L2VPN ASR9k circuit of attachment in the switch (not marked frame)

Hi guys,.

I am trying to look at the best solution for the creation of a Pseudo-filaires on an ASR9k and extend the accessory circuit in one or the other 6500 or Nexus 6001 switch.

The circuit of the attachment must not be tagged, so that the customer can push some VLAN they want on their executives. The scenario I'm looking at would imply a 6001 Nexus or 6500 who sat below the PE and provide the physical presentation of the customer.

I thought a VCA using Dot1q tunnel with each client associated with a tag on the EP and the S switch, but haven't tested it. Another way would be to use a bridge domain to link two interfaces together on the EP, but that would still potentially require Q-in-Q isolate each customer and to enable each client to push some C-tags they want on executives.

Any help on this would be much appreciated!

Steve

the best way to me and I've tested this, would be:

Customer--(dot1q)--QinQ/tunnel---6500---(AC)---(dot1q-SVLAN)ASR9k(MPLS)

This way you can provide a vlan transparency without having to return to service each client.

  • virtual flash resources management is unable to recognize the SSD not (marked as ssd)

    Hi all

    As far as I KNOW, the SSDS should be visible as "local". You can run the command.esxcli storage core device list -d   and check if the device is showing as local ssd

  • Lesson 2-1: the switch Debouncing.

    Hello!

    I have a question around the use of the switch on a GPIO PIN.

    When I worked with Arduino Uno, I used to refer to this tutorial to debounce switch. The following is an excerpt from the tutorial (underlining).

    This example shows how to debounce a entry, which means check twice in a short period of time to ensure that she is certainly in a hurry. Without debouncing, by pressing the button once can appear as several presses code. Uses the millis() function to keep track of the time when the button is pressed.

    I'm curious as to why it has not taken into account in this lesson. Conversely, suppose, I want to keep the LED lit until you press. How would one implement?

    Kind regards

    Hi nanou -.

    Curious - where do you see the content of 2-1 lesson?  I haven't posted the content for the course may yet - it's path of March?

    First of all, the Raspberry Pi has integrated circuits to eliminate some of the rebound, and so I have not really known to bounce with the switches that we use in the course. That said, take a look at this post for ideas on how to do it in software.

    Conversely, suppose, I want to keep the LED lit until you press. How would one implement?

    Set the PIN for LED raw and on the spindle attached to the switch, look for a transition from State of low to high (TRIGGER_RISING_EDGE). Add a PinListener to the swichpin and when the button is pressed, you will get an event and valueChanged is called. Set the low LED in this method.

    Does that help?

  • Using the switch GS105E

    I have a co cable. as provider and modem cable. Question is can I use the switch above directly attached to the cable modem and wired to 2 computers and a smart TV, or do I need a router as an intermediary between the switch and modem?

    Hi again redrocktom,

    You can use the switch if this is the case, but there is still a bit of a problem. Once a unit acquired the IP address from the modem, it will let you not get the other devices to the internet because they don't have an available IP address more. To fix, you must unplug the first device that has acquired the intellectual property and restart the switch. So, it's the kind of hassle.

    Thank you

  • put Airport Express before or after the switch?

    Believing that it is preferable to wire as much of my LAN House as possible, I ran ethernet in all the House of my office (where desktop computer, printer and modem/router DSL reside) in my living room (Roku, Apple TV, etc. where).  The living room is also where wireless laptops, iPads, generally used smartphones.   So I'll have a (Netgear GS205) switch in the living room and an Airport Express station.  It doesn't matter if readers (of the office) ethernet switch, which results in turn the Roku, ATV and Airport Express?  Or better to attach the ethernet to EI and continue the switch port LAN on EI?

    Any reason, that I should consider to put the modem/router in the lounge and the switch in the Office?

    Netgear GS205 is a Gigabit Ethernet switch, so it will load 1 000 Mbit/s connections.  The AirPort Express has only 100 Mbit/s Ethernet ports, so if you plug the Ethernet cable from the Office to the AirPort Express, and then connect the switch to the LAN port on the Express, the ability of the switch 1 000 Mbit speed <-->/ s will move to 100 Mbit / s for all connected devices.

    All wireless on the Express will also drop up to 100 Mbps.  So, you might think that you have a 300 Mbps wireless connection, but this connection will drop up to 100 Mbit/s, through the Express.

    Not too exciting, but not a killer in the face if all devices that need to connect to the switch are only 100 Mbps devices compatible.

    It would be better wiring practice to connect the Ethernet feed from the office to the Gigabit Ethernet switch and then connect devices to the switch. Here, I guess that the Ethernet feed office is actually Gigabit Ethernet to 1 000 Mbit/s.  1 000 Mbps or Gigabit Ethernet ports should use any modem/router of good quality.

    If the modem/router that feeds the switch is only 100 Mbit/s capable, then you can connect things like what you want since the maximum speed on the network will never be above 100 Mbps in any case... and the Gigabit Ethernet switch will work on only 10% of its capacity.

  • By default the switch button?

    Can we by the use of 'property' or 'Node to invoke' change the default value of a push button?  I'm trying to create a switch that works as a button with mechanical properties "engaged when pressed ', but the output of" Switched when pressed.

    I searched here without any result, but maybe I'm looking with the wrong key words...

    I have attached a VI that simulates what I'm working with right now... order 1 and 2 control simulating a sequence of control that I have who controls a valve... Control 1 opens the valve and 2 control closes the tap.  The counter in the Structure box should give me a way to sense "the hunt", which is basically when the valve moves too fast so he pulls past the set point and reversal, once he does so many times, in this case 5 times, a 'Real' signal is transmitted to the Signal LED and I am eager to make , it is consider as True and have this 'click' switch so my signals is redirected, and my current thinking is to have a flat structure sequence in a structure of event in order to use a node called "Reint to Default" and then change the value by default if effectivly flipping the switch back and forth. Once I get this figured out part so I'll be shortening the time the signal is sent to the valve.

    I have built this thing 20 different ways, but still can't make it fit... the 'real' counter is always just a single blip as the while loop runs.  Anyone here have any idea or suggestions on how to do.  All that I am really keen is the equivalent of a single pushbutton switch... push once and it's on, push another and it's off.   .. single .so True and it is, and then only real and it's off.  I don't know, maybe I just do it more difficult that it really is.

    Thank you!

    Chad

    Fair value the mechanical action Switched pressed instead of locking.  Then use local variables to switch state.  In other words, when you get the status of overtravel, write a fake to the local variable.  Switch when Pressed, it's like a push button switch.  Click once and it is enabled, click it again and it is off.  Just look at how you use local variables, so you do not have a race condition.

  • Need to set the switch to the user event

    I am creating the simple thing by closing the switch as in image2 light bulb can I achieve using adobe?

    The image1 is real state and when I close it (on user event) the switch, the switch status should change and bulb should light up.

    When there are still once a user switch event must be like the image1.

    Image1Image2.JPGImage2Image1.JPG

    Yes, you can create this effect using Flash.  You can create two different frameworks, one showing the open circuit and the other showing the closed circuit with the light bulb on the schema within a movieclip.  Some event you intend to tell the movieclip to change images based on any framework is now.

    It was an approach, but there is a varoiety of ways to do this.

  • Installing TB31.3.0 on a W8.1 workstation; I want to delete the messages on the user agent of TB, but prevent deletion on the server. Where is the switch? When to install

    Hello!

    I have already installed a TB user agent on my workstation 'primary': I can create, read, and DELETE messages ON the workstation and the server.
    I want now to install a user of TB on a "secondary" workstation agent, where I can create, read and DELETE messages on the workstation. But I don't want the secondary workstation to delete messages on the server. (In short: I want that the function "delete" ONLY allowed to my primary workstation).
    Is this possible? Where is the switch ON / OFF? (For example, this feature is available on the agent on my WindowsPhone).
    When I install it?

    Thanks for your support!

    Using Thunderbird on your second workstation - the only option would be to create a Pop email account
    so before you download anything, you must configure the account settings to "leave a copy on the server.

    Tools > account settings > account for Pop mail server settings.
    or
    Menu icon > Options > account settings > server settings

    • Letter: look for the e-news at startup
    • Letter: arrival of new messages every xx minutes
    • Select: automatically download new messages
    • Letter: Leave messages on the server '
    • Click OK

    E-mail POP accounts can only download the mail from the Inbox server.
    This will allow you to remove off the coast of the secondary workstation and leave it on the server.
    However, Pop cannot see or download other folders on the server: IMAP only can see other folders these are read remotely. But in IMAP because records are a same as server, removing in TB will remove also off server.

  • How can I do a silent install of Firefox 23 because the switch - ms does not work?

    I was able to do a silent install of all the previous versions of Firefox by using the switch - ms. But when I use it on the new version, the user interface comes up and he has never done this before. I tried different silent switches but non of them work.

    Not the most experienced at this, but you use the stub Installer, perhaps you can try the classic installer and try again?

    Hope this helps.

  • Two small buttons on the side of the switch just stop working - Tecra M5

    I had this problem before too many and I was told that the way to resolve the issue was a recovery CD, which means losing all my DATA and blabla... The problem is that the two very small buttons on the side of the switch just stop working.

    Just as that. They are always connected as when the laptop is on in standby or hibernation mode if you click on them it restart the machine. We tried something with Toshiba technician before and also their repair without success Center (change the purpose of the button, reinstall the program etc...) The only remedy was still a lot of recovery CD and a replacement of the machine, thank you for that. The sentence is still started. It could be a problem as cookies, just a wild guess or anything else.

    Now, nobody knows how to solve this problem, or had the same problem?
    Thank you. Olivier

    You talk about the presentation of Toshiba and Toshiba Assist buttons. Am I wrong?
    It seems that there might be corrupted registry keys or the common modules stopped working.
    Why? I put t know but perhaps I got a solution
    Try reinstalling the common modules.
    First remove it from the Add & Remove programs. Then restart the laptop and install the downloaded again common modules.

  • Best wireless network installation with the switch TP-Link

    Hi all

    Few question numpty maybe, but what follows... We just moved to a new (larger) home with thick walls and I want to set up a new wireless network.

    The current installation is:

    Fiber cable entering the House in the basement and connected the modem to the service provider that provides 150 mb internet. I changed the capacity wireless on the ISP's modem and connecting an airport extreme (2014 model) via the LAN to the modem. The extreme is in the office but on the 3rd floor is having connection problems than you can imagine. All rooms have access points CAT5e who all meet in the basement. I have two spare Aiport express and two Apple TV that I would use. Also I bought a TP-LINK 1000mbps (16 channels) Network Switch.

    Could someone please tell how the best set-up of my home network. For example, the Airport Express to the 3rd floor connected to the switch (wired) network or to an extreme in the Office? Apple TV also connected to the network switch?

    I would like to end up with a solid wireless network that passes without problem from extreme to Express necessary each time you walk and you want to use an Apple TV for television on the ground floor and one in our room.

    Many thanks and apologies once more for this very basic question... I have expanded my front (extreme Express) wireless network but just don't know how best to use the switch.

    Thank you

    The simplest up set... which is almost always the best game in place... would be to connect the switch 16 ports to the modem/router and then connect devices to the switch. In other words, if your modem/router has 16 + Ethernet ports, the simplest network configuration would be to plug as many devices as possible directly to the modem/router.

    Other variants are possible, for example, the network might look like this:

    Internet > Modem/Router > AirPort Extreme > switch > devices... or, you can connect certain devices to ports Ethernet on the AirPort Extreme and some to the ports on the switch.  One thing to keep in mind however... If there is a problem... Troubleshooting may not be easy since it will be difficult to know where the problem actually lies.  Much easier to all have, or of possible devices, connect to the switch.

    Unfortunately, the AirPort Express devices will be of real bottlenecks on your network.  These devices are notoriously slow as well as wireless, and even if they work well, the speed will be does not exceed 100 Mbps... since it's the speed of the port to the AirPort Express.  In fact, I expect each Express to provide a wireless signal in the range of 50-60 Mbps.

    Another thing to keep in mind of the wireless network is that Macs will usually a good work of tilting automatically to the point of wireless to the other as moving from one place to the other in the House... but the iPhones, iPads, PCs, and other mobile devices will do that very well... If they do at all.

    So with these devices, you will need to get used to temporarily disable the WiFi on the device and the device when you move in one region to the other, and then turn WiFi on must generally then pick up the signal from a nearby wireless access point.
