CAUTION: Follow these rules when configuring a behavior. Otherwise the
corresponding QoS policy cannot be applied successfully.
The action of creating an outer VLAN tag cannot be configured simultaneously
■
with any other action except the traffic filtering action or the action of setting
802.1p precedence in the same traffic behavior. The action of creating an outer
VLAN tag must be applied to basic QinQ-enabled ports or port groups.
When the action of setting the service provider network VLAN ID is applied in
■
the inbound direction, any other action except the traffic filtering action or the
action of setting 802.1p precedence cannot be configured in the same traffic
behavior.
When the action of mirroring traffic is applied in the outbound direction, any
■
other action cannot be configured in the same traffic behavior.
Configuration example
1 Network requirements
Configure a policy named test to associate the traffic behavior named
test_behavior with the class named test_class. Apply the policy to the inbound
direction of GigabitEthernet 1/0/1 port.
