Brocade FWS648G-POE

I have an older Brocade switch I would like to just use for POE. I have the Brocade FWS648G-POE FastIron 48 Port Ethernet Switch - 7.4.00 L3 image.

Most of the information on line is for newer switches and my switch doesn't see to follow the same CLI syntax.

I need help and advise with setting this up and configuring this for a very basic setup.

LAN disconnects automatically

I have a mac book pro that since Thursday, all of a sudden, it disconnects from the LAN. The wifi works fine.
I replaced the network cable and the 5 port switch that it was plugged into. I have also tried a different computer with the same cable, and
it didn't disconnect with a different computer. Since a different computer works fine with the same network cable, I'm thinking there's an issue with the MAC.

I don't use MACs much, so suggestions I can try to isolate the issue?

I'm currently using DHCP with windows servers. I have about another 9 or 10 MACs on the network, and no one else reported any issues just yet.

Thanks. D

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.

Network cable run in new building - two drops vs one drop

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!

Vlan db not updated

I have 3 switches. I have 1 vtp mode server (A) and 2 transparent (B & C). I changed the B & C from transparent to client. I added another vlan on A. But only B updated its vlan database. I am not sure why C did not. A is directly connected to B via copper. B is connected to C via fiber.

We have a Cisco Catalys 2960. We are short in ports in one office, we need to connect a UniFI 8 Port switch to the port, the port shuts down on the switch in err-disable state, due to bpduguard. so I figured I need to disable BPDU guard feature on that port. is the this the correct solutions?

It seems that the BPDU guard is enabled on all ports, How can i disable bpdugurad on that single port and not effect anything?

Will disabling BPDU on the switch cause any damages?

Thanks in advance

How to reset Cisco switches to factory

NOOB:

Cisco Switches: Various models.
As someone unfamiliar with these, I have been tasked with removing all configuration information from them, to return them to "stupid" or factory reset.
While I can find the makes and models and have a serial cable (attached via a USB) converter to my laptop.
I do not seem to be able to PuTTy in.
What connection I establish returns "garbled text".

The forums I have read all seem to suggest similar PuiTTY configuration settings - which I am unfortunately having no luck with.
I do not have any IP or config info...or I might have tried to TelNet.

I can provide more information if required - but this will give you a flavour of the issue.
Is there a default reset button - or switch - inside the case.

Any assistance will be gratefully received.

SERIAL (RS-232) TO BLUETOOTH OR ANT+

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

Remove old printer install/GPO

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?

Cat5E (RJ45) to RJ11 for a fax in a printer

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?

Is there a way on Palo Alto firewall to See what switches are connected?

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.

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?

Enterprise NAS Performance vs Windows Server

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

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.
