Cisco WAN :: C3750s Finding Best Solution For Small ISP Network
Aug 16, 2011
Want some input on what will be the best solution in this scenario.Basicly this is a small ISP network.In each area, behind the C3750s, there are som DSLAMs, access switches and wireless base stations.Some of the clients need L2 connections across the network, as they have several offices.The C3750s are all Cisco WS-C3750G-12S-E.The management networks must be isolated, but be able to reach each other.What do you think would be the best solution realising this network, based on the awailable hardware?

have to build a solution for a network of around 150 users from the same building with about 50 users per floor. They are all having an workstation with windows 7 prof (about 75%), windows XP home edition (about 20%) and windows xp prof (5%). They are working in Autocad and I need a server on which I have to put windows 2008 server with AD and will have a role as fileserver.I need to know what are suppose to be the minimum hardware requirements for this server. Having not too much IT experience I need to know if the users that have windoiws xp home edition need to change their OS.

Currently we have the Synology DS212J system and that backups to the cloud as well.The problems are not being able to access it remotely easily, space, and the cloud integration is too slow and not reliable enough.
So we need a larger network, that is easily accessible remotely and backs up regularly. The main thing that will be taking up a lot of space over time is a lot of artwork files. A lot of these don't require on site network access, so if we had 30% storage local and the rest remote that would be fine, everything needs to be accessible remotely still though.
One thing I was looking into was Amazon storage gateway, it is pricey though so I'm wondering what other options there are. URL
Perhaps a larger NAS with different backup would work? It needs to run more seamless than the cloud is. We used Jungledisk before this which worked great with only a few users but we are now at 10+ users and growing.

I have a question for Cisco Cat.2960-s Flex Stack switches which are installing on our sties. Two of 2960-s Stack switches as access switch and two of Cisco ME 3600X Series as distribution layer switches are to be installed in our sites. In case of two stack switches, One is will be a Master and the other one will be a member logically, as you know. So, if the master fails, the other one automatically becomes the stack master following a well-documented election process.
Now, it is my question. How long takes to be a stack master from a member switch ? I cant find it on white paper of Cat.2960-s flex stack .
And also, I heard that sometimes a member switches don't election process when the master fails as a result, all stack members become
a panic. Is that really right ? In addition, I heard that the stack switches have many troubleshooting points than stand alone switches.
I really wanna know if the stack switches are good solution for resilience of huge network site. I'm waiting an answer from those who have experience of maintenance or installation.

I have a c890 switch is a default gateway for the lan behind it. The router is configured with bgp for 2 providers and local network is /24 rout able network (92.224.1.0/24). I think bgp is configured correctly because I can ping any ip from the router (92.224.1.1), for example I can ping 8.8.8.8.
The problem is that I can not ping anything from the local network, from example I can not ping 8.8.8.8 (Google dns) from 92.224.1.2.
92.224.1.2 has as default gw 92.224.1.1.
92.224.1.2 -> 92.224.1.1 -> BGP 2 ISP's

I'm involved in setting up a new office for a business that's just starting out. I have some computer experience but not a whole lot in networking and security. We just have 3 people that will be working in the office and we need a way to store/backup/share files on the network as well as a way to access them remotely if need be. Our internet service is going to be providing us with a static IP. I was thinking that we could use an NAS with RAID 1 attached to the router, which is in turn connected to the cable modem, but I'm not sure if this is secure. Do we need some type of hardware firewall in between the cable modem and the router to protect us from the outside?

I've been tasked with redesigning a small network (15-20) including wireless. Cisco recommends the RV220 as the entry point Firewall/Router/Wireless and researching there are apparently some good and bad sides of having everything all in one unit depending on who you ask. The other option would be to get a dedicated Firewall/Router and then run the wireless on a seperate device(vlan). I'm fine with either solution but my main concern is performance on the physical connections as well as reliability with the wireless having good range and not dropping or having to reboot the router continuously. Behind the router/firewall I will purchase one of the Cisco 24-port gig switches for physical connections through the office. How to get for the router/firewall/wireless setup? Budget is not a problem although I don't want to pay for something that is overkill for 10-15 wired workstations and 5-10 wireless including a guest wireless.

I would like to setup a simple VPN on a small network, nothing special, just to provide access to some simple resources on the network from anywhere. Since I'm not a Cisco expert, I was advised to user a 861 router, but I just can't seem to get the VPN working on this device.
I've placed the router behind a modem and did some basic configuration. Hosts who are connected to the modem (on the Vlan side) can access the internet and can setup a VPN connection to the router. A VPN connection from inside the network is worthless, but I just can't get the VPN working on the FastEthernet4 connection.
Any VPN config for a 861 router for this situation? Or how to configure this device as a VPN server?

Three weeks ago I moved all the APs at one of our sites from WISMs (running 5.2.193) over to a pair of 5508s (running 7.0.220) and everything appeared to be fine through testing and implementation. We've got about 400 devices on this network and almost everything is working without issue, except for about 10 Honeywell Dolphin hand-held scanners that our distribution department uses. On occasion when the users go to use them, even when sitting 15 feet from an AP, the device will kick out an error that the "wireless network was not found - please move closer to an access point or return to cradle".
As much as I would love to say it's a device issue, they said the problem started the same day I moved the APs to the new controllers (they gave me the date they started experiencing the issue, I was able to link that back to the date I made the move). They worked without issue on the old controllers / code and, for the most part, both old and new controllers are configured similarly (except for enabling a few new feature that the new code supports like client-link and band-select). These are b/g clients and I did diable all .11b data rates when moving to the new controller. Also, this happens in multiple locations, not just in the receiving / distribution area.
Lastly, I'm at my wit's end on this. The issue is totally random and when they are having an issue I can't even see the device trying to connect (by debugging the client on the controller). One suggestion I've made is that we may need to upgrade the device firmware, but I'm not sure why it would work with the old controllers and not the new. I guess the worst case scenario is that I can move the couple APs they have in the receiving area back to the old controllers to see if the issue continues.

I just took a position and never had to work with networks that much before. Our lan is very slow and trying to figure out why. We have verizon business class 3 t1 lines dedicated 4 M. When I do a speed test we get about 4.05 average and 4.23 down. We have 11 computers on the network connected to a Dell power connect 2716. We have Two network printers and that is it. We are having problems with it being very slow when connecting to a share on the server or using RDP.

My current set-up is: my laptop connects to the coaxial outlet with a cable so I can access the internet. So I can't really bring it somewhere else since the cable is short.
Now, I am planning to buy 2 more computers and a printer. The printer will be shared by all 3 computers. what else I need to buy (modem?? wireless router??) and what type. I also request that you let me know how to set it up. Of course, I will follow the manufacturer's instructions.

I work for a small business of five computers. We have a wireless network for internet traffic, and a wired network for file sharing. The wireless network works great for using the internet, but we are having trouble with the wired network.The issue is being able to communicate with all of the computers on the wired network. The ability to speak with all of the computers on the network is hit or miss. Generally, computer A can speak with computer B, C, and D, but D can only speak with A.

I am buying a router with wireless soon and i am setting up an ADSL account.I only have one computer that will connect to this router.The router will be based in the living room area where the phone line is.My room (where the computer is situated) is quite far from the living room and i am not keen to drilling holes through roofs to wire some LAN cable.My plan is to use a wireless dongle in my pc to connect to the router for internet. Will this affect the speed of my downloads off the internet at all? will it be the same as if i was using a lan cable?I know file sharing over the network via WAN is slow but will my internet be?

I have been tasked with the technology update of our office and have have MAJOR questions which I hope can be answered here, so here goes;
First a little history, I have an electronics degree and a certificate in computer technology, so computers are not something new to me, however networking IS.I have a VERY LIMITED budget to work with, which I'm sure is not unheard of before, with the following equipment already available:
1 MFP currently on lease connected via network
3 totally junk PCs running 3 different versions of Windows from XP to 7
A DSL internet connection
A wireless router
A wired 8 port switch
What I would like to do is begin with a basic server, 7 clients, shared internet on all machines (including external via login), An MFP, at least 1 NAS for data storage, 1 NAS for backup of all drives.

He currently has 1 server, and 11 workstations, he also has a network switch that we will be replacing.We have picked out a Dell server, running Windows Server 2008 R2 that will be used as the main file server, as well as the domain controller. Where I seem to be confused is on setting up the networking component, particularly how the machines will get IP addresses. As mentioned, I will be purchasing a new Ethernet switch, in order to get the fastest LAN speed possible; I have selected the Dell PowerConnect 2816, which is a 10/100/1000Mbs switch. My question is, will I be letting the switch handle the IP's/DHCP or would I be better off, setting up the server for DHCP? If so, do I also setup the server as the DNS server? From what I am reading online using the server as the DHCP/DNS server gives us more management capabilities and is more "secure". As a test, I loaded Windows Server 2008 R2 on a home machine and played around with this. I got a bit lost on the DHCP and DNS setup and it appears that one needs a Static IP from your ISP in order to setup your serve as the DHCP/DNS server for the domain. Is this correct? I haven't been to his office yet to check out all the existing equipment, is it safe to assume that his ISP provides a router or whatever is needed to feed the switch?

What are the best network engineering practises for a small/medium sized office?Currently I have set it up like this:The top floor has all the sales people, each desk has a hub underneath which connects all computers at that desk together, and the hum is connected to a switch under the floor. There are about about 8 desks each with about 4 computers, so 8 hubs.They all go into a 10/100 switch, which is then connected to an 1gb switch on the bottom floor via a 1gb port on the top floor switch, via a cat6 cable.We then have internet > modem > router > the 1gb switch. Our main server is also connected to that switch along with all the computers for the ground floor, except these computers have 1gb switches under the desks instead of hubs. The main server is the DHCP, DC, DNS and file server. We have also setup another server which acts as a backup DC and is also a DNS server.Is there anything wrong with this configuration? We have been having problems with the router losing connection to the internet and warnings on the main DNS server.

We have a small download limit every month and keep ramming into only days into our billing period. I am trying to identify the culprit but need to find a way to log the traffic of individual IP address (which are all static) on the network to figure out where all the bandwidth is going. Any (preferably free) application that will allow me to monitor this?
Network Infrastructure:
Modem connected to NetGear N2000 (older model) Router 192.168.0.1
Family Desktop - 0.2 (Ethernet)
My Desktop - 0.3 (Powerline Ethernet)
Brothers Laptop - 0.5 (Wireless)
My PS3 - .0.30 (Wireless)
iPods - (Wireless)
Router only tells me when someone is on and can track total network traffic usage not individual hardware.

3 Computers 2 using vista - 1 using XP. Printer is a HP 2727nf. Will work for a couple of jobs then receives an error code and will not print anymore for any computer. Only a hard reset of turning the printer off and clearing out the queue will print the job that was getting stuck. Wondering if anything can be done so error code won't show up and we can get this printer to run smooth again. PS we have another HP printer that works fine on the network.
