Multiple vlans configuration issue with RV016 router and SG 300-10MP witch

Hi,
I have to configure multiple vlans served with a unique DCHP server . As first step, I just will The DHCP server to serve 2 vlans. The following is the hardware and configuration that I implemented :
Router (RV016 10/100 16-Port VPN Router) as gateway mode:
IP : 172.16.0.1/24
DHCP Server :
IP : 172.16.0.2/24 GW: 172.16.0.1
2 subnets :
172.16.1.0/24 GW: 172.16.1.1 to serve vlan 1
172.16.2.0/24 GW:172.16.2.1 to serve vlan 2
Switch (SG 300-10MP 10-Port Gigabit PoE Managed Switch) as layer 3 mode:
IP 172.16.0.254 (vlan 8 default)
Vlan 1 : 172.16.1.1
Vlan 2 : 172.16.2.1
1 device connected on each vlan
a workstation on the vlan 1
a laptop on the vlan 2
In this scenario (see the attached pdf file) the DHCP server is connected on a router, hosts on vlans dont receive any IP address.
But If I connect the DHCP server on a trunked switch port and adapt the DHCP server gateway 172.16.0.1 to 172.16.0.254, hosts receive ip address properly.
I have to connect the DHCP server directly to the router. How can I do that, what is wrong in the configuration ?
I hope the explanations are clear enough and my English too
Any help will be highly appreciated,
Zoubeir

Hi Eric, the small business group doesn't support the ASA config, but  I can help with the switch.
A couple things I notice in your description-
48 port (192.168.1.254) and the other 24P (192.168.1.253)  we have a  second vlan 20 set up on the 24P switch (192.168.2.253)  we have ports  1-12 set for vlan20 (untagged and trunk), the remaining ports on on the  default vlan 1.
The connection between the switches, is it 1u, 2t?
The link between the switches should be 1u, 2t, the switches support the trunking and vlan tagging, meaning all communication will work fine.
We have the 24p and 48p switches connect using GE1 and GE1.  We are unable to ping a device on vlan 20 ( on the 24p switch
The 24p switch should be in layer 2 mode, if you have the 48 port l3 switch upstream. Additionally, you need to have the default gateway set on the 24p switch.
We have a static route set on the 24p switch (0.0.0.0 192.168.1.0). 
Between the switches, it shouldn't require any static routes, assuming you correctly trunk / tag your ge1 ports, with both switches operating in l3, the ip route table dynamically builds the connected routes, therefore a static route is redundant.

  • Issue with Linksys Router and Modem with Vonage Device

    Hello,
    I have a Linksys Router and Cable Modem.  Plus I have Vonage for my home phone.  I have been having several problems and now, my Vonage phone will not work at all.  I have cable internet and my ISP is Cox Commuication.  I do not know how to connect my Vonage device with my Router and Modem.  People have been giving me advice, but nothing has worked.
    Does anyone know how to intergrate all three of these items together?  Basically which plug goes where.  Currently my phone is not working.  The only thing that is in use right now is my linksys cable modem.  I have the power cord plugged in, the blue cord from the modem plugged into my laptop, and the cable from the modem to the wall jack.  Please help.  Thank-You!
    Linksys Router:  WRT54G version 6

    The router should be online first. Can you get into the router's configuration page?
    The box said windows xp or better... So I installed Linux!

    Hi Santosh,
    I think the Reporting Services integration works with SQL Server 2008/2008 R2. When the SQL Server 2012 is installed, there is an option to install Reporting Services - SharePoint bits. Details can be found here:
    http://msdn.microsoft.com/en-gb/library/jj219068(v=sql.110).aspx
    Once the Reporting Services components have been installed you should be able to configure the SQL Server Reporting Service Application and use the Reporting Services content types in your SharePoint libraries
    Hope this helps

  • Ethernet configuration with SMC router and Titanium

    This concerns a Titanium Powerbook G4/500 and an SMC 2804WBR router.
    I plugged in a known-working Ethernet cable, and in System Preferences/Network, under Network Status for Built-In Ethernet, I got the message "The cable for Built-In Ethernet is not plugged in." A hardware test shows the Ethernet port to be functioning, but the TCP/IP tab, set for Using DHCP, shows no IP address, subnet mask, or router address. Renewing DHCP lease accomplishes nothing.
    I went to the Ethernet tab and set the drop-down to Manually (Advanced) instead of Automatic. With a little experimentation I found that 10baseT/UTP in either full- or half-duplex connects with the router and lets the machine go on the Internet, but 100baseTX will not. The router lights for link and 100baseTX go on, but no addresses appear in the TCP/IP tab.
    I use 100baseTX with a G4 and a Pismo Powerbook, so I know the router can work just fine at that speed using an Ethernet cable. Is there some glitch or weirdness peculiar to the original G4 Powerbook that won't allow it to communicate with the router at full speed? Is there some configuration through Terminal or elsewhere that will fix that?

    Hi,
    the PVDM is used when you E1/T1 interface. in your scenario you need to configure SIP trunk between your Voice GW and ISP.
    you need to confirm the below settings:
    Codec
    SIP sever ip address
    DTMF
    you will create voip dial-peer toward your ISP and another dial-peer toward your call manager.
    in this you are deploying CUBE. you need to configure
    voice service voip
          allow sip to sip
    don't forget to add CUCM and ISP in the trust list under voice service voip
    HTH

  • Is the Time Capsule wi-fi router compatible with the Nest thermostat? I've read where there are issues with the Nest and Airport Extreme (AE)? Is AE used in the Time Capsule?

    I've read where there are issues with the Nest and Airport Extreme (AE)? Is AE used in the Time Capsule?
    If so, i already have a wi-fi router, so can the Time Capsule simply be used for wireless backup instead of as a router if there is conflict?

    A TC is fundamentally a AE with a sata chip included to drive the hard disk. Some slightly different bios to include disk functions, although most of those are also on the AE. So as a router it is 99.999% identical.
    And yes, if you have another router you can easily bridge the TC and use wireless for backups and internet connection. Once you no longer route through the TC the issues with most NAT problems including port forwarding should disappear.. mostly this is due to all apple routers using NAT-PMP instead of upnp which is the near universal standard for opening ports.. without upnp apple keep their routers more exclusive.

  • WRT160N - does it support multiple vLan configurations?

    I'm trying to find more detailed tech. specifications of this thing (WRT160N), but unfortunatelly I get only some basic marketing messages... I need to understand if this router supports vLAN configuration, as I'm thinking to have IPtv and internet on the same. My provider does integrates the IPtv into separate vLAN, but their HW is not too good in other perspectives... So I'm thinking about linksys.
     So does it support multiple vLAN configuration (i.e. dedication of separate vLAN to exact port)?

    No. VLANs are not supported in Linksys devices. You'll have to look at Cisco Small Business or better.

  • Driver issues with HP Z440 and SCCM 2012 R2?

    Greetings, we received our first charges of Z440 workstations last week. We immediately downloaded the HP Z440 driverpack from http://ftp.hp.com/pub/caps-softpaq/cmit/HP_Driverpack_Matrix_x64.html and imported those into our System Center Configuration Manager 2012 R2. Of course we did use the Win 8.1 drivers to inject into our boot image and wie normally imported the Windows 7 drivers for the Windows 7 deployment.Well, unfortunately SCCM WinPE5 does not show any drives installed, even with the correct drivers installed. We even tried to import  the WinPE 5 driver pack and the drivers from SoftPaq download manager, but none of those seemed to work. Is there any known issues with Z440s drivers and SCCM? Please help me out on this, it's pretty urgent. Thank you & kind regards

    The problem cannot be replicated. My Z440 has an 1TB WD SATA drive attached to port 0 of sSATA 6 Gb/s. Download and install the ´Windows Assessment and Deployment Kit (Windows ADK) for Windows 8.1 Update´:   https://www.microsoft.com/en-US/download/details.aspx?id=39982 Download and extract the ´Intel Rapid Storage Technology Enterprise Utility and Driver for Microsoft Windows (64-bit Editions)´, 4.1.0.1046 B(12 Nov 2014), sp69762.exe:http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=6978829&swItemId=wk_139802_1&swEnvOid=4059 Copy the IRST driver “64bit_RSTe_4.1.0.1046_F6_Drivers” abd sub folders into “C:\z440_x64\64bit_RSTe_4.1.0.1046_F6_Drivers” Open the ´Deployment and Imaging Tools Environment´ command window as administrator and create bootable USB media:copype amd64 c:\winpe_x64 Dism /Mount-image /ImageFile:c:\winpe_x64\media\sources\boot.wim /index:1 /MountDir:c:\winpe_x64\mountDism /Add-Driver /image:C:\winpe_x64\mount /driver:C:\z440_x64 /recurseDism /Get-Drivers /image:C:\winpe_x64\mountdism /unmount-wim /Mountdir:c:\winpe_x64\mount /commitMakeWinPEMedia /UFD c:\winpe_x64 d: Boot Z440 to F10 Setup.Set Factory Defaults and exit.Boot to WinPE media created above.I also tested the wim file as the boot image in SCCM 2012.

  • Has anyone received an update on apple tv issue with HD movies and what they are doing about it

    Has anyone received an update on apple tv issue with HD movies and what they are doing about it

    Whatever the rep told you, it is complete nonsense. There is clearly a problem at your end, the Apple TV 3 is capable of more than the Apple TV 2, and you clearly have the Apple TV 2 working perfectly. Since the Apple TV 2 is able to download from the Internet properly, then my suspicion would be your problem lies on your local network. Interference is a common problem on local networks.
    Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

  • My macbook pro has a virus/trojan that is resetting the EFI via apci and it is getting root access privileges. It seems to be creating multiple aliases that bundle with rogue apps and preferences so it is very difficult to control or fix. Please help..

    My macbook pro has a virus/trojan that is resetting the EFI via apci and it is getting root access privileges. It seems to be creating multiple aliases that bundle with rogue apps and preferences so it is very difficult to control or fix. Please help..It all stems from the "about donwloads" PDF which kicks off the restructuring of the OS..

    Well given the fact that it is not just myself who is infected and also that this is my 3rd macbook in 1 year because the other 2 efi's were compromised to the point where they were unusable, and also that I must've been to the mac store no less than 100 times in a year for these issues, I beg to differ. Here is what I can show you. This has been ongoing for over a year now.
    I will try and show you as much as I can.
    1) Here is what I see when I run mount from terminal:
    /dev/disk0s2 on / (hfs, local, journaled)
    devfs on /dev (devfs, local, nobrowse)
    map -hosts on /net (autofs, nosuid, automounted, nobrowse)
    map auto_home on /home (autofs, automounted, nobrowse)
    localhost:/4zOta2Q9FMiMnRjTROIbhU on /Volumes/MobileBackups (mtmfs, nosuid, read-only, nobrowse)
    Why on earth is /Volumes/MobildBackups my localhost is beyond me. I don't use iCloud and Mobile me is obsolete.
    2) Here is what I show when I run ls -al /*/*/*/*.efi from root
    -rw-r--r--  1 root  wheel  994464 May  1 00:33 /System/Library/CoreServices/boot.efi
    -rw-r--r--  1 root  wheel  994464 Oct  2  2012 /usr/standalone/i386/boot.efi
    -rwxr-xr-x  1 root  wheel  115716 Dec 13 14:08 /usr/standalone/i386/tmbootpicker.efi
    As far as I know my boot.efi should not change everytime I boot my machine.
    3) Here is something very interesting. When I run cd /dev followed by ls -al look what I have;

  • Apple Support admitted an Issue with WEP authentication and some Routers

    After reading many posts here and other places I logged a service call to Apple support. With the particulars: AT&T U-verse 2 Wire router would not connect with WEP would connect with Security disabled. I wanted a call logged before I went past the return time
    I got a call back immediately after a few basic questions I was passed to a product manager for ipads, it seems connectivity issues are taken seriously.
    The upper level support said there were known issues with some routers and WEP security we steeped through changing the security and it works fine now.
    Bottom Line:
    Apple knows there is an issue with some routers
    They were very helpful and acknowledged the issue.
    He even stayed on the line while I reconfigured one of my Windows PC to make sure it connected to the new settings
    I suggest to all to log a call and get a tech support involved before taking the iPad to the local store
    They certainly new their are some connectivity issues. If that does not work you can always return it.
    He did not admit it was a Apple issue and did not commit that Apple was working on it but it is something they are aware of.
    So skip the Apple store got right to tech support.
    Just my 2 cents.

    "But folks need to go straight to tech support. I live in oz, so it will be interesting to see if they help me.. or not.. but if support gets inundated they will fix it or have a massive recall (not likely on the latter)."
    Can't agree more. I used to manage a tech support department and it is all about the numbers. No matter how many forum entries the issues that get addressed are dictated by the reports.
    So for those that are buying new routers contact Tech Support first even if you end up getting a new router the call is logged that will get Apple's attention.
    People that are not familiar with post launch processes have no idea how things that need to get corrected and enhanced are dictated by support requests

  • Help with connecting MacBook Pro with Cisco Routing and Switches?

    I'm running a CiscoASA 5510 router with several Cisco WS-C2960-48TT-L switches on a local network to connect with MacBook Pro. I need to be able to restrict access to specific users via their computer MAC address. ie: Joe Blow is limited to connecting through Switch 1 on port 10 and anywhere else he tries to plug in will simply not work.

    You need to look at the documentation that came with your router and switches. Or ask your network admin to set it up. Your question has nothing to do with your Macbook Pro configuration. MAC filtering is done in the router not in the computers/devices connecting to the router.

  • Issues with Exchange Account and Q10

    Well, I hate to be writing this, but I'm hoping that there might be someone out there that can help get past some first day issues I am experiencing.
    The background: I have a long history with legacy BlackBerry devices, and almost as much history with iOS devices. My most recent phone was an iPhone 4S, and I make extensive use of iCloud to keep my iMacs, iPhone, and iPad connected in real-time. The setup worked. It wasn't perfect, but it worked. However, because I used to have a BlackBerry device (most recent the 9930) and because I don't use the iPhone for more than e-mail, iMessage, and phone calls (generally speaking), I decided to give the newest BlackBerry device a shot. So I bought a Q10.
    At this point I feel compelled to say that the hardware is everything I had hoped it to be. It's solid, has a good weight, and appears to be made very well. I have no complaints with the hardware, including the keyboard (a big selling factor for me), so I won't really get into the hardware as the issues I am experiencing all have to do with the OS. Let me also say that I am very familiar with the iCloud integration issues (missing Contact photos and disabled Calendar sync), so I'm not voicing a complaint over those issues in this thread.
    I have connected my Exchange account. I used to have everything in Exchange before I moved my entire computing world over to Apple, and now I keep Exchange around for e-mail. Therefore, I have no contacts, no tasks, no notes, very limited calendar entries, and a massive amount of e-mail on the Exchange server. However, to test everything out, I have added a single contact record so I can see it show up on the phone and be able to test two-way sync between the Q10 and Exchange. And here is where the first issues crop up. It looks like Exchange connects and then disconnects at random. For example, if I open my Contacts on the phone, I see the one contact (called John Doe). Then, as the phone is sitting there with the screen on, the contact will disappear and I will see a "Start adding contact to your contact list" notice on the screen. Then, after a short period of time, the single contact will return. It is important to note that the entire time this is happening, the All Contacts option is selected in the list so that all available contacts are shown. Additionally, I have SIM card contacts turned off, but if I alter the selection in the view list (All Contacts, Favorites, etc.), the SIM contacts will re-appear when I return to the All Contacts view. At the same time, even though I have turned off SIM Contacts in the settings, the setting has reverted to show SIM Contacts. If I turn off the setting again, SIM Contacts still show up. Possibly related: I can't delete contacts on the SIM card, no matter how many times I try, and it now it seems that I can't get SIM Contacts to go away in the Contacts app.
    Likewise, Exchange seems to connect and disconnect from Calendar. I go to the calendar and move day by day to June 15th. I see an entry that I know is from Exchange (I have no other connected calendars at this time), and it is in blue. I change the calendar color to green and the entry changes color, as expected. However, if I jump back to today and then scroll day by day to get to June 15th again, the calendar entry is missing. After a few seconds, the entry re-appears, but it is, once again, in blue. The setting has reverted itself, and it seems like Exchange is completely disconnecting and automatically reconnecting to the phone like I am setting it up again for the first time. Very odd. As I'm typing this, I just saw something odd. I swiped to wake up the phone, and the active frames screen was the visible screen. The calendar app is still running (since I left it running, minimized, when the phone went to sleep) and the date shown in the active card was Jan 1, not Jun 8. Why? The date (and time) on the phone is correct and is set automatically by the cellular system.
    Nevertheless, looking at BlackBerry Hub, I see only two e-mails in my Inbox from Exchange, even though I have roughly a dozen in my Inbox. The rest are filed in sub-folders. And bam! Just like that... I get the "Add Accounts" screen while looking at the Hub. In other words, as I was typing this, I first saw two Exchange e-mails and then, out of nowhere, the e-mails disappear and I see the "Add Accounts" screen as if no account has been connected.
    So... first question: Is anyone else experiencing this issue? This is very strange, and very frustrating. Second: could this be related to the large amount of e-mails I have stored on Exchange, some of which have large attachments? I selected "Forever" as the sync history length. I have my concerns, however, if this is related to loading historical e-mails onto the phone (in other words, the first sync with Exchange) because there is no reason that I can understand that the phone would blank out as if no account was connected at all. I can understand lag and stuttering while the history is syncing, but not a complete disconnect and reconnect. Considering all of the issues with the one and only contact record disappearing, the calendar entry for Jun 15th disappearing and then reappearing with the wrong calendar color, and e-mail in my Inbox incomplete (two of a dozen e-mails) and ultimately disappearing, I feel like this OS just has some real, significant issues.
    Full disclosure: I do want iCloud to work and am a fan of Apple products, but the lack of full iCloud sync support is not a big enough issue for me to want to send back this phone and/or see it fail so miserably. I will happily move my info from iCloud into Exchange, Google, and/or set up a new Exchange account for personal use (Office 365) because I am not wedded to iCloud per se. But, I won't go through that trouble if I can't even get my first account to work properly. It should also be noted that I do have a basic Google account (non-paid) and I had previously attempted to connect to it. However, I was experiencing the exact same issues with contacts disappearing, e-mail disappearing, etc. So I deleted that account. Truth be told, I deleted the Exchange account as well, and then re-connected to Exchange only to test one account at a time. Unfortunately, even with Exchange only, I am seeing very strange and frustrating behavior as described above.
    Help... please. I want this to work but the frustration I am feeling is growing worse by the hour.

    To follow-up with this issue:
    I ended up performing a security wipe on my device. The security wipe finished, and I was about to reconnect with Exchange when I decided to visit our host's web site to see if they had any articles covering the issues I was experiencing. While they didn't have anything specific, I did find a step-by-step guide to connecting a BB10 device to Exchange... and right there at the end, it said "Do NOT enable memo sync."
    I contacted support, and the rep told me that OS 10 has an issue with memo sync and it can cause all sorts of unpredictable behavior. Now, whether or not this is accurate I can say this: So far, the device is not disconnecting and reconnecting like it was before. Problem is, is this a result of not enabling memo sync, or is this a result of the security wipe?
    I may have overlooked it, but I don't recall reading anything about that anywhere else. I'm tempted to try re-enabling the memo sync to see if everything blows up again. At least that way I can see for myself if the memo sync is a real issue. Of course, perhaps it's an issue with SherWeb (our host) specifically. Hm...
    Anyway, for those that were interested, and for those that may come along in the future with a similar situation, the strange behavior that I first reported is no longer happening. I just don't know if it was a result of a security wipe or a result of not enabling memo sync with Exchange.

  • Since the Mountain Lion OS update today I've had issues with internet connection and e-mail, has anyone else?

    Since the Mountain Lion OS update today I've had issues with internet connection and e-mail, has anyone else?

    That's what I would have thought, but even after saving the setting, as soon as I shut down my computer or log out of Mail, it automatically defaults back to 25. It's a bit frustrating.
    Now I just need to figure out how to get rid of those horrible pop-up banners but still have my glass sound and number of emails in the red dot when I get an email...
    These little tweaks are the only thing I HATE about upgrading my OS.

  • I am having major issues with Logic 8 and want to reinstall.

    I am having a lot of issues with Logic 8 and want to do a re-install. What is the procedure and what do I need to uninstall first. I need to be careful, because I don't want to affect my Logic 7.
    Any suggestions?

    What problems?
    The first thing to do is trash the preferences. As far as affecting Logic 7, once you install 8, 7 is "forgotten" about. I'm assuming your L8 is a real version, not a "borrowed from the interweb" one.

  • My itunes account shuts down for no reason.  It wont recognize my iphone and there is an issue with network connectivity and itunes.  I have already  reinstalled itunes and did a syste restore on my computer, firewall checked and virus scan done.  Ideas??

    My itunes account on windows xp shuts down for no reason.  If even try to delete something from my library it shuts down.   It wont recognize my iphone and there is an issue with network connectivity and I can't connect to the store.  I have already  reinstalled itunes and did a system restore on my computer, firewall has been checked, itunes is ok on firewall and virus scan done.  Ideas??

    Same problem. I can see the itunes store so not a problem with windows firewall. The account is active on my iphone so i know i am not locked out. I can connect the PC to my iphone so i know itunes is working ok. It is just logging into itunes on this pc which doesn't work. Only thing I can think of is that the email address I use for my apple id has been offline for a while and is working again now, I'm wondering whether this has been the case for others who are having this issue?
