• SGE2010 switches, VLAN and a port blocked by spanning tree

  People,

  I have 2 groups of switch.

  SGE2010 2 with VLANS is defined as 10,20 and 30

  VLAN 10 is the management VLAN and it uplinks to our border router.

  VLAN 20 is the workstation VLAN, and all workstations are pointing to the switch as their default GW

  VLAN 30 is the ip phone VLANS, and all phones use this as a gateway.

  I have a GAP between the switches said, we have a few servers on the ip phone switch that must be accessed by the clients of the workstation and the unique link of 100 MB through the router probably won't be enough.

  If I understand correctly, because the switches have different networks on them, a simple shift will not work. I did create a gap and addresses on each side, but it does not appear in this mode, I can block vlan 10 transit to the LAG, with this block I'll end with a logic loop and spanning tree will block the uplinks or LAG itself.

  I have attached a picture with a diagram of our current put in place.

  Any help/advice would be much appreciated.

  John, the 802 standard. 1 initial q indicates there isn't only global tree covering weight independently of belonging to a vlan. It's why you run into problems. Cisco has developed PVST to run on circuits of the ISL. BPMH was originally defined as 802. 1s, which is a combination of 802. 1 q + RSTP. The 802. 1s were later modified to become part of the 802. 1 q.

  The person is incorrect, because they cite "because spanning tree is construction by vlan. They are incorrect, because you have to set the properties of tree cover to allow the spanning tree protocols by vlan. Small business switches do not support the owner Cisco PVST and PVST +. However, the SB switches support BPMH which is a standard of the IEEE.

  How works the BPMH, it's that you have called proceeding, i.e. each construction covering tree. Then you have the region, SB switches support only 1 region. The region maintains the instances. Basically how it works, you activate the EMU at the global level. Then, you specify the instance. As an example, the vlan 1 is instance 1. VLAN 2 is 2.  This will allow you to run 2 physical wires between switches vlan different without looping. If you use classic STP or RSTP, the least costly path will go to the State to block/cast who works as expected.

• interface vlan problems addin

  Hello

  I have a problem with my 8164F with 6.1.0.1 powerconnect version

  I create the vlan 643

  then I create an interface vlan

  interface vlan 643

  When I ping the ip address of the switch

  ping 172.24.64.2

• Implementing 802. 1 x in a by-switch-VLAN topology

  We have several switches 6509E access that currently have a single user VLANS by switch (for example access-switch1 users are to vlan 101, access-switch2 users on vlan 102 etc.).

  We want to implement 802. 1 x, so that users find themselves either on one vlan allowed or a vlan comments based on a successful authentication. However, we would like to keep the VLAN by switch topology so that users on switch1 go on vlan if authenticated 101 or comments vlan 201 If untrusted users on switch 2 would go on vlan 102 if authenticated or 202 if not authenticated etc..

  We are able to get this to work with a single vlan trust and only comments vlan, but they will have to extend over the entire network. Any body know if it is possible to allocate VLAN in 802. 1 x, according to what switch they authenticate to so that they are placed in the vlan OK for the switch?

  Thanks in advance.

  Hi Paul,.

  Dot1x RFC 3580 specifies that the tunnel Tunnel-private-Group-ID attribute is a string and is not specifically a number so that the solution to your problem can be done by entering the name of VLAN in the RADIUS server and configuring your access switches with the VLAN individual that you want to use on each VLAN one, but those who have the same function in all switches must have the same name that you entered in the server RADIUS exactly for example

  Switch1 - TECH 100 of VLAN, VLAN 150 COMMENTS

  SWITCH2 - VLAN 200 TECH, VLAN 250 COMMENTS

  Entries of RADIUS

  TECH

  COMMENTS

  So if a user with mac1 connects to switch1 or switch2 and is authenticated successfully the RADIUS server responds with the Tunnel-private-Group-ID = TECH instead of 100 or 200, regardless of the local number of VLAN on the switch if name is the name of the configuration of the switch, the switch will place it in the numbered right VLAN based on the name , hopefully eliminating the confusion of having to figure out how to the same user in a VLAN different numbered based on the access switch they connect at the time.

  Hope this helps

• SG300 voice vlan problem with UC520

  Salvation of the Forumers

  My problem statement:

  -Secretary referred to topology.png, this is how my network like structure look

  -the IP phone after startup can not connect, so it cannot download the XML of UC520 configuration file. problem switching suspects.

  -my configuration illustrated in topology.png and my config show vlan as the voice setting.png voice vlan

  -My requirement is switch SG300 unique switchport to carry data VLANs and vlan voice.

  -What is the mode of connection for voice siwth VLAN an IP phone + data must be set up? is it switchport voice vlan vvid switchport voice vlan dot1p, switchport voice vlan unidentified or vlan switchport voice no further action over requirement?

  Thank you

  Noel

  Christmas morning,

  Sorry for the late reply, things have been very hectic in here lately

  1. Why use trunk? the UC520 don't have voice vlan (vlan 20)

  Do you mean that data THAT VLAN is handled by another device? Again I would like to leave as a trunk in order to manage the CPU through the data VLAN. (Except for security or other reasons you would choose differently of course)

  2. the UC520 got CUE (voicemail), how should I design the uplink service for the main switch module?

  Nothing in particular needs to be done for this, CUE is processed and routed inside the UC520, the vlan (default ID = 90) CUE is used if you have another LANDMARK in the network

  1. I guess I did: swithcport the tag vlan vlan unlabelled 20, 10. is it ok for this setting?

  If the Vlan on the switch and the UC520 voice has been defined as VLAN 20 (default value = VLAN 100) it's perfect. Check if the CPU and the switch, the voice VLAN ID is set to 20.

  1 so if I have just the phone to vlan 20 (vlan voice), create the policy of network LLDP?

  If you are ready to configure the VLANS manually on the phone, you don't need politics LLDP, thats right.

  Politics LLDP is used to having phones automatically choose the VLAN you set, so you do not need to set it manually.

  I hope that answers your questions?

  Best regards

• The M6220 switch battery problem

  Hi all

  I have a stack of 4 switches M6220, I just updated the firmware to 5.1 that all is well in outside pass 1 member switch.  I have download the image the game disappears the switch to 2 that the reload fails and the image, now the auto update keeps cycling and switch 1 has been shaded in all settings.  He continues to say the update in the GUI.

  Can any ideas how I can force the update on who finally pass, it's very frustrating and time - anyone help?

  Thank you

  Eric

  After attempts to upgrade the firmware, is there something in the newspapers? # See logging. This could be a hardware problem with the switch. One last thing, I would try to apply the firmware through the XMODEM method. In the firmware download, there is a update guide. Page 19 of the updated guide details the steps of starting in the Advanced menu and applying the firmware through XMODEM. It will take some time to make it end.

  Keep us informed.

• ALT return switch application problem

  Hello

  I have problems with a claim on the toolbar to switch application Alt + return. I use a 8900 with v.5.0.0.592 device and the problem arises as well when the tests run in the emulator.

  The question is this. I have a few requirements of the carrier that makes us stop the sound application when the switch application bar pops up (after pressing alt + key at the same time):

  In previous firmwares (v4.6 who were the original for the 8900 device), when you perform this action, an event is initiated by the Application, so you can manage with the eventOccurred method (as the main class has an added GlobalEventListener).

  However, in this Application switch firmware don't lance not any event, and even no event is run when the application is in the background.

  You have a way to detect that the application Alt menu + back switch jumped upward?

  I also tried to detect this event in keyListener, but the KeyStatus method that recognizes the alt key does not detect let us when the levels of alt is held, just at the time when it has been activated at the same time.

  Thanks in advance.

  Kind regards

  Fabian

  Don't bother to intercept keys - there are three or four ways how a user can call the selector of the task (for example, ALT + ESC, press long the Application Switch menu item Menu key to name a few). Just follow standard practices proposed by previous posters and detect whether your application is no longer in the foreground (the events Application.activate/deactivate, Application.isForeground polling stations) or if your audio playback screen is hidden or invisible (Screen.onObscrured/onVisibilityChange events).

• Reset default switch SRW2008MP problems

  Hello

  I have a Linksys SRW2008MP that I am trying to reset to the factory settings. The guy who created it is most used in my business, and I do not know address IP to connect with a web browser. The switch doesn't have a reset on the back button. I follow the instructions in the Cisco's Web site which include connecting a cable to the console and use HyperTerminal to connect. I can connect to the switch and watch the start in HyperTerminal. However, when I get to the point to enter username and password (which should be "admin" and "", I just can't understand how do to the terminal emulator takes the input (a bit like pressing enter in a web browser).) According to the pictures on Cisco's Web site, there should be an Action-> Edit-> Execute option down below the connection, but I do not, then, perhaps, the switch must verify my credentials in arriving at this prompt?

  This is the first time in my life using HyperTerminal, and I think that's my problem. How can I get HyperTerminal to accept my input?

  I also tried to use TeraTerm, a different console cable and another computer.

  Any help on this is greatly appreciated.

  Thank you.

  Adam,

  When you use hyperterminal use the following settings:

  

  This should appear the prompt to connect the switch at this time.

• Language blackBerry Smartphones device switch Wizard problem

  Looks like the last switch device Wizard has the old problems. I tried to remove and reinstall and even a different machine. Each time, I get a totally different language. Is there an 'English' version only software Desktop or how can I fix this? TIA

  Hi and welcome to the forums!

  A few places to visit: Blackberry 101    tips & tricks

  I believe you are referring to BB Desktop Manager (not the device switch Wizard that is part of DM)

  I suggest the following steps (reboot insert a lot of restarting your PC... not only restarts, but at full power down). In addition, it is recommended that you are connected to the PC on an account with full administrator rights. In addition, Vista, use the option "Run As Administrator" for everything.

  Get a new RIM DTM software download:

  Download the software for the support of Blackberry  ((sélectionnez Télécharger BB Desktop Software-une fois la version choisie, anglais est 3e (sans gestionnaire de médias) and 4th (with the Media Manager) options down))

  * Choose the version which is more recent and (if any) compatible with your PIM (such as Outlook, if you are synchornizing via USB):

  KB12268 Applications supported by BlackBerry Desktop Manager to synchronize

  (3) install DTM on your PC

  (4) start the configuration Organizer:

• VMware switch Vlan configuration

  It is possible to switch the configuration that resembles a vmware

  interface GigabitEthernet0/4

  Description calculate node 1 eth1

  switchport trunk vlan 100 native

  switchport trunk encapsulation dot1q

  switchport trunk allowed vlan 100, 101 102

  switchport mode trunk

  spanning tree portfast trunk

  on the gigabitEthernet 0/4, I have a linux machine that needs these config.

  Thank you!

  Ah, very good. Sorry for my confusion!

  Yes, you can do it.

  interface GigabitEthernet0/4

  Understand and document how the switchport is connected to your ESXi host.  When you start, your ESXi host lists its physical network cards, called vmnic.  Enable CDP on your vSwitches (or LLDP if you use a vDS) so that you know how your ESXi host connects to the North.

  Description calculate node 1 eth1

  You cannot configure the descriptions on vSwitches Standard (you * can * configure them on a vDS). You can also, of course, port name groups however you like, with a few caveats.

  switchport trunk vlan 100 native

  The virtual switches VMware isn't exactly the notion of VLAN native.  If you want to leave the untagged packets ESXi host, you don't assign just one VLAN to that particular port group.

  
  

  switchport trunk encapsulation dot1q

  VMware only use 802. 1 q of marking.  There is no need to explicitly configure.  In addition, you can't.

  
  

  switchport trunk allowed vlan 100, 101 102

  Create a VLAN that you like on the ESXi hosts using the parameters of port group VLAN.  Don't forget not to set up a local VIRTUAL network for the port group that hosts the VLAN native.

  
  

  switchport mode trunk

  ESXi hosts accept several VLANs on a vmnic out of the box.  There is no need to configure.

  
  

  spanning tree portfast trunk

  This option isn't strictly for switching equipment, end-hosts as ESXi.  Your ports ESXi NIC will come as soon as possible.

• Windows 10 TP to switch 10 - problem with drivers

  Hello

  I managed to install Windows 10 TP on my Acer Switch 10 64 GB (x 1920 pixels).

  After struggling with the bootable USB installers (they ask for pilots from the start), I chose the online installation program. Downloaded all the files and compelted the installation.

  But after the installation of the touchscreen, Wifi, sound doesn't work at all.

  I tried to install the windows 8.1 drivers downloaded from the Acer site, but they do not have install.

  Could someone guide me on what to do?

  Thanks in advance!

  Not that you can do until the W10 approximates the output, I think we are about 6 months. The fate of the end of October for the three latest operating systems. You might be able to find the drivers beta on the website of the manufacturers for components, but official, working driver will not be released until W10 is finalized.

• 2 switch &amp; 2 VLANs

  Hi, I'm a new user and struggling for the next step... I have 2 switches SRW224G4P and SRW248G4P. I created VLAN1 and VLAN2 on both switches. In each single switch, VLAN work correctly. But how 2 switch can announce their ports VLAN1 and VLAN2 and work together? I mean how can ping VLAN1 SW1, SW2 VLAN1 ports? Should I just change the parameters of connection to the trunk and mode labeled for GB port? Thank you, Hasan
