Networking :: Basic Vlan Stuff With FS726T Switch

Feb 13, 2011

Its just a basic question, I have a FS726T switch, and wanted to know how the clan thing should work.

Group A are ports 1-8
Group B are ports 9-16
Group C are ports 17-24

Internet is on port 26

I want each group seperate so 3 vlans... but does port 26 need to be in all 3 vlans for.them to receive internet? Is it possible to have 1 port in 3 vlans?

Would that keep them from seeing each other and still access the internet?

Cisco Switches :: SGE2000 Best Switch For ISCSI / Basic VLAN?

Jan 19, 2013

I currently am using the SGE2000 switches for our datacentre and they have run great. We are looking at replacing them as part of our normal equipment refresh and have questions about what is the best switch for us. We are looking at upgrading to at least 48 port switches which isn't a huge issue.The main purposes of the switches will be for iSCSI traffic between Starwind SANs and Vsphere 5.1 hosts. We had some latency issues with one of the SGE2000s but otherwise they've been great.
We also will use these switches to handle our feeds from our ISP and our normal interserver communications. We have had DDoS attacks in the past of 40k packets per second and 600mbps and the SGE2000 never even flinched. We don't need it for any layer3 routing (which we use virtualized PFsense for). Looking at the Miercom report the SG200 series looks like it would be fine for us but I'm just worried around the part which mentions it becoame unresponsive in a DoS attack and also whther it may be slower for iSCSI. Both series seem to support flow control and jumbo frames.

Netgear FS726T Switch And SMC Cable Modem Connection?

Jan 27, 2012

I am relatively good at installing and troubleshooting smaller sized networks... I am having trouble with one of my customer's networks and I think I have the problem narrowed down. r issues.I have a customer with a FS726T switch and ~20 computers connected to this switch running DHCP assigned addresses.The switch is assigning addresses in the 10.0.0.xx rangehe customer currently has an old T1 line coming into a Cisco router, which then directs traffic to port 20 on the switch.The problem is, we are replacing the old T1 line with a newer 50mbps cable connection.The cable company pre-configured their router with a static IP address the 68.116.xx.xx range. The Subnet is also different than the Netgear's subnet. I would like to keep the old T1 connection in place. I believe they have data that needs to go to their mainframe/backbone server at corporate.

I cannot log in to the cable modem. IT is an SMC SMCD3G with a staic IP. I tried changing my PC's IP address to the same gateway but cannot get into the cable company's modem, even using a static IP with the same gateway as the modem's gateway address. I don't want to reset the modem/router and lose the cable company's settings.I am pretty sure for the devices to communicate, the following has to be true?:1) Cable modem and FS726T must be on the same 10.0.0.xx IP range?2) Cable modem and FS726T must be on the same subnet mask?

I am an accomplished developer in Microsoft technologies, however networking has always been my weak point. I have always managed to be in jobs where my lack of knowledge in networks has not affected me, so I have never bothered to learn anything.Are there any good books out that would teach me the basics of things like tcp/dhcp/vpn/dial up networks/routers and other netwokring terms.

Home Network :: Basic Networking Terms And Devices?

Mar 28, 2012

Modem - (MODulator/DEModulator) This converts your xDSL analog signals into a digital format for use on your home network. A modem can also be part of a Router/Modem combination device.This device typically sits at the very edge of your network at your ISP's demarcation point (the point from where their responsibility for equipment ends).

Router - A router serves to 'route' information from network to network. I.e. A router will route information between the network and Generally your home routers will come as a modem/router/wifi access point package. It will basically route packets of information that are generated on your LAN (Local Area Network) to the internet, and in turn, route packets from the Internet to your LAN devices.

Wifi access point - Obviously provides a wireless Ethernet signal so that you can connect wireless devices to your home network. Typically, the wireless access points you will see will come as a combination of router/modem/wifi point. You can buy extra wireless access points (not wifi routers) and place them strategically throughout your home to increase signal coverage.

Switch - Uses hardware addresses to 'switch' packets through the LAN. Normally a domestic router will have 3 or 4 switch ports built into it. However, switches do come as standalone devices and can be used to increase the breadth and scalability of your home network by using the extra ports they provide to patch in more devices.

Host - A host is basically your PC, iPad, smart phone, laptop that is situated on your home network.

NAS Drive - (Network Attached Storage) Contains storage space that can be used as network a share by connecting it your home network.

NIC - (networt interface card) this is the component that allows your PC/Laptop to be hard wired into your router or switch. It will have an RJ45 jack so that you may connect Category5 and onwards patch leads into it from your router or switch. This talks with your computer's main motherboard and operating system to give you network connectivity.

MBs vs Mbps - MB = Mega Bytes (this measures file size) and Mbps = Mega bits per second (this measure network throughput).

Wireless card/receiver - as above but wirelessly.

Networking :: SG300 Guest Vlan Are Not Available

Apr 15, 2012

I know "Guest Vlan" aren't available on SG200, only SG300 have that feature.Problem is i only have a SG200 on hand and no extra budget.

We have multiple vlan:
vlan10: LAN
vlan20: Voice
vlan30: Guest
vlan50: Servers
vlan100: Lab1
vlan200: Lab2

Since it's a small business and lot of people moving around, doing test, etc.... most port are tag with all vlan. Our Wireless AP have multiple SSID one with vlan10 and one with vlan30 for guest.

Is there any way without the "Guest vlan" feature that i could have with my equipment any equipment without a vlan configuration be set on vlan30 ?

Cisco Switching/Routing :: 3750 - Extending VLAN To Remote Switch That Already Has VLAN ID In Use

Jan 10, 2013

I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
SITE B - Cisco 3750 L3 - VLAN ID 50
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.

Cabling / Cards :: Could Not Re-open Realtek Stuff

Apr 14, 2011

I bought a reconditioned Dell Inspiron 1000 which had the above loaded. In fact, everything was ready loaded on the laptop, so I do not have any disks. My laptop started jamming and so I closed down all things open on it, which unfortunately included closing Realtek (which seemed to be always open). I then could not 'reopen' the Realtek stuff loaded, it wouldn't let me.I am using a Belkin wireless g card in the laptop which came supplied with it. I thought the Realtek stuff was to with this. My internet connection keeps failing for no reason now.I don't actually know what the Realtek software/drivers/whatever were doing.

Cisco :: LMS 4.1 How To Troubleshoot System Related Stuff

I have been in charge of CW and now LMS 4.1. Since I am not a system engineer in profession, it has always been difficult for me to understand how to keep databases and log files in order and how to troubleshoot system related stuff, without causing any problems.I mean that besides setting jobs (device discovery, netconfig, usertracking, archiving and the like), what else do I need to check on a regularly basis, which jobs can I delete with safety, what kind o log rotation should I configure?For example, I have noticed that the ConfigMgmtServer.log is quite large (1,2 Gbytes).

Routers / Switches :: Losing Internet Connection And Stuff?

Sep 26, 2011

It is set to dummy mode so it should just pass through to the WRTG54S router which handles the DHCP.2) I have 6 computers sucking the internet off of the router. One is wireless.3) I have been set up for about 6 months this way. 4) I use to drop the DSL connection about twice a day. I would unplug the WRTG54S and plug it back in and everything would reset and work. Then, recently it has gone to about 15 times a dayThen, we have to make a major electrical change in the building, which required us to go to generator power only for 5 days. For 5 days, we never dropped the DSL connection a single time. Power was restored. Generator sent back home. Problem is back. Dropping DSL connection again.5) Hooked up APC battery backup power smoothing device to 3 cpus, WRTG54S, and DSL modem.

Networking Limitations Of A Consumer-Grade Switch

Dec 24, 2011

So, using a standard off the shelf UNMANAGED gigabit switch (just a cheapie), I have a scenario that I need to know about before I go and buy a whole lot of equipment.Ok so let's start off and say it's a perfect world and the workstations connect at a full 100 Mb/s and the server connects at 1000 Mb/s.So I'm looking at having say, four or five workstations connected to the gigabit switch (at 100Mb/s) and also a gigabit connection from the switch to the server. In this scenario, taking into account everything I've said above, would each of the workstations get a full 100 Mb/s to the server, or would everything be limited to 100 Mb/s total? I could see potential for the server to only talk to one of the workstations at a time and only at 100 Mb/s, but hopefully all four could communicate to the server simultaneously.

Asus RT N16 - Would Fast Ethernet Switch Slow Down Gigabit Networking

Nov 4, 2011

I have setup an Asus RT n16 with 3 computers that support gigabit ethernet and a media server on one floor. On the other floor I have set up a fast ethernet switch (connected to my asus router) which is connected to several fast ethernet enabled computers.

Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?

Home Network :: Multiple Router Networking Versus Adding A Switch?

Apr 22, 2011

on my home network I currently only run an Airlink101 AR675W router. We have a couple issues with this. The router for one is in my basement and there are points in my house that have low signal strength, especially upstairs in the far corners of the home. Second is I am currently running my home PC as a media center but it is set-up wirlessly so streaming is clunky and jittery. Also on this network is 3 X-box's wired, a PS3 running wirless, 2 PC's wired in, 2 wirless laptops and the afore mentioned wirless PC. A lot of weight for the network. What I want to do is move the router upstairs, hardwire it into my wireless PC (the one doing the streaming) and connect a second router (an identical make and model I am buying this weekend) downstairs which will be basically used as an "expansion" of the wirless and a switch for the hardwired devices downstairs. would this be better than simply moving the wirless router upstairs (hardwiring my PC) and putting a 5 or 8 port switch in downstairs for the X-box's and 2 wired PC's there?

Networking :: Zywall USG200 Internet Connection If Modem And Switch Got Switched In

Nov 25, 2012

I got a retired Zyxel Zywall USG200 from work. Its working just subs ran out. Was thinking of putting it on my home network, any reason not to? I'm a sys admin, not network engineer, so while I'm capable I'm not an ace with this type of equipment.. Which is why I want to mess with it. I'm currently RTFM and it seems pretty straight forward. If it seems like a viable piece of equipment I'd like to use it full time.
How bad can I break the internets and subject myself to the wrath of my wife's downed internet connection =D if I plug it in between modem and the switch?

Cisco Switches :: VLAN With 2 Switch ESW - 520?

Jun 13, 2011

For test I used 2 Switch that name "ESW X" and "ESW Y" I have 2 network that I named "Network A" and "Network B" I build 2 VLAN for each network that named Vlan 2 for Network A and Vlan 3 for Network B, I don't use Vlan 1 because it's the default Vlan 
Configuration ESW X:
port e1 : ACCESS PORT on UNTTAGGED Vlan 2
port e2 : ACCESS PORT on UNTTAGGED Vlan 2
port e3 : ACCESS PORT on UNTTAGGED Vlan 3
port e4 : ACCESS PORT on UNTTAGGED Vlan 3
port g3 : TRUNK PORT with UNTTAGGED Vlan 1(default) and TAGGED Vlan 2 and Vlan 3

Each Vlan can't communicate between the two switch, I think they're a problem in my vlan/port configuration?

WS-C3548-XL-EN / Setting Up VLAN On Old Switch

Aug 26, 2012

I have to admit I've never written my own Cisco configuration and I probably know just enough to break things. The last time I configured a Cisco was a few years ago, and the Wachovia people just told me what to type.

I have a Cisco WS-C3548-XL-EN and a Cisco WS-C3524-PWR-XL-EN "Inline Power" with default configurations and I want to setup VLANs. Basically, would this work?

SWITCH 1:Router on port 39, Wifi on Port 47, Uplink to 2nd switch's port 24 on port 48

conf t
interface VLAN10
no ip directed-broadcast
no ip route-cache


And then I would test that it works, if it does issue #write memory, and it it doesn't powercycle and try again?

Management VLAN Frames Blocked By Switch?

Sep 10, 2012

I'm having some problems with a D-Link switch. I believe it's filtering the management VLAN frames, which is really strange. If you look at the graph, you can see that the D-Link is connected to three switches by trunk links. I'll just use the numbers set in red on the graph to explain what's going on, it's simpler to see.So when I'm connected either to switch 4 or switch 5 (or the others on 5's level) I can use the management VLAN (ID = 1) to connect to all switches above number 3 (including number 3) but I can't get to switches numbers 1 and 2.The only way to connect to those switches is to either connect directly to one of their ports attributed to VLAN 1 or by connecting directly to switch 3. So that's why I concluded that switch 3 filters VLAN 1 frames. It's not switch 4 cause I can get from 5 to 3. But at 3, the frames stop.Also, this only happens for VLAN 1. We have some VoIP phones connected to switches 1 and 2 and their frames can communicate anywhere in the network.

Cisco :: VLAN Tagging At Access Port In Switch?

Sep 28, 2012

I'm Confused from the fact that Vlan tagging is done at access port and trunk port always gets tagged packets (untill its case of native vlan).But I still believe in other fact which says tagging happen only when a frame hit the trunk port which means trunk port gets untagged frame and tagging is not possible at access port.

Would like to know where actually this tagging happens ?

and also which command we can use to encapsulate 802.1q protocol to access port ? The way we do at trunk port is #switchport trunk encapsulation dot1q Is the above command applicable for access mode also?
