I am trying to understand if Cisco 4948E can do the same job as Cisco 4500E or not and difference between Netflow v/s Netflow-Lite will work for me to select correct product.
how I configure netflow on a cisco 877 router.
I have an interface e0/4 that is 172.1.1.1 on router one (network one) which links to another router (onnetwork two) which has an interface of e0/4 172.1.1.2 which allows two networks to communicate. Network one is 192.168.0.0 /24 and network two is 10.255.255.0 /24.
How do i configure netflow to monitor the traffic going through these interfaces?
Does the 2911 router support the ability for Netflow V5 to pass through GRE tunnels? I can't seem to find any documentation that indicates this.

I have customer that we have configured netflow on the 2821 router that their traffic is on. Currently the company they have contracted with for the analysis is seeing data duplication. Below is the configuration for the interface and the router

The inet was working through the router (we get it off our neighbours), now our neighbour is our grandad and he doesnt use the internet (his daughters do but they left home). So we decided to take the router around to our house because the signal would always be very weak in our house (but it worked.) So we connected an ethernet cable, that goes through the roof of both houses attics and into my room, and plugged the router in there. back in the other house, the wire is going into the modem.
So we have the modem in one house, with a big wire going to my house into the router. We turn it on and it works, for like 3 seconds then suddenly, we get the message "No internet access" and "limited internet access" on our XP and windows 7 laptops. On the windows 7 it shows a small yellow triangle symbol with an exclamation mark on the bars too.So I tried turning off firewall, and resetting router and all that, plugging it into modem (which I'm doing now) and have narrowed it down to something to do with the routers settings, because it works fine through the modem. and its nothing to do with the router being in the other house because we even brough the router back and its doing the same thing.I dont understand why something would go wrong just by unplugging the router because nothing was changed. Anyway I tried johnwills steps and here are my results from both my XP and windows 7,

I'm inclined to think this is a bad router but just wanted to run it by everyone. All of a sudden I can't get into the router interface or ping it, but the internet still works. If I power cycle the router, then I can get back into it.
View 2 Replies View RelatedI have a Gateway desktop computer easily connected to an internet providing modem from Comcast. I have tried to set up a wireless router so that I can connect my Sony laptop, but have not succeeded. The laptop has a built in wireless device that easily connects to other wireless routers such as the one in my parent's house or my sister's house, just not the one in my own place.Connecting the laptop to the wireless router seems to be accomplished. The laptop says it has been connected and signal strength is "very good" but web browsers are unable to connect to the internet. I have tried three separate web browsers (firefox, internet explorer, and google chrome) and still nothing.The router seems to be working fine. It is a netgear N150. Power is on and the desktop, connected through the router, and then into the modem, connects just fine. This tells me internet connection is alright through the modem, right? I have tried numerous times to turn off the power and wait, then try connecting again and have not succeeded. I have done this at both the modem and the router.
I have gone into the laptop's ip settings and have marked the ip and dns addresses to automatically receive. I believe a great deal of the problem is that the laptop is not receiving any wireless bytes being sent out. I've seen the sent bytes between 84 and 378 (is this low?) but nothing is received. If I could figure this part out I feel I'd know what's wrong. The IPv4 IP address is 192.168.1.3The IPv4 Subnet mask is 255.255.255.0The IPv4 default gateway is 192.168.1.1The ipv4 DHCP server and DNS server read the same number as the default gateway.Not that I know much about these numbers. Every time the problem is encountered I strike the "diagnose" tab but to no avail, as though the laptop refuses to even try to diagnose. I have attempted to get new IP settings and reset the network adapter but the laptop, and though I receive a "repairi
I've just built a PC for my brother for mild gaming and browsing and placed it in the living room, the only issue is that after buying and renovating new home, our pops wont allow us to poke holes around his big investment and use Ethernet for connectivity.Having win 7 x64, I've come down to purchasing a PCI Adapter that has been noted to work well with win7 - WMP600N... Now the problem is I am unsure which router to purchase to make it work well.
View 3 Replies View Relatedwe hadn't have the WEP key on our Linksys wireless router, so we decided, about a month ago, that it was a good idea to lock our wireless connection. So we did. For a couple of weeks, everything worked just fine.But then we bought a new printer, which happened to be a wireless network printer, and in the process of installing it, we mistook the reset button (I think) on the router for some other button and ended up resetting the router. When we did that, we undid WEP key, thereby unlocking the router. Then, we locked the router again, at which point one of our computers--which happens to be mine--ended up not working. All other computers and phones and iPads work just fine, but this one laptop of mine just doesn't work (with respect to wireless internet connections, of course).
- pressing the reset button on the router again. It kind of works. The internet works for about five or ten minutes (which is unbearably annoying because I have to reconnect it every five minutes), but my computer somehow disconnects itself from the internet connection. Also, although the internet technically "works," the wireless network icon thing on the bottom right of the screen has an "X" on it, which I thought meant the internet is not working, but it apparently doesn't, because my internet is working now. And, if I click the icon, it says that I'm not connected, but, again, the internet works. (for about 5~10 minutes, if I unlock the router)
- changing the internet protocol information (I don't think it does anything, but.)
- changing the wireless internet connection property to WPA, WPA-PSK... everything.
*All computers in the house have wireless internet connections but mine.
*When I reset the router, the internet works, although the computer says it isn't connected, and it disconnects itself every 5 or 10 minutes.
I have my internet coming from my DSL modem (of course) and running into my wireless router. Once it is in the router I can't get a connection, period. Not even through any of my router's ethernet ports. This wasn't the case until about 3 o'clock yesterday. If I unplug the cable from my wireless router and plug it directly into my computer it runs fine. If I run it through my Micro-Cell tower and into my computer it runs fine. But if I plug it into a router it won't work through Wi-Fi or Ethernet. I have tested the connections of all the ethernet cables I am using. Figuring it had to be a problem with my router (since it was working earlier and the connection only disappears when plugged into it) so I bought another, same problem. What else could it be? PS: I'm using both a MacBook Bro, a PC, a PS3, and a Nintendo 3DS and none get a signal from the wifi. I always keep the PC hardwired through the ethernet ports on the router and use the wireless for everything else

The thing is when i connect the modem to my laptop via ethernet cable internet works but not when i connect the cable to the router even though this worked before. actually a few hours before. so i dont know whats happened to my router since clearly the problem is in there. the modem has lights for PC Cable DATA and POWER. The lights to all of them blink when i have connected the modem directly to laptop but the PC light is non existent when i connect it to router. hence i get no internet access. the routers power is on so i dont know what the prob is ive rebooted it a few times but to no avail.

-working fine until I unplugged to move it and plugged it in
-verified with tech support the problem is not physical
-right now, am hardwired to the router, which is hardwired to the cable modem, and connectivity is fine through hardwiring
-no luck through wireless - this is the error message I get:

Our home school's having trouble attaching a wireless router to my XP PC's ethernet port.Our donated vintage Macs and XP machines are tied to the internet via a cable box's wireless router. Works just fine. Now I wish to boost the signal to a building beyond the local area by attaching a wireless router to a Dell 260 running XP. This router's IP is 192.168.11.1 (ON) and 192.168.11.100 (OFF), and I've spent hours with the Connection Wizard thing on XP trying to create a ethernet path to the router but I can't find a configuration that states an ethernet path or channel. The modem lights normally and other machines can pick up and connect with its signal but there's no real transmission, the receiver machines getting:Firefox can't find the server at [URL].Check the address for typing errors such as [URL]instead of [URL] If you are unable to load any pages, check your computer's network connection.If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.Ironically, the router works just great on the Macs, which has both Airport on to receive signals from a cable TV wireless router and also has its shared Ethernet connection on, and the ethernet side requires no IP configuration like it seems you must on the XP's internet connection page. The router in question just plugs in the Mac and transmits just fine. I would use the Mac for this purpose but I really wish to use the Dell.The Dell's current network configuration after many trials:
Wireless Connection 3
LAN / High Speed Internet
Connected, Firewalled
802.11n USB Wireless LAN Card
IP 169.18.2.7

Oddly, the Mac's Network panel states: "The cable for built-in ethernet is connected, but your computer does not have an IP address and cannot connect the internet." Yet it does!
I've just got my first ever router from talktalk, DSL 2780 which works fine but I still can't connect to the internet. I called the helpline and they checked my broadband connection is working fine and all the cables are correctly connected. Then she got me to open Internet Explorer and type in 192.168.1.1 but it brought up a page saying that it couldn't be displayed and there was no internet connection, so she told me to make sure the Work Offline option wasn't ticked and did something else in Tools Internet Options and then typed those numbers again but it still didn't work.
View 11 Replies View RelatedIntalled a new router (Linksys Cloud 1200) yesterday. Immediately after that the 2 computers that were connected to the network could no longer access the internet. My laptop and my ipad can access the internet wirelessly. The laptop which was not connected to the network when I connected the router can access the network both wirelessly and wired. Printers attached to the network will print without a problem.Finally I took an old computer out of storage (running WinXP) and hooked it up to the wired network. It too has no problems accessing the network. So have to assume the issue is a software issue with the two computers that were hooked up to the network when I changed the router.I have read the posts here - I did a stack reset on one of the computers but no luck. I removed Norton 360 and Team Viewer which in other posts people said they had issues with...to no avail.
Since I dont have a wireless connection to the 2 computers that cannot access the internet - I cannot download TSG SysInfo. However here I did copy the ipconfig lines below from the desktop thats not responding. [code] Was working fine until I replaced the router. I tried going back to the oldrouter (Netgear) same issue - no wired internet connectivity.
this computer was working on this router no problem. computer crashed and noiw computer is fine i connected it to my cable from ny desk top comutyer and works fine. It just cannot hook up to the wireless connection?

I have Charter cable with Motorolla SB6121 modem. I've reset the modem, rebooted everything, cloned my ip address, all several times .......but still no go.

how this switch module works in 2911 router? I have two 2911 routers in HSRP configuration for redundancy with crossover cable between switch modules. OSPF running on routers.If active router loses its power and then comes back again, it boots first, its internal link to switch module comes up and it starts to forward packets to switch module. The switch module starts to boot only after router is ready. So I have outage of about 3-4 minutes. For our real-time applications it is way too long.
any way to start booting of the switch module before router gets ready?I understand I can boot it manually, but it is only after router is ready. Only way to get around it I found is to disable internal link and use router interface to connect to the switch module.
I'm trying to set up a wireless network for my parents. I have a Belkin Play N600 router (model F7D8302) that I'm trying to hook up to an Acer desktop running Vista. The modem is a Siemens Speed stream 4100. I have a cable going from the ethernet port of the modem to the modem port on the router. The pc is connected to one of the other four ports in the router. The wireless works fine, but I can't get the wired connection on the desktop working. The Internet light on the modem is not on, but the modem works fine when connected directly to the pc. I've tried power cycling and resetting everything, but it's still not working.

So I think the router may be causing it, could it be the settings? Even though there at default.
Hardware: Modem-Motorola SBV5222 Router-Linksys E2000(Cisco brand name? I didn't buy the router) I use a PC with windows xp with sp 2 and 3 installed.Problem: I can use the internet just fine when I am connected to the router, my pc is connected directly to the router via cat 5 but when I directly connect to the modem I get limited to no connectivity. I'm not using a proxy server and before the router was set up(I live with roommates who set up the wireless network.) I could connect to the modem just fine. I can't repair the connection since it seems to be unable to renew the ip address. I've also tried to manually configure my ip address though I'm sure it wasn't the issue.I've racked my brain to think of a simple solution and it doesn't seem one is apparent and I'm almost sure it's something to do with xp and I'm not so great with software.

The router is connected via ethernet to a dead computer: a 7 year-old Dell desktop that will boot up but shut down right away. I have been able to connect multiple laptops wirelessly to this network. I thought an ethernet connection was required in a home network such as mine? The cable has been plugged into a dead computer for several months and frankly I'd like to get rid of the desktop. What exactly is the ethernet requirement - just to be plugged into a port? Could I theoretically just yank the ethernet card out of the desktop and use it instead of the whole dead system?
