Enabling Port-Based Or Vlan-Based Qos; Configuring The Trust State Of A Port - Cisco WS-X6066-SLB-APC - Content Switching Module Software Manual

Configuring QoS

Enabling Port-Based or VLAN-Based QoS

The commands in this section are not supported with a Layer 2 Switching Engine.
Note
By default, QoS uses ACLs attached to ports. On a per-port basis, you can configure QoS to use ACLs
attached to a VLAN. To enable VLAN-based QoS on a port, perform this task in privileged mode:
Task
Step 1 Enable VLAN-based QoS on a port.
Step 2
Verify the configuration.
For more information, see the
This example shows how to enable VLAN-based QoS on a port:
Console> (enable) set port qos 1/1-2 vlan-based
Hardware programming in progress...
QoS interface is set to vlan-based for ports 1/1-2.
Console> (enable)
Changing a port from port-based to VLAN-based QoS detaches all ACLs from the port. Any ACLs
attached to the VLAN apply to the port immediately (for more information, see the
Interfaces" section on page

Configuring the Trust State of a Port

This command configures the trust state of a port (for more information, see the
Marking, Scheduling, Congestion Avoidance, and Classification" section on page
ports are untrusted.
To configure the trust state of a port, perform this task in privileged mode:
Task
Step 1 Configure the trust state of a port.
Step 2 Verify the configuration.

The trust-ipprec and trust-dscp keywords are supported only with a Layer 3 switching engine.
1q4t ports (except Gigabit Ethernet) do not support the trust-ipprec and trust-dscp port keywords.
You must configure a trust-ipprec or trust-dscp ACL that matches the ingress traffic to apply the
trust-ipprec or trust-dscp trust state.
On 1q4t ports (except Gigabit Ethernet), the trust-cos port keyword displays an error message,
activates receive-queue drop thresholds, and—as indicated by the error message—does not apply the
trust-cos trust state to traffic. You must configure a trust-cos ACL that matches the ingress traffic
to apply the trust-cos trust state.
