VLAN-ACL Configuration

newly added one. However, if the port delete the self-defined flow template, 
the system will apply QACL rules in the VLAN to the new port automatically.
You will fail to change the flow template applied to a port with a VLAN-ACL 
already applied to a customized flow template.
If both a VLAN and one of its ports have QACL rules applied, only those applied to 
the port work. In this case, the VLAN-ACL takes effect only after the QACL rules 
and the self-defined flow template on the port are deleted.
When the VLAN contains no ports, the system is prohibited from applying 
VLAN-ACL (including adding and deleting rules).
Two ports differing in VLAN-ACL configuration cannot be aggregated dynamically.
A VLAN-ACL is prohibited from being applied to a VLAN containing intermixing 
ports. Similarly, a VLAN with a VLAN-ACL applied to is prohibited from being used 
for MPLS intermixing.
CAUTION: VLAN-ACL does not take effect on the ports of the XP4 card.
