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 Cisco ASA 5516X Firewall, the serial number of the chassis is different than the one extracted from the "show version" command.
Does anyone know which one to use for creating and assigning to a smartnet account?

HTML5 and CSS3 Fundamentals

Build a website from the ground up by first learning the fundamentals of HTML5 and CSS3, the two popular programming languages used to present content online. HTML deals with fonts, colors, graphics, and hyperlinks, while CSS describes how HTML elements are to be displayed.

I am looking to upgrade my router to a router that can handle a higher volume and faster, but the number is confusing me a little.

I currently have a Ubiquiti ER-X and looking at the ERPoe‑5, I compared all the specs [RAM, Storage size, 1518 byte packets] and the ERPoe‑5 is higher or same, except for 64 bytes packets which the EX-R the throughput and pps, same is with the CPU frequency on theses 2 the EX-R is higher [EX-R throughput 957 Mbps pps 1,400,000 and the ERPoe‑5 throughput 490 Mbps pps 730,000, CPU frequency ER-X 880 MHz ERPoe‑5 500 MHz both CPU core count 2]

Please help.

I need to separate a bunch of stuff into VLAN's for my ubiquiti based network which I am aware of how to do. But just need to know if the correct way of doing this is to put all networking hardware on its on VLAN.

I only have Ubiquiti gear and they are a USG, Unifi Switches and AP's

I have a Netgear Nighthawk Router and I am trying to block a specific port, 42443.  The issue is the port still shows open after I blocked it at the router.

  1. Clicked on Advanced tab
  2. Then Security tab -> Blocked Services
  3. Used below settings and rebooted router:
    • Protocol: TCP/UDP
    • Starting Port:      42443
    • Ending Port:      42443

The port is still open. I can go to https://xxx:xxx:x:xxx:42443 and get to a page, 404 not found. When I surf to http the browser reports ERR_EMPTY_RESPONSE.  When I go to http://www.canyouseeme.org/ and add my ip and the port, it shows it is open.

I have a comcast router that is in bridge mode that connects to a Netgear Nighthawk r7000 router where I added the block. There is a Cisco SG 300-28P 28-Port Gigabit PoE Managed Switch attached to the router but from what I can see, it is basically being used as an unmanaged switch. Attached to the switch are VOIP phones, ubiquiti AP's, computers and multi function devices.  

How can I detect what on the network is using port 42443?  Am I missing something in trying to block that port on the router?

First Question.

Ages ago I had two switches given to me: a Cisco 2950 and a 3Com SuperStack 3 3C16592B.  And they've been sitting tossed aside for a long time.  I'm now in the process of decluttering and one has to go.  Which one and why?

Second Question

Now I'm a total noobie when it comes to these switches.  If I remove all passwords and take these machines back to factory or default they can be used as dumb switches, that is, I can plug anything into them and they'll function perfectly normally, getting their IP addresses from my home router?  I've just started playing with the Cisco and examining how it has been configured (shudder VLANs everywhere etc etc etc) so I'd like something simple to start off with before I venture into unknown areas.

Should I worry about humidity in server room?
The server room is in the design stage. It may have 2 open racks and 3 cabinets which mount servers, UPS, etc.  
The temperature will be well controlled by A/C system, which does not offer humidity control. Is this a big deal? I usually don't pay much attention to humidity in the past.

Hello, I got Cisco SF-220 48ports = 2 in the same rack, the first SF-220 48 ports connect to the second 48 ports via GE1 port.
the second 48 ports connect to another remote location via SFP MGBSX1 for both 2 ports.

my question is can the SF-220 48 ports GE1 and GE2 can use at the same time with both SFP MGBSX1?
since my current situation the SFP won't work if the GE1 or GE2 are in used.

thanks

CAT6A or CAT6?

The client is building a 100K square feet new manufacturing facility that potentially may have 500+ network cable runs - data, voice, WiFi APs, security cameras, etc. This new facility will be ready to occupy in less than a year.
The cost of deploying CAT6A can be 2.5x or 3x more expensive than CAT6, which is about $20K~30K more.
Does the cost justify the future proof of 10GB?
If you were me, will you propose CAT6A or CAT6? And importantly, the reasoning to convince the client?

Thanks!

PS - all the network devices (Servers, PCs, network switches, etc) that will be moved to the new facility will be 1GB

Is there software that tests noise on CAT5e and CAT6  cabling? I hired a company to test the cables and they said everything is above 1G and for the most part I believe them as I witnessed them test drops and make repairs on several damaged jacks. My concern is they didn't include a report with their invoice. Extremely disappointed as I mentioned the report was imperative for us to decide if VOIP is an option for my client.

I've insisted they put a report together and I'm aware the Fluke they used provides the one needed. While waiting on the report, and my suspicion is they forgot to turn reporting on, is there any software available that can give an indication of noise or how well VOIP will work on my clients network. Everything tested above 1G but there are still concerns I would like to eliminate. One being noise.

I've tried Solorwinds and wasn't impressed. Any other options available?

We have a device that we cannot connect to our network.  

This device was connected to a Linksys hub through a patch panel to Device#1.  It has a 192.168.3.0/24 assignment on this specific device#1.  


For testing purposes we tried using an ethernet switch to connect Device #1 to the network and we discovered that when we connect Device#1 to a switch ethernet port and amber light comes up for that switch port connection.  If we connect a different device (Device#2) to that same switch port we have a green light and communication works.  Hence, the connection from the switch port to the patch panel and then to the end device is a good connection.

It was suggested that either:

- Duplex-mismatch (perhaps Device#1 is forced to full duplex) since it was originally setup to connect through a hub and that did not work.
- Something else is wrong with Device#1

Since we do not have administrative access to this specific switch or to Device#1, it was suggested that we use a crossover cable to connect the devices from the switch or the Hub to Device#1 to see if that will all network communication.

Can someone explain to me how a cross-over cable may fix a duplex mismatch problem?  I have only used a cross-over cable to connect 2 PC's together; but, I have limited experience with crossover cables.

This is 100k sqaure feet, two storey, new manufacturing facility, on its stage of network/architect design.
We estimate that there will be 200 spots that need network access, for computers, VoIP phones, WiFi APs, smart TVs and security cameras.
In about 80 spots of the above, a VoIP phone and a PC will coexist.  These spots are the sitting spots or cubicles for engineers, managers and office staff.

The main question - should we run two network drops or one network drop in each of above 80 spots?
Option1: Two drops - One for VoIP phone, the other one for the computer.
Option2: One drop - VoIP phone and the computer will be daisy chained.

Not trying to over complicate the above main topic, we do have a few other questions as below in case you'd like to share some insights as well
1. Should we separate VoIP phones and computers into different VLANs? Why?
2. If we put VoIP phones on a separate VLAN, will the above Option2 still be doable?
3. Should we deploy CAT6A or CAT6 cables? 10G network is getting popular.
4. Should we run all cables directly from the end spots to the server room? Or, install some switches in the middle?
5. Any other thoughts? Or anything we should be aware of?

Thanks in advance!

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?

What power outage TRACKING systems do you recommend that would do what my
https://www.lacrossetechnology.com/temperature-and-humidity-monitor-and-alert-system-with-dry-temperature-probe/
currently does, but every 1 minutes instead of every 15 minutes ?

My UPS is plugged into a natural gas "always on" generator, therefore the UPS would show a 5 hour
power outage only lasting about 30 seconds, just enough time for it to switch over to natural gas

Our business just got a new copier.  The old copier drivers work on the new copier, but I want to update workstations to the new driver.  So, I added a 2nd printer GPO (users/policy/windows/deploy printer) and (computers/policy/windows/deploy printer), so the transition would be seemless to the end user.  In a couple weeks, I want to remove the old printer driver gpo (gpo setup the same way).  If I simply delete the old gpo, will the printers disappear from the users device & printers?  If not, what do I have to do to remove the old printer install?

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?

We need a fax line (RJ11) to plug into our e-STUDIO3005AC. Verizon came out and ran a cat5e cable to the printer from the verizon ONT and gave it a telephone number. Issue is we need an RJ11 to plug into the copier. Should I buy this https://www.amazon.com/gp/product/B01N8XIT4O/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Its basically an RJ 45 - RJ11 cord. Would that work if I plug the rj45 into the cat5e wall plate and then the rj11 into the fax? Or do I need to do something else?

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.
