vlan hopping

How may I force a Netvanta 1638p to tag the native VLAN on all its 802.1Q trunks ?

Re: vlan hopping

David,

    The following will set a port to untagged access on vlan 100.   Let me know if this is what you had in mind.

interface switchport 0/1

  description Tagged One VLAN

  no shutdown

  switchport access vlan 100

Re: vlan hopping

David,

This is how you configure an 802.1Q trunk with a specific native VLAN.  By default, the native VLAN ID is 1.  If you need another VLAN set for untagged traffic, you need to specify the native VLAN ID.

interface switchport 0/1

switchport mode trunk

switchport trunk native vlan 100

no shutdown

This will allow the port to be an 802.1Q trunk, but pass untagged traffic to a specific VLAN.

I hope this helps.
