troubleshooting scenario 1131

I have the following scenario to solve Monday and I'm hoping to collect some useful comments before this date. I appreciate your comments.

  • I have four 1131 autonomous AP who do not get their ip addresses from a dhcp server to the Public ssid. Tested on multiple clients.
  • The private ssid seems to work very well, of course, they get their from another internal server ip addresses.
  • The dhcp server is a cisco router 1811 old code running since 2005. It uses vlan999 on int f9 to distribute ip addresses to the wlan clients.
  • Tracing of the AP, the packets go to the router instead of the 1811 1711, so vlan999 does not work
  • APs use vlan999 for the Public ssid and I said that's not serious if bridge groups only go as high as 255, so the number of 0.999 subinterface and the number of vlan 999 and the 255 bridge group number do not match in the subinterface AP configs as they normally would.

interface Dot11Radio0.999

encapsulation dot1Q 999

no ip route-cache

bridge-group 255

bridge-group 255 subscriber-loop-control

bridge-group 255 block-unknown-source

no bridge-group 255 source-learning

no bridge-group 255 unicast-flooding

bridge-group 255 spanning-disabled

  • A cisco WS-C2960-24LT running 12.2 (44) SE2 lies between the EPA and the dhcp server. Network diagram is attached (not my design).
  • I have access to the APs and the router. I will be entering Monday swtich to see its config.

So my question is what to do if after graduating in this passage, I find that the APs are connected physically as it is 1811 router and trunking seems to be configured correctly?

Hello

The Switchport should be a trumk port, allowing all the VLANS that you use...

for example...

If you use vlan 100 and 999 for wireless and the management as 1, then

switch # en

conf t

int fa 9

switchport mode trunk

switchport trunk encapsulation dot1Q

switchport trunk vlan 1 native

end

Make sure you hv allowed all valns on the trunk port and make sure connectivity to the switch to the 999 interface vlan network to the heart.

and also IP for assistance under int valn 999 if necessary...

Let me know if that answers your question...

  • How to view the vswitch on ESXI 6.0 mac address table?

    Hello!

    Is there any medium vswitch to view for all (or special) mac address table CLI?

    It is very useful in troubleshooting scenarios, but I can't find how to do it.

    Thanks in advance!

  • Why will not enabled fonts to Suitcase Fusion 6 not appear in InDesign CC 2015, but will be in InD 6.0?

    I have all the latest updates to Suitcase Fusion 6 and Indesign CC 2015. I have the fonts that they are 'ON' in the suitcase, but when I open the files in Indesign displays only a partial selection of a font family. EX: Frutiger STD (OT) family is all about, but 47 Light Condensed appears as lacking in IND. If I open the file in Indesign 6.0, everything works very well, so it would seem that the problem may be with CC or suitcase has a bug that they need to fix (announcement to Extensis too).

    I tried the suggestions of the other posts, but nothing works.

    What I tried:

    • Restored preferences in Indesign

    • One replaced Mode Menu fonts 'name of the font of all research.

    • Restarted, rebooted, updated,... typical of troubleshooting scenarios.


    Any other suggestions?

    Sit down to set up files to run the tests that you have suggested, I got a response from Extensis. She suggested to clean the cache of fonts in the file menu of the suitcase. I had not thought to do this (not realizing that it was an option in the suitcase, using a cache cleaner in the past).

    It's done. A couple of weird things that happened, but after the closure of the programs again and re-opened, it worked. Hope that fixes it. Again, appreciate your help and advice for troubleshooting. Keep those in mind if it happens again, or as an alternative to other oddities of fonts.

  • With the help of two different devices for VDR to save the same virtual machines

    Hello

    I have VDR backup right now most of my virtual machines. I'm experimenting with some recovery scenarios disaster using VDR. I want to set up a new device, backup virtual machines themselves, but with a destination off. My question is, it would cause problems to have two different devices, backup the same virtual machines?

    I'm asking this is because I was looking at the notes of recent VMworld session on VDR and he says, regarding a troubleshooting scenario in which you must create a new device in addition to your current device, both devices back up the same virtual machines do not.

    If it is dangerous to do so because of the likelihood that two devices can save the same virtual machines at the same time, I could schedule the backup windows at different times to avoid this problem.

    Anyone have any ideas?

    I create a second local camera vDR and vDR distance and test it against a test VM. The vDR devices will have their own CBT files for each virtual computer, so they should be able to work together, but I would like to go through tests to see how they work well on the WAN. Make sure that you can transfer enough data to host daily data change.

  • HP P1102w EWS troubleshooting

    I have a HP P1102w who worked before wireless, but when I recently tried to reinstall I had problems with the built-in webserver (EWS) driver, eliminating my wireless feature. According to the device configuration page, the without wire is turned on and connected to my network, but I can't get real to work functions, and it does not respond when I try to find its IP address. Windows troubleshooting is not a solution, and reinstall the drivers, firmware update and installing ePrint all have not solved the problem. I am running Win 7 64 bit. Thank you.

    The SAP is not required for a printer to connect to a network.  The SAP is only another way to interface with the printer.  The requirement is not a two-way relationship.  A printer may be on a network without a built-in Web server, but the SAP are not accessible without network communications.  I assure you that the SAP is not not accessible does not cause the network problem, but it's a symptom of a problem of network communication.  The SAP is simply a site that is on the printer and accessible as any other site except that a number is entered instead of a variety of www.site.com .

    The problem you are experiencing is a network communication problem and cannot be resolved by the built-in Web server.  Your computer does not communicate with the printer on the network.

    It seems that the printer has a valid IP address, because it corresponds to a standard private class C address.

    I have seen this scenario before and reset the network in a specific way has the best chance of a resolution.

    1. turn off the printer and unplug the power cord from the printer and the wall outlet.

    2. shut down the computer in question.

    3. turn off the power to the router for 5 minutes.

    4. reconnect power to the router and wait for all the lights return to normal.

    5. reconnect the printer to the power cord and plug the cord into the wall outlet.  Turn on the printer if it does not start automatically.

    6. when the powers of the printer and wireless light turns a solid blue light on, start the computer to the top.

    See if you can access the built-in Web server.

    The problem is a problem of network communication and the above steps usually solves problems of this nature.

  • Differences between 1131 vs 1142N APs

    Hello

    I have problems to a customer who has four of 1131 who works alone. Details are not available at the moment.

    I configured 1142N executed before 12.4 JA1 (21 a), but I wonder what are the main differences between these units?

    I guess that the IOS will be older on the 1131 that will create some differences of course until I get to level, but what other differences I would be aware of these units?

  • Strange AnyConnect IPv6 interfere with IPv4 scenario

    I ran across this scenario last week and I don't know if I am missing something simple or if it is a real problem.

    Problem: It seems that ip6 can interfere with the IP4 VPN connections.

    My network is an extensive network of all the State affecting other agencies of the State (usually by having the firewall between us and them have VPN outside our firewall). Last week I set up a VPN connection to one of these organizations and connect them. The VPN configuration is a scenario of tunnel of split where they use the VPN tunnel for a specific application and all other traffic remains local.

    During testing, I noticed that the user could achieve some of their local resources, but not all. After a few basic troubleshooting, we determined that any time the user tried to achieve a local resource who had the ability of the IP6 (Please note that IP6 has not been configured, just cooked in the operating system) that they were not able to access this resource. However, they could reach IP4 resources without any problem. Ip6 was "unchecked" to the NETWORK card on the client and the resource server. Another resource told me that IP6 is impossible to be cut in 2008 and newer because microsoft has linked the many features and services OS inside.

    Simple ping tests proved that when the user attempted to reach resources with IP6 "built in" all traffic was trying to use IP6 by default (unless we used the switch-4 to force the IP4). The command prompt window would show a "General failure" when trying to ping any of these resources IP6.

    I was able to reproduce this problem in a different environment where a user VPN connects, try to ping several domain controllers and those who are 2008 and most recent attempt to answer over the IP6, then the old boxes answer on IP4. Needless to say that I'm getting nervous because it could alter a ton of services if/when the old domain controllers are upgraded.

    Does anyone have experience with this? I'm afraid that IP6 is the Protocol 'default' even when it is not configured and it is originally the users connected with Any Connect unable to access these resources even if the latter running IP4 and.

    Looks like that when you prefer IPv4 to IPv6 in Windows 2008 or Windows 8 and restart solve you the problem.

    Thank you

  • Troubleshooting SpeedGrade slowdown on major projects / deadlines

    Hi all

    I have been troubleshooting the issue that many of us have had to deal with: the slowdown or lag that makes SpeedGrade CC 2015 almost unusable on some large projects (Direct link). Basically, I have big smooth, responsive titrant with several layers, high output, adjustment even and layers After Effects compositions - up to a certain limit. More great, feature film projects require workarounds and I am trying to find out why.

    I've already eliminated:

    -GPU. GPU never never even reached 10% CPU usage or more. GPU memory usage never IM 40%. Acceleration, confirmed.

    -Memory. SpeedGrade seems never to consume 4 GB or more, max, excluding the memory usage of AE. I can have 22 GB of free memory on a 32-GB system and continue to suffer from the terrible lag.

    HDD/SDD. No disk access happens while I make adjustments.

    -Number of tracks. Reduction in the number of tracks in the project of one (of ten), the gap remained.

    -Linked securities / compositions AE / "exotic" files. Removed all of them, LAG remained.

    -Spike 's CPU use, but not 100%, and it makes no sense that the processor can manage complexity in a single element but starts trolling just because there are a few other clips on the timeline that aren't a cause

    Experimentation, I think what he peut is having a relationship with the following:

    -Length chronology

    -Number of (active?) clips on the timeline

    -Number of files in the project (whole, including other times?)

    -Total size or length of the referenced clips (active)?

    -Size of the project file (currently 6MB, which seems not extreme)

    I managed to get a workable unworkable situation by copying the pieces in an empty timeline and SpeedGrade Direct link, but this is less than optimal. I also managed to constantly increase the responsiveness and reduced offset 'simplification' of the timeline as described above, but these improvements seem to be progressive and it is difficult to objectively say that changes really made a difference.

    Any ideas how and why this happens? And more importantly, exactly when this happens?

    The idea of cache seems logical, but if this is a cache, it must be in the RAM somewhere (it has no current disk activity). So it is probably not a case of Sg to run out of resources, it's just the shuttle data back into memory... This would mean that, for now, is intended to keep the memory footprint of each scenario as small as possible.

    Absolutely agree with your recommendations: 2015.1 was already a great relief and I resorted to break the project into action, which makes more or less usable Speedgrade again for large projects. Also, it feels like I can get the some of the same effect by simply disabling groups of elements in the body, which causes Speedgrade to ignore (as opposed to disabling a track, which can still be reactivated to Speedgrade).

    The route of the EDL was not quite as bad as I expected to be the few times I used it, and I can recommend to any project that consists mainly of traditional publishing or plans effects fully rendered/exported. Basically, if all your belongings are scaling, basic transparency and knocked down the shots, it would take little to hurt!

  • Flash Player Installation troubleshooting Instructions are WRONG.

    They claim that the contents of the package includes a .pkg file in the folder resources.  He isn't here.  The standard update did not work on my Macbook Pro 17 "running the Mavericks since 2 or 3 years.  I need this .pkg file to run on the Apple Installer.  I followed the instructions and uninstalled Flash Player.  I have now no possible access to Flash content.  I need this .pkg file.  Does anyone know how to get there?  Anyone at Adobe will update the false information about the Troubleshooting Guide?  The Adobe policy do not provide phone support is cruel!

    @tolsenmd

    In fact, we do an installer .pkg for use with deployment of Apple utilities.  Grabbing the .pkg to our standard .app installation is not a good idea, because it has not been designed for this scenario and you will encounter problems (e.g. a preferences panel that falls down.)  Our formal .pkg install takes care of all this and is officially supported.

    The pkg is provided through our distribution agreement.  I recently wrote a blog post detailing this and more, which might be of interest.

  • A few troubleshooting questions

    I have a MacBook Pro (retina, 13 inches, early 2015) that is running OS X El Capitan, Version 10.11.4. I really like to use it, but there are a few questions that I have dealt with recently that I would like help troubleshooting.

    1. sometimes, I look at Netflix while doing other things on the computer. Sometimes my computer fan will speed up until I have to shut down the computer and let it slowly downwards. Is it normal when there are too many used battery power, or the problem can be corrected?

    2. I have an external hard drive WD MyPassport Ultra 1 .5TB, which is set up with my laptop. Lately, I've especially been "Finder" open with it to sort the files it contains. The hard drive seems to work fine, but when I shut down my computer or let it go to sleep with "Finder" open, the following error message appears when I wake up the computer (see image).

    However, even when the message appears, none of the clickable options are actually clickable and just show the loading icon. Instead, I have to force quit 'Finder' and when that finally works, the only option is to force eject the hard drive and plug it back in. (then it works fine except when I let the computer go to sleep, and then the process begins again. What should I do? This doesn't seem to be a problem with the external hard drive or with the computer?

    3. lately my computer has been freezing, usually if it is not always when the Finder is in use (sorting files). It happens at random times, not always. First the cursor freezes / stops moving, then the trackpad doesn't work anymore (do not click). The only solution I've used restarts the computer, which solves the problem, until it happens again (which could be anywhere from 30 minutes to about 3 days later). How can this be repaired?

    4. I also had pop up ads when I'm even not doing anything on the internet (Safari is usually open when he arrives but reduced or hidden). What are these pop-ups? They are bad?

    Sorry for the many questions!

    Thank you!

  • Summary of complex scenario (counties)

    Hi all

    Looking for inspiration and ideas with this little teaser

    I'm trying to find a common approach to the production of four counts (A, B, C and D) indicated in lines 1 to 5 below. This function of a table that contains about 4 000 entries.

    In affect, I try to summarize the different permutations in the classifications of four cells show in the image above, using a common approach. I might add a column for each company and use wild-card account, but I'd rather keep the table of (imported) origin of tact - I know that I could build a table of distinct society in another piece of work, but there must be a smarter way to achieve this.

    The legend below presents an overview of how the data looks like with different options (style truth table). The reference column contains a master list starting with RE - unique references.

    NC and P columns contain company names. There are two additional columns and the television that contain one or more numbers starting with- and TV - respectively.

    The idea is to check that the RE has a link to references or TV in the respective columns when there is a company name in the naming context and / column P

    There are a number of scenarios based on conditional counts in two columns: following NC and P with the possible permutations:

    Swap 1: Where there is a company name in the column "NC" count the number of:

    • RE links to OF
    • RE TV links
    • RE links to OF and TV
    • RE completely unrelated
    • More than one company with no link

    Swap 2: Where there is a company name in the column 'P' count the number of:

    • RE links to OF
    • RE TV links
    • RE links to OF and TV
    • RE completely unrelated
    • More than one company with no link

    Switch 3: When there is an entry in the column "NC" both "P":

    • RE links to OF
    • RE TV links
    • RE links to OF and TV
    • RE completely unrelated
    • More than one company with no link

    At this point, my head began to ache - would be very grateful and ideas on how this could be done.

    Thanks in advance

    Perry

    If I understand correctly, you can compile your different counts using COUNTIF with the * wildcard, something like this:

    For more convenience in formulas to set up your data in a table and your account in another.

    Here are the formulas in the table 'Account':

    B2: = COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$F,"*DE*")
    C2: = COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$F,"*DE*")
    D2: = SUM(B2:C2)
    B3: = COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$G,"*TV*")
    C3: = COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$G,"*TV*")
    D3: = SUM(B3:C3)
    B4: = COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$F,"*DE*",Data::$G,"*TV*")
    C4: = COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$F,"*DE*",Data::$G,"*TV*")
    D4: = SUM(B4:C4)
    B5: = COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$F,"",Data::$G,"")
    C5: = COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$F,"",Data::$G,"")
    D5: = SUM(B5:C5)

    You can learn more about COUNTIF here (you can also access it via help > formulas & functions help menu.)

    For more information on the search for wildcards of 'wild' in help > formulas & functions help

    The function works with pairs of columns-condition, where you add a reference to a beach (usually a column because it's more convenient) and then apply a 'condition' against it, indeed the application of several filters.

    You can add pairs more than necessary.
