Setting all ports to trunk on Cisco Switch

[John Mink]

I'm experimenting with VLAN tagging at the server level. One thing I was curious about was setting all ports on a switch to a TRUNK port to allow the server to designate which Tag to assign to the packet. When I do this no VLAN will come up unless I switch a port to an ACCESS VLAN then switch it back to a trunk port after it comes up. This keeps the VLAN up, but I'm worried about switch reboots and what not. This means I have to do that every time the switch reboots. Is there a reason people do not do this and just limit traffic based on pruning rules? Or is there a better way of doing this?

It is common to have the ports connecting to VM environments in trunk mode as there are usually multiple vlans involved. Once the changes are made and the ports are configured as trunks and you save the config reboot should not change anything and the ports should still be in trunk mode.
