Quality of Service: Managing Bandwidth More Effectively
Differentiated Services Codepoint (DSCP) Mapping
Example of Changing the Priority Setting on a Policy
When One or More Classifiers Are Currently Using the Policy
In this example, the codepoint 000001 is in use by one or more global QoS
policies. If you try to modify the priority currently associated with the code-
point, an error message similar to the following is displayed:
Figure 5-41. Error Message for Changing the Priority on a DSCP Policy
In this case, you would use steps similar to the following to change the priority.
1. Identify the global and classifier-based QoS policies that use the codepoint
whose DSCP-priority mapping you want to change.
Figure 5-42. Identifying the QoS Policies that Use a Codepoint
HP Switch(config)# qos dscp-map 1 priority 2
Cannot modify DSCP Policy 1 - in use by other qos rules.
HP Switch(config)# show qos device-priority

802.1s Multiple Spanning Tree Protocol (MSTP)

Describes MSTP's use of VLANs to create multiple spanning trees for improved utilization.

Configuring MSTP

Outlines prerequisites and settings for configuring MSTP globally, per port, and per instance.

Troubleshooting an MSTP Configuration

Explains how to use `show spanning-tree` commands for monitoring, troubleshooting, and debugging MSTP.

Loop Protection

Discusses loop protection as an alternative to STP for preventing loops at the network edge.

Stack Management for the 3500, 3500yl, 6200yl and 6600 Switches

Details how to view stacking data for individual switches or all switches in the subnet.

QinQ (Provider Bridging)

Features and Benefits

Lists advantages of QinQ, including increased VLAN space and customer traffic isolation.

Enabling QinQ and Configuring QinQ Modes

Explains how to enable QinQ and the supported modes: mixed VLAN and VLAN only.

Configuring QinQ

Outlines general steps for configuring QinQ, including S-VLANs and port types.

Configuring Per-Port S-VLAN Membership

Details how to use `svlan` commands for tagged and untagged per-port S-VLAN memberships.

Classifier-Based Software Configuration

Traffic Classes

Introduces classifier features, additional policy actions, and configuration of service policies.

Creating a Traffic Class

Explains how to use `match` and `ignore` commands to create classes of IPv4 or IPv6 traffic.

Creating a Service Policy

Details how to create QoS, mirroring, or PBR policies by defining actions for traffic classes.

Applying a Service Policy to an Interface

Describes how to apply QoS, mirroring, or PBR policies to inbound traffic on ports or VLAN interfaces.

Zone Classes

Explains zone classes used with Transparent Mode for intercepting and redirecting packets to ONE applications.

Creating a Zone Class

Details how to create a zone class using the `class zone` command and `port-list` command.

Creating a Zone Policy

Explains how to configure zone policies by defining intercept rules for source and destination zones.
