on a 2950 and above maybe some lower.. if you go in config and enter this on a interface
switchport access vlan 300
however my switch was not configured for vlan 300 it creates a vlan 300 container on the fly. i want to know is there a way to turn that off.. in case someone typos the wrong vlan, next thing i know i have switches with vlans configured that should'nt have them..??
i want to be forced to create the vlan first in config mode not in interface config mode.
