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.

I have an indoor bike trainer called Computrainer.  Communication protocol is old-school serial port.  Eventually, SERIAL/USB became available and is still used today however with so many newer mobile apps, it would be ideal to have some way to communicate over Bluetooth, WiFi, or ANT+.  Prices for adapters vary a bunch.  Are these solutions all viable?

JavaScript Best Practices

I'm doing a wiring job with Cat7 cable (never done a job with Cat7 before).  The wiring to each room is already complete.  I now need to set up a patch panel, switch, and terminate some wall jacks.  I've been doing some research online and am having a tough time coming up with the best solution.

To my understanding, if I use a RJ45 connector I will lose the "Cat7 effect" and would be operating basically like a Cat6a.  Is that correct?

I've also read about different connector's that will maintain the "Cat7 effect" such as TERA and GG45.  

Is it worth terminating the wall jacks with GG45 or TERA, as well purchasing a corresponding patch panel and switch?  I would then have to convert from the TERA/GG45 wall jack to RJ45 anyway to actually hook up to a computer/network card.   How close are GG45/TERA connector's to going mainstream and being used in your average network card?

For the type of work being done, a drop in speed from Cat7 to Cat6a would not be noticed.  Would I be better off just terminating (and purchasing a patch panel and switch) with RJ45 and upgrading everything in the future?

I have a 2960X-48FPD-L switch in a small office and want to connect couple of AP’s (2802I) to it.
Is the PoE requirements sufficient of the switch and the regulatory domain must be Z. Is this correct
The office is in Brazil.

Cisco 2802 CWAP will not join 2802 Cisco ME Controller.

Pardon me I'm not Cisco expert but we've been running 2702E's in Autonomous mode successfully for a few years so obviously ME is a step up.

I have a 2802 online and I keep ending up with "Max retransmission count exceeded, going back to DISCOVER mode." when it tries to Join the controller.
This is first AP I'm trying to join and I don't have another one to test with right now. I need this one online so I can pull another offline and get it online.
Devices are on the same LAN and even switch for testing.

I changed the retransmit count and interval on the ME controller shown here:
(Cisco Controller) >show ap retransmit all

Global control packet retransmit interval: 5

Global control packet retransmit count: 8

AP Name             Retransmit Interval  Retransmit count
------------------  -------------------  -------------------
TX-2802-1                5                8


However this is what I end up with when the CWAP tries to join:

(Cisco Controller) >show ap retransmit all

Global control packet retransmit interval: 5

Global control packet retransmit count: 8

AP Name             Retransmit Interval  Retransmit count
------------------  -------------------  -------------------
MX-2802-1                5                8
AP00A3.8E90.F1DA         3 (default)      5 (WLC default),5 (AP default)
(The second one obviously being the one I want  to join)

Do patch panel ports need to have a corresponding port on the switch? So if you have 24 port patch panel you need a 24 port switch? Are there any devices that allow you to have virtual ports from a patch panel into a switch to reduce the number of cables needed?

Our network share is on an enterprise class NAS farm with flash and lots of physical drives. We can copy files to and from the network quickly, our performance with large Excel files and large Access databases is abysmal.

After raising the issue with IT, they gave us a test environment on a Windows Server share and it a bunch faster than the NAS drives, but IT considers this "just a test" and "temporary". The project manager in IT that is helping us doesn't seem to know why the Windows server share is so much faster, but I'd like to know why so I can advocate to make our network folders permanently reside on a Windows Server instead of a NAS.

Does anyone know why Windows Server is so much better? From testing I'd say that performing operations like indexing fields on 1mil record tables and such is about 8 times faster and does not suffer from the bottlenecks and freezes on Windows Server that we see on the NAS drive

Dear Guys
I need you to help me understand this problem, with this I-direct modem we are experience slowness on our link but when we do a ping test were are not experiencing drop packets or long latency. Know the internet provider is telling me that our TCP session are high and our modem have a limitation of 4000 sessions, can someone explain to me about TCP sessions

I am looking at switching from my physical old Cisco switches to a Meraki solution.  Anybody has any thoughts about Meraki, I'm planning to use their Firewall, switches and APs.

I currently am using Sophos for my firewall and the renewal cost for my subscription is a bit more than if I were to just outright purchase a Meraki hardware and subscription for 3 yrs.

Any major pros/cons?  The demo looked great for Meraki, but how does it work when it's actually in production and not just demo mode?

The other option is to purchase new Cisco physical switches, but those are more expensive than the Meraki solution.

Do not have experience with Juniper routers.

Have TeraTerm running on the laptop connected to a Juniper CPT2024 router on Com Port 2 which I understand to be the console port.

Ran every baud rate on the list. Still getting gibrish on the screen.

Once I get a command prompt, need to get in and clear the flash, and delete the configs, and prepare router for resale.

Hey Experts.  Looking to upgrade the Cisco software of several 2960x switches.  Current version is 15.0(2)ex4 and after downloading the newer version 15.2,4e6 but wasn't sure if I can go from where I am to the newer version without any steps in between.  Would appreciate advisement on this.  Thanks Experts.

NEC SL2100 phone system started behaving poorly a week ago Sunday.  Rebooted all network equipment, and nothing changed.  Reboot the phone system and everything worked for about 20 minutes.  Same cycle of events, about same time frame.  Next checked all network equipment for firmware upgrades.  Wireless bridge Engenius EnStationAC went from 2.x to 3.1.2.11 on both sides successfully.  Problem returned yet again, but now a delay in getting dial tone of about 3-10 seconds.  If phone hangs up and connects immediately, no delay happens.  A monitoring computer is the only non-phone device on the entire voice network.  It shows random packet loss to phones.  The phone problem was originally they begain restarting at random.  They are not all happening at one time.  The delay never happens to VOIP phone on the system side of wireless bridge.  Engenius has yet to comment on the issue.  One phone (Only one phone) peforms IGMP actions accoring to Wire Shark.  Removing that specific phone solved the problem for almost 2 hours.  Yet it eventually returned.  All the time I have brought another laptop in for testing and moving it to both sides of the bridge.  If I am on the system side, I perform ping tests to the phones on the far side of bridge.  If I am testing the phone system resources, I am on the opposite side of bridge.  I perform around 1,500 packets to 3 devices simultaneously each time I test.  No latency or packet loss ever.  I have introduced a new PoE switch on the system …

Hi,

I may have a stupid question but, I have ip address for proxies and I want to find open ports for it. Can you help me find online tools for this?

Thank you!

I want to buy a 1M FlexStack Cable for my 2960s switches, but I can’t see the part number (CAB-STK-E-1M) for price estimation in CCW.
Any advice why

I have a data jack that is terminated; but, not properly labelled.  I am trying to use a tone generator to find the correct patch panel connection that I need to use and cross connect the ethernet correctly to the end point.

https://www.youtube.com/watch?v=JHRIiw3OR6Y

The problem is that this specific data jack is in a machine shop floor and when I activate the toner every patch panel connection is triggered in the room.  If I turn off the toner generator every patch panel is still sounding off in that room.

If I try the toner generator in different locations(other rooms) there is no problem.  The toner generator works as I expect it to.

What could be causing the toner tester to sound off in that 1 specific patch panel?  Could it be that the ethernet cables were not grounded correctly?

Need to block network users from being able to access BitTorrent (BMTORRENT).   I have a Sonicwall TZ-215 along with the premium content filtering.  I can block the URL of the usage, but can not determined the proper ports to target the service to block.  

Goal is to not have to upgrade to the "Application Control" that can detect the signature of the traffic or such.  I am fine with blocking the defaults or making more difficult for the person.  I understand that they could use other methods to avoid detection.

Interface Multilink Vs Interface Virtual Template on Cisco Routers

I would like to know the difference between using the commands :
Interface Multilink Vs Interface Virtual Template

it looks like they achieve the same thing.

Any idea ?

Have a client where the building power isn't that stable. Done everything we can to have maintenance clean up the power issue. Meanwhile two UPS went out at the same time which to me means a surge happened. Simple question, what do ya'll recommend for a medium business running a PowerEdge Server, 2012 Server Storage, three switches, phone system, and two workstations. This is the server room and not the entire business - FYI.

I need to provide a summary if there is any risk in the following 'practice'. We have a number of users who leave there desktop PC's running overnight in an office environment. They are always locked, but seem to be too lazy to actually shut the device down for some reason. The high level of management are aware of this but seem of the opinion 'so what'. I am not sure there any real obvious security issues so long as its been locked, except perhaps disclosing the officers logon name., I'm hoping there are some other issues which have perhaps been overlooked that can build our case to issue disciplinary action against staff for doing this kind of sloppy behavior.

We have 2 x Aruba 7030 hardware appliance controllers that we want to use as local controllers for our Aruba Wireless system.  Another administrator setup:

2 x Virtual Master Controllers.
2 x hardware 7030 controllers.
1 x specific VLan IP Subnet where there Hardware local controllers reside on with the Wireless Access Points.

Both Aruba hardware appliances are in 'Standalone' mode. We wish to change the mode from 'standalone' to 'local'.

My question is how can I change the mode of the hardware controllers from 'Standalone' mode to 'Local' mode?  I hope I do not need to reset the controllers to factory default settings.  

I have found a web site ( https://community.arubanetworks.com/t5/Wireless-Access/change-controller-role-from-standalone-to-local/td-p/279521 ) that states

"... You should only have to add it as a local controller to the master via cli
 
>masterip <ipaddr> ipsec <key>  ..."

Since, I have never done this before I just want to make sure that I understand what needs to be done.  Hopefully, I can communicate with someone that has actually done this before.    My understanding from the above web site is:

1.  You can change the mode of a controller without re-setting it to factory default settings.

2.  Login to the hardware local controller and from the C.L.I. >masterip <IPaddress> ipsec <preshared key><enter>

3.   The IP address that must be entered is of the Master Mobility controller; but, what if you have 2 master mobility …
