Transfer DHCP requires more 802. 1 q ASA5505 trunk

We run an ASA5505 with ip + licenses, which allows us to run multiple VLANs (in our case 3: outside, data and voice). Members of VLANs (the same two levels of security) voice and data a 802. 1 q trunk on eth0/4, passing the VLAN voice and data through the trunk to a 3750 switch.

Our DHCP server is the data lan. Is there an equivalent command on the SAA to the Cisco router command 'helper-ip address x.x.x.x"which should be placed on the SAA voice interface vlan (svi) to pass these dhcp requests? If this is not the case, how do we get the dhcp requests through the ASA? FYI "permit same-security-traffic inter-interface" and "allowed same-security-traffic intra-interface" are configured on the firewall.

We do not all entries in our dhcp server to Cisco phones litters, but phones are enrolled in the subnet out of Mgr call and use addresses at the level of the vocal range of dhcp on the server.

Strange, one for sure... any help is appreciated.

  • ESXi hosted VM requires more video RAM

    Hi, I have a Geforce 9500 GT on my ESXi 4.1 server. Some of the windows on the ESXi server machines require more video RAM, then the map server provides (24 MB I think) so I found a 9500 GT I had spare and added. I haven't set anything to the video card and ESXi is not sound using my server maps vga. Can I configure ESXi for my windows to use my Geforce 9500 GT, and you have a link or instructions somewhere?

  • How to use a virtual machine that requires more physical memory that I have?

    A colleague send me a Linux VM, he built on a machine with much more physical memory 4 GB I have in my Macbook Air.  When I started the virtual machine in Fusion, he said that the more physical memory virtual machine that I had and suggested that this would reduce the memory for the virtual machine to 3 GB.  I said OK and the machine started.  I did a lot of work in this virtual machine.  I suspended the VM because I needed to recover a portion of memory that he used for another application.

    When I try to start the virtual machine now, it says that it requires 4 GB of memory and that I should quit some applications or restart to free the memory required.  I tried both without success.

    Why the parameter / 3GB was not recorded when I suspended the VM?

    Given that I can't change the memory required for the virtual machine until it is properly closed and since then I can't stop the virtual machine without unsuspending it, I suspect that the VM is toast.

    Is it possible to recover the virtual machine?

    With VMware Fusion closed, you can remove the file from .vmss to to reset the VM to a shutdown state.  Note that whatever it is not recorded when he was suspended will be lost.

  • How can you ask a question that requires more than one sentence (although the limitation of the device seems to be characters)?

    Well, that answers the question above. Now for the real question. I need to regain my search bar of alternative search engines, and I don't want to start typing a search to get them (bad idea). I found the suggestion below but have no idea how "middle click" or how to get to the page mentioned "config". Can anyone help?

    If you want to restore the window previously used independently to manage search engines, you can enable or disable this pref to false with a medium on the subject click: config page.

       about:config page: browser.search.showOneOffButtons = false
    

    You will need to close and restart Firefox to make it work properly.

    You can open the topic: config page via the address bar. You can accept the warning and click on "I'll be careful" to continue.

  • Activation of Thunderbird requires more than TWO minutes after clicking on icon Thunderbird.

    PROBLEM: The Thunderbird program is slow to activate. When you click the Thunderbird icon, I expect Thunderbird Inbox screen to appear in a few seconds. However, after clicking on the Thunderbird icon, more than TWO minutes elapse before the Thunderbird screen appears. This problem existed for about a week. My OS is Ms 8.1. You can provide any help would be appreciated. Also, when this problem started, I received the following message "warning: this file is being processed.» Please wait until processing is complete, to pass messages. »

    Your anti virus (or attempt to Microsofts Defender grant) needs to be said is not to analyze the profile of Thunderbird folders, each time you open the program is my guess. The program cannot open files that are locked for scanning. As some of the files may be in the order of 4Gbv in size, it can take an AV program up to 10 minutes.

  • Tecra M5 requires more EasyGuard HDD password

    Hi all

    I was a complete key and changed some BIOS settings, specific WOL on my laptop. Now, when I try to start I get is more asked for the password (the blue screen with * etc.) but rather a message saying "error loading operating system".

    I've tried everything I can think of, but it seems that EasyGuard a death/disabled the startup HARD disk or has infact wiped.

    I just tried booting from the XP CD to see if the partitions are intact - I can see two with [Unknown] where it should say NTFS... clearly something to do with the encryption of disk HARD/safety...

    Help, please! A quick response would be fantastic!

    Did you change or remove the password of HDD in BIOS?

    Maybe try to reset the BIOS defaults.

  • Required more basic info - software updates for Tecra A4

    IV' e downloaded some software updates for my Tecra A4, but they all seem to have lack of basic information.

    Where the .txt files simple that shows the history of the files? Similar improvements have occurred? Or what bug fixes? Or is this installed just overwrite the old version?

    This is basic information that are included in any software downloaded from shareware and freeware sites and pretty much everywhere else so why not on the Toshiba download page?

    Hello

    Well, that's a good question, but as far as I know on the driver download site, you will find an option called more than information. You will find common information and a description. It seems that all the other information are confidential.
    I think that if you have problems with your device and you will be able to find the most recent version of some drivers then you must download and install.

    Toshiba Software is not freeware and also not shareware software. In this case, I can understand why Toshiba doesn't publish more information than necessary.

    Good bye

  • How can I require more RAM to my graphics card?

    I'm pretty sure that this question is thrown around a lot, but I can't really find an answer that helps my situation.
    So, I have a HP Pavilion p6-2480ea and I have 6 GB of RAM, but only 32 MB of this is dedicated to my graphics card. So I was wondering if I could dedicate more RAM for my video card? I have an Intel integrated graphics card, so I don't know about if it will hinder me.

    Thank you.

    Normally this parameter is in the BIOS on a desktop computer.  Now remember that the OEM motherboards have luxury may not allow the user to this area of the settings.  Check that setting (award shared with the integrated video graphics card memory) if there is no box for this setting, it might be a better option to add a video card to the system.

  • T410s Ultrabay problem - hard drive requires more power

    I'm working on upgrading a T410s to give it as a gift to my girlfriend. I've already upgraded the ram and had to replace the screen and both went very well.

    Now, I'm working on adding a second hard drive with the ultrabay. I'll keep the original SSD as my boot drive and you want to use the ultrabay for a normal HARD drive to increase the total space for her. It is a graphic design / photography major space would be nice.

    I bought a 3rd party caddy and a WD Black 750 g 7200 RPM drive through Amazon. I followed the advice that I heard somewhere that you need to make a shortcut of the old EVD to access the new hard disk drive. When I installed the ultrabay and booted up, the computer could not access E:. Nothing happened.

    I heard somewhere else ultrabay housing could use only 5 units of power (I don't know if it was watts or volts) and therefore the WD black drive series, I got is likely to need more power to operate (9-12 units). This noise to anyone who has installed a ultrabay correct? Maybe at the time where the T410s first came out, most hard drives use more than 5 units?

    Any recommendations? Thank you!

    I don't know what are the units of power, and I never heard of the the ultrabay on a T410s not giving a hard drive of all the power he needs. I must admit that I am very skeptical about the claim that you read.

    Perhaps the drive has not been initialized because it's new? If you are on Windows 7, click the Start button and type "create and format" in the search bar. You should see the drive it so that it can be initialized. Another way to get there is by going to control panel > administrative tools > computer management > disk management.

  • How can we increase the free memory space for application requiring more memory on OS 64 - bit Windows 7 Professional?

    How can you increase storage space free for a request that need more than 2 GB of memory on a 64 - bit Windows 7 professional OS?

    I guess it's a 32-bit application; a 64-bit application would have a 8 TB virtual address space.

    A 32-bit application can be given to a 4 GB virtual address space if it is marked with the IMAGE_FILE_LARGE_ADDRESS_AWARE flag. This is usually accomplished in conjunction with the indicator of this option .

  • EchoSign has a solution for applications that require more than 1 signature?

    We have a form that requires the employee to sign and the prime contractor.  The employee and the supervisor are often in 2 different places.  We want to use formscentral for the form.  We would like the form to go to the contractor for signature before it comes to our Department.  EchoSign has a solution for the form and the signature process workflow?

    If you send a document must be signed by several signatories, you'll want to set the role for different areas. The role is who is allowed to interact with this field. By default, the signers sign in order that their email addresses have been concluded in the To: field. It is important to keep this workflow in mind when configuring the signature fields.

    If you have a signature field, you can define the role of this field (which can be clicked to sign). Right-click on the signature for the 1 signatory field and select Edit. This will open a window where you can set options for this field. Select the signers 1st e-mail address in the drop-down list for the role: field.

    Repeat this step to associate all other fields of signature for the other signatories.
