All the wall jacks are terminated properly with RJ-45 connectors. At the junction box outside I have connected the 4 pairs to their color equivalent.I have also purchased a "patch board" to terminate and combine all the wiring in one spot.Once all the wires are connected, I tested the wiring (Sperry cable tester).It tells me there is a short in 1-2. I've made it this far and I'm really close, I just need to know which pair I need to focus on. Is pair 1-2 Orange/OrangeWhite, Green/GreenWhite, etc?

View 4 Replies View RelatedWe have a pair of N7K distribution switches connected to a pair of N7K Aggregation switches.We run vPC on both pairs of n7k's.
-n7k-d1 has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC1)
-n7k-d2 also has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC2)
My problem is that Spanning-Tree is blocking PC2 and all traffic from n7k-d2 is traversing the Peer-Link before reaching the Aggregation layer. Is this the best design for connecting two pairs of n7k's with vPC or if a better design would be to connect all 4 links into the same Port-Channel and vPC?
I've got a router on which I run a backup/media/print server, a couple of computers and a voip box. My router has only four ethernet lan sockets which are thus all occupied by the above, but I need to attach at least one further device b
Secondly, could a splitter such as >> this one << do the job? I'm guessing this basically split a single 4-pair ethernet connection into two 2-pair ethernet connections.
I have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:
- The E3000 has a 192.168.0.6 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a 192.168.0.7 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the 192.168.0.1 as the gateway and web-interface
Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.
- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the 192.168.1.15 and 192.168.1.16 IPs and ports 9001 and 9002.
- The printer is connected to the E3000 and I have manually assigned the IP 192.168.1.30.
Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as 192.168.0.6 (E3000 IP), Internal Port 0, Public Interface IP (0.0.0.0), Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.
Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)
Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).

I want to do this to clean up the computer room wiring a bit and to run line drops to different rooms in the house where the internet will be utilized.Currently there are two PC's, a laptop, a tablet, sometimes a phone, and an XBOX using the internet. I want to get my printer back up and running on the network but thats another story. Only one PC is currently hardwired. I would like to run two cables into the room with the PC and XBOX that are currently using wireless, at least two into the computer room for the PC and network printer, and one or two into the living room for the blue ray player and possibly an internet tv.

I have setup a webserver on my home PC and I have forwarded port 80 on my router to the IP adress of the PC that is running the web server. The web server is working great; I can get to my web pages from outside of my home by going to http://MyIpAddress/Anyway, the problem is with the Windows Media Player plugin I'm using. I want to embed 6GB MPEG-2 videos into my web pages. I have some videos on my PC and I want to be able to watch them remotely by connecting into my web page. It works fine when I'm at home; other PCs can connect and play the videos no problem. The problem is when I'm at work. When I'm at work, I go to my web page (via my IP address in a web browser) and the Media Player plugin says "Connecting" for a minute, then it says Ready, but the video will not play. I tried using a smaller, AVI file (680 MB) instead to see if the problem was streaming such a large file, but the video still would not play.Do I need to foward more ports on my router so that Windows Media Player can connect back and get the information it needs?

View 6 Replies View RelatedMy Set up at home is as follows: [code] Now according to what I have read I should be able to set the subnet on .2.0 network to a subnet of 254 and this gives me 512 Hosts I believe however my question at this point is how to route between 192.168.1.0 and 192.168.2.0.Or when I set the subnet .254 does the router just route it automatically.I would still set the subnet mask on both networks to 254 correct? I believe I can only use 192.168.0.1 to 192.168.1.255 w/.254 subnet mask. However I already have some servers that are configured with applications (On the 192.168.2.0 network) that I do not want to change ips on because it would be a pain to reconfigure so, my other question is other than using .252 to extend it to 192.168.0.1 to 192.168.3.255, (I need the 192.168.2.0) is there anything I can do? Like use 192.168.1.0 with subnet mask of 255.255.254.0 to get the 192.168.2.0 network? The reason I asked is I was using a subnet calculator to try and figure this out but every time I put in 192.168.1.0 with .254 subnet mask it changed the ip to 192.168.0.1 to 192. 168. 1. 255.I would really like to use the netgear only. The way I have it now is not working I am able to ping the internet from the 192.168.1.0 network but I can't ping from 192.168.2.0 network to the 192.168.1.0 network.

View 2 Replies View RelatedAt the moment I have my home network (192.168.0.0/24) like as below (all connect using straight cables): [code] My Cisco lab equipment are in the basement all connecting to an access server which at the moment is plugged into Switch3-dumb (along with a printer & NAS).What I'm thinking is to replace the Switch3-dumb with a 3550 I'll be picking up later this week.Then using this to do as the Switch3-dumb did maybe by creating a native 'vlan 192' & putting it into a gig interface which will connect to the network using the straight cable, also putting the printer & NAS into the same vlan.This will hopefully still give me connectivity throughout.Then when required I'll like to use the 3550 with the rest of my Cisco equipment for setting up different labs (segmenting them from the home network by using different vlans etc.One of my reasons to implement the 3550 into the home network is to be able to play about on a regular basis (port monitor, traffic stats, etc).

I had a few of question about this:
Will the cisco lite version (rather than the more expensive cisco base software) support the 1000BASE-T SFP modules?
The 1000BASE-T SFP modules, are they auto-config? Have you the link for commands we can use, if required?
We don't have budget for stack modules, apart from that would you recommend we change anything with the new setup?
Does the X2-10GB-T copper transceiver is supported on the WS-X45-SUP6L supervisor?

My Wifi network has a wpa2 password that is a random string of characters and numbers and yet last month a rogue IP Address kept popping up on my DNS list. It has to be coming from my neighbor who's bedroom is about 15 feet away from my router. So unless someone is sitting out on my front lawn to do this then it must be him.I've been looking for software that will notify me when a connection my router is attempted and kudos if it also asks my permission first would be great.There are wifi packet sniffers out there like Cain&Abel, Airsnort, that sort of thing but I am not quite savvy enough nor do I want to turn this into a complicated hobby but just need a basic warningin case something gets past my passwords again
