Span LAN 660 Feet Between Buildings?
Oct 15, 2012
Two buildings on same farm property 660 feet apart. Cable internet to one building does not reach 660 feet to second building and the cable company will not put it in. Wireless between the buildings is not out of the question; but, I've never done anything this distance before and I am concerned that signal loss over 660 feet might degrade throughput.
So, what is a feasible way of getting the signal from the first building 660 feet to the second building?

I need to a run an Ethernet network between 2 buildings 1000ft apart. The buildings are in a forest so I don't think wireless is possible. What kind of cable can I run between the two buildings and what type of adapters do I need on each side?

I am having some problems creating a SPAN port on my Cisco 871 (running IOS 12.4-11T). My 871 is connected to a DSL modem, and uses "IP Negotiated" to get its dynamic ip address.I want to monitor the WAN port (FastEthernet4) using SPAN, but when I type "monitor session 1 source interface FastEthernet4" into the cli, it is rejected. I can successfully use any of the other FastEthernet ports, as well as Vlan1 as a source for the SPAN session. I have tried to use Dialer0 instead of FastEthernet4, but it still doesnt work.

the camera is about 30 feet from the router. Is it too far for the camera to be detected? After I mounted the camera at the front door, after connecting the camera to the electric power, I saw clearly the picture. But after I finished mounting, I could not see the picture anymore. On the computer, it was stated that the camera was offline.

I have a Linksys WRT54G 2.4ghz at one point and need the signal to go 300 feet to another location. Running an RJ45 cable that distance want work and no way to run any kind of land lines. Everything will have to be done wirelessly.
What equipment do I need to get the signal to reach out to 300 feet?

I need to bridge from our office to our shop that is around 800 feet away. Here are the Details
I need the 2.4 ghz antenna for client access (Iphones are not compatiable with 802.11a) The locations are 800 feet away but are line of sight. I need to use the 5ghz antenna for the bridge i have 2 aironet 1242ag's I have 2 2.4 ghz AIR-ANT3213 antennas (planned for client access) I have 2 2.4 ghz AIR-ANT2506 (maybe useless for this)
My problem is that the range of all the listed 5 ghz antennas. None that i can find will bridge 54mb over the 5ghz radio for greater than 170ft
The closest that i can find is AIR-ANT5195. If i put these on both sides and it is outdoors line of sight, will the best i can hope for is functioning and 6mb
Are there options on 5ghz that i am missing.

I've recently lost my ability to access the internet at uni and as this is quite an inconvenience I am considering some alternatives, the most viable one I've managed to come up with hinges on the fact that I live in a building which is only a road and another building away from the main uni buildings (3 buildings on 2 city blocks), basically it looks like this: UNI BUILDING 1 | UNI BUILDING 2 |ROAD| UNI BUILDING 3 |ROAD| MY APARTMENT.So I'm thinking of building one of these: url.. or waiting for the r20000g (dual band) to come out and buying that.THEN the area I'm having a bit of trouble with: I need to get reception about 600-700m away through buildings, so I've been looking at Yagi antennas and such but can't seem to find any information on the following:
1. Will a high powered directional antenna go through a few buildings and still make it 1km (.6 miles)
2. How directional is a directional antenna? like if I point one in the general direction of the building how accurate do I have to be? (I have no problem buying 4-5 antennas if I need to)
3. Do I need a new Wi-Fi antenna for my laptops? it seems odd to me that a laptop would be able to transmit back 1km while I need a giant antenna to get to the laptop (I know its not this simple but it still seems odd)

I'm a skydiver and since 2 years, the dropzone where I jump have been putting webcam around the area to see what's happening on the dropzone live online. I talk to them about a project and they said it would be great but I don't know how to do it or if it's even possible to do.We would like to put a wireless camera onboard one of the planes so that ppl can see what is happening up there and that would stream live directly on their website like the other cameras they have around... the thing is, we jump from 13 500 feet.

I've been in a home office for the past 2 years with 30mb internet, but I will be getting an office soon downtown. The building I'm moving into has free wifi, what is my best option to connect to this with my desktop?
1. Using an ethernet cable from my desktop to my ASUS rt-56n router as a bridge to connect to the buildings wifi.
2. Buying a wireless adapter to connect to the buildings wifi.
My phone only gets 2 bars when connecting so I'd like to know which of the options above will give me a faster and more reliable connection.

I have two buildings on my property that I need to network together. One is my home about 3500 Sq. Ft. and the other is a garage about 3000 Sq. Ft. The two buildings are about 250 feet away from each other. Both are fed from the same utility pole that is half way between them. That means both are on the same transformer, but each has its own metered electrical service.Right now I am using 10 Mb. Home Phone Line network adapters. They work OK but data speeds are limited to about 5 Mb. of throughput and the adapters are no longer available. I also have WiFi at both locations but neither one will talk far enough to cover the other building.I also use X10 remote controls in my house. I have tested them from the house to the garage and they do not work at all over that distance

I have 2 of these in a Bridge between 2 buildings. Cisco support replaced them with 2 BRAND NEW units after 6 weeks of waiting, that do the same thing. Spent so many hours on these turds it is insane. the thing goes down with the wind, tinker with it and maybe you will be up for a few hours or days then back to down again. Thinking it has something to do with the firmware or a power saving thing. Works great when it is up though. I am still trying stuff to get it to work stable. To much money invested in them now to start from scratch but they wanted budget equipment in place and not Cisco Aironet.

I currently have WLC 5508 and a few campuses with LAP 1142, each with 2-3 vlan. Now one of our campuses have a building thas is a bit far away and needs network (wired). We can't get fiber or TP-cable there in a good way. So the plan is to get two 1262 or 3500 with AIR-ANT5160NP-R antennas and get a wireless link working between the campus and the building. And then connect one of the AP's to a switch in the other building to provide it with wired network.
The problem is that I can't find information on how to do it. Should both APs be in autonomus mode? I probably only need to have 1 VLAN in the other building but I am not sure yet. Is there a problem with transfering several VLAN over the WLAN-link?

I have 2 - 1410 bridges ( point to point) between two buildings approx 600' apart. They seem to be aligned well ( Signal -52dBm, SNR 41 ) and have been very reliable. However, I cannot seem to run more than 26Mbps thru them.is there any recommended tweaking that can increase my throughput ?

I got Fios installed this week. Router is the Actiontec MI424, it sits int he living room. I ran a speed test of the wifi on my laptop in the living room, and the internet speeds were great. Here's my problem. I'm in a 2 br condo, not a huge place maybe like 1200 Sq feet, same floor. Wifi is awesome in the living room, but in the bedroom it hangs. I still have a signal, varying for low to good, but it takes forever to open a web page, to the point where you can't use the internet. Bedroom is just down the hall.I called Verizon. They told me they can only guarantee the wifi signal 10 feet from the router, after that no promises. My frustration is that with my previous provider, which was giving me a slower internet connection, my wifi in the bedroom was fine and the router was in the exact same spot. Of course I used my own router? I know there are instructions on connecting my old router to the fios one and using my old router for wifi.

I am having a problem in connecting two Cisco 2960 Switches between two different buildings using Cisco WLC 2504 & 3 Wireless 1552S APs.
- One AP is directly connected to Switch - 1 where WLC is connected and serving as a RAP
- Another one is working as Mesh in the field.
- Third one is a Mesh Access Point wired to another Switch - 2. (Bridging is enabled)
All the APs, WLC & switches are in the same network 10.3.x.x subnet mask : 255.255.240.0?WLC is working with default management interface whereas switches are having VLAN1 configured as default VLAN.All the port for the switches are Trunk ports?Once i am trying to ping the RAP or any MAP from Switch - 1 I am sucessful but once i am pinging Switch - 2, its not replying. Similar is that case from Switch - 2 side.

I was successful in configuring a new e1200 in bridge mode to extend my network. I did this with the routers side by side. In then moved the e1200 to a new location 150 feet away and it will not work. I previously had this working with an older linksys router. It will not deliver a Internet connection.

Im trying to span a trunk port and capture the dot1q headers on the destination. I'm positive I have it configured right (encap replicate) but wireshark just isn't seeing them. Im trying to capture them on a seperate NIC on my Windows 7 64bit pro box. The NIC is a realtek RTL8169 and it just won't capture the headers. I've also tried the built-in motherboard NIC (which is also a realtek) with the same results.

I am hoping you can provide me with some opinions, feedback, thoughts on the following. We have some Cisco 6509 switches in our environment currently hitting around 60% usage on the Router overall statistics.
Now we are looking at implementing an intrusion detection system but by being as least invasive as possible to the network. Our thoughts are to utilize a SPAN port on the switches to send traffic to the NIDS device but we have concerns of the following. The limitations of SPAN sessions on 6509's . The overhead on the switch of turning a SPAN session on and leaving it on permanently.

I am trying to configure RSPAN for one of my client. They have Server-Client VTP architecture. Voice Recording Server is connected to C4507. Agents are connected to C2960 and C3750. I got 2 sessions configured and the connectivity is a as follows:
1. Voice Recording Server-----C4507-----C2960-----C2960-----Agent IP Phones (Session 1)
2. Voice Recording Server-----C4507-----C3750-----Agent IP Phones (Session 2)
Recording works with Session-2 but not with Session-1. I understand the problem could be due to multiple reasons: 1.1. C2960 is working in client VTP mode so i cannot add remote span command under the vlan configuration. 1.2. C2960 has LANLITE IOS image which i am not sure if it supports Remote Span.

I have CISCO catalyst with VLANs (VLAN ID 33, 36, 40-53) configured. I need to configure port mirroring in Switch 3750 for NAC (Network Access Control). I need to Monitor all the VLANs. Here is the SPAN configuration of switch: [code] Monitor session 1 source vlan 33 , 36 , 40 – 53.Monitor Session 1 destination interface fa 1/0/8 (here I am not able to set encapsulation dot1q ) because the error occurred saying %one or more dest port do not support the encapsulation%.

I currently have IOS image cat4500e-entservices-mz.122-53.SG5.bin. According to my research it appears SPAN is supported on this OS. However, after looking at procedure notes using websites like here:
[url]... I cannot find and obviously not figure out how to use the SPAN command. My main objective is to simply setup a port mirror on one of my TenGigabitEthnet interfaces and from what I read SPAN is the best way to setup a tap interface on a cisco switch.

Been dealing with a strange problem for several days now. It started out with a problem that I thought was VTP related but ended up being something else. I setup a span port on a 3750 that I am connected to that was mirroring the trunk connection coming into the switch.
Never saw an VTP traffic come across the connection but doing a sh vtp status indicated the traffic was arriving and getting processed. When I found some debug commands (debug sw-lan vtp), I was also able to see the packets go between switches. Seeing this issue concerns me that there is other traffic that isnt showing up during a span session.
I know that doing a span on a switch, especially using a trunk port as a source, isnt a good idea. Since I didnt have a TAP at time, this was my only choice. I have since borrowed a NetOptics TP-CU3 tap from a good friend and was able to confirm the VTP traffic was going across the trunk connection between switches.
All of my 3750's are running 12.2.55.SE.

I have a Cisco 881 router running 15.1(4)M4. I am trying to configure SPAN on it to mirror my outside interface (source) to one of my LAN interfaces (dest).
!--- WAN interface
interface FastEthernet4
description Comcast WAN$ETH-WAN$
[Code]......
As you can see from the above output there is a problem with the command on this interface. When I try to set Fa0 as my source it works fine:
rtr(config)#mon session 1 source int fastEthernet 0
rtr(config)#
Is this because fa4 is layer 3 and fa0 is a switchport? If so, is there another way to set fa4 as the source?
