8.1 VLAN Policy Overview
A QoS policy can be applied to an interface to regulate the inbound or outbound traffic
on the interface or to a VLAN to regulate the traffic of the VLAN.
A QoS policy applied to an interface is called an interface policy and a QoS policy
applied to a VLAN is called a VLAN policy in this manual.
On C-type and D-type boards, VLAN policies take effect preferentially. That is, if
packets match the VLAN policy, they do not try to match an interface policy; otherwise,
they search an interface policy. On B-type boards, interface policies take effect
preferentially. With an interface policy applied to an interface, the packets do not search
a VLAN policy no matter whether they match the interface policy or not.
VLAN policies are invalid on user authentication interfaces. A user authentication
interface joins and exits a VLAN dynamically, and the corresponding VLAN policy is not
applied to the interface.
VLAN policies are invalid on dynamic VLANs. VLAN policies cannot be applied to
dynamic VLANs. For example, with GARP VLAN registration protocol (GVRP) running,
the switch may create a VLAN dynamically, and the corresponding VLAN policy does
not take effect on the dynamic VLAN.
Note:
The fields in the ACL rules in the QoS policy applied to a VLAN must be a subset of the
fields in the default template. For information about flow templates, refer to ACL
Configuration in the QoS ACL Volume.
