• OK to mix 'of connection to the switch"and"close relay switch?

  Hi all

  I'm developing a test sequence using the card multiplexer 2527 to the track signals.  To configure the card, I use DAQmx switch functions.  In my application, I have a Subvi routine that imports the data from a spreadsheet Setup and run a loop for to set the configuration for each step (each iteration of the loop contains the channel for 2527 card information).  The topology is set on the first iteration, as well as the configuration of the path to the first string.

  My concern is this: I need to close the extra channels/relays without changing the topology or resetting the device.  In the first round, I use "connection to the switch" function to set the initial path, (ch0 to com0 for example).  Then in subsequent iterations of the loop, I use "Relay close switch" function to close the additional channels individually (for example k2).  In the end, when the measure is taken, both ch0 ch2 must be closed and routed to com0.  This implementation is so sure, or am I somehow to make the adjustments to the initial loop?

  I would like to test this with the hardware, but it is not yet available.

  Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer.

  Please notify.  Thank you.

  Hello GSinMN,

  It's OK to mix 'of connection to the switch"and"Close relay switch"If you understand what's happening below. "Switch Connect" connects two channels by closing a path of relay between the channels, then "Close relay switch" can be used to change the State of the individual relays. If you are not careful you can mess up your connection by activating / deactivating relays that are part of the route connecting your channels.

  "Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer."

  I would recommend the topology independent if you want to stick with connections to channels only. http://zone.NI.com/reference/en-XX/help/375472G-01/switch/2527_independent/

  Initial connection:

  CH0-> pcom0

  pcom0plus-> icom0plus

  pcom0minus-> icom0minus

  icom0-> com0

  In each future iteration just connect to the next to pcom0 channel (which will be indirectly connect it to com0):

  CH1-> pcom0

  CH2-> pcom0

• EA6500 only shows no device connected to the switch of working group 5 ports

  I just replaced a defective Linksys e4200 with an ea6500.  After assistance by phone, I got to the top and work, but only one computer on my LAN is not displayed.

  I connected an 8 port 10/100 switch Linksys my 4200, and my wife's computer was connected to that.   The computer displays the IP as 192.168.1.133 and it is connected to the internet with my router again.  But the ea6500 does not show a device with the ip address.  Instead, he shows what he calls a network with the IP 192.168.1.130 device.

  How can I see the devices connected to the switch 5 ports and determine which ip addresses, they have been assigned?

  I use a switch with my network with a router EA and it shows the devices correctly. Turn off the computer which does not appear in the list of devices and check to see if any device will appear as offline adter who. Remove from the list of devices, and then restart the router. Once the router is ready, open the page of the router again and turn on the computer and check if it will be detected correctly. I hope this helps.

  Edit: Check and make sure you have the latest firmware loaded. Otherwise, update the firmware and do a reset after the update of the firmware. Check your list of devices after that.

• How to connect two network switches Force10 S4810P

  Hello world

  We just bought two S4810P Force10 network switches and we want to install on two adjacent brackets. They will be used to interconnect computing and NAS storage, installed in two baskets serving mainly local connections.

  We intend to use ports QSFP + to connect the two switches, and I have two questions.

  1. hardware configuration: what are the best transceivers and cables to use in this case?

  2. configuration of the software: should we use stacking or virtual link trunking? the information I've read so far does not give me a definitive answer.

  Thank you very much in advance for your help!

  The server room is already has some inside wiring? If so it be a transceiver that will percolate pre-existing cables. There are also some direct attach cables ranging from 0.5 m to 50 m. Here is an example of a cable direct attach: http://dell.to/23huDl7

  the best course of action would be to contact your sales representative and let them know what your needs are. They can get you city for right connection hardware.

  the VLT and stack the two have the same goal of redundancy, but go about it in different methods with different warnings warning for both. In both scenarios, the redundancy is dependent on each device connection linking the two switches. If you do not do this, then it may be better to let the independent switches. Here is a good blog that compares the VLT and stacking.

• Connect the redundant switch

  Hello

  I have several Dell 2724 switches that I would like to set up redundantly.

  I joined two 2724 s with a trunk. I would now like to connect the access switch with one connection to each of the two switches to shared resources. One cable in switch1 everything works. Put the second cable switch2 and all breaks loose.

  Option1 = Switch2 (LAG)

  \       /

  Switch3

  Can someone tell me if it works and how?

  Thank you

  This kind of configuration can operate with switches that offer spanning tree or MLAG. But the 27xx series switches do not offer these features. With this type of installation, there is a loop that will cause a continual broadcast storm that will wreak havoc on the network. Your best form of redundancy will link redundancy switch, but you will not be able to get the redundancy of switch with 27xx switches.

  Switch1 SWITCH2

  \\       //

  Switch3

  Or

  Option1 = Switch2

  //

  Switch3

  Or

  Option1 = Switch2

• Using offsets to connect 4 2848 switches

  I have four switches 2848 PC I want to connect to the best way to deliver the good flow and link redundancy. There is no VLAN involved.

  I was not able to find a good setup for this example. From what I've seen, I think I want to use the offsets of 2 ports to connect the 4 switches thus:

  SW1-SW2 >

  SW2-SW3 >

  SW3-> SW4

  SW4-> SW1

  I saw that it would be preferable to set the cost of path higher for the SW4-> LAG SW1 ports to avoid a loop.

  But beyond that, I have no idea how set up correctly with regard to the settings in the user interface. Does anyone have an experience with which could provide me with some guidance on how to configure the GAL on each switch?

  Thank you very much in advance!

  Your plan sounds great. It's a logical layout of the ports.

• connect the m6220 switches stacked to existing Lan infrastructure

  I need to connect two powerconnect M6220 to LAN infrastructure existing.

  The switch of two are configured in the stack.

  Which is the best way to uplink the new switch to the other two powerconnect 5548.

  The old switch are not stacked and bound together by two 10GB Ethernet cable (one of the links is disabled).

  I need to implement the network tolerant to failures, maybe I need to configure the tree covering weight on the two links of 10 GB.

  I use Spanning tree to configure the uplink between the old and the new, too?

  Is there a better alternative? There is another way to prevent the loop network?

  Thanks, Francesco

  You have a few options.

  1. you can simply connect the cables between the M6220 switch stack and the 5548.  Set up a trunk connection which allows for VLAN needed overall.  Tree covering weight until it is enabled on the switch and not off on specific ports connecting the default switches prevent loops and allow the most profitable link to be active, leaving the second connection as an alternative link in a blocking state.

  2. you can configure LAG (aggregation of links).  This is where you configure the individual physical ports in a virtual port channel.  This indicates a covering tree to treat multiple physical ports as a single link aggregated to the other switch.  You will need to have the port at each end of the connection channel mapping. (On each switch).  This allows the same speed but more flow.  To move traffic more.

  You must watch your switching configurations and go through them carefully.

  Just looking at them, I can see that EIGRP configurations are wrong.

  On each switch, you should have statements of network for connected networks, not for networks that are not directly connected.

  If you go through them again and refer to your diagram, you should be able to see that you have set up statements of network under EIGRP for networks that are connected to other switches.

  This is why EIGRP is not coming.

• Connect with independent switches vSwitch

  Hi all

  I am a newbie in VMWare and really not had in networking. Need your suggestion kindly for our VM infrastructure plan.

  Here's what I have (or will have):

  I create a small cluser (2 ESX, each with 6 NIC host). There are 2 stacked Cisco 3750 and stacked 2 4524GT Nortel on our farm in GE switch. Up to now, we have 6 virtual machines, but we intend to put all the servers the VM infrastructure.

  That was my previous plan:

  I did some research in the documents of VMWare and BBS.  I plan to ESX hosts connected to Cisco units, their link to GE in 2 units of the evening. Configure NETWORK adapters, port channels, load balancing, etc...

  An incident has changed my mind. A month before our network, group support updated nortel switches firmware. It's a nightmare. The Nortels 2 were dead after the upgrade. Had to pass all connections to the server of Nortel to Cisco and roll after that the call of Nortel has been set.

  My question:

  So let's say that sometimes the stackable switches will be dead together. Yes, I can connect an ESX with Cisco and another with Nortel. When stacked Cisco or Nortel is dead, we have yet another host working with switches lived. But I can connect an ESX with Cisco and Nortel? It seems more stable, isn't she?

  For example, I intend to use the 4 NICs for production and other for SC and VMkernel network interface cards. The production of 4 network cards are rising in a vSwtich. Failover and load balancing works when I connect nic0 / nic1 with Cisco and nic2 / nic3 with Nortel?

  My recommendation:

  Configure NETWORK adapters, port channels, load balancing, etc...

  Forget it. No team, no port channel. Just configure the uplink as junction ports ports and set the VLAN on the virtual port groups. VMware ESX (i) (with standard vSwitches) performs Round Robin load balancing based on the original default virtual port code, which is sufficient in most cases. With dvSwitches, you also have an option to configure NIC database load. In both cases you can use ports on all physical switches without having to think about making active configurations / standby at all.

  On the beat of the heart. Usually, I connect the Service Console to a vSwitch with 2 physical uplinks, each on a different network card and everyone to another physical having redundancy switch. What I actually do is to put the Service Console and VMotion that vSwitch and configure groups of ports for active / standby to ensure that each of them uses a dedicated NETWORK adapter unless there is a network outage.

  You must also consider switching to (installable) ESXi as ESX will be greater in the future. If you do not need to install agents on hosts etc, the only change will be that you will not have a "Service Console" more. For communication and management, you will have a «VMKernel network management» instad

• Try using four nic as an external switch ports

  Hello

  I have a quad port gigabit nic in my esx Server I want to use it as a 'switch '.  that is, I have a vSwitch with all my VM on it, and I have included 5 NICs in there.  One is an internal NETWORK interface that works very well, and the other 4 are quad port PCI-E adapter.  For some reason when I plug a physical computer into one of these 4 ports, I'm not able to get a network connection and cannot communicate with the virtual machine.

  Is there something I'm missing here?

  Thank you

  Hi Dontinou,

  If you want to connect physical machines directly to external ports? It is not how ESX should work but why not, special purpose...

  First of all, you need to use crossover cables (or have the network card can detect direct connections).

  Then, you must have a group of port by physical map (or a vSwitch) because when you join a virtual computer in a vSwitch, it uses all the physical ports but only one. Then configure each port group to use an identified uplink and attach each virtual NETWORK adapter to a group of different ports. Finally, give a different IP address to each vNic.

  The problem with this design is that you need to configure each physical machine the IP addresses of the virtual machine they want to contact on they are connected to a specified card... It's not easy. And physical machines will not be able to contact each other, unless you install a router within the ESX VM.

  You'd better buy a small switch.

  Good luck.

• LAN N450 connection through a switch problem

  I replaced my router from Time Warner Ubee with a Netgear N450. I have 2 desktop computers and TV and PS3 in my basement that is connected to a Netgear GS108 switch 8 gigabit ports. Everything worked fine until I swapped the router. All my wireless devices work and the office in our head office that is connected directly to the N450 work. A desktop running Win XP Pro, the other works under Win 7. I don't get "LAN was not a valid IP configuration errors. I rebooted everything, turn off DHCP and tried to manually enter the IP information, power off the pc from the wall outlet, etc. and spent several hours on researching this issue. Any ideas would be useful.

  Problem solved. I brought the Win 7 PC upstairs and connected directly to the router. The PC immediately recognised and connected to my home network. Then, in order to eliminate potential problems with the switch itself or wiring, I brought the upstairs switch and connected between the router and the PC Win 7. Same results as above - connected to the network home and Internet. Took everything back down and voila - both PC is now successfully connected to the host and the internet using DHCP network automatically. Not sure why it worked. I went through this simple process to diagnose potential hardware issues.

• Connection with a switch EZXS55W or a second router WRT54G to my router network WTR300N home?

  I have a home office in my basement with my computer connected to a lan of my WRT300N router that is set up on the first floor and networking with three additional computers to the floor as well. I want to add 2 additional computers in my basement and wireless is not a good set upward because the signal strength is very low. I have great reception on the floor and even on the second floor where my children are connected from their rooms. My question is: I have an older WRT54G Router I use is more and want to know if I can connect it to my WRT300N using the lan line ran down in the basement which is connected to one of the Ethernet ports of the WRT300N? If so, how the connection and set up the second router? Also, I can use Ethernet cables to connect my three computers to the second router or what I need to use the wireless of the second router? I was looking at the switch EZXS55W at the Wal-Mart local and thought that was my answer, but after a search through all the answers of the basis of knowledge here, I'm confused on the approach to take and which one would be the best game for me. Here, any help would be great!

  With the EZX you extended your wired LAN. You can still use the WRT54G to add another point for other cable ports and wireless access. Just do these 4 steps as stated in my previous post.

  You can connect the WRT54G the WRT300N or the EZX. Basically, it's all the same. You don't have to turn off the switch before you connect a device.

  If you want to use the additional wireless WRT54G, you can try to set up a roaming wireless network. Implement the WRT with identical settings as on the WRT300N wireless, i.e. identical SSID and wireless security the same (preferably WPA2) personal with a good password. Do not turn off the SSID broadcast on either WRT. Only the allocation of channels should be different at a time to avoid any interference. Now the devices should be able to move from one access point to another without losing the network connection.

  However, if you perform this configuration test carefully. I don't know how it works if you have a N Router and a G. If this does not work, use different SSID on both. You can then choose which SSID to connect to on the client.

• Connect together two switches SRW 2024

  I did some research on this and I'm getting mixed results.  I have 5 Configuration of VLAN, not including the native VLAN 1.  Vlan1 has 1 as untaggged and together the trunk port.  Him is excluded.  VLAN 100 has unidentified port defined on trunk and labeled 1 and 9-12.  VLAN 200 has 1 trunk port and labeled and 2-6 unidentified.  VLAN500 port 1 tag/trunk and 14-20 untagged ports.  VLAN 600 has a port like the trunk but excluded and 21-24 as not tagged. VLAN 700 has port 1 as marked and 7 and 8 as not tagged.  I didn't buy an exact duplicate of the switch, another srw2024 and I want to connect to this existing switch.  Could someone tell me how I can do cela two ways: a way to broaden the VLAN to the second switch and the other with just to add the second switch and be able to create new VIRTUAL networks?  Any help is greatly appreciated!  Thank you =)

  You must create all the VLANS on switches where traffic of this VLAN may occur, either because there is a device connected to VLAN access mode, either because the traffic must travel through the switch. So, in your case, if you create a new VLAN on the second switch probably want to create the same VLAN on the first switch as well and add this new VLAN for the trunk between the first and the second switch port (i.e. make new Member tagged VLAN on the trunk of the ports at both ends).

  Of course, if the first SRW not connected to any other router VIRTUAL local area network or the Internet (e.g. you have a completely closed environment) and that you do not need a VLAN special on one of the switches, there is no need to add the VLAN on the switch or trunk ports. For example, if all the VLAN 100 devices are connected only to the second switch and none of these talks of devices outside, simply configure the VLAN 100 on the second switch because VLAN 100 traffic must never travel to SRW given that there is no device in VLAN 100.

  It is possible, however, generally for clearer network design and a greater flexibility in your facility, I recommend you to run all the VLAN through all switches so that later, when you want to add a device to VLAN 100 on the first switch you would only configure the port rather than begin to implement a new VIRTUAL LAN and configure trunk ports...

  You can't the front switch the router because it wouldn't give the DHCP issued IP address of this way. The indicated above guy in the correct way to do it.
