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.

Hi,

Our company internet provider set us up with a new modem which would deliver faster speeds and has the IBGP failover ability. In order to use the IBGP failover we would need to designate 1 (or 2?) IP's from our small block of IP's, or get rid of the current ones and use a larger block of IP's.

Does it make sense to just consolidate our current IP's instead of purchasing a larger block of IP's? We currently have 5 public (outside of the broadcast)

Is it best practice/ industry standard to purchase larger amount of public IP's?

Thank you.

Physical Parts of Control/Data/Management Plane.

reading about Control/Data/Management Planes , if I understand :

Control plane is where the Routing table is built.
Data Plane or also called Forwarding plane contains a copy of RIB
Management Plane , I am not sure what it is, probably it is just the interface of the router or the switch to which we connect to.

What I need to know, is the hardware that the above elements run on.

for instance does Control  plane encompasses CPU , Memory , or it is completely different Chip ? the same question applies for Data plane and Management Plane, on which hardware do they run on?

Thank you

I have  cisco switch, a 3850 and created a port channel for 3 ports.  Each port is a 10G port.  On the other side, I'm using a synology with 4 (1G) ports. I did a LACP on that side as well and bonded 3 of the ports.  It shows the link at 3000 Mbps.

On the cisco switch, the port channel shows a speed of a-1000

Not sure why it's only connecting at 1000, but when I did a speed ?, it only gives me the options of 10, 100,1000, auto and nonegotiate.  I tried auto and it puts it back to a-1000.  I tried nonegotiate and it didn't take that command.  So how do I get the port channel to run at 10G, so it can at least transfer at 3G?

Dear Experts
We had to install Cisco FMC as VM appliance on VMware the engineer completed this task. But in the vmware web console in the status it is showing as “Warning” and also following event message
1.      The configured guest OS (Other 2.6.x Linux (64-bit)) for this virtual machine does not match the guest that is currently running (Other 3.x Linux (64-bit)). You should specify the correct guest OS to allow for guest-specific optimizations.      Warning
2.      Another issue is when we shutdown the FMC safely and again started due to server maintenance later now turned ON but it is more than 4 hours still it is showing up “System processes are starting, please wait. “ when accessed the FMC.
Please help on how to fix the above 1 and 2 , thanks in advance.

We have been having an issue with specific websites being slow for almost a month now.  Certain sites (mymathlab, our library system, and various other sites you log into) have been slow when sending or recieving data.  You click a link and sometimes it spins and spins and spins.  We are working with our firewall vendor Sophos (it seems to have shown up after a firmware update) and we are very hesitant to downgrade because that often can cause issues in itself.  

Normal website browsing is fine, seems to be stuck to sites you log into that are hosted off campus.  Any thoughts?  We have 2 internet connections load balanced behind an ISP load balancing device. I am interested in all theories as this is causing significant hardship for our students and staff.  Thank you all very much for your insight!

Hi all,

I have an Overture 1400 chassis that I have been unable to password break to set back to factory defaults. I have tested something similar to this, using the password/username combination superuser. Unfortunately for me this combination in it's many forms does not work. From what I could find online there isn't a lot of documentation out there that has proved useful. I have tried a number of other username/password combinations, none of them have worked.

The vendor that we bought them from will not share password information.

Any suggestions would be much appreciated.

Thank you,

Mara

Hi experts!

I work for an OEM vendor, who for now shall remain nameless :)
We use Sierra Wireless EM7430 (4G + GPS) modules in some of our laptops.

For one particular client he is having 60+ % units regularly "crashing". Not a fatal crash, because a reboot "fixes" it. Until next time :(  

This issue does not occur with a factory image, so probably, it is a problem within the client's SOE. The client is using Microsoft Direct Access as their VPN. Their SOE is based upon Win 10 Enterprise v1809.

The issue is particularly troublesome in that it is intermittent. All seems good and then when their field techs go about their work the 4G network drops off, seemingly with no rhyme or reason. And without visible indication, too, so the field techs continue working without realising their data input is not being recorded. The 4G icon in the Notificaction Area either get s an exclamation mark or it disappear altogether. However their staff don't generally see that as their main ERP app is fullscreen. As stated, a reboot temporarily fixes it; but then they lose any cached data. One thought we had was the problem occurs when the cell service goes in and out (can be common here in Australia). We have tried replicating the issue by sticking a laptop into a microwave (it's like a Faraday cage haha). Cell service dropped off, but no driver crash. Another thought was that maybe when the 4G goes into band 28 / 700Mhz (also common in Aust) maybe that creates a problem. Don’t know …

I have Linux 8 enterprise running on Oracle VirtualBox 6.0.10 and the network connects but I can get any traffic outside of the VM. When I run IP ADDR to get which networks are valid and then I run IFUP for those that show down I get Error: Connection activation failed: No suitable device found for this connection (device ### not available because profile is not compatible with device (mismatching interface name).

I have been going through what I can find on the web with no luck, any help is appreciated.

Hi,

Our customer has one room which has router in it and another room which has a PC and printer in it, but in this room the WiFi internet connection is not great.

To solve this issue, we installed AV2000 Gigabit Powerline ac Wi-Fi Kit TL-WPA9610 KIT in the room with PC and printer which has boosted internet connection and signal in that room.

We plugged in one PowerLine WiFi adapter near the router and WiFi extender in room beside printer and PC.

The WiFi was connected and two PowerLines paired.

We would like that if any problems happen where internet connection is lost and comes back, that these PowerLines reconnect themselves.

1. Will these PowerLine devices reconnect to WiFi if:
    - WiFi extender is relocated
    - Router loses WiFi connection and reconnects after few minutes
    - Both adapter or extender are plugged out and plugged back in after few minutes
    - Adapter is plugged out and plugged back in after few minutes

2. We have heard that one day, a few people tried to connect to internet where WiFi extender was but internet connection was lost. The next day we reconnected fine to the internet. What could be the reason for this?

Thanks,
Robbie

I would like to run a single CAT 5e/6 cable to the center of a beam in a classroom to feed a wireless access point. The classroom has 4 florescent lights, in a square, surrounding the center of the ceiling.
Due to the type of older ceiling, there is no way to run the cable from the top of the ceiling.  Is there a way I can shield the cable from florescent light interference?lightinglighting2

How can we find out what the Power over Ethernet settings are on a switch?

Our Wireless Access Points are working very well; but, I have 1 AP that is not working at all and the vendor is asking me to look into the POE settings on the switches.  I tis showing an Amber LED light for the system LED.  https://fccid.io/Q9DAPIN0344345/User-Manual/Users-Manual-3573189

The thing is that all of the AP's at this location are showing an Amber light for the System power.  All of the other AP's are working great; hence, I think the Switches are 802.3af POE source.

Quesiton1:  How can I verify the HP Switch is an 802.3af POE source?  Or that Intelligent Power Monitoring is enabled?

Dear experts.
im having a serious storage problem.
for a client of mine i built a ZFS (linux)  storage system based on NVME disks. to be exact intel p4600 disks.
here are the system Specs.

storage controllers 2x
Hpe DL380 G10
256 GB memory
2x Xeon Gold 6154 procesors.
Mellanox doual port Connectx-5 VPI 100GB network card (ethernet Mode)

the network switch connecting the ESXI 6.7 servers to the Linux/ZFS storage is a 100G Mellanox Sn2100 switch (dedicated san)

the problem however is that the performance is so super slow that its just a bit higher than a 25G network card can offer this is on both ISCSI and NFS



i searched the internet for days and tried every tuning manual possible for Mellanox on Linux. but i still cant tackle the problem. the performance is very very slow.
can someone Help me?

also an important question. Can i use RDMA/NFS for ESX? i know that i can use RDMA/ISCSI through ISER but can i use NFS with RMDA?

in the testing phase windows was installed on the system and we benchmarked the disks and were able to get 15GB/s reads and 13GB/s writes which is great for an NVME raid of 6 disks. (all software raid). also worth mentioning i tried benchmarking the SAN network with these very same controllers with windows installed using normal network sharing of folders and i was able to score a full 9.6GB/s of transfers wich is almost the limit of the 100G networks

We have a 300 meter OM3 50/125 Multi-Mode fiber with LC connectors running in our building. We are adding two new switches, one on both ends of the fiber (Netonix WS-12 series). We are wanting to create a 1G uplink between two SFP ports of the switches using Ubiquiti's multi-mode SFP fiber modules. We have been unsuccesful in getting an uplink between these two guys, but when we go switch to switch without the long fiber in the middle we get lights. What could I be missing that could maybe cause this to be happening? Any direction would be appreciated and I will do my best to fill in any missing information. Thank you!

Hello,

I have a very strange issue.  I have 2 juniper switches that can ping each other's gateway addresses fine, I can ping from in both directions from both sites core switches, so there is no routing issue.,see below.

However I cant ping server to server with the "source: 10.10.0.20" and "destination: 192.168.151.21".

Yet I can ping in one direction successfully from core switch 192.168.151.251 to server 10.10.0.20 successfully, just not the other way around??? What i am missing???

In a business that is spread over three buildings, I am trying to connect Unify NanoStations to extend wireless access from the first building in which the ISP comes into.  From the ISP's router, I have an unmanaged switch connecting to a Nano mounted on the outside of the building where the ISP comes into.  From there I have it pointed to a second Nano mounted on the second building through another unmanaged switch and a Unify AP is also connected to that same switch within the second building.  Internet is working fine in the second building.  A third Nano is mounted on the second building with another unamanged switch connected to it.  The fourth Nano is mounted on building 3 with a fourth unmanaged switch and a Unify AP connected to it.  Initially, building 3 connected fine and also connected without the third Nano's help for a short period of time.  Recently and presently, I get a blinking light on the AP and no Internet connectivity.  All devices are setup to talk on a 192.168.2.x network.

I have 3 Smart-UPS 1500 with what i believe are AP9630 UPS Network Management Card 2 in each one. We recently had a power outage where the main network switch lost power before the ups's shut down. The UPS network card was trying to send notification emails but could not due to no connectivity to the email server. Now when the UPS sends out email such as a self test passed, the email that gets sent out is 2 or 3 email notifications old. It like the email is queued in the network card and when a new email event is generated, it sends the oldest one out. Is there any way to fix this so that the email being sent out is the actual event vs an event that is 2 or 3 events old?  Prefer a way to do this without shutting down ups..

Trying to use Trendnet Wireless Bridge with an Aruba IAP-205-US as the AP.

I have a small office in a warehouse that we want to run a few desktops off of using  Trendnet TEW-740APBO connecting to a ceiling mounted Aruba IAP-205-US.

The Trendnet connects and If I assign a static IP to the devices, it passes traffic, but DHCP does not work.

I can't find anything in either side Trendnet or Aruba that should block or allow this.

There is a small environment with a Domain server, a handful of computers, and a few POS terminals.  After a power outage a few weeks ago, the modem was replaced by the ISP.  The internet would be available for about 15 minutes then it would be gone until the switch between the NSA and the internal network was power cycled.  Initially we thought that the switch had gone bad, a new switch yielded the same results. If we reboot all the computers it will work for a few days or so.  Has anyone run into this and found the issue to be something specific happening?  I have rebooted everything from the modem through the PCs as well, that also only gave them a few days before it started dropping out again.
