QoS Support for Additional Devices

QPM 2.1.1 provides support for the following additional devices:

The following sections describe the new features supported on Catalyst 4000 Layer 2 devices and Catalyst 6000 devices with PFC2.

CoS Mapping and Default CoS on Catalyst 4000 Layer 2

On Catalyst 4000 Layer 2 switches, QPM 2.1.1 allows you to:

  • Map CoS values to transmit queues—This feature applies to 2q1t queuing. Each pair of CoS values is associated with either queue 1 or queue 2.

  • Configure the default CoS value for the switch—This default value will be assigned to any unclassified frames received on any port on the switch.

Access these features as follows:

1. In the Device Properties dialog box for the switch, click QoS Property.

2. In the displayed Properties of Cat4000 Queuing dialog box, select the Enable Custom CoS Mapping check box.

3. CoS Mapping: For each pair of CoS values, select the queue to which packets with those CoS values will be directed.

4. Default CoS Value: In the Default CoS Value field, select the required value from the dropdown list.

5. Click OK to return to the Device Properties dialog box.

Dual-Rate Aggregate Limiting on Catalyst 6000 with PFC2

On Catalyst 6000 devices with PFC2, you can create a dual-rate aggregate limiting (policing) rule with a normal rate and an excess rate.

The parameters that can be defined for an aggregate limiting policy (or a cross-interface aggregate limiting policy on a device group) are the same as for the Catalyst 6000 device, with the following additions:

  • Excess Rate—The maximum rate for traffic that is in excess of the normal rate.

  • Violate Action—The action to be performed for traffic that exceeds the Excess Rate, either none, markdown or drop. If the action is markdown, you can define the markdown values in the Excess Rate tab in the DSCP Markdown Table, accessed from the Device Properties window. If you do not define these values, the default values will be used.


  • Note   For Catalyst 6000 PFC2 devices running IOS, the Violate Action cannot be less severe than the Exceed Action.


    Note   For Catalyst 6000 PFC2 devices running CatOS, if the Excess Rate and Violate Action parameters are used, the Exceed Action will always be Markdown (policed-dscp).

New Features

QPM 2.1.1 provides the following new features:

New and Modified Voice Templates

New voice templates have been added to the IP_Telephony_Template database, and some existing voice templates have been changed, to provide improved support for QoS configuration for IP telephony networks.


Note   After you install the patch, you need to make sure that your voice templates are up to date in all relevant databases. To copy the new and updated templates to your databases, open the IP_Telephony_Template database and follow the procedure in Copying All Device Groups in a Database to Other Databases.

Catalyst 6000 Switches with a PFC2 Card

The following new voice templates have been added for ports on Catalyst 6000 switches with a PFC2 card:

IP Phone Ports
  • AccPFC2=>IP-Phones—This device group has the same properties and policies as the Acc6000=>IP-Phones, except for the model, which is Cat6000(PFC2).

  • AccDistPFC2VoiceVLAN—This device group has the same properties and policies as the AccDist6K-VoiceVLAN, except for the model, which is Cat6000(PFC2).

SoftPhone Ports
  • AccPFC2=>SoftPhones—This device group has the same properties and policies as the Acc6000=>SoftPhones, except for the model, which is Cat6000(PFC2).

Modified Templates

  • The WAN-PPP-High(>768k) template has been renamed and is now the WAN-HDLC-High(>768k) template.

Per Device Scheduling

QoS scheduling properties and CoS to DSCP mapping for Catalyst switches are configured on a device basis, and therefore cannot be included in the QoS templates. These QoS properties are set automatically by QPM when the device is added to the IP Telephony QoS database.

The following properties have been added for the Catalyst 4000 devices:

  • All traffic with CoS values of 3 through 7 are placed in queue number 2, which is the highest priority queue.


  • Note   For more information about the QPM voice templates, see the user guide for QoS Policy Manager 2.1, Chapter 9, Configuring QoS for IP Telephony.

Cross-Database Duplication of New or Updated Device Groups

This feature enables you to copy device groups from one QPM database to other QPM databases. In addition, if you have the same device group in several databases, you can update the device group once, and then apply your updates in all other databases in which the device group is present.


Note   In the QPM 2.1.1 patch, new IP telephony templates have been added and some existing templates have been modified. Therefore, after you install the patch, you are recommended to use this feature to make sure that your voice templates are up-to-date in all the relevant databases.

Copying a New or Updated Device Group to Other Databases

After you have created a new device group in one database, you can copy the device group (including its name, QoS properties and QoS policies) to other databases. You can also copy updates you have made to an existing device group to the same device group in other databases, as long as the device group has the identical name and constraints (device model, software version, interface type, card type, interfaces/sub-interfaces and QoS property).


Note   Device groups with policies that use application services or host groups in their filters, cannot be added or updated to other databases.

Procedure

1. Right-click on the device group in the tree view pane or select Devices>Device Groups.

2. Select the relevant option, either Add Device Group to Other Databases or Update Device Group In Other Databases. A message is displayed requesting confirmation of this action for each of your existing databases in turn.

3. Click Yes to confirm that you want to add the selected device group to the specified database. Click Yes to All to add the device group to all your databases.


Note   If you are adding a device group to other databases and a device group with the same name exists in any of the databases, the device group will not be copied to that database and you will receive a message informing you of this.


Note   QPM 2.1.1 cannot read databases from previous QPM versions. If any of your target databases is from an older version, you will be prompted to upgrade the database, otherwise the device group will not be added/updated to that database.

Copying All Device Groups in a Database to Other Databases

You can copy all the device groups in a database to other databases. All new device groups will be added to other databases as long as no device group with the same name exists in the other databases. Modifications made to device groups will be copied to device groups with the identical name and constraints in other databases.


Note   Device groups with policies that use application services or host groups in their filters, cannot be added or updated to other databases.

Procedure

1. Right-click anywhere in the tree view pane or select Devices>Device Groups.

2. Select the relevant option, either Add All Device Groups To Other Databases or Update All Device Groups In Other Databases. A message is displayed requesting confirmation of this action for each of your existing databases in turn.

3. Click Yes to confirm that you want to add all the device groups to the specified database. Click Yes to All to add all the device groups to all your databases.

Restoring the Previous Database Version

When you add/update device groups in other databases, QPM makes a backup copy of each database before it is changed by your action. This backup file is located in the Database directory under the QPM root directory (for example, new_database.epd.bak).

To go back to the previous version of a database, delete the current .epd file and rename the .epd.bak file.

Microflow and Aggregate/Cross-Interface Aggregate Limiting on the Same ACL on Catalyst 6000 Devices Running CatOS

On Catalyst 6000 devices, you can define a single limiting policy, with a single filter, that includes both microflow and aggregate limiting (or cross-interface aggregate limiting for device groups).

The Limiting page of the Policy Wizard provides two columns of fields, one for microflow limiting and one for aggregate limiting. Select the check box(es) at the top of the column(s) to enable the fields, and fill in the values accordingly.


Note   You can define cross-interface aggregate limiting on device groups by selecting Cross-Int Aggregate in the Limiting Type field.

Default ACL on Catalyst 6000 Devices (CatOS)

You can define a default ACL on a Catalyst 6000 device running CatOS, to be used for traffic that does not match any named ACL on the device. You can color this traffic with a DSCP value, or you can trust it by CoS, DSCP or IP Precedence.

To use this feature:

1. Click the Default ACL button in the Device Properties dialog box.

2. Select the Enable Default ACL check box.

3. Select the action to be performed on the traffic.

4. Click OK to return to the Device Properties dialog box.

Support for Import of RME Version 2 Device Inventory Files

QPM now supports the import of CSV or DIF Version 2.0 files from RME.

Resolved Problems

The QPM 2.1.1 patch resolved the following problems, that existed in QPM 2.1.


Table 1: QPM 2.1.1 Resolved Problems
Bug ID Summary Additional Information

CSCdu57179

If the QoS property on a Catalyst 6000 (IOS) device was changed to Do Not Change, QPM only removed the policies on the current interface, and did not remove the policies on the rest of the interfaces in the ASIC group.

QPM now removes all policies on all the interfaces in the ASIC group, if the QoS property is changed to Do Not Change, since the policies are no longer valid.

CSCdu36423

QPM did not recognize PBR coloring policy on a subinterface without FRTS.

You no longer need to configure FRTS on the subinterface or upgrade the IOS software on the device to a version that supports CAR coloring (IOS 12.0 and higher) to work around this problem.

CSCdu39495

FRF bandwidth percentage was calculated according to interface rate and not minCIR.

You can now leave the Minimum Rate field in the Interface Properties dialog box blank if you want to use the default minCIR value.

CSCdu39627

QPM uploaded trust policies on Catalyst 6000(IOS) with Trust CoS, even if the policies specified Trust DSCP or Trust IP Precedence.

None.

CSCdu39744

QPM deployed adjusted rate values for limiting policies on Catalyst 4000-L3 devices

None.

CSCdu39761

Duplicate class-map naming on device groups with FRTS and Class Based QoS.

You can now define policies with different directions on this device group.

CSCdu40749

QPM did not upload dFRF on a 7500 VIP device with 12.1(6)E and CBWFQ.

None.

Bug ID Summary Explanation

CSCdu72386

Access Violation error when saving a DB with Cat8K device.

Attempts to save a database that contains a Catalyst 8500 device may be unsuccessful and the policy configurations in that database may be lost.

Workaround: Save Catalyst 8500 devices in a separate database.

CSCdv20264

Deploy error on Cat6K-IOS/PFC2 DGs with QoS property "Defined by Interface."

If the QoS Property for Catalyst 6000 (IOS) or Catalyst 6000 (PFC2-IOS) device groups is Defined by Interface and you edit a policy and redeploy, the deployment fails.

Workaround: Do not use Defined by Interface as the QoS Property for these device groups.

CSCdv29919

Cat6K-NoPFC upload doesn't show Trust state.

Uploading the device configuration does not work on Catalyst 6000 devices without PFC.

Workaround: Define the device configuration manually.

CSCdv29924
