Good morning, question about a native vlan.
I set up a trunk with two vlans I created - vlan 100 and vlan 10. vlan 1 is shut down. I was reading about dot1q native vlan being the vlan where untagged frames are sent. My question is is vlan 1 always the native vlan? Is dot1q going to choose 10 or 100 to be my native vlan or do I have to specify which is my native vlan? If left unspecified, which one is my native vlan? Can I make both vlans tag traffic?
The switch is a 2960

Hi,
There is only one native vlan on a switch and by default it is vlan 1. you can change it indeed on a trunk port with the command
switchport trunk native vlan ( but don't forget it must be the same on both ends of the trunk)
If you don't change it then it will be vlan 1 and both your vlans 10 and 100 will be tagged when going over a trunk link.
Rregards.
