What do I connect 2 switches with router

Hi, Everyone. I have this trouble and would like to get help.
Here is my situation. I have one Verizon router in basement. I run the ethernet cable from router to one room in first floor. I have one Linksys switch in this room. This is switch 1. I have 2 computers connect to this switch, all working well. I then, run the cable from this room to second floor. If I directly connect this cable to computer in second floor, it works well. But, I have more computers in second floor. I bought another Linksys switch, switch 2. Here is my trouble, if I connect the cable from switch 1 to switch 2, and connect computer to switch 2, I have trouble.
All lights are on and stable, and seems all correct. But, from computer, I cannot see any connectivity, even I set up the IP address manually, it will not connect.
I called Linksys supporting center. First, I was told that I should put cable in Uplink in Switch 1, and port 1 in switch 2. I did so. Does not work. Then, I was told that I should put cable in port 1 in switch 1, and port 1 in switch 2. I did so. Does not work.
I am quite confused. In concept, I think, my configuration should work well. But, why not? Please advise on 1) If this configuration should work? 2) If should work, how can I do?
Thanks a lot for everyone.

Thanks for your inputs. Here is the exact configuration.
Router: Verizon Action Router. It has 4 numbered ports.
I run straight cable from router to room 1 in that I have Switch 1.
Switch 1 is EZXS88W (version 3.3). I put cable from router into port 7. This switch works very well. NO problem at all. All ports are working well. So far, I connect 3 devices into this switch. None has problem.
I then run straight cable from switch 1 to another room. There I have swtich 2. It is EZXS55W (version 4.1). I put the cable into port 1 of switch 2 (actually, I tried all ports). Then it does not work. No connectivity at all. I call the cable from room 1 to room 2 as Cable A (it is a straight cable). If I put cable A directly into computer, it works well. But, if I put into switch 2 (any ports) then connect computer to switch 2, I have no connection.
This is exactly my situation. What is the problem? What is the solution?
EZXS55W afaik is "smart port" so you can put that into any of the numbered ports ( I prefer port 1), have you tried switching these two "switches" to see if the autosensing feature of the 2nd switch is not broken?
Also, what IP address are you getting on the computer you connected on the line going to the 2nd switch? It may be on static ip, but if not... can you try connecting that line back then set a static IP on the pc to check if it at least pings the first set of computers and router??

Windows 7 Update Internet Connection Issue with Router

I updated two of four toshiba laptops with Windows 7 and installed Toshiba's wireless adapter driver for Windows 7. The adapter connects to the router and I can access all resources on my home network, however, Internet service is not available on the two laptops with the Windows 7 update. After disconnecting and reconnecting 7-10 times, the Internet Service connection does not drop. The other two laptops and two desktops that are not running Windows 7 do not have this problem. Is there any known issues with lynksys wireless routers and Windows 7?

When your Windows 7 machine is having problems, can it ping the following IP addresses:
127.0.0.1 (local loopback)
192.168.1.x - the DHCP IP address it was issued by the router
192.168.1.254 - your router
8.8.8.8 - Google DNS out on the internet

Connecting Switch to Router

Greetings,
I have a 3750 switch that has several VLANs defined on it. I also have an 1841 router that has the same VLANs defined (they are numbered the same).
At the moment they are connected and I am able to browse from a host connected to the default VLAN. I would like to connect the switch to the router and test the VLAN functionality.
Where do I start? On the switch or on the router
When I tried to complete the LAN wizard on the router and assign the default VLAN to the routers Fa0/0/0 port, it caused the switch Gi port to err-disable due to bpduguard.
TIA
Charlie

Yes I am connecting the switch and the router via Gi1/0/1 on the switch and Fa0/0/0 on the router. The Fa0/0/0 is one of 4 ports on the router switchcard HWIC.
Is there a configuration document for this type of setup?
Also, the switch did shut down the port with a reason of BDPU... so it seems likely that the switch shut down the port because the router was sending bpdu's. What is the risk in shutting down bpduguard? Do I need to shut it down on the router switchcard as well as on the switch?

Trouble connection Laptop with Router

Linkysys Cisco Wireless-N WRT160N, My connection is fine, My sons laptop will not show my router in his connections. At times it will, and then at times it won't. Most of the time when it shows, he can not connect. We both have Network Magic, when having Network Magic try to fix the connection it never works. I have added his laptop on my devices. He has no problem connection with his Xbox. just the laptop, I am at a loss of what to do. Thanks

I assume that you are loosing both your wired and your wireless connection at the same time. Is that correct?
The most common cause for this is peer-to-peer (P2P) software. If you are running P2P software, go into the program and reduce the number of connections that the program makes.
If this is not your problem, please give more details. Also, please include your router model and version, ISP, the make and model of your modem, and how your system is set up.

Internet connection error with wrt54g

i have dsl with a 2wire modem. i connected the network cable from the modem to the 'internet' port on the router and the network cable that comes with router on port '1' and the other end of cable to the computer. when im installing it and the router is checking for an internet connection it says "router was not able to connect to the internet. turn off modem then on again and try it again" and it still doesn't work.
in the router the internet light is on so i dont know wats wrong. need help badly because im getting tired of this

it didnt work, once i did everything i opened the internet and it it showed an error page. this is what i did connect modem to router on the 'internet' port, connected other network router from computer to port 1, then i reset the router by pressing the reset button for like 10 sec, the disconnected the power adapters to both divices for about 20 sec and plugged them back in and when i opened the internet it didnt work. did i do anything wrong?

Branch office setup with L3 switch and router with IOS security

Hello,
I am in the process of putting together a small branch office network and I am in need of some design advise. The network will support about 10-15 workstations/phones, 3-4 printers, and 4-5 servers. In addition we will eventually have up to 25-30 remote users connecting to the servers via remote access VPN, and there will also be 2-3 site-to-site IPSec tunnels to reach other branches.
I have a 2911 (security bundle) router and 3560 IP Base L3 switch to work with. I have attached a basic diagram of my topology. My initial design plan for the network was to setup separate VLANs for workstation, phone, printer, and server traffic. The 3560 would then be setup with SVIs to perform routing between VLANs. The port between the router and switch would be setup as a routed port, and static routes would be applied on the switch and router as necessary. The thought behind this was that I'd be utilizing the switch backplane for VLAN routing instead instead of doing router-on-a-stick.
Since there is no firewall between the switch and router my plan was to setup IOS firewalling on the router. From what I am reading ZBF is my best option for this. What I was hoping for was a way to set custom policies for each VLAN, but it seems that zones are applied per interface. Since the interface between the router and switch is a routed interface, not a trunk/subinterface(s), it doesn't seem like there would be a way for me to use ZBF to control traffic on different VLANs. From what I am gathering I would have to group all of my internal network into one zone, or I would have to scrap L3 switching all together and do router-on-a-stick if I want to be able to set separate policies for each VLAN. Am I correct in my thinking here?
I guess what I am getting at is that I really don't want to do router-on-a-stick if I have a nice switch backplane to do all of the internal routing. At the same time I obviously need some kind of firewalling done on the router, and since different VLANs have different security requirements the firewalling needs to be fairly granular.
If I am indeed correct in the above thinking what would be the best solution for my scenario? That is, how can I setup this network so that I am utilizing the switch to do L3 routing while also leveraging the firewall capabilities of IOS security?
Any input would be appreciated.
Thanks,
Austin

Thanks for the input.
1. I agree, since I have only three to four printers, they need not be in a separate VLAN. I simply was compartmentalizing VLANs by function when I initially came up with the design.
2. Here's a little more info on the phone situation. The phones are VoIP. The IP PBX is on premise, but they are currently on a completely separate ISP/network. The goal in the future is to converge the data and voice networks and setup PBR/route maps to route voice traffic out the voice ISP and data traffic out the other ISP. This leads up to #3.
3. The reason a router was purchased over a firewall was that ASA's cannot handle routing and dual ISPs very well. PBR is not supported at all on an ASA, and dual ISPs can only be setup in an active/standby state. Also, an ASA Sec+ does not have near the VPN capabilities that the 2911 security does. The ASA Sec+ would support only 25 concurrent IPSec connections while the 2911 security is capable of doing an upwards of 200 IPSec connections.
Your point about moving the SVI's to a firewall to perform filtering between VLANs makes sense, however, wouldn't this be the same thing as creating subinterfaces on a router? In both cases you are moving routing from the switch backplane to the firewall/routing device, which is what I am trying to avoid.

Using Catalyst 3550 Switch with Linksys Home Router and Cable Internet

I've about pulled what little hair I have out of my head on this one, and need some configuration help.
I have a Cisco Catalyst 3550 switch with five Windows 7 desktops, an Avaya PBX and five Avaya IP phones attached. All of these devices are on a 192.168.0.0/24 subnet, and are communicating properly. I will refer to this as network # 1. I also have SEPARATE network, we'll call network # 2, using AT&T ADSL service and a Netgear 4-port/wireless router/ADSL modem combo device, which is functioning properly with a couple of other Windows 7 desktops over its own wired Ethernet network, using DHCP, and also on a 192.168.0.0/24 subnet. I thought it would be a simple integration, just plugging one of the 3550's ports to one of the DSL router's ports, in order to give the five Windows 7 desktop computers on network # 1 internet access via the DSL modem. Guess I was wrong. When I connect the two switches together, although I get a good connectivity (green lights on both ports) and am able to ping the DSL router's gateway address (192.168.0.252) from network # 1's computers, the computers on network # 1 cannot access the internet. Also, the working computers on network # 2 lose their internet access as long as the two switches are connected together. I am not a Cisco guru, but there's got to be a way to make this scenario work. Can someone provide me with a 3550 configuration that will allow me to extend my internet service from network # 2 on the DSL router to my 3550 switch and their computers? Here's what I am looking for:
INTERNET ---> ADSL MODEM ---> NETGEAR ROUTER ---> CISCO 3550 SWITCH ---> NETWORK DEVICES WITH INTERNET ACCESS

The Netgear router is probably what's doing the natting. Is the 3550 configured for routing or is it straight L2? If you have the 3550 configured as L3, then it's going to be easy to do what you want. Just add a static route on the Netgear to point the subnet that it doesn't know about to the 3550. For example, if the Netgear is addressed at 192.168.1.1 and the Cisco 3550 is addressed at 192.168.1.2, but it also knows about the 192.168.0.0/24 (separate vlan), then you would put a static route on your Netgear for 192.168.0.0/24 to go to 192.168.1.2.
The way that I would do it is to create a separate vlan on the 3550 and assign an address to it. Once you do that, make the port that the other switch connects to an access port of that vlan. (It would need to be on the same subnet as the existing equipment.) All of your devices would use it as a default gateway and then you would do the rest as above. You could also use RIP between the Netgear and Cisco if you can't do static routing.

Best Pactice for Connecting ASA to Catalyst Switch with Mulitple VLANs

Hi all,
Have the following network topology that was in place when I started the job (See attached pdf). Am thinking it might be better if I could eliminate the Cisco 2811 router and connect directly from the ASA to my 12 port fiber switch (192.168.7.1). In my thinking this would eliminate an unnecessary piece of equipment and also give me a gig link to my ASA as opposed to the 100 meg link I have now with the old router. The 12 port fiber has links to most of my IDFs and is acting as my VLAN gateway for all inter VLAN routing.
Is my current topology ideal or would I be better served to remove router and connect directly to the 3750G-12s Fiber switch or my Master Switch (192.168.7.4)? Only thing I don’t like about direct connect to Master switch is that it takes scheduling a major outage for me to reboot it. However, if that is best practice in this case, I can live with it.
It appears the 12 port fiber cannot have IP addresses assigned directly to Ports, only to VLANs. So would I have to create a separate vlan for my ASA and assign IPs to the vlan on each end of the connection?
I have read some suggestions that say it is better to terminate all VLANs on the ASA. So as I understand that would require creating subinterfaces on my ASA LAN port and assigning each subinterface to its own VLAN Inter VLAN routing would then be controlled by ASA.
Does not seem practical to me as I have about 15 VLANs total. Not showing everything in the drawing.
Guess my main question is “What is best practice for topology and routing in my scenario?”

Hi Mcreilly,
You should be able to assign an ip address on cat6k sup720 if you are running native ios on sup 720.
If you are running catos then you will not be able to do that and you can have it configured as trunk and connect to the router.Also I do not think that you need subinterfaces on router and trunk on switch because your cat6k with sup720 must be doing intervlan routing between vlans.
You can just connect it on some port on any vlan and same subnet ip address which you have it on msfc for that vlan you can assign on the router interface and anybody want to go out via t3 link will get routes on sup720 and move out via router vlan.
For suppose you do not want the router to be part of existing vlan you can create one vlan on cat6k sup720 and assign one port to that new vlan and connect the royter to that new vlan port and then create logical interface on msfc for that new vlan and assign an ip address range on that logical vlan and same subnet ip address range you can assign on router physical interface.
Any one from other vclan get routed on sup 720 msfc and will move out via the vlan on which you have connected the router.
because you have only one router you will not be able to maintain box level redundancy by which i mean if the router goes down t3 will be unreachable.

Internet connectivity issues with SA 520W router

Hi,
We have configured Cisco Small Business Pro (SA 520W) in a small office and all computers are connected with wifi. We are facing following problems:
1. Computer is connected with network and 100% signals available but there is no internet. After repairing network from computer or sometimes rebooting computer fix the this problem. What cause internet connectivity problem?
2. Sometimes computer is connected with internet and everything work fine but suddenly there is no internet. May be internet come back again after 2 minutes etc. Strange behavior.
3. Sometime there is no internet connection even after trying all possible tuneing but internet connection become alive again if we reboot router.
All these problems appear randomly on different computers. Can anyone tell what's the reason of all these problems and how can fix it?
Thanks.

I have the just similar problem since few days , for long time I have no issues with wireless router
I have five static IP addresses I am using 1 static IP for the Router and other for the internal use
I though it was my inter provider technical issue,
The internet is working through provider gateway router but not through a Cisco SA520W
some times it works some time it wont resolve host name, internal LAN works perfect ,but internet drops packets and it is very slow
If we dynamically setup the router, it works but not for the static IP address
my old configuration is not saved , reset to factory defaults even then it did not work
I do have 24 port cisco switch when I login there is no gui console just blank blue screen with text boxes
I appreciate some can guide.
I believe we need the update firmware on both devices .I appreciate for the help
Thanks

I have just update my MacBook to Snow Leopard 10.6.3. Unfortunately I can not now connect to the internet. I have a time capsule that is connected to a router. This is working with other devices but if I try to connect with the MB everything stops?

I have updated my MB to Snow Leopard 10.6.3 - I know this means I am a little behind the times but the problems I am now having seem to justify my reluctance. Now am unable to connect to the internet! I use a time capsule connected via a router. Everything is still OK with every other device (PC, I phone, Ipod) in the house so I know the "Network" is still enabled and there is no problem with the ISP. Strangley whenever I boot up the MB it appears to freeze the network such that the other devices also will then not access the internet. To regain access I have to turn off the MB and reset the router. Any help gratefully recieved as I have tried some of the ideas i have found in the internet but nothing is working. Thanks.

That's odd.
Try this: Unplug your Time Capsule and your router. On your MBP, click the Wi-Fi icon and select "Open Network Preferences".
Click the lock icon to authenticate, then click the "gear" and select "set service order". Wherever AirPort (or Wi-Fi - I forget what Snow Leopard calls it) appears, drag it elsewhere in the list. Click OK, then Apply, then power up your router and TC.
If that doesn't result in any change, repeat the above but try making the service(s) you do not need "inactive".
The purpose of this is to reset or at least change your Network Preferences, which somehow got confused upon upgrading to SL.

My MacBook Pro persistently will not connect to my wireless router. The message "connection timeout" appears. What is a connection timeout and how can I fix?

Hi, I want to use my Capsule just as a back up via wireless. How do I set this up without connecting it with an ethernet cable to either a router or the iMac??

Hi, I want to use my Capsule just as a back up via wireless. How do I set this up without connecting it with an ethernet cable to either a router or the iMac??

I misunderstood what Time Capsule is and had hoped for a wireless backup device that didn't have to be connected to the router.
The TC is a wireless backup device.. it does not need to be connected to the main router..
The problem is the computer.. not the TC.. the computer has only one wireless card.. if your current internet is by wireless.. then you must choose.. internet or backup.
But my other suggestion will work.. get a wireless USB stick compatible with Mac OS.. there are plenty and cheap.. since you are in the same room as the TC they will work fine.. plug it in and load the driver.. taint hard.
You should do the first backup by ethernet though.. wireless is too slow.. once you have that, you will do fine.
Search ebay for wireless n usb.. Mac compatible..

As you can see.. they are getting smaller and neater.
I have no idea if it works .. haven't tried one.. but I have used USB wireless stick on the Mac to overcome this issue.
You will need to set static IP .. not hard but you need to set specifics if you do buy one post again for the setup.
