the VLAN interface configuration mode can only be disabled in the VLAN interface mode.
 When a physical interface is added into or removed from a VLAN (with the trunk interfaces as
exceptions), ACL configured in the corresponding VLAN will be bound or unbound respectively. If ACL
configured in the target VLAN, which is configured in VLAN interface mode, conflicts with existing ACL
configuration on the interface, which is configured in physical interface mode, the configuration will fail
to effect.
 When no physical interfaces are configured in the VLAN, the ACL configuration of the VLAN will be
removed. And it can not recover if new interfaces are added to the VLAN.
 When the interface mode is changed from access mode to trunk mode, the ACL configured in VLAN
interface mode which is bound to physical interface will be removed. And when the interface mode is
changed from trunk mode to access mode, ACL configured in VLAN1 interface mode will be bound to
the physical interface. If binding fails, the changing will fail either.
 When removing a VLAN configuration, if there are any ACLs bound to the VLAN, the ACL will be
removed from all the physical interfaces belonging to the VLAN, and it will be bound to VLAN 1 ACL(if
ACL is configured in VLAN1). If VLAN 1 ACL binding fails, the VLAN removal operation will fail..
