Voice VLAN help please

My client has 2 SG300 - 52p and 5 SG300 - 28 p. We have installed a VoIP telephony system earlier this year. At the time of installation, we placed the phone on the native VLAN 1 System. Now, they want to pass the phone system to a new VLAN, because their class C subnet is running out of addresses. DHCP is managed by their Active Directory and their router/firewall is a box to sort out. The SG300 switches have a basic configuration only.

To move the phone system to a new VLAN, I created 20 VLAN on each switch. I then turned on VLAN auto voice. I have all the ports on each switch setting on the trunk. Computers are plugged into the back of the phone. I then created a virtual interface in the box to unravel for VLAN 20. Box unravel also manages DHCP to the new VIRTUAL LAN. Active Directory is always manage DHCP for VLANS native.

I ping from each switch to the bridge of the new VLAN. Since each computer I can ping the gateway and on the new LAN VIRTUAL phone system. However, phones will not seize an address on the VIRTUAL LAN and when they have the static value, they cannot communicate with other devices on the VIRTUAL LAN.

Any help would be much appreciated. I don't know what I'm on.

Here is an example of part of a switch configuration to work with Zultys phones where voice VLAN is 100 and data VLAN 10:

database of VLAN
VLAN 10,20,100
output
ID of the vlan 100 voices

interface fastethernet1
Description "RCP and voice."
switchport trunk allowed vlan add 100
trunk switchport vlan 10 native
!
interface fastethernet2
Description "RCP and voice."
switchport trunk allowed vlan add 100
trunk switchport vlan 10 native

In your case, you need a trunk port with 20 VLAN Tag on your firewall (or an access port to a separate physical port on VLAN 20.  The default gateway served on the phone (or put statically) should be the interface on intellectual property.  Then, you can also allow routing inter - vlan for admin access or MXIE if you use.

One thing to note on Zultys is by default I think the device profile disables LLDP, but on phones, it is enabled out of the box.  For the first time that a phone downloads its config from the Zultys it can turn of LLDP unless you have checked the box to keep it on.

  • Need help to set up voice VLAN in SG300

    Hello

    I spent too much time on it now and need help. I'm trying to set up a voice switch VLAN on a SG300 - 28 p. I need to charge a phone Cisco 7965 connected to a port on SG300 - 28 p to use VLAN 100, and a workstation connected to the phone to use Cisco 7965 on VLAN 101 by SG300 - 28 p. In the common Cisco IOS switches, this task is configured as follows:

    interface gi25

    switchport mode access

    switchport access vlan 101

    switchport voice vlan 100

    Trying to achieve this scenario with a Cisco SG300 switch turns into a nightmare. You will have to deal with a Dynamic of VLAN voice Auto Voice VLAN mode. Then, you must have a configured trigger and activated Automatic Smartport . I tried to do this in CLI nothing helps. Cisco 7965 receives an IP address of the access VLAN on Gi15 interface, which is 101 VLAN. I need to receive an address IP of the VLAN 100.

    The current configuration under Gi15 interface is as follows:

    interface gigabitethernet15

    activate the storm control

    broadcast storm control level kbit/s 10

    Storm-control include multicast

    port security throw trap 60

    maximum port security by 10 points

    port security mode max-addresses

    spanning tree portfast

    LLDP-med disable

    switchport mode access

    switchport access vlan 101

    ! next order is internal

    macro auto smartport dynamic_type unknown $native_vlan 101 $voice_vlan 100

    Now, I don't know how the macro auto smartport dynamic_type unknown $native_vlan 101 $voice_vlan 100 command in the config, and I do not know how to remove it.

    When I try to enter the command macro auto smartport type ip_phone_desktop under Gi15 interface, I get the following error message:

    The $voice_vlan macro setting is not configurable by the user

    It seems that the auto attendant smartport macro ip_phone_desktop can not apply the setting $voice_vlan with a value of 100. In fact, I explicitly does not use this parameter to everything in the order of macro auto smartport type ip_phone_desktop ; However, the SG300 switch knows that the voice VLAN VLAN 100, and he's trying to use this VLAN ID as the value of the $voice_vlan parameter, the macro fails.

    I tried statically configure the voice VLAN on the switch SG300 using the command id of the vlan 100 voice , but I couldn't get the ip_phone_desktop macro to configure interface Gi15 correctly. Then, I removed the command id of the vlan 100 voice and obtained SG300 to learn his voice VLAN ID of UC560 connected to the SG300 through a trunk port based on the port configuration (connected to SG300) for the trunk of the next UC560:

    switchport trunk vlan 101 native

    switchport mode trunk

    switchport voice vlan 100

    Cisco-switch macro description

    This is the command switchport voice vlan 100 who announces to SG300 via CDP VLAN 100 is a voice VLAN. When I run the command show vlan local VoIP on the SG300, I get the following result:

    VLAN ID - VPT DSCP Source MAC address Interface

    1                    5          46       default           ----                    ---

    * 100 CDP e0:5f:b9:xx:yy:zz gi28

    Thus, it is clear that the SG300 receives information from UC560 via CDP in port Gi28 VLAN 100 is the voice VLAN. However, I can not always apply the ip_phone_desktop macro to SG300 Gi15 interface.

    Also, I tried to set up vState ofoithis vlan auto-déclenché as well as the commands in global configuration State vlan automatic voice activated mode. Or setting changes anything view voice VLAN announced at Cisco 7965 where Cisco 7965 continues to use VLAN101 (access the VLAN assigned to the interface Gi15).

    Hello telecastle,

    The Macro just get in the way most of the time. A default state on the switch a user will set the id of the vlan voice with orders

    (config) #voice vlan id 100

    * This will create the vlan 100

    VLAN, VoIP? * You can use to change your defaults for dscp and cos a long with all the other settings.

    State of vlan (config) enabled automatic #voice

    (config) #interface rank fa1-24

    (config-if-range) #switchport trunk vlan 101 native

    trunk (config-if-range) #switchport allowed vlan add 100

    * This function will define the vlan native on the trunk to 101 for the data port and vlan tagged will be 101 for the voice.

    CDP is enabled automatically and should learn the features of the phone and get on the phone to the vlan 101 on this port.

    CDP of the UC should automatically fill in the switch of the SG. You may need to upgrade the switch to the latest firmware however. Also make sure that the DHCP server for the voice if the CPU must be configured accordingly.

    Let me know if this helps.

    Hi David,

    Thank you for the purchase of the switch.

    . Like what, even riding a bike, the switch is actually very easy to set up, if you practice on it...

    You mentioned that you use the 'phone YES picture' I assume you have a SF300 - 24 p or p/n command SRW224G4P-K9-NA.  Please be specific with the models of switches you use.

    Using the old SRW series or refreshed in the kernel SRWxxx-K9 (300 series) switch?

    First of all, make sure that you are using version 1.1.0.73 of the switch firmware. This change now or check that 1.1.0.73 is the active image on the switch.

    The switch has two areas to store the firmware images.  It stores the new firmware in the area of the image unused.  The administration for the firmware update Guide and select new firmware for the next reboot.

    CDP is enabled on the switch when using the new software, did not exist with older firmware, where my insistence to upgrade the firmware.

    ( Personally I would prefer that you have a role of catalyst for switching to your CME ISRG2 application, for purposes of support tech.) But this is the land of freedom..)

    I found the following when I added my SG300 - 28 p to a conscious UC500 of VLAN.

    The UC500 was vlan100 of advertising as a vlan voice, configured by Cisco Configuration Assistant, you could try CCP on your ISR.

    I got an IP phone that is plugged into the port of switch in the G7 and uplink to my UC500 via the Gig27 port.

    What follows in blue is a screenshot of my 300 series switch CLI interface.

    You will notice that the switch already filled both VLAN and port information, the only command that I added was "don't activate any complexity of passwords" and some usernames, including free from the screenshot below.

  • Microphone has stopped working - HELP, please!

    Hello.

    My plug-in headset and regular lapel microphone suddenly stopped working.  It was working before and I know that my helmet or conventional microphone are not broken.

    I noticed this problem when I would go to a Voice Chat room and trying to talk into the microphone, the volume bar would move only a little bit and not much.

    I checked all my settings of volume and nothing is low in the volume bar of the Realtek High Definition Audio, or the DD Realtek Audio Manager.  Everything is fine and when I lifted up the microphone, he is selected by default and indicates that it works correctly, but the sound does not come through.

    I am running Windows Vista Home Premium, my helmet is called Dynex, my plug in microphones are called Plantronics and the other on my Logitech webcam.  Help, please.

    ~ Marynonimous

    P.S. I also went to my menu of BIOS and changed my setting audio on-board car Enabled to disabled, and then back to Enabled, and this still does not work.

    P.P.S. My speakers work fine.  I hear people speaking from the voice chat rooms and hear the sounds of my computer.  I hear them on my helmet and my speakers when I unplug my headphones, so my speakers are absolutely perfect.

    Well, I don't have the connected headset on the helmet correctly.  I fixed it.  Thank you.  I'm sorry.  Thank you.  God bless you all.  Love and prayers to Jesus.

  • Having trouble getting the voice VLAN on the switch X1052P to work at all

    Can someone help me understand how to set up the voice VLAN X1052P? I spent several hours trying to get this working and it does not work. I spent about 4 hours on the phone with a Dell technician that night and he couldn't get it to work and finally gave up. He told me that I had to spend my warranty to ProSupport because he did not know how to solve the problem. What group of *. It's a simple configuration of VLAN. What must be so picky about? In any case...

    Setting up the VIRTUAL LAN must be fairly simple, but apparently on this switch is not. The user guide page 406 is not very useful except explaining what the different options. I must admit I am not an expert VLAN so I dunno I've misconfigured something. But remember, Dell technology could not operate either.

    Here's my situation... I have VoIP phones on my network connected to a network wall jack. Connected to phones are my computers of users. The computer of the user and its respective VoIP phone, both share the same data cable. Before replacing Cisco managed Internet service provider spend all it worked well. The problem is that they had direct access to our network so I removed the switch and installed the X1052P in its place. I talked to the ISP to let them know what I'm doing and they said everything I had to do was setup VLAN ID: 15 for the voice VLAN because this is the VLAN ID that the router uses to route telephone traffic. Router PSI is also the server DHCP VLAN 15 and issues IP for phones using 172.27.0.0/24 with a DHCP 172.27.0.50 range - 150.

    I tried to configure the switch using parameters of VLAN static and settings VLAN voice and neither one also seems to do what I want it to do.

    Network administration > VLAN > VLAN static

    Network administration > VLAN > Voice VLAN

    I activated the profile 'phone' on ports I want to added to the voice VLAN and it does not work. Moreover, 47 the switch port is connected directly to the ISP router and is configured as a trunk with the default port VLAN 1 unidentified and tag VLAN 15. For other ports I tried the general implementation, access and trunk of the parameters on each port to see if I could get something going and still nothing happens. When I set up the ports as General ports VLAN, I made adding VLAN VLAN 1 and VLAN 15 as a VLAN tagged not marked. It still does not.

    This is the short story from where I am now. Any help is greatly appreciated.

    FYI, as a follow up I finally solved the problem. I hope this information helps someone else that can encounter the same problem.

    After buying the ProSupport warranty upgrade ($121 out-of-Pocket mind you) and addressing a total of 4 technicians ProSupport expert technician a 3rd another level (only available via chat message between one of the ProSupport phone technicians and the 3rd Tier expert tech - i.e. I couldn't talk or chat with this person me) the consensus was that the material must be bad. When I bought the X1052P I bought two of them, so the best way to know if it was a bad switch was simply configure the other switch and see if the behavior occurs on this one, too. Well, this switch also restarted each time I assigned the profile 'phone' to more than 13 or 14 ports in the switch. It seems that it was not a hardware problem after all.

    I went back to the switch original and tried new things hoping that I could fall on a solution and it turns out that the solution was NOT to use the voice VLAN on the switch. It does not work!

    SOLUTION: I set the VLAN ID: 15 manually and no has not assigned any phone profiles to one of the ports. This is how I solved the problem.

    So he has bad software on the switch. I tried to see if there are updates of the firmware on the Dell support site, but there is none. Configure manually the phone VLAN was the solution. What a freaking nightmare which turned out to be. Maybe someone in Dell could note this problem and test in-house. And, if you want to compensate me for the 20 + hours I spent working on this problem, which has be great, too.

    Yes the packets can be lost during covering the election of the tree. If the status of the auxiliary port is bouncing between two ports, packages to send can be lost. If you want to try to leave it this way and still have 1 port throw, you can try to change the port on the ports 1 priority so that it is more likely to be the port to be scrapped.

    The following example configures a port to be less likely to be selected for transfer to the root bridge, even if the host starts sending of BPDUS.

    YES Enabled: 2 laptops connected to the ports 2,3, blocked traffic on VLAN10.

    1 phone connected to channel 1, the phone connects.

    So it's using, but for some reason any the vlan untagged on that port is blocked when the YES is enabled.

    I have installation this scenario on many switches cisco small business before and it works very well, so I wonder is this a firmware issue? or am I just being stupid and something wrong?

    Thanks for any help you can provide! :)

    Hi Vladimir,.

    It's something about Cisco still working. You are more than welcome to open the ticket with us and contribute actively. At this point, the only solution is to sue 1.3.5 firmware which does not show this problem.

  • problem with dhcp Cisco sg200 voice vlan

    I have cisco sg200 50 p connected to the switch cisco 3750. I just wanted to separate voice (vlan2) and data (vlan1) VLAN. I created vlan 2 as my voice VLAN and separate dhcp server for vlan 2 to give IPS for phones. However the phone ip connected to my voice vlan (vlan 2) does not receive the ip address of my dhcp server vlan 2.

    the dhcp server is connected to a switch with an access port (vlan2-voice) 3750

    two switches are connected through the trunk ports and allowed vlan 1 & 2

    IP phone is connected to sg200 via the access port (vlan 2).

    Note: there is a pc connected to the ip phone

    I'm really grateful if someone can help me with this problem

    Hi Ruchiran,

    To cover the base, ensure that VLAN 2 is added to the database VLAN on the 3750. Simple by using the command "show vlan id 2", if it is not found, you must first create the VLAN 2 on the 3750.

    Second, if you connect the same IP phone directly to the 3750 on an access port, vlan 2 unidentified, is the phone receives IP address as you hope?

    Then, on the trunk of 3750 connection to the SX200. Building the trunk when using a command like "switchport trunk allowed vlan remove 1-4094," then build the trunk more precisely with the VLAN ' trunk switchport allowed vlan add 2 "who will score 2 VLAN port." "

    On the SG200 switch, must be defined the trunk and VLAN Tag 2 on the port to connect to 3750 then the connection to the phone port should be 2 VLANS not identified as access port.

  • LLDP Voice VLAN

    I'll put up a D40 Digium Switchvox PBX phones and switches Cisco SG200.  The PBX is no not any COP or LLDP pub so I don't expect the switch to automatically determine the voice VLAN ID and I need to manually set.  How can I configure the switch manually to publis the voice VLAN via LLDP-MED?  I've been tinkering for hours and may not include the TLV voice in packets.  Be able to help?

    Thanks in advance,

    Paul

    At the present time, my switch is configured by default vlan 100 and all ports as 100u. When you connect a phone to any port, it is dynamically assign the vlan 1. Also note that I created the vlan 1.

    Hello

    I would suggest you start by changing the pool VPN to something else than the current LAN network and see if that helps

    These should be the configuration required to achieve this goal

    • First remove us pool setup VPN VPN
    • Then we delete the VPN Pool and create again with an another address space
    • When then attach this new Pool of VPN again to the VPN configuration
    • In the last step, we add a NAT0 / exempt for this new pool VPN NAT configuration and remove the old ACL line for the former group of VPN

    Try adding the following commands

    permit same-security-traffic intra-interface

    NAT (outside) 1 192.168.1.96 255.255.255.240

    Is there are always problems with VPN then I would maybe change VPN pool to anything other than something that comes into conflict with the LAN.

    In this case, these configurations should do the trick

    In order from top to bottom, they would do the following things

    • First remove the pool VPN and VPN configurations
    • Then remove the VPN pool
    • Remake of the VPN Pool with different network
    • Reattach the VPN pool for VPN configurations
    • Configure NAT0 to the new cluster of VPN
    • Remove the old line of the ACL of the configuration of NAT0

    In the CP installation folder, the subfolder Utils you will find a batch file that will kill the Preferences folder. You will lose all customizations, when the PC restarts a new folder will be created. The folder is located in your profile:

    \Users\\AppData\Local\Adobe and labelled Captivate 6.0
