Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Internet through Cable line or Satellite

I have read online that there are fiber cables ran through the Oceans to reach other continents in order to provide internet connection.
I have also read that internet connection is provided through Satellites somewhere in the Orbit, and there is no need to run cables from one end of the globe to another.

I am not sure which approach is used to have people in the world connect to Internet.

Any Expert to shade some lights on this ?

Thanks

A few years back I had SolarWinds Real-Time NetFlow Analyzer working with my Cisco 3750x switch. Recently we had some suspicious traffic so I installed a new version of the software on a Win 10 machine. I can connect through the software to my switch, I can see all of the interfaces but none of them show NetFlow enabled. When I click on the interface I want to monitor then click "Start Flow Capture" I get a 'NetFlow is not detected on the selected interface'.

How do I get this port configured correctly to capture NetFlow data?

Additional Facts:
IOS version 15.0(2)SE6

Config on switch:
int gig <port to be monitored>
ip flow ingress
ip flow egress

ip flow-export source <port to be monitored>
ip flow-export version 5
ip flow-export destination <IP of my Win 10 machine> 2055

Open in new window


Per this thread- https://thwack.solarwinds.com/thread/20498 
I tried to run the ip nbar protocol-discovery and the ip route-cache flow on the port to be monitored. Neither of those commands were accepted on that port.

Any help is appreciated.

EDIT:
I've had users on other forums attempt to help me by pointing me to towards flexible netflow configurations that use the command ip flow monitor <name of monitor> input applied to the interface they want to monitor. My switch does not allow flexible netflow to be applied to non-service module ports. What I'm trying to monitor are the standard gigabit interfaces.

The netflow commands I can apply to those standard interfaces are those listed above: ip flow ingress and ip flow egress. How do I get netflow analysis that way?

Hello People,

This is kinda engineering question. Its about the hardware and power knowledge.

I have a Ubiquiti Loco M5 which is connected to a public access point (No encryption required)
Everything is working, except random disconnection which I'm pretty sure its because of the range. Its connected with -80
I am 1 Km away from the AP - but the signal is poor because Loco doesnt have enough power!!

How can I boost the receiving on Loco M5. I mean HARDWARE. not configuration within the Loco which I tried EVERYTHING.

I need something to add to the device in order to make it more powerful for receiving signal! like changing the adaptor? or PoE? I've heard if I changed the power supply, it'll help. But I have no idea about the power and what should I buy.

Any ideas?

Thanks

I hope I can get some inputs from you on network design.
This electronics manufacturing company will be building a 2 storey, 100K square foot facility.
The mail floor - all the manufacturing machines, computers and servers running manufacturing software
The 2nd floor - the main server (Microsoft SBS), SharePoint Server, LOB software servers, and computers used by office staff and engineers.  

They have less than 200 employees, over 120 computers, 5 physical servers, some VoIP phones. They are all on the same network. Currently, there are only 28 IP free addresses available from the DHCP server (Microsoft SBS)

Here are my thoughts about the network in the new building
1. Install stackable switches in each floor's server room. Connect the two groups of switches via a long high speed trunk cable running thru the floor.
I think this will keep the network traffic on the main floor in the main floor network from the 2nd floor network, which optimize the bandwidth.
Currently, they are using D-Link DGS-1510-52 switches, which have been quite reliable, except that i had to power cycle one of them twice in the past years, and their firmware are a bit buggy.

Is it worth to deploy Cisco switches which are more expensive and cause a learning curve? Is there such a long high speed trunk cable at all?

2. Separate computer network, VoIP phone network and Security/Access Control network with 3 different networks.
This will release quite some IP addresses from the DHCP …

I have an old Dell PowerEdge 2800 domain controller sitting in my office that is collecting dust.  I was thinking about converting it into a server that we can use to backup the hard drives of the individual workstations in my office.  It has a boatload of hard drive space in a hardware RAID array, which I believe is large enough to hold the workstations.  There are 9 workstations that would need to attach to the server.  Right now, it has MS Server 2003 installed on it, but not much else.   Our workstations are a mix of Windows 7, Windows 10, and I think we have one Windows 8 laptop.  On a suggestion from a guy who does some IT for us now and then, I was thinking about reformatting the server with Linux to do this job, but I don't know if that is the best way to go about it because I haven't used Linux since college.  

My question is this:  Is there a software solution available that will allow us to automatically backup our workstations to an old server that is relatively simple to install and maintain?  We have a small business and don't have dedicated IT staff, so I will probably have to do this myself and I don't want to have to learn something really complicated.
 
 We don't need the domain server anymore and I am willing to install a different operating system if necessary.  Thanks for any suggestions.  If the suggestion is to go with another operating system, please let me know the build or the version.  Thanks.

We have one client purchase 2 MX64 and 1 X MS250 For the beginning i design to create the vlan2,3,4 in MX and also DHCP.

My thinking is we have the 2 unit MX64 so i can configure as warm spare.if one unit MX is down so another MX will be can active and all the function will not impact to user.

But recently we receive msg from customer IT team .They would like configure VLANs in MS250 and throw the default route to MX .

May i know what are the benefit to configure DHCP and inter-vlan in switch and please advice which method is better

We are using Cisco Prime 3.3 in our infrastructure. We're trying to use the discovery feature to seek out devices and populate Prime's device inventory. The problem that we are having is that when the discovery job finishes there are a number of devices with the same error "ping reachable. Got snmp timeout when querying system table from the device". We've verified the SNMPv3 credential before trying the job, however we are still unable to get it to work. We have been stuck adding devices manually at this point. Has anyone experienced this problem or similar problem before? Is there something we should check or change in the discovery settings? Thanks!

Can a POE injector be plugged into any port on a (POE enabled) Switch?

This is the POE injector btw

I have a network with a DrayTek router connecting it to the Internet.

My ISP tells me that I am sending up to 600Mb / hour up to the Intenet at times. I do not use cloud backup or storage. I am concerned that one of my PCs may have been compromised, causing this.

I have installed SmartMonitor from DrayTek, and set the router up to do port mirroring as per their instructions, mirroring all LAN ports and the WAN side too.

Looking at the SmartMonitor report, I can only see reports on downloaded data, so this isn't helping me to diagnose the large amount of uploads.

Can anyone suggest a better way to monitor this?

Thanks,

Richard

Hi,

We have a Denon AVR X4300 which is connected with speakers and we have surround sound for music, radio, etc.
https://www.denon.co.uk/uk/product/homecinema/avreceiver/avrx4300hv2

Back of Denon:
https://www.google.ie/search?dcr=0&biw=1125&bih=663&tbm=isch&sa=1&ei=i-2oWtG2K8iHgQaApqjYAg&q=denon+avr+x4300&oq=denon+avr+x4300&gs_l=psy-ab.3..0l2j0i24k1l8.629949.634464.0.634927.23.15.0.0.0.0.471.1897.2-1j2j2.5.0....0...1c.1.64.psy-ab..18.5.1896...0i67k1.0.WNcM6UitMAU#imgrc=JSOEvsQMsE7U3M:

We are having problems connecting FM internet radio stations to our Denon AVR X4300.

At most, 3 radio stations connect with use of internal FM radio antenna connected to Denon AVR X4300.

A different radio in the room, which is a basic radio with antenna, has over 10 radio stations it can connect to.

1. Which provides the best quality radio over the surround sound system; Internet radio or external FM Antenna?

2. If external FM Antenna is best quality for radio, what would be the best external/ outdoor FM DAB radio antenna to use for Denon AVR X4300?

3. No point in buying and installing an external antenna and then finding out the the sound quality is better on one of the internet services.
It would be redundant and annoying to finding that out later.

Thanks,
Robbie

Extending the length of fibre. The network supply is Single mode up to my ONT. I wish to mov the ONT from an outhouse into the main house, I have 150m length of multimode fibre already in position between buildings. I have fusion spliced my SM network feed to my MM fibre, fusion spliced a new connector on to the MM and have only increase my budget by -3dB. The optical power result is still well within the ONT spec and the ONT has stood up and given service! Can I expect any other issues, now or later?

Dear All,

We have installed Huawei  IPC6225-VRZ-SP Bullet IP Cameras on different location for surveillance. We are in strange situation that three cameras have been burned one by one installed on CISCO POE Switch 2960 X. All other cameras are also installed on different CISCO 2960 switches and working fine. Can any one please help to rectify the issue. This is due to high voltage generating by 2960 Switch or may be any other reason.

Building an Effective Phishing Protection Program

Join Director of Product Management Todd OBoyle on April 26th as he covers the key elements of a phishing protection program. Whether you’re an old hat at phishing education or considering starting a program -- we'll discuss critical components that should be in any program.

I have an old home router that I've been using for awhile with DDWRT on it.  I've purchased a Sonicwall TZ300 that I'd like to use as the main gateway.  I have that working fine but now I'd like to add wireless back in via the DDWRT.  

I've disabled DHCP on the ddwrt and set it to router mode.  I've given it the IP of 192.168.168.169.  The Sonicwall is 192.168.18.168.  I've connected together via a LAN port from the WRT to a an interface on the Sonicwall.  

I'm confused as to what/how exactly I should be setting the interface the WRT is plugging into on the Sonicwall.  I've tried a few different things without luck.

Have the following:

Edgemax with Subnet of 10.0.10.0
USG with subnet of 10.0.1.0
I am trying to create a site to site VPN, but I am not very familiar with Ubiquiti hardware.

Followed the WIllie Howe video online, and I'm sure the addresses are correct, and I also checked the Ubiquiti KB page, and as far as I can tell, I have the correct settings, but no tunnel is made.

See the attached pics for set up.  

For the Edgemax, the local ip is what the external internet address is.  And the Peer is set to the USG external Internet address.
For the USG, the Peer and local WAN IP are reversed from what the Edgemax is set to.

I have also included the Edgemax firewall rules that I have added, but I have not made any rules on the USG yet as I am not sure what to add.

Any help is greatly appreciated.

No matter what router I use, I only get 30 - 50% of the internet speed through it.

If I connect a laptop directly to the Comcast modem, which is in "Bridge mode" so that the connected device gets a public IP address via DHCP, I get about 100mbps.  If I connect a router BETWEEN the modem and the laptop, the speed falls to 30-50.  There is NO OTHER device connected to the router or the modem.  I have confirmed this problem using a SonicWall TZ400, a Cisco RV180, an ASUS RT-N12, and a UTT ER518.  The issue remains for each of those routers.  I also used the same patch cables for each measurement.  Wireless is not involved.  

Why does this happen and how do I change it?

I just purchased a Siemon 10g ip 24 port patch panel and mounted it in my house for a home lab. I punched down my first port last night but something strange is happening. Right now I just have the cable coming directly from a laptop NIC to a punched down port on the Siemon 10g ip. The CAT 6E cable I made myself using the T-568B configuration. While this is my first patch panel punchdown, I have created a lot of cables in the past, using this same exact roll of 6E, so I am fairly sure my wiring is correct. I then have another cable going from the patch panel port to my Cisco SG300 switch. Now the problem is that I have no light on the SG300 switch port. I have 20 other devices working fine on the switch. I thought I wired it wrong but I re-wired the cable 3 times. The strange thing is that the laptop has full connectivity with lights on the laptop NIC. When I plug a cable into the laptop and plug directly into the switch I get lights on the switch port. I have tried multiple cables and multiple ports with the same result. When I unplug the cable coming out of the switch that is coming from the patch panel and insert it into a cable tester I don't get any lights on the cable tester check. Nothing whatsoever. without the patch panel the cable tester works fine. What could be wrong? Why do I have connectivity just no light on the switch? Why is the cable tester not showing me the wire checks? I have asked several network people and they have no idea. Did I purchase the wrong …

I recently purchased an Ubiquiti EdgeRouterX for home use. I would like to have my cable modem (192.168.0.1) plug into Eth0/POE in. I would like Eth1 to plug into my existing router (10.0.0.1) for normal filtered family access and WiFi. Eth2 would be used for a direct link to my SOHO office computer running Win 10 and defender. The Eth4/POE out would go to a POE wireless (Ubiquiti) device for business WiFi computer access and cell phone access, How would I segment these ports so they are not on the same network yet receive the signal from the source cable modem?
