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 new to VLANs, I have a single CISCO SG300-10.  How do I configure 3 VLAN to create 3 separate networks which can communicate on the 1 SG300-10 switch. Would be nice to provide internet access.  I cannot tell step by step how to do this.  I have read the posts, but none match up pt for pt with SG300-10 interface. Not sure whether to use General or Trunk, Tag or Untagged.  

I am creating 3 VLANs on the SG300-10
VLAN 1 = default 192.168.1.254 on GE1
VLAN 10 = 192.168.0.250 =GE3-GE5
VLAN 20 =172.16.20.250 = GE7-GE9
VLAN 30 = 192.168.77.250=GE10

How should the ports be configured so the hosts on the VLANs can communicate with each other.   I keep reading the inter vlan should happen automagically, but it is not happening.

Simple, centralized multimedia control
Simple, centralized multimedia control

Watch and learn to see how ATEN provided an easy and effective way for three jointly-owned pubs to control the 60 televisions located across their three venues utilizing the ATEN Control System, Modular Matrix Switch and HDBaseT extenders.

I have a front gate on my farm that has 1800 feet of what I think is cat 3 untwisted 25 pair wire that was placed under Ground 10 years ago to operate the telephone connection and gate opener, the question: is there a way to wire this into my LAN in the house to be able to connect video Surveilance and or like a "Ring Doorbell" for internet access?

Is there a Cisco fanless 12 port or 24 port POE switch, gigabit?
I installed a 3750G-24 port switch in my office and the thing is loud, starting to get annoying.

I need at least 9 ports with the uplink, hence the 12 port minimum.

We had a Cisco Catalyst 1900 switch die this morning and need to replace it. My concern is getting the right fibre connections. What will I need to do if I want to replace the 1900 with a Cisco Catalyst 2960?

Thank you!

Hi All,

I am having problems loading OS image onto a new Nexus 9504 with 2 sup below are the steps i have tried, any advise would be much appreciated. image i am using is nxos.7.0.3.I5.2.bin

1. Reload switch and
2. Ctrl + C
3. cmdline recoverymode=1 and cmdline init_system
4. boot nxos.7.0.3.I5.2.bin (which is copied on bootflash/)
5. After this it starts configs and took some time but displayed other messages: System is coming up ... Please wait ...
6.After this, it returns to bash shell: bash-4.2# and nothing happens
7. Both switches, I have reloaded twice and retied again; but still same.

when i exit it takes me into (standby) login: but requires username and password which i have tried all the defaults and will not let me in.

Thanks

We have two different telecoms setup here. Anyhow, I want to move the Xerox machine with a dedicated line to another room. the dedicated fax line is using a RJ11 and ther eis also a RJ45 data port being used. The other room is setup for RJ45.

My issue is moving the dedicated Fax line. The line comes to the printer with no moving room. I'll either leave the box in place and use a longer Ethernet cable and wire it for RJ11 and move it to the other room. I haven't climbed into the ceiling yet to see if there is extra wire but I have to move it over 50 feet. I was thinking to leave the box in place and put a cable into the box and then feed it back up to the ceiling and run it across to the other room I need to put the Xerox in.

Does anyone have an easier way of doing this or any other ideas? I hope this makes sense...

Any questions please let me know.  I can also attach pictures...

I need to have a reliable power backup for my network server (and, if possible, for my workstations as well, although not as important).  I need some type of power backup that will not only keep my system running for at least a couple hours during a power outage, but also with the capability to be able to be remotely restarted (if necessary) after the power comes back on, if the power outage exceeds the battery backup time-frame.  My situation is going to be that I will be out-of-state and connecting remotely, working with a simple laptop, but need to have access to my computer network (approx. 3,000 miles away) for my daily work as well as maintaining a remote access environment for my users!  If anyone has any suggestions for me, I would appreciate hearing them.  TIA, Jim

Hello - we recently installed a new ASA5516 firewall, and have been having our US users access the ASA's public address in order to install the new AnyConnect software - which has been working.  We have a user in France, however, who is being blocked apparently due to the server not being trusted and a missing security certificate.  We do not have a security certificate for the ASA yet, so we're wondering if theres a way around this without having to install a certificate - like we do with the other US users?

hi ASA 9.1 (4)

make an audio call through ASA - weird on rare occasion i can hear audio. - then same call majority of times no audio.
the call is made from tablet inside lan  to phone on inside on LAN- it goes out ASA through to internet and back in through asa.
sip and h323 and skinny inspect ON. - Ive tried turning off makes no difference.

ports for audio open  8500-8598 UDP - how can it be a port issue if it works on occasion? unless some dynamic port happening?
is it something to do with NAT ?

thanks

I'm looking for some input regarding some recent spine/leaf design proposals I've come across. While a "traditional" S/L design would be to connect the enterprise campus core via L3 connections to the DC leaf nodes, what's been proposed are designs where all LAN distribution would also connect to the leaves, the S/L becoming a unified/collapsed DC and campus core.

Traditional
Traditional spine/leaf
Proposed
Proposed spine/leaf (collapsed LAN/DC core)
I'm looking to vet potential concerns around this design (if any). If a customer is also looking to handle Layer 2 extension/overlay across the S/L fabric to support VM mobility (a la VXLAN), does this present a problem? Or, would we simply define the ports that connect to compute resources as VTEPs and NOT the links leading to the LAN switching?

Again, looking to see if others are running across (or even deploying) these collapsed designs, where the before/after net effect is the removal of the existing campus core switching layer (and thus, savings in hardware expense).

Thanks again

Anyone has preferences and why?  Would it make sense to go with Cisco WAP Aironet, etc,   if the rest of the devices are Cisco.  Switches, routers, etc.

My GSM modem is not able to send or receive messages. The red light on it does not blink anymore, but just continuously is lit up. Whenever I try to send a message, it comes up with
AT+CMGS=(number)
>(message text in hex)→
ERROR
AT+CMGS=(number)
>(message text in hex)→
ERROR
AT+CMGS=(number)
>(message text in hex)→
ERROR
It repeats 3 times for every attempted message sent.
Any suggestions?

Hi,

I have a Cisco Air-Lap1042N-E-K90 access point but when I try to do a factory reset of this AP so I can configure it there is no option for conf t

I have followed the reset procedure and unplugged and pressed and held the mode button and the AP goes through it's startup until the LED goes to solid red,  At this point I release the mode button, The LED initially blinks green, then goes to blinking red and then continues onto blinking amber and then seems to stick in this loop after this stage I can ping the ip assigned when I connect an Ethernet cable but I still can't even login on my browser or conf t into it at CLI level either.

Is there something I'm missing here as I'm not fully conversant in cisco.?

Any help would be grateful
thanks

We are provisioned Two 2960x Cisco Switches and linked up with a FlexStack Plus cables/modules. All connected devices (e.g. Windows Servers) has two UTPs connecting to the switches, one to switch A and another one to switch B. The switches are implementing Channel Group using LACP where port from Switch A and Port from Switch B are belongs to the same Channel Group for network resilience purpose. Also, we have created TWO VLAN on the switches where each VLAN span across the two switches some network device are belong to VLAN 1 and some are VLAN 2. This is a floor level implementation and we have an uplink router (Core Switch) to route packet between VLANs.

We are planning to add more devices and we are running out of switch ports. Our expansion planning are as follows:

Option 1) Add another two network switches (i.e. 2960x) to the FlexStack cluster and create additional channel groups with switch port from Switch C and Switch D. So that the new devices can connecting to the new Switch C & D while still maintaining the resilience requirement as well as able to communication with the original devices connecting to switch A & B.

Option 2) Option 1 is only feasible if we have enough room to accommodate another two switches on the same rack. If however, we need to put the new two switches on another rack with is around 10-20 meters away still connecting themselves with FlexStack Plus, we are planning to purchase a 10G SFP+ module on the switches and link up Switches A/B …

I have a program that our organization uses to collect reports and recently the GSM modem has been unable to receive or send SMS messages. All AT+CPIN= codes return ERROR. AT will still return OK. When I configure the modem, it looks like this.
AT+CMGL=4
ERROR
AT
OK
ATE0
OK
AT+CPIN="****"
ERROR
AT+CMGF=0
OK
AT+CNMI=0,0,0,0
OK
AT+CMGL=4
OK
How do I fix this?
Any help would be greatly appreciated. Thanks.

Good afternoon Experts,

Our Security Manager asked me to upgrade his existing IP camera network from 10/100 to Gigabit from our Control Room to our guard stations, roughly 150 meters away. The existing network we have been using is 2 Comnet devices, model CNFE6+2USPOE. More details on this device here:

http://www.comnet.net/comnet-products/ethernet/self-managed-switches/cnfe62uspoe.html

I decided to purchase 2 Netgear, model ProSafe-GS110TP:

https://www.netgear.com/support/product/GS510TPP.aspx

Connected with TrendNET TEG-MGBSX SFP Modules

https://www.trendnet.com/products/proddetail?prod=200_TEG-MGBSX


My issue is that I get no link light when I set up a switches in both locations. I have tested the units side by side and it all works, but for some reason when I get them set up in their specific location I no longer get link lights. I'm using the existing fiber run that the Comnet devices are on, and have confirmed it's 50/125 fiber, and I've tested the new short fiber cables we bought and they work as well. The TrendNET SFP modules should be rated at 550 meters.

In my other experience things like this just fire up, then you make sure the VLAN's are correct, but in this case I get link down in the Netgear GUI and obviously no sweet flashing green light.

Am I missing the forest through the trees here?

Thank you for any guidance.

Title says it all. We need to configure multiple (12) tomcat servers on a single application server and are using a Barracuda model 340 load balancer. I'm not certain because I don't configure Tomcats, but is it just a case of assigning each tomcat an ip address and then defining all 12 ip addresses to the load balancer?

Dear, we found an old switch Cisco 2960 in warehouse, it still works when we plug in the power but we 'd like to make sure it will not suddenly die. So how can I check the health of that switch? Can anyone please suggest some commands to check:
- When was it used for the first time?
- How long can it be used?

We want to utilize it for a new project so please help! Many thanks!
