Routers / Switches :: Daisy Chain 3 Switches And Not Have Ip Conflict?
Jan 31, 2011
Is it possible to daisy chain 3 switches and not have ip conflict? I am running a public access network for a library. For certain library software I need for all workstations to see each other. I have 25 workstations in total and two separate management consoles. I have all workstations on two switches but one of the management consoles is on the third switch because when joined with the others it has an ip conflict. I need this console for the digital sender that is connected as well as to act as a server for go print software.
i am trying to daisy chain 2 pro-curve 1810g 8 port switches.i got the cable i need to connect them but i just want to know what kind of settings i have to change on the switches to have it run as best as it can.
I need to extend my wireless N network to increase the wireless reception power to a VIZIO Smart HDTV. I currently have a Linksys WRT310N router that is just barley being seen by the TV, Sometimes yes and sometimes not.I have just ordered a Linksys EA3500 Smart Wi-Fi Router. I want to set the EA3500 as the 1st (primary) router and CAT6 cable connect the WRT310N 50 ft closer to the HDTV.
I have got 3 wifi routers i want to daisy chain. Router 1 is main modem router, which is connected to 2 pcs and 2 wif routers (wired separately), both of these wifi routers have there own ip address and dchp turned off, so they work fine and broadcast wifi nicely. now what i want to do is connect another wifi router to one of these routers (not the main one) but what setting do i need? i tried to connect the 3rd wifi router with the same setting as per the other two ie diff ip and dchp off, but when i plugged it into the port of the second router it would not show as connected or get an internet connection. Its probably quite simple to sort out, but with me being a dimwit i am tering my air out. If i could not use a wifi router for this 3rd connection, is there any other way of putting an extra 4 ports on to my second stage router.
For my work I am looking to create wireless capabilities to remote locations. To do this we are using a standard modem/router that is connected to an Engenius (802.11b/g) wireless outdoor radio connected to a dish antenna. We are able to go to locations (3+km) and then with a corresponding receiving antenna (using LoS), receive the Internet and connect both to computers at the transmitting point as well as to the WWW. The problem exists is that we want to employ a series of routers at the receiving end that would be able to carry the transmission to a different location (relatively close), due to the fact that some of the locations do not have line of sight to the antennas. We are using Encore routers, model # ENHWI-N3. When we connect the radio's Ethernet into the routers WAN reciever, we can connect to the Internet with a computer. The problem exists is we want to pass that connection over to a second router (R2). This connection is done when the routers are on access points set to a WDS function with R1 having R2's mac address and vice versa. Both routers are set to channel 1. Even when the routers are seperated by distances >50m a computer plugged into R2 can see a computer plugged into R1. Files can be transferred between the 2 computers wirelessly at speed around 3 mbps. However computer 2 on R2 can not connect to the WWW. This router features a spot that lights up if it has Internet access and R1's is lit up but R2's is not. How do we transfer the Internet and not just a LAN from R1 to R2 so it can be accessed further away from the point of the radio and antenna equipment. This setup has also been used where R2 is hardwired to R3. At R3 we change the channel to 11, and then connect through that with mac addresses wirelessly to 4th router. If comp is in R4 and far away it can still access and file share from comp at R1.*edit the ip address for the routers exist all on 192.168.1.xxx If the 3rd number is different between routers would this make a difference?
I have sent up a wireless network in a large building using WAG120N Modem Router and four E1000 wireless routers set as access points. The E1000's have the DHCP switched off to enable roaming so the WAG120N takes care of all that.
I have a new Cisco 2960 S series switch with a basic configuration that needs to be uplinked or daisy chained to a Cisco 3750 switch. I am not getting any connectivity to the network with either a straight through or crossover cable. the port remains in amber but a 'show interface' indicates that the interface is up. I can manage the switch with a PC patched into any port on the switch with a static IP address. Must be something very simple that I am missing. Outlined below is the configuration.
I'm attempting to connect multiple computers, laptops and printers to the same LAN. I currently have the switch daisy chained to the modem. I'm having issues with conflicting IP addresses and wireless access. I think I have to create static IP addresses but don't know which nor how.The hardware I'm seeking to have on one LAN:
- Netgear CGD24G Cable Modem from Time Warner - Netgear GS116E un-managed switch - iMac OSX 10.8.x - Dell PC desktop, Windows 7 - Sony Vaio PC desktop, Windows XP - Dell PC desktop, Windows XP - Sony Vaio laptop, Windows 7 Pro - MacAir OSX 10.8.x - MacBook Pro OSX (not sure which OS version) - HP JetDirect 300x Print Serve (hooked up to HP LaserJet 2300) - Epson Artisan 835 - Netgear Universal Adapter for Home Entertainment (SAVB5004) - Netgear Powerline 500 Nano - Apple iPhones (4 of these) - Apple iPad
Several of these can work wirelessly, though I prefer wired whenever possible.I have been getting IP address conflict notices as well as the wireless signal not being received on some of the wireless capable devices, which seems to be random but it could be that I just don't know enough to recognize a pattern. I believe the devices are all set to automatic assignment of IP addresses.What is the correct way to daisy chain the cable modem and switch?What is the correct protocol for assignment of IP addresses in order to avoid IP conflict?Why does my wireless drop on some of the wireless-capable devices (such as the iMac, MacAir or Sony laptop)?
I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.
I have a question regarding two daisy chained routers. In the downstairs of my house we have our main internet connection that is hooked up to a router (router A). We also have an Xbox 360 hooked up to router A. Upstairs we have another router (router B) which is connected to router A. Connected to router B is a PC and another Xbox 360. Currently the downstairs Xbox cannot see the upstairs Xbox or PC. We used to have a network admin guy living in our house and the whole operation ran smoothly, however those days are long gone...
I live in a house with four other people so I need a lot of free ethernet ports.I currently have three routers daisy-chained together and I want to add a fourth, but I can't seem to.When I plug it up, pages refuse to load on computers connected to it. I read something about disabling DHCP, but I have two other routers chained to my primary and didn't need to do that. This one's branching off the main one though, instead of being at the end of the chain.I'm trying to hook up either the Linksys 4-port wired router or the 8-port one (I have both). I tried disabling DHCP on it and setting the IP thing to 192.168.2.1 instead of 192.168.1.1 and it worked for a few minutes, then nothing.I also tried that with the TRENDnet one and the same thing happened (had to reset that one to factory defaults).Is it possible to have two routers coming off another or does it need to be a proper chain? Why did I not have to disable DHCP on the others and they still work fine?
If your wireless indicator is flashing red when you discover the smurf, it can mean that someone has tried to logon with an incorrect password. this is not necessarily an attack, it could be someone you have allowed access too, who has forgotten the password? In this case entering the correct password will solve the problem.However putting your own MAC address into the filter will simply block your own machine.
If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
If I have two stackable switches were only one stackable switch has two uplinks one uplink goes to one core 6509 switch and the other uplink goes to the other 6509 core switch can a Layer 3 etherchannel be used if each uplink go to a different core switch, by the way hsrp is running between both switches and also can you give an example how data will be routed from the stackable switch through the ethernetchannel to one of the core switch accross the WAN to another core switch?
I have a stack of 6 switches and I want to add another over the gbit connector using fiber. I already connected but I can acces the network from the new switch. I don't have any issues on my Stack all resources are available Do I need to do some special setup or connection to enable this? Can be stacked like the others? I already usen the 2 stacking port can i Add another switch?
everything was all good, my brother went crazy and unplugged everything.it effects our house phone too, that could be the problem.i just dont know what wires went where. all the wires are the same color.but i know which is which. just again, dont know where.i would like to get it done before he gets home later on.
we just received 5 new SF200-48 Smart Switches for small business. I noticed only way I can configure them is by using the web gui. Is there a way to enable good old CLI?
now we have 2 switches: SF300-24..on one SF300-24 we config it at layer 3 mode with VLAN configuration same as following [code] And we use port 26 on 2 switches SF300-24 is trunk mode then we connect both SF300-24 switches.But on SF300-24 layer 2 cann't inderstand VLAN from Sf300-24 layer 3..How to config VLAN on 2 switches SF300-24 Layer 3 and SF300-24 layer 2?
I was looking for configuring QOS for two VLANS i have created. these will be for voice traffic vlan 22 and video traffic vlan23. i also have three other vlans for pc's, wireless devices and our cnc machines. we have 5 switches that are all SG30028P's with a single switch doing the intervlan routing (operating at layer 3). all of the switches are trunked back to the main switch and ive been through the guide written on how to do this on a single switch which i dont think is layer 3.
I'm replacing 2 3COM 4500 Swithes with the SG300-52 Cisco switch. We have 3 VLANs, 10, 20, 100. The switch is set for Layer 3 and I have setup DHCP relay. what settings i should set on the Cisco for the following setups:
I'm setting up an SNMP poller to retrieve the ARP table (ipNetToMediaPhysAddress) from my SF300 switches. I can retrieve the table from SF300-24P and SF300-48P switches running Firmware Version 1.0.0.27, but get garbage for the MAC address when retrieving that same table on the same model switches running Firmware Version 1.1.1.8. Is there an outstanding defect on this code level? How can I retrieve the table showing the IP address to MAC address mappings?
We have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each. Switch was connected to HQ Network as untagged VLAN 101. I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great. Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
I then Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.
does the SG300 switches can be used with Microsoft NLB in Multicast mode?I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?
We have a project in which we are using 34 Cisco SG200-18's each with a MGBLX1 (LC Single Mode Fiber) SFP mini-GBIC.All the fiber's come back to one building where we must "bridge" all 34 fiber connections. What hardware should be used to accomplish this? A L2 switch? For example, a 12 port SFP Switch with Fiber SFP's accepting the first 12 fiber connections, then other switch with SFP for the next 12 and so on, until there is a overall capacity of 36 and having patch cables between the 3 switches?
what cisco or non cisco hardware would work with these SF200-18's to accomplish this?
Any snmpset commands to add, modify and delete vlan table entries on SG300-10 switches? I checked url... however this information is apparently only valid for catalysts. The latest firmware is installed and the provided MIB files are used.
I looking to buy SGE 2010 swith, but I have some question:
1. Can I use 4 SFP ports and stack of two switches at the same time. 2. Is it possible to use for stacking ports other than 24, 48? 3. What is maximum possible number of ports to use for stacking (can I get more than 1Gb thruput).
I'm going to have several SG300-28P switches to setup. I'll need to create multiple vlans for data, voice, and wireless traffic. I have the following questions in setting up this configuration:
1) For managing the switches via IP, will LAN1 be the default management network? Should I create a seperate VLAN for managing the switches?
2) For uplinking the switches together, I plan to trunk a port to connect the switches together. What's the configuration on the trunk port to forward all vlans from one switch to another?
3) On some ports, I want to configure a trunk for two vlans (Data and Voice) where the phone has a pass through for PC. The phone supports tagging for the PC and the VoIP traffic. For example on port 10, would VLAN 100 and 300 be set to tagged?
