Hi


The x can be any vlan number yes but if you are specifying a particular vlan number make sure it is the same on both ends of the link.


You are correct in that the native vlan is the vlan that is not tagged across an 802.1q trunk.


HTH

no it doesn't matter as long as it matches the switch native on the other end .

Glen is correct, matching vlans at each end only matters if the vlan spans the intermediate switch as this could cause routing loops.


I am just trying to get this straight in my head! We have to specify a vlan number but it can be any number because it has absolutely NO effect whatsoever, weird!

It is best to use some kind of scheme though to your addressing say the subnet is like 192.168.85.0 , it would be a lot easier to remember and troubleshoot if you made the vlan number like vlan 85 . Just makes it easier if there is some kind of commonality between the vlan number and the subnet number . If you are only dealing with a few vlans then it probably doesn't matter.
