WS-C3750X-48T-L and tag native vlan

[cisco-lix]

Hi guys,

I have recently bought a new cisco switch : WS-C3750X-48T-L

Switch Ports Model              SW Version            SW Image                 
------ ----- -----              ----------            ----------               
*    1 54    WS-C3750X-48       12.2(55)SE5           C3750E-UNIVERSALK9-M

with this licence :

Index 1 Feature: ipservices     
    Period left: 8  weeks 4  days
    License Type: Evaluation
    License State: Active, Not in Use, EULA not accepted
    License Priority: None
    License Count: Non-Counted

Index 2 Feature: ipbase         
    Period left: 0  minute  0  second  
Index 3 Feature: lanbase        
    Period left: Life time
    License Type: Permanent
    License State: Active, In Use
    License Priority: Medium
    License Count: Non-Counted

I want to tag all native vlan traffic from this switch with the command :

vlan dot1q tag native.

I can't see this command on the command line interface. How can I reach this option ?

Have I to pay something ?

Thanks for your answers.

The correct interface-level command is:  switchport trunk native vlan XYZ

My english is not that good so maybe I wasn't clear.

This command is for define a native vlan. I want all the traffic to be tagged. According to this thread https://supportforums.cisco.com/discussion/11823136/native-vlan-tagging I found that it's possible. I just want to know if my switch can do that and how to find this command.

Regards.

Hi.

Catalyst 3750 Software Configuration Guide, Release 12.2(55)SE:

Switch(config)# vlan dot1q tag native

Switch# show vlan dot1q tag native
dot1q native vlan tagging is enabled

You can also configure your port using

Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport trunk allowed vlan 100 !-- configure only your VLAN

In this case all untagged frames and frames with a different VLAN ID are dropped.

Regards.

The Software Configuration Guide gives some command line but in my switch i can't see vlan dot1q ...

The only vlsn options I've got is :

switch#show vlan ?
  brief        VTP all VLAN status in brief
  group        VLAN group(s) information
  id           VTP VLAN status by VLAN id
  ifindex      SNMP ifIndex
  internal     VLAN internal usage
  mtu          VLAN MTU information
  name         VTP VLAN status by VLAN name
  remote-span  Remote SPAN VLANs
  summary      VLAN summary information
  |            Output modifiers
  <cr>

or

swicth(config)#vlan ?
  WORD        ISL VLAN IDs 1-4094
  access-map  Create vlan access-map or enter vlan access-map command mode
  filter      Apply a VLAN Map
  group       Create a vlan group
  internal    internal VLAN

Nothing about vlan dot1q tag native ...

Probably is a license limitation: "Each Cisco Catalyst 3750-E/3560-E or 3750-X/3560-X system is loaded with a universal Cisco IOS® Software image. Universal Cisco IOS Software images contain all Cisco IOS Software features. The level of Cisco IOS Software functionality available is determined by the combination of one (or more) licenses installed on the device."

Ok. Thanks for your help.

Do you know where I can find the lanbase features list ? As I know, tagging native vlan is included in the lanbase licence.
