Operation Manual – QoS
H3C S7500E Series Ethernet Switches
Caution:
To ensure that a QoS policy can be applied successfully, follow these guidelines when
configuring a behavior for the policy:
The action of creating an outer VLAN tag cannot be configured with any other action
at the same time 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.
You can apply a QoS policy in the outbound direction of a basic QinQ-enabled port
on an SA LPU or EA LPU to implement one-to-one VLAN mapping. In this policy,
only one matching rule, if-match service-vlan-id, can be defined, and the action
can only be remark customer-vlan-id or remark customer-vlan-id together with
remark dot1p.
IV. Configuration example
1) Network requirements
Configure a QoS policy test_policy. Associate the traffic behavior test_behavior with
the traffic class test_class in the policy, and apply the policy to:
the inbound direction of Ethernet 2/0/1.
the inbound direction of VLAN 200, VLAN 300, VLAN 400, VLAN 500, VLAN 600,
VLAN 700, VLAN 800, and VLAN 900.
the inbound direction globally.
2) Configuration procedure
# Enter system view.
<Sysname> system-view
# Create a policy (This operation leads you to policy view).
[Sysname] qos policy test_policy
[Sysname-qospolicy-test_policy]
# Associate the traffic behavior test_behavior with the class test_class.
[Sysname-qospolicy-test_policy] classifier test_class behavior test_behavior
[Sysname-qospolicy-test_policy] quit
# Apply the QoS policy to the inbound direction of Ethernet 2/0/1.
