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 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.

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

Do not have experience with Juniper routers.

Have TeraTerm running on the laptop connected to a Juniper CPT2024 router on Com Port 2 which I understand to be the console port.

Ran every baud rate on the list. Still getting gibrish on the screen.

Once I get a command prompt, need to get in and clear the flash, and delete the configs, and prepare router for resale.

Hi guys,

I got a microtik - rb2011uias-rm model router board.
i got 2 questions.

1 - i created few deny policies from  external ip to my internal network. but i got many policies for each wanip. is there any way i can create like a group of wan ip. and make it a single deny policy ?     (right now i got many deny policies(1 policy for 1 each wan ip - i want it to reduce it))
2 - my router keeps logging me out for every few seconds. i can login again and make changes, all works . but it keeps kicking me out for every 30-40 seconds. anything to help me with this ?

NEC SL2100 phone system started behaving poorly a week ago Sunday.  Rebooted all network equipment, and nothing changed.  Reboot the phone system and everything worked for about 20 minutes.  Same cycle of events, about same time frame.  Next checked all network equipment for firmware upgrades.  Wireless bridge Engenius EnStationAC went from 2.x to 3.1.2.11 on both sides successfully.  Problem returned yet again, but now a delay in getting dial tone of about 3-10 seconds.  If phone hangs up and connects immediately, no delay happens.  A monitoring computer is the only non-phone device on the entire voice network.  It shows random packet loss to phones.  The phone problem was originally they begain restarting at random.  They are not all happening at one time.  The delay never happens to VOIP phone on the system side of wireless bridge.  Engenius has yet to comment on the issue.  One phone (Only one phone) peforms IGMP actions accoring to Wire Shark.  Removing that specific phone solved the problem for almost 2 hours.  Yet it eventually returned.  All the time I have brought another laptop in for testing and moving it to both sides of the bridge.  If I am on the system side, I perform ping tests to the phones on the far side of bridge.  If I am testing the phone system resources, I am on the opposite side of bridge.  I perform around 1,500 packets to 3 devices simultaneously each time I test.  No latency or packet loss ever.  I have introduced a new PoE switch on the system …

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 …

I am trying to migrate from a 6120XP fabric interconnect to a new 6332-16UP.  I understand that there is no direct migration however, I do not want to lose my settings, pools, profiles etc., as I have never installed an FI out of the box.  The new FIs are up, however I do not know what to do from there.  I am looking for some help including step-by-step instructions if possible.  Please advise.

I'm attempting to connect some switches in my IDF locations to my MDF switch via SFP.

The fiber connecting each IDF to the MDF is multimode, OM3. It connects to a LANscape housing in each location. From the housing, I'm trying to connect a fiber patch cable to the SPF module on the switch.

I managed to get ONE switch working in ONE IDF by using an aqua OM3 patch cable connected to a Ubiquiti module. The only way I could get that connection to work was with a multimode fiber converter in the MDF connected to a port on the switch. SPF would not work. I've tried various SFP modules, including an SPF+ 10G multimode, a Trendnet 1.25G multimode, a generic 1.25G multimode module, and even a couple single mode SFPs, just in case. I've tried aqua OM3 patch cables, orange OM1 patch cables, various LC to SC adapters, and some yellow single mode patch cables, again, just in case. I've tried just about every single combination of the above in some fashion.

On a second switch in a second IDF, even with a fiber converter in the MDF, I can't get a link. If I remove the converter from the first connection in the first IDF, I can't get a link with any combination of the above.

I am about to go insane with this problem. This should be straightforward and easy, but it's driving me nuts.

The contractor installing the actual fiber backbone has told me it's multimode fiber, OM3, 50 microns. I suppose that might be incorrect information, but I have had no issues or inconsistencies …

I have a small family computer business which now consists of just me.

Most clients are on a break/fix ad hoc support method either remotely or physical
site visit. It is diffiicult to sustain this model and I am looking at the best way of moving
to a montly support contract - though this will prove difficult.

What is the best way to achieve this though I know the majority will
be reluctant to pay a monthly fee.

Thanks in advance

A ubiquiti Fiber switch connected to a Meraki MS 42 is showing VLAN mismatch errors.  

from the Ubuquit, two fiber ports are aggregated to two 10G fiber ports on the meraki.  Meraki says there is a VLAN mismatch.  I cant see the discrepency.  Any thoughts?  Have rebooted Unifi Controller, fiber switch, meraki etc.

For example: camera 172.28.0.110 should be added to right below Gateway Media SSM-RS30 like other cameras in the first screenshot; however it could be only added outside of SSM-RS30 like the second screenshot.

Could you please suggest? Does anyone have experience?
