We are just about to start re-addressing our network and at the same time we're looking at breaking the network up into 6 VLAN's and stop using VLAN 1.
Currently on the edge switches we use VLAN 1, 2 (VOICE), 7 (Management) & 50 (Radiology) and originally we were just going to add switchport access vlan x to any ports that don't currently already have a VLAN assigned except for voice. This would mean a manual command entry for each interface.
I remember from a while ago that you can change the Native VLAN so it saves having to enter a command for every interface.
Which is the correct way of doing this manual input or changing the Native VLAN?
If then that you change the native on the uplink and other interfaces are say on vlan 50 but the devices are are not sending tagged traffic will these interfaces get re tagged to the native vlan or willdo as they do now and just use vlan 50?
Another best practice to be sure you are using is to make sure all unused ports are set to access mode and non-negotiate. Another step I take, is to create a local vlan that is not used. Then I assign non-used ports to that vlan and then dis-allow that vlan down any of my trunk ports.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
