I am trying to determine whether a switchport can be configured for access to say vlan 10 and vlan 20 but not be a trunk port. I was told that this could be used for configuring security through a new proposed vlan project but... If anyone has any knowledge about configuring vlan security and/or the port issue that would be great! Thanks
This is not a supported feature on switches. Some old XL switches do support this feature but that is taken off on all new switches and releases.
