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?

Brocade FWS648G Vs 7.4.00 is there any on line documentation available or user groups for this switch?   Or can you recommend a current source that would work as well?

Hi,

I have a TP-Link 3150 v2 wireless ac router.

Does it support access point and repeater mode?

If not, please suggest some wireless ac routers that act/support in Repeater and access point mode.

Reach out to me for any questions.

Thanks for your support.

Warm Regards,

I have a cisco 3750G POE 24 switch, and it's not booting.  I have uploaded a new IOS via TFTP, did a reload, and now I'm at the switch: prompt
I have included a picture, I have tried a few things, but nothing I'm trying worked.  Any suggestions how I can get the switch to boot correctly?

Best way to configure spanning tree on HP Procurve switches

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

It's not just about Wi-Fi connectivity anymore. A wireless security breach can cost your business large amounts of time, trouble, and expense. Plus, hear first-hand from Miercom on how WatchGuard's Wi-Fi security stacks up against the competition plus a LIVE demo!

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

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.

Hello there,

Can someone help me locate management packs for HPE Aruba Switches? Alternatively, easy to use documentation on how to incorporate its SNMP into SCOM (System Center Operations Manager) would be helpful too.

Hi,
I have a working WLC5508 which I want to replace with 2 WLC 3504 configured in HA.
I'm trying to figure out how to proceed with having the 30 AP now managed by WLC5508 move to new WLC3504. What is your suggestion ? Do I have to cope with a disruption window time ?
What about having APs survive in case of WLC3504 sudden death ? Is Flexconnect the answer to this ?

thanks

Hello,

Question on HP C3000 server-chassis:
- Just to be clear: I know only a C7000 has automatic failover for the interconnect modules in the back.
- But I have a C3000 chassis (partnr 437504-B21) currently 1 Gb connected with 3 HP ProLiant BL460c Gen8 v1 blade-servers (partnr 655492-004) in it. They used to be sitting in a C7000 chassis with a 10 Gbps FlexFabric module in the back. So they have the onboard 10 Gbps FlexLOM (if I remember the terminology correctly).

The question is: I want to repurpose these servers and the chassis. Is there a way I can connect them in this C3000 chassis over 10 Gbps with a backup/failover at the hypervisor level to a 1 Gbps connection? I just want to be sure whether that is possible and what I need in terms of mezzanine cards etc.

Thanks

https://www.experts-exchange.com/questions/29118598/VONETS-VAR11N-manual-driver-functionality.html

Just received the Vonets device & tried the above suggestion of setting it to "Bridge + Wifi repeater"
followed by steps in page 7 & 8 below:
https://www.manualslib.com/manual/1044556/Vonets-Var11n-300.html?page=7#manual
https://www.manualslib.com/manual/1044556/Vonets-Var11n-300.html?page=8#manual

Q1:
I'm able to use it as Wifi repeater ie by placing it say 12 ft away from my Wifi broadband
router & with my laptop is a 'blind spot' of my bedroom, my laptop could connect to that
device "wifi hotspot" & get to Internet (which previously my laptop cant get to Internet).

Now, the other requirement as per the original enquiry in the EE link is to connect it to
a LAN port & serve as Wifi hotspot: can't get this working: when laptop tried connecting
to this device's SSID, it prompted for password which when I enter, it simply gave the
message "password not right" though without connecting this device to a LAN port, the
very same password works.   I've tested connecting the built-in LAN cable to LAN port
OR (ie one at a time) using a LAN cable to wire the WAN port of device to wall's LAN port.

Q2:
If this works, the next thing I'll need is to connect this device to my laptop (while my
laptop is connected to a LAN port on wall & serve Wifi hotspot to others

We have Brocade 5100 switch which is failign to boot and all the ports on the switch are yellow.
I conected the console cable to the switch and saw the following output:-

After this there is no more output on the console.
I looked at on of the Brocade SAN Health software reports and it showed a failed power supply fan.
We had a power failure due to which this switch got shutdown and has been in the above stated status since then.
Will it be the failed power supply causing this?
Is there a way to be 100% sure that this power supply is the cause of switch not booting up as then we can buy the power supply.
What else can cause this and what …
