'm SOL with this version of HP laptop?

    I found the problem! After reading each thread only forum I could find on Google. Someone suggested to see if there was a brooch twisted in the connector and of course the middle one was bent! I don't know how it happened as I've only used wifi. It's a little tricky but I folded it back turned and I was ready to go! The chalk of it as not a cable problem or driver!

  • Compatibility of VLAN with Cisco

    Hello

    We just bought 10 x new Netgear switches (all M4100) to add to an existing Cisco infrastructure.

    Simple configuration with only 6 Valns.

    5: Admin, 30: VOIP, 101: management, 100: a set of Workstations, 102: second series of Workstations, 200: IPTV, 400: Internet, 401: Wireless Management

    All I wanted to do was: 2 last ports each switch netgear = T and all the VLANS. I have not identified all ports if I want to use in the appropriate vlan

    101 of VLAN is my Managementt Vlan. (Need to configure inter vlan routing for this to work)

    I only turned on three switches up to now and all three do not work. They work for a while and that packets but do not receive all.

    What I am doing wrong?

    What I need to get rid of the original vlan1 on the netgear?

    Is that what I need config in the STP to make these compatible with Cisco (300 and 400 series) switches.

    I use an optical backbone on Cisco and Netgear switches.

    Sincere greetings,

    Hi Moussa,.

    Thanks for reaching out.

    We got it working.

    Step 1: upgrade to the latest firmware.

    Step 2: Forget the MISTLETOE.

    We had a few questions about the old firmware - causing links to trunk have some incompatibility with their tag and removed the images between Cisco and Netgear brand.

    After the upgrade of the firmware that we had access to "switchport mode access" and "switchport mode trunk" orders fixing the access port and trunking issues.

    Thank you Mr President,

  • WNR2000 v2 does NOT offer to 100 Mbps port speed

    I got a plan of 100 / 10 MB/s and I noticed that with the WNR2000 v2 on a wired connection (cat 5e and cat 6), it is always capped at 75 / 10 Mbps.

    However, when I use gigabit router/modem my ISP, I get 130 / 10 Mbps.

    Why not reach the port on my router netgear speed, it's rated specs?

    I guess that you only use the ethernet connection.

    WNR2000v2 LAN port can handle 10 / 100 Mbit/s, but in reality you can't reach the exact speed or more than 100 Mbps.

    You were able to achieve more than 100 with the modem because the modem port is gigabit.

    It's a decent speed for this old model.

    You have the latest firmware installed?

    Try to do a reset and then see if it will improve.

    Just on the side note, you can see this table.

  • WRT1900AC seems to limit myself to 10 Mbps when the gateway computer gets directly 100 Mbps

    My gateway xfinity is a TC8305C. I "bridged mode".

    If I have my computer directly in the front door, I speedtests of ~ 120mbps, no problem.

    However if I insert my Linksys WRT1900AC in the Middle, I get only for speeds of the order of 10-12 Mbps, MAX I tried three different Cat5e cables (including the one provided with the modem router and one supplied with the router) between the router & gateway, with no improvement in the result. The cable from the computer to the router is the same one that works > 100 Mbit/s if I connect directly to the front door.

    I need to use the router to run my network for a variety of reasons, but I don't want to give up 90% of my bandwidth!

    Did I miss something? Someone suggested, I set the ports manually to 100 Mbps instead of having their auto-negotiation, but I can't find any option for this in the firmware. My firmware version is 1.1.8.164461 which seems to be the latest version.

    Thanks in advance for any help!

    Activate Media prioritization and set the bandwidth downstream to 120mbps exactly. Quit all devices and the app to normal priority.

  • WRT160N, auto-negotiation has failed at 100 Mbps, can wall jack be the cause?

    Hello

    Can someone please help me with may be a simple problem for you, but it starts to drive me crazy. Sorry in advance for the long post.

    WRT160N installed in the basement, linking (cable) 3 desktops and 2 laptops (wireless). When connecting by wire, some computers have troubles in autonegotiation speed, always end upward with connection failed. Force the speed of 10 Mbit/s full duplex solves the problem.

    Curiously, both computers have no problem to 100 Mbps Full Duplex auto-negotiation (HP nc8430 laptop with 5 years and the Broadcom NetXTreme Gigbyte old IBM ThinkCentre M50 8189-Tower network chip, I do not know the exact network chip, but I think that until the Gigabit). Less than 1 year of office by using a Committee of Asus P5N7A-VM with the integrated Realtek, also Gigabit network chip, still FAILED to negotiate at 100 Mbps. The wall plate has 4 Sockets. The question above is the same regardless of any plug used.

    After several attempts, I think I've isolated the cause to the wall outlet. There are about 6 metres of cable (~ 20 ft) between the router and the wall outlet. The computers connect to the wall using a cable of 2 meters (~ 7 ft). Go through the wall outlets, I pulled a 10 meter cable (~ 30 ft) connecting the router directly to the computer, then the computer is not always to 100 Mbps now could connect without any problems. So, this seems to indicate that the wall socket has altered the quality of the signal.

    The cables (between the router and the wall) are straight with T568B wiring (http://en.wikipedia.org/wiki/T568A/B#Wiring) the sockets are CAT5 RJ45 Keystone Jack free tool (http://www.amazon.com/CAT5-RJ45-Keystone-Jack-Black/dp/B000BSN7RO)

    So here are my questions:

    Q1. A wall outlet would cause a loss of significant signal or alteration?

    Q2. If the wall outlet is the cause of the loss of signal quality, how is it some computers have no trouble to autonegotiation to 100 Mbps Full Duplex and also when forced to 10 Mbps FD, all network problems disappear?

    Q3. And the most important question: can you please provide a solution?

    Thank you very much in advance for any help.

    Hello

    Follow up and FINAL solution to close this thread. The cause was the wall outlet. All sockets are of the type version tool-less Keystone Cat5e. All the exihit speed negotiation issue and can be used at 10 Mbit/s full duplex.

    I could borrow a punchdown tool and tried a new plug. This time, I tried Keystone Cat6 jack _WITH_ tool. Can be overkilled my cable is Cat5 only. But I don't want to take any risks because the price difference is negligible between Cat5e and Cat6 decision. The new Jack is working perfectly. The AutoDetect computer easily at 100 Mbit/s/s. The fix is so obvious, as soon as I replace threaded plug by a Jack of tool WITH the speed issue disappeared. I have connect / disconnect several times, even restarted the computer to ensure that the new Jack is working OK

    Although I'm not a guru in network cabling. But I'm not computer (using Windows & Linux) and I'm quite a handyman. I can't possibly screw up Assembly of ALL taken without tool, I've had. And the misconfiguration of the network in the operationg system is out of the question. Added to this fact that the new tool WITH jack is much easier to mount and all prectly work on the first attempt. I would say in conclusion that WITHOUT TOOL, CLAMP in Ethernet JACKS are UNSTABLE. At least that's my experience.

    It's pretty frustrating, that Jack is the last place I guess as a cause of a wiring problem. I changed to RJ-45 Sockets, wiring maps network and same router. All this has not solved until one day I discovered by chance that the cause was the wall outlet. (New computer loan with Ubuntu, I forgot to reduce the network speed to 10 Mb and directly connected to the switch without going through the wall socket and discovered that the computer can connect immediately to 100 MB).

    Hope this might help someone else.

  • Wired WRT610N 1Gbits fall to 100 Mbps, after awhile

    I start my XP SP2 computer and router wired port 1 (the only wired) show connected green (this average 1Gbits until they fix it) and everything seems fine. After an hour or two I have a message if poster near the time on the network disconnect and then reconnect then disconnect, etc. for abour 7 - 8 times now then it reconnect to 100Mbits (LED is now blue). It is the second time that it is happening now. My computer runs usually 24 hours a day, but I rebooted twice this week. I don't like the loss of speed because I have higher than 100 Mbps but there is a problem here and I think LinkSys should take a look. Network card is an Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller

    Well, after a HD crash I installed a fresh copy of the operating system and then entered WindowsUpdate and found that there is a newer driver for the network card.  I guess it was there before, but never really looked and now the new installation of the OS has forced me to look at all available updates.

    Since then, the light stays green on the router.  I know blue should be 1Gbits and is a flaw in the current firmware and why LinkSys is not faster to give us that a new firmware for their instruction booklet info will correspond to the reality, is a mystery.  As the firmware that they are testing for months now to solve some disconnect problems.  Never thought Cisco might be THAT slow.

    In any case, I wanted to present my conclusions and label this thread resolved so if someone has encountered the same problem they could possibly fnid a solution.

    Thanks for your post. I had a look at your configuration, and it is great that you are a few short steps on your NAT is why it does not work. Please follow the steps below in order to get this work properly.
    1. first of all, let us remove the old configuration NAT then back to a clean slate with the following commands.
    no ip nat inside source list nat-list interface GigabitEthernet1 overloadclear ip nat translation *
    2. now, we will create a list of access control allows for NAT traffic and create the new NAT statement for that tie together. * NOTE: If the version of IOS, you are running requires mask rather than generic then change 0.0.0.255 to 255.255.255.0.
    
    
    access-list 100 permit ip 192.168.1.0 0.0.0.255 anyip nat inside source list 100 interface GigabitEthernet1 overload
    3. the next step is to specify the logical role of the interfaces in question, whether they are 'inside' or ' outside'.
    
    
    interface vlan1 ip nat inside exitinterface GigabitEthernet1 ip nat outside exit
    4. Finally, save us the configuration and reload.
    
    
    copy run startreload
    After the unit is returned as a result of charging, please try again. In some cases - depending on the version of the IOS, you have to ping the outside world from a computer on the local network rather than just sourcing of the interface VLAN. Try this back and forth, and let me know how get you there. I can't wait to hear back.
    
    
    
    Kind regards

  • ISA500 site by site ipsec VPN with Cisco IGR

    Hello

    I tried a VPN site by site work with Openswan and Cisco 2821 router configuration an Ipsec tunnel to site by site with Cisco 2821 and ISA550.

    But without success.

    my config for openswan, just FYI, maybe not importand for this problem

    dpddelay = 30

    I tried ISA550 a config with the same constelations, but without suggesting.

    Anyone has the same problem?

    And had anyone has a tip for me, or has someone expirense with a site-by-site with ISA550 and Cisco 2821 ipsec tunnel?

    I can successfully establish a tunnel between openswan linux server and the isa550.

    Patrick,

    as you can see on newspapers, the software behind ISA is also OpenSWAN

    I have a facility with a 892 SRI running which should be the same as your 29erxx.

    Use your IOS Config dynmap, penny, you are on the average nomad. If you don't have any RW customer you shoul go on IOS "No.-xauth" after the isakmp encryption key.

    Here is my setup, with roardwarrior AND 2, site 2 site.
