• Problem with switch Cisco SG300

  Hi guys,.

  I have a problem with switch Cisco SG300-20. After the failure of the switch boots in a kind of mode. It requires

  MAC address and serial number to be entered manually for the device. I tried to find information on this mode, but without success.

  My question is: what is this mode and how to make the start switch in this mode?

  How can I turn on the switch in this mode on purpose if it happens again and I enter the wrong information by accident.

  Thank you

  Hi Aegx, this is a rare case where the switch basically forget his identity. Although the switch is recoverable, it is recommended the switch RMA.

  If you are certain that you have neither taken under warranty, all the information that is asked is on the bottom of the switch sticker. If the thumbnail is is not present you wouldn't able to do this is correct.

  In addition, if you make a typographical error, the switch will have undesirable failures that are permanent, such as the inability to update software.

• Switch Cisco Nexus 6004 removes more than 300 bytes IP packets

  Hi all

  We have a circuit of wave level 3 10 G running between two switches Cisco Nexus 6004. The circuit came online between our two data centers (in the same city) without problem.

  When attempting to ping to the remote-end 10G interface, it works very well with packets of 64 bytes. CDP is enabled and that we see the CDP information remote switch. However, if we increase the size of the ping to more than 300 bytes packets, we lose 1 in every 20.

  We settings MTU verifed, type of cable of 10G and duplex settings.

  Level 3A tested clean and we will move forward with more testing.

  Any ideas on the problem? We feel the carrier out and end to test with their testers. But so far, the circuit's own test. I was not sure if it is something related to Cisco. I am at a loss at the moment.

  Thank you.

  Hi Mike,.

  There is nothing wrong with your switches or circuit.  NEXUS devices have a default COPP on the control plan that limit the size and the amount of traffic that must be the CPU process.

• Switch Cisco 2960/3560 = > recovery password and default settings with the button Mode

  Hi Experts,

  I have some confusion with the button Mode with cisco 2960/3560 switches.

  I read on many forums and articles, but where things are not clear.

  a place given 3 seconds and somewhere is given 7 or 10 seconds.

  Qus1), what is the exact time to press/hold Mode button to perform two following tasks:

  A. password recovery (according to my knowledge 3 sec) good or bad?

  Configuration of the switch (start + run) would be safe

  After the recovery of password? Yes or no

  B. factory default (according to my knowledge 10 dry) good or bad?

  I'm afraid, because if I press mode button more than 3 seconds, then

  It will delete any configuration of cisco switch. Yes or no

  Qus2) I want to recover the catalyst 2960/3560 switch password without

  Start/run configuration to lose. That is my main concern.

  Please tell me how to do this, what will be the time keeping Mode buttom

  in a few seconds?

  Qus3) which means this line

  "If the password recovery mechanism is disabled in switch

  then you will lose all the config.

• HP Pavilion DV6 3122TX: updated the BIOS F.29 don't switch HP Pavilion DV6 3122TX Ati graphics card

  Hello

  I have HP Pavilion DV6 3122TX and recently I was updating my drivers and software from the HP Web site for my laptop. Everything was done smoothly. As I updated my BIOS, I noticed that I was not able to switch between ATI Radeon 5650 and Intel HD Graphics, then I was also shocked that he wasn't showing a charger plugged into icon too. Although the battery was charging but didn't show any icon for it. I am running Windows 7. After a few days, my battery was went wrong and was not in charge. I bought the new battery from HP Store for my laptop, and then after a few days now he is dying too. My computer laptop suddenly stops on about 30% of battery remaining and battery does not charge. I arranged another charger and plugged, but once more. I gave the laptop to the service center local and got NO from them as well. They couldn't find the problem. After a lot of research and reading messages HP, I finally understood that it was the problem with the BIOS Update and Windows 7. So, out of curiosity, I installed Linux RedHat 6 on windows 7 and everything was OK. But I am a graphic designer for Linux is not a good choice for me. I want to just restore my BIOS in its original version of the default BIOS. Please kindly help me to get my original BIOS. I tried everything on my hand. I also ask HP to the original versions of the drivers like BIOS on its Internet site. My laptop is dying. Please, Experts, I need your kind assisstence. Thanks in advance

  @AbdulRaheem25

  Create the key USB HP Diagnostics of material 3-in-1 PC and boot to it.

  If you updated the BIOS from the old version will still be in a folder of your operating system. Use the method I proposed to get it back.

  If you are unable to read the instructions on the web page of Diagnostics of material for the HP PC, then I suggest that you pay someone to do it and create the flash drive for you.

• SWITCH Cisco/Linksys SLM224G: Problem with the VLAN

  Hello!

  I'm trying to set up a VLAN in my baskets. I have some knowledge about VLANs, but I still can not configure in my path.

  My situation:

  I have PC that contains two virtual machines, which works as a router between three networks: LAN, WAN, LAN2. It's a bit complicated, but I'll try to draw:

                                                   |-------------||----------------------------|                   |           e1|-to-eth1-VM2-----WAN|VirtualMachine 1        eth0|---trunk-VLAN1&2---|g1         e2|-to-eth0-VM2-----LAN2|eth0=VLAN1 eth1=VLAN2       |                   |           e3|-to-eth0-VM2-----LAN2 etc.|                         PC |                   |   SWITCH  e4||VirtualMachine 2            |                   |           e5|-to-eth1-VM1---wire-to-LAN2|eth0=VLAN3 eth1=VLAN4   eth1|---trunk-VLAN3&4---|g2         e6|-to-eth0-VM1-----LAN1|----------------------------|                   |           e7|-to-eth0-VM1-----LAN1 etc.                                                 |-------------|
  
  gX = Gigabit portseX = 100Mbit portsVMX = Virtual machine numberwire-to = patch-cord connection between ports on the switch
  
  Schema of routing and logical visibility:
  
  LAN1---VM1-----VM2---WAN              |LAN2----------|
  

  Important note is that LAN1 and LAN2 must be separated (visible only through routers). WAN must be visible through VM2 to LAN2 and through by VM1 and VM2 to LAN1. It seems easy, but VLAN that I did on this passage seems doesn't work.

  I do it like this:

  Step 1: Management of VLANS / create a VLAN...

  Creation of VLANS 1, 2, 3, 4 (numbers meters right now - I have now this number 1 is restricted to the switch).

  Step 2: Management of VLAN / Port to VLAN...

  Setting up VLAN1 with ports g1, e5 (the two labelled or not identified?-I have not seen any difference)

  Implementation VLAN2 with ports g1, e6, e7, etc...

  Implementation VLAN3 with ports g2, e2, e3, etc...

  Setting up VLAN4 with g2, e1 ports

  Step 3: Management of VLAN / Port setting...

  Implementation of ports e1 to PVID4 (chassis type = all I guess, but with "capture filter"?)

  Setting up port e2 at PVID3

  Setting up port PVID3 e3

  etc...

  Setting up port e5 for PVID1

  Setting up port e6 at PVID2

  Setting up port e7 for PVID2

  etc...

  Thus, on this configuration and that the switch it does not work for me

  I know that the switch is to see Mac since VLAN which is carried out by PC, because when I arrive in "Admin / dynamic address" I see pimps on the correct ports, with good VLAN ID. So the problem is to transmit a VLAN for their ports, then clear frames of ID and let the packets to go (and return: clear packages, add the VLAN ID and send to their Gigabit ports).

  Show the configuration is one of the many I tried :/ but I think this one is the best.

  Or maybe I don't know VLAN as I think and this scheme is impossible? Please tell me.

• connection of switches cisco and hp with gbic

  I have a new Cisco 2960 x and an existing HP 2910al. I am OK with the set up, I have the hp interface and Cisco all the time with copper but this is the first that I had with fiber. I know that Cisco switch will a Cisco gbic (can move only with service not taken into charge-transmitter/receiver) and HP will want a Gbic hp (new Hp operating system only works with HP Gbic).

  So here's the question, Cisco Gbic and Hp Gbic of interconnection? I guess Yes, but want to ask before you buy and know that they don't.

  As long as they are of the same wavelength (like SR to LR to LR or SR) Yes they do.

• Launch by programming a sequence file don't switch for execution in the user interface

  TestStand 4.2

  LabVIEW 2009

  Windows Vista Business 32-bit

  My movie file uses a SequenceFileLoad reminder to start his own execution automatically by using the entry point TestUUTs. This is accomplished by calling the Engine.NewExecution method. The problem I have is that my custom LabVIEW user interface does not switch to the view of execution when execution begins. If I manually start the execution using the TestUUTs key, the point of view of execution is displayed.

  In my interface user, changing the display of the sequence at the sight of the execution is done in the event callback, DisplayExecution, and the StartExecution event reminder. I also tried the ExecutionChanged event reminder, but realized that it did not apply in this case. The complex UI that comes with TestStand works correctly and, as far as I know, I use the same event reminders to manage change in my user interface.

  Any ideas? What Miss me?

  Thank you

  Toby

  CLD, CTD

  I realized what was going on. I was to switch it on the SequenceView using the ExecutionClosed callback, but was not checking the number of executions that have been opened. Opening my file of sequence autolaunching would open two executions, one to open the file and the actual execution of the file. As soon as the file has been opened, the first run was closing my UI to return to the display of the trigger sequence. Execution else had already begun the execution of the sequence file so he would continue to run in view of the execution, but I didn't see it.

  I now use ApplicationManager.Executions.Count and only to switch back to the SequenceView if it was not open execution.

• Acer aspire switch 10 no boot device

  Hello, I am working on an Acer Aspire Switch 10 2 in 1 (there so no usb port and no cd drive) when I turn it on it flashes Acer logo for a second and then jump to "No boot device" with an image of a hard drive and a magnifying glass. This was not the case before. I could get for the recovery and trying, but it did not work. Now it seems that when I go in the settings of UEFI, boot order options have nothing other than IPV4 and peripheral USB for possible boot options.

  On information in the BIOS, you can find any reference to the members of the SSD?

  If this isn't the case, it is probably a hardware failure.

• LGS308 Port Trunking Switch Cisco 3650

  I have a Cisco 3650 switch I need to connect my Linksys LGS308 again. I have the port trunking install everything on the side of Cisco, however, I'm not very familiar with trunking on the side of Linksys. What should the configuration looks like on the side of Linksys? Currently, I installed port no. 1 port trunking, and all VLAN belong them to this port. Once I have save the configuration, I can access is no longer the switch. Any ideas?

  The series of LGS Linksys has the same methodology VLAN that Cisco switches series SG.

  Which means a Port marked as port VLAN Trunk will be no marked member (PVID) of a single VLAN and can have several VLAN Tag assigned.

  Example:

  Cisco 3650: Port 1 set as a VLAN Trunk; PVID = 1 and tag VLAN 2,3,4

  LGS308: Port 1 set as a VLAN Trunk; PVID = 1 and tag VLAN 2,3,4; Management VLAN = 1,

• Cannot connect the switch Cisco Cisco SG300 - 28 p spend and traffic through VLANS

  Try to connect the Cisco SG300 - 28 p switch to another switch and proceed 2 VLANS between them.  Not doing any circuit.  If I connect a computer to the port on the SG300 - 28 p I can access the VLAN 2 and take a DHCP address. However, when I connect to another switch on the port and connect it to a port on another switch secondary I am unable to access VLAN 2 and pull an IP address.  I checked that the works of secondary switch (WS-C3560G-48PS-S) connected to the other 3500 s, but not this latest SG300 - 28 p.  Here's the configuration for both, I'm leaving areas that shouldn't matter and add if necessary.  Try to connect the SG300 - 28 p Port 26-WS-C3560 Port 1 port.  Once again, if I connect a computer to port 26 on the SG300 - 28 p I access the VLAN 2 as expected, but not when I connect to channel 2 on the secondary switch.

  Hello

  Yes, STP is the problem here. As you can see on your release of the Cisco 3500 switch, port Gi0/1 is BKN (The FEW is a shortened form of "Broken").

  This is caused by an incompatibility of versions PLEASE used between the two switches. Small businesses (including series SG300) switches are use legacy STP or Rapid STP (your case), but uses templates to business (such as catalyst 3500) PVST + (each VLAN spanning tree version of STP).

  Two versions between group of switches are compatible only under certain conditions. Important condition is that the two switchports needs to use a VLAN 1, vlan access/native and not any other number VLAN.

  It is to make your communication work, you must:

  • disable the STP at least 3500 Cisco switch:
    • on overall global (Switch (config) # no vlan spanning tree 2)
    • or by the base interface (switch(config-if) # no vlan spanning tree 2)
  • change the configuration of your connection between two switches by following the path:
    • change the switchport trunk (trunk switchport mode) mode
    • do 1 VLAN as native vlan (vlan switchport trunk native 1)
    • Towing VLAN 2 as vlan tagged on that Stump (switchport trunk allow vlan add 2)

• Switches Cisco stackable, 500 and the consolidation of NETWORK cards

  Am looking using the stacking and NIC teaming to create redunancy for user access to servers. What I think is becoming 2 switches SG500-28 and set them up in a stack which appears as a logical switch. Now on the servers I have re 2 network cards to be a team so that they appear as a logical interface 1, perferably in an active/active configuration using LACP. In this team NIC take 1 member of the team to either switch B, so that each Member of the team is on separate switches.

  Givent the scenario:

  (1) who will work with the switches of the 500 series? The switches is that their price point is perfect for my client.

  (2) in addition, the connection of the battery will be there also needs to be a GAP between the switches or the connection of the battery is also data traffic?

  Hi Robert,.

  (1) I don't see any reason that this would not work as desired. There are the requirements by doing a SHIFT but being on the same physical switch isn't a.

  (2) with the switch of SG500 line, you have a few options for up/down the link between the switches to the battery, it depends on the model. Each of them supports 1 G up and down links with copper. The switches are then divided and support 5G or 10G mini-gbic down links. There is not currently an options trolling battery links.

  Let me know if that answers your questions!
