• 6500 QinQ vlan native risks

  I have two questions:

  (1) 6500 (regardless of the SUP) do not support the standard 802.1ad correct?  "QinQ" features are not standard?

  (2) can someone help me understand why tagging vlan native is listed as a required step when configuring switchport dot1-tunnel mode?

  (http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2S...)

  I understand VLANs jump... etc but I do not understand how this relates to the creation of a tunnel port.  For me, a tunnel port puts all the data in the provider / S-VLAN defined on the port tunnel with "switchport mode access vlan x" This includes labeled and not marked traffic coming from the CE marking on the port tunnel.   I understand best practices for tagging vlan native on the base in general... switches but why the tunnel ports invites and it's necessary?

  I'm missing something basic here :)

  Thank you!

• Change the order of VLAN native?

  Can someone refresh me please as to what the command is to change the VLAN native for the whole switch? (IE: not only on the trunk, I mean the default native for the whole switch). Thank you

  Can someone please refresh me as to what the command is to change the Native VLAN for the entire switch? (IE: not just on the trunk, I mean the default native for the entire switch). Thanks

  Hi Steve,.

  By default, there is only one VLAN for all ports. This VLAN is called by default. You can't rename or delete VLAN 1.

  If you're talking about a management VLAN is nothing else than a VIRTUAL local network that is used for managing in-band of the network switching devices.  To configure this on a switch, you must create a Switch Virtual Interface (SVI) that is mapped to this VLAN, and then assign this virtual interface an IP address.  On a Cisco switch, it would look like the following.

  Interface Vlan99
  IP 192.168.1.1 255.255.255.0
  No tap

  I also want to make something very clear.  Your management VLAN is not to be identical to your VLAN native.  Question, please make sure that they are different.  Your management VLAN must only carry the traffic of in-band management and should not be the default VLAN.  By in-band management traffic, I am referring to SSH or telnet (Although telnet is not recommended because it is not safe).  Traffic such as BPDUS, PagP, CDP, use the VLAN native who is the vlan 1. But if you change the vlan native then CDP, VTP/PagP will always use the vlan 1 but packages will be marked. Only DTP uses vlan native so if you have changed the vlan native then DTP would use the new VLAN to send images. With PVST + BPDUS of course run on all the VLANS.

  Hope to help!

  So useful note the position

• Incompatibility of VLAN native of CDP

  Hello, I have problems with incompatibility of VLAN native between two Cisco switches. I'm confused why other manufacturing going on works, but Cisco didn't. Can I blame CDP here and I hope that a solution for this? Thank you very much! Tomas

  Hello

  The vlan native must be the same for both switches. On the 3750 vlan native is 35 and on the 2960 vlan 1 native. Try to change 1 to 35 on the 2960 and test again.

• Question of VLAN native of UCS

  All,

  I have a problem that I can not just wrap my mind autour.  We have UCS setup in a lab with 2 interconnections connected to 2 nexus switches 5510.  The nexus switches are passed to the network via a Switch 4900 m.  All circuits are configured and tested as functional. All routing is configured and confirmed.  I have a problem in UCS, which is confusing to me.  In the lab, I kept the VLAN native to the vlan1.  I have the Setup VLAN 2-10 on all switches test and interconnections.  I created a service profile that contains 1 network card and placed it in the VLAN 7.  I installed Windows 2008 on a blade using this service profile.  In the operating system I statically IP'ed the NIC for the schema used in VLAN 7.  The OS, I cannot ping another device located in the vlan 7.  Also, I can't ping a host on a different VLAN.  If I place a check on the VLAN 1 as the vlan native I still cannot ping anything.  If I place the audit for vlan native to vlan 7 I can ping hosts in the same vlan, as well as outside of the vlan.  So why should I place vlan 7 as the vlan native when all my boxes are set up in the vlan 1 is the vlan native?

  Thanks for any help,

  Ken

  Ken,

  When you allow some VLANs on your Service vNIC profile you will need to set the VLAN native. This is because the way you have configured currently you are only "allowing VLAN 15', but you're not marking it.   It will work fine for ESX or Linux which allows to assign the dot1q tag to the host.  With Windows unless you have specific drivers doing the marking for you, you will need to do it at the level of the vNIC in UCS.

  Two ways to see this in action.  When you create a service profile in the 'Basic' - not 'Expert' method, you will need to choose a single VLAN for your interfaces.  This will treat interfaces about like an "access Port".  Conversely, when you use the "Expert mode you select the vNIC as a trunk, in which you" will allow to "all VLAN you acceding them as to, like this is the method you did.»

  For a Windows operating system, set the VLAN natively for the VLAN you want to access and you'll be gentle.  Unchecking this option button that "VLAN native" is allowing traffic to cross out of UCS on the VLAN native VLAN 1, your network - it is therefore MAC appears on other fabric under VLAN1

• Can't change phone IP auto macro smartport vlan native on SG200

  We have a few SG200 switches and I try to configure the macros Automatic smartport for the IP phone and IP Phone + Office. Every time I have change the macro and change the VLAN native to what I want (the VLAN voice is OK but not the vlan native, I want desktop computers to connect to), I click on apply, but it automatically changes the VLAN default native VLAN (in our case 1 VLAN). I'm trying to change it to VLAN 2. Any ideas why it won't let me change the VLAN native? I can change the VLAN native on others, such as switches, routers, printers, comments, etc., but not the two above and the desktop as well. These three will not change for some reason any. Thank you!

  Hi Brademeyer29,

  what you see, unfortunately, this isn't a matter of configuration. This was reported to the engineering team and should be fixed in the next firmware version 1.4.1.

  For now, you will have to use the solution as not changing not VLAN native or not use smartport.

  Kind regards

• Question of vlan native

  What is recommended for the vlan native?

  Please let me know if my interpretation of the vlan native is correct.  The vlan native exists only on the ports of junction and isn't the only one vlan tagged across this trunk where all other VLANS on that would be labelled.  No access port on the switch that do not belong to a vlan will have their traffic included in the vlan native and sent through the trunk unidentified.

  I know that the vlan native on a port that has been configured as a trunk by default is vlan 1.  What are the best practices and the reasons why the vlan native should be replaced by something other than vlan1?

  All access ports belong to a virtual local network even if it is only the vlan 1.

  By default the vlan native is also vlan 1, so I can see where you are coming.

  Except that you're right, that the vlan native should be replaced with something else on the switch, mainly because by default, all ports are in the vlan 1 and vlan 1 is also used for other things as well.

  Make the vlan native one vlan unused example. VLAN 999 is a common one.

  There should be no port end assigned in, any SVI (L3 of the interface vlan for it) and you do not need to enable through the trunk or a link.

• How to set the vlan native on a virtual machine in vSphere when you use the 1000V?

  Using the General switch original vSphere, we put VLAN native by VM by setting the VLAN 0 d.

  How do we set VLAN native for a virtual machine, if the virtual computer is connected to a 1000V? I heard that is over, we can use VLAN ID 0?

  Same way as you would on any Cisco switch.

  Add this command to your profile of uplink port:

  switchport trunk vlan native X

  Keep in mind there is no VLAN 0.  VLAN '0' is just how vmware means the VLAN untagged.  There are valid in accordance with the standard 1-4095.

  Kind regards

• Question SG500 auto voice VLAN VLAN native

  I have install SG300 and SG500 switches and using the function of vlan automatic voice by simply changing vlan 100 and using voice of vlan 1 for data and the default value.  I normally put the L3 switch and make a porteach access for my IP PBX (vlan 100) and the other to connect to the existing data network (vlan 1). Then I do a static route in default gateway customers to route to vlan 100 and everything works well for most facilities.

  On my last install, I decided to try to change the vlan 1 default vlan 10 and go with 10 for data and 100 for the voice.  The problem that I ran was that the auto generated on my phone switchports config still serve of vlan 1 vlan native.  I am trying to find a way to always use auto vlan and get the vlan native desired without having to make manual configuration changes.

  Would this be possible?

  Thanks in advance.

  Hi Brandon, you must edit the macro of vlan native 1 to vlan 10.

• New VLAN (wait vlan1 - vlan native) created in 1142N AP does not work

  Hello

  We have put in place which is having vlan existing (100) in local network set in place and even vlan100 is founded in 1142 N but unfortunately I am not able to connect to the existing local-configuration network

  EQ.

  New SSID: Name: wireless

  VLAN 100:

  BVI interface: 10.10.100.2

  I have everything configured correctly in PA but I am not able to reach the default gateway which is router.

  I can't configure new VLANs map with the same ssid vlan?

  only the VLANs native will work fine...

  Light on this please...

  > The default gateway configuration is present on the AP?

  > Whats the switchport configuration? What trunk?

  See the race of the AP and then the switch port configuration, then the configuration of the router interface please

  You will wait for your update...

• Management and Vlan native in different subnet?

  Hello

  As far as I know, the management and the native will be the same... I guess... You have Vlan native as 1 on the switch and Int Vlan 100 on routing switch? Am I wrong? Let me know what are your needs... which will help me to help out you!

  for your question...

  Normally, we specify him vlan native on the switch and the AP so that communication happens... communication won't happen if there is a match of...

  Looking forward to hear from you!

• WLC management port is another trunk that vlan native

  Hello

  I installed my first WLC 5508 with this topology:

  WLC connected trought distribution SFP 1 GB port to the port of switch configured as a Trunk port cut 3 Wireless VLAN:

  -Management WLC, wireless and wireless voice data Vlan (Vlan native is WLAN Management).

  -J' created 2 dynamic interface on WLC on my VLAN Wireless:

  10.7.1.0/24: default management Virtual Interface installing WLC +.

  10.7.6.0/24: Virtual Interface of voice and

  10.7.2.0/24: Wireless Data Interface virtual trought GUI.

  DHCP configured on each dynamic interface is the interface vlan L3 subent for SWITCH main technical IP DHCP Pool equal VLAN.

  WLC management interface IP address is: 10.7.1.10/24

  I create 2 WLAN SSID name with given ID 1, and ID2 voice.

  I create and AP group named APGRP1 that contains the AP recorded about WLC and using the two WLAN SSID.

  The two AP are connected to the switch acess port configured as native management WLC VLAN access port.

  I have to create 3 IP DHCP pool on main switch with the related L3 Interfaces for Inter VLAN routing.

  Problem: when I try to connect from mobile data SSID I get IP address of management WLC VLAN a VLAN data no.

  the same case of Wireless IP Phone configured with voice SSID.

  What I can likely that allows two devices to get the address IP of the correct VLAN?

  Hi Adil,

  T1 > coelio AP on the switch must be configured on a mode of access to the port or trunk mode?

  YEARS - the LWAPP / CAPWAP APs connected to the switchport should be an access port not trunk.

  Q2 > if the first case, the configuration of the port, on the same VLAN as WLC management VLAN support Vlans other WLANS (voice and data)?

  YEARS - Yes it supports, since traffic that involes the WLAN will be inside the tunnel of logic LWAPP/CAPWAP.

  Q3 > I will check the interface between WLAN and dynamic Interfaces map and I'll tell you.

  YEARS - I will wait for your answer!

  Let me know if that answers your question...

• What is AP H-HARVEST of Vlan native?

  We have a few APs - CAP3502 and LAP1242s for most - including H REAP "Vlan native" does not correspond to vlan native of the switchport.  It seems that the vlan native switchport is what gets used to the AP for DHCP (it gets an IP address from the AP of this network).  If so, does anyone know what is the purpose to specify the vlan config REAP H native?  I do not see the usefulness, but if there is one I wish I had someone who could tell.

  Thank you.

  BTW, this is on a 5508 controller running 7.0.240.0 code.

  Yes it's true. It's like if you had two switches with different vlan configured native on the trunk. I see what you're saying, but since I use a lot static address, it makes a difference in my installs. The AP applies only its on the vlan untagged.
