Hello EE,

I am trying to explain to management the need for a fire suppression system in the new data center.
I am being asked to provide a representative timeline and milestones to get a data center back up in the event of a fire.

Does anyone have a real life example as our options are:
1. fire suppression
2. enough bandwidth to mirror all sites to another site so could work remote via VPN (but the bandwidth for 1TB-2TB files can easily offset a fire suppression system cost)

hello experts
i have 3 SSID configured on an autonomous Cisco AP, all authenticate against ACS server, so three policy for each SSID, i did configured DNIS as *WIRELESS_SSID in "End Station Filter" but looks like it only works for WLC not autonomous AP, and seem Cisco autonomous AP not sending SSID info to ACS while the processing of authentication, my question is how to make Cisco autonomous AP to do this, i did try the following:
radius-server attribute 32 include-in-access-req format %h
radius-server attribute 30 original-called-number
radius-server vsa send authentication
but it doesn't help, please give me your suggestion.
thanks

What do you use when you need to run a cable through a wall or from the outside of a building to the inside of a building? I want to put in some kind of "grommet" just big enough to get one network cable (with ends) through. The walls will vary in thickness.

   My first thought was to put a short PVC pipe through the wall then find some kind of "flange" to put on both sides of the PVC pipe to hold it against the wall on either side. Surely there is something out there that is a "professional" way of getting a cable through a wall or from the outside of a building to the inside of a building. I just don't know what it is :)

Hi
I have installed several cat6 Ethernet cables around our office, nothing exceeding or anywhere near 20m
The devices, which are all 1Gbps capable, refuse to connect beyond 100Mbps
Could it be my RJ45 connectors or sockets that are of poor quality ?
thanks

We have a few Cisco 9300 PoE+ 48p switches distributed across a facility. We have many PoE devices that are working such as Mitel PoE phones and Aruba access points. However, we have a few devices that require PoE+ and they don't seem to be getting power. When I first started working on the issue I thought it might but just 2 devices so I set the power on the ports to the manufacture's specs. Now that I found that it is more I'd really like to see if I can figure out if it is a power negotiation issues. On the switch listed below is an example of one of them. You can see the static ports and then the other port that has the device but isn't providing power is Gi1/0/35.

We have a scheduled power outage in the small remote office.  Mostly network gear.  Few switches and firewalls.  No servers.
I know the UPS wouldn't be able to hold that long.  
What's should be the advised steps?   Shutdown the equipment prior to the outage and have someone onsite to startup after?  
How other folks doing it?  
Thanks in advance

Can you see if reasonable to have 2-post rack this way?  Attached.  Any other pros/cons please?  Designing server room/lab.

I have a server with multiple virtual servers on it, was wondering is adding a network card with more ports will help for performance, since I use gigabit switches so the most throughput on the network is a gigabit how will I gain with a card with 4 ports each a gigabit if the switch highest capacity of the switch is a gigabit plus the switch is handling not only the server?

Any recommendation for a nic card and if not much more expensive can do nic teaming.

Hello - need ideas/options.  I have two large juniper 9000 switches to mount to 2-post racks.  Each switch is about 130lbs.  Is it possible to achieve that?
I know its possible to find shelves but not clear how to secure it.  Please advice if possible at all.
Thanks in advance.

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

can anyone please advice me?
i need to get this to work .

I am about to set up a 4 mile wireless bridge.  The customer's inventory software provider says that the remote office must have at least 100mbps speed on the LAN, just as if the remote office staff were in the main office with their PCs cabled directly to their switch.  They don't need to know about WiFi performance in the office, but rather just the speeds between the PCs in the remote office and the server in the main office.  I need a recommendation for an app that is easy to use and addresses this need.  If it costs something that is fine.  TIA

We have purchase the new Aruba 2530F and our HQ instruct us to create the SVI’s in the switch and perform the intervlan on this switch. I have some doubt regrading this configuration and hope that expert can advise me.
1.      For all the printer we should use which vlans
2.      From the switch I can see that have option for us to check primary and management in vlan interface, let said in this information provide by HQ should I enable “management” in  VLANS 4
3.      What is native VLANS
4.      We try to enable the management in VLANS 4 ,we lost access or web console but we still have connectivity ?
5.     we should connect all the configure all the management port in VLANS 4 ?


MGMT_VLANS: 4        10.10.4.1
OFFICE_VLANS: 5(Native) 10.10.5.1
STAFFWiFi_VLANS: 6         10.10.6.1
GUESTWIFI_VLANS :7        10.10.7.1

What power parameters do I need to know before bringing the equipment into the server room?  Want to make sure I plug things in and not kick the breakers.
I'm bringing two large switches, two large firewalls, and UPS.
Do I need to ask electrician for watts available, or Amps, or VAC?

I have a Singamax cat 5e patch panel connected to a Cisco 24 port gigabit switch and my machines which have gigabit cards are only connecting at 100mbs?  Any ideas?

I have a client with allworx phone.  The moron didn't asked what type of speed we are running so we went from 1gb connection to 100mb connections because they connected the PC to the phones. I'm not sure if I have enough IP jacks to move the phone to a separate connection.  I was told there are splitters that will allow 1 gig for the PC.  Does anyone know about what the splitter is and where  can purchase?

Does anyone has experience with flashing your own fiber optics SFP?  I see some network engineers using this.  Flexoptix.  Instead of buying brand named optics from the manufacturer.  They make their own for fraction of the price.  

https://www.flexoptix.net/en/flexbox-series-configure-universal-transceivers.html?395=1357&co9424=

You need to buy a flexbox to code the optics. ~$2K/each.

I've never done this before and not sure what entails.  Is it the best player on the market?  Any risks or other issues doing it?  
Please advice.  Any info appreciated.  Thank you!

Hi all,

I have a client who has their internet connect/modem setup in the wrong place. They have Australian NBN, fibre to the node which means they need a telephone line going to the modem. They would like to move this and I have been asked if they can use the existing ethernet Cat5e cabling to run the telephone line for the modem. Can this be done?

What are the best fiber cable manufacturers?  There're so many online and price varies and lot.
Looking for LC/LC SM and MPO MM cables.  
Please advice.  I normally buy on Amazon.

How do you test the network speed between computers connected to a switch?

Is testing the Internet speed the same thing?

We had a 2016 server yesterday that could not connect to the Internet.  I found one of the NIC adapters did not have the Default Gateway setting.   After adding it the server was fine.

Now again today the same server has lost the Default Gateway.

What would cause this?

Hey all
Moving to a new office, was going to go with a TZ400 for a router/firewall/vpn solution.

Have two separate factory areas, both have metal covered walls. We are going to want to have Wi-Fi in each of these rooms for the factory workers handhelds etc.  Ceilings could be 24’ ft plus, I need solid reliable solution that just works for Wi-Fi.  It would require multiple points so therefore a controller to hand off from point to point as they make their way around the factory floor etc.  Hoping for simple/reliable – easy to administrate.  Thoughts/ideas?
Thanks!!!

We were given a network with no idea of the subnet structure. What I am essentially looking for is a MAC Address Scanner that will go through every MAC Address known to man and report back the found MAC Address and corresponding IP. I realize it will take a long, long time to do.....
