Restrictions for QoS: Enhanced Show Commands for Active Policies

For ATM permanent virtual circuits (PVCs), policy maps do not remain associated with the interface if the ATM PVC is not working properly (that is, the ATM PVC is "down"). Therefore, if an ATM PVC is down, and a policy map is attached to an interface, the show policy-map interface brief command does not include information about the policy maps in the command output.

Information About QoS: Enhanced Show Commands for Active Policies

To use the QoS: Enhanced Show Commands for Active Policies feature, you should understand the following concepts:

•Benefits of the Enhanced Show Commands

•Time-stamp and User ID Information in the Enhanced Show Commands

•VPN Information in the Enhanced Show Commands

Benefits of the Enhanced Show Commands

Fine-Tune Information Reported

The QoS: Enhanced Show Commands for Active Policies feature introduces the show policy-map interface brief command. The keywords and arguments of the show policy-map interface brief command allow you to tailor and fine-tune the information displayed by the command so that only the active policies (that is, those policy maps attached to an interface) are displayed.

Time-stamp and User ID Information Reported

The show policy-map interface brief command also provides the time stamp (that is, the date and time) when the policy map was attached to an interface, along with the user ID of the person who attached the policy map to the interface.

VRF Interface Information Reported

The show policy-map interface brief command displays the active policies attached to an interface. If you are using a virtual private network (VPN), the show policy-map interface brief command displays the active policies attached to VRF interfaces that are used in a VPN.

Time-stamp and User ID Information in the Enhanced Show Commands

The keywords and arguments included with the show policy-map interface brief command allow you to fine-tune the information that the command displays.

For example, if you use the optional timestamp keyword, the time and date that a policy map was attached to an interface will be included in the display. In addition to the time and date information, the name (that is, the user ID) of the person who attached the policy map to the interface will also be displayed.

---

Note If the network software is reloaded (reinstalled), the timestamp information (the time and date information) obtained will not be retained for any of the policy maps attached to interfaces on the network. Instead, the time and date information displayed will be the time and date when the software was reloaded.

---

How the User Information is Obtained

The user information included in the display is obtained from the information you enter when you log on to the router. For example, if you are using the SSH Secure Shell utility to log on to a router, you would typically enter your username and password.

However, it is not always possible to obtain the user information. Instances where user information cannot be obtained include the following:

•Not all routers require user information when you log on. Therefore, you may not be prompted to enter your username when you log on to a router.

•If you are connecting to a console port using the telnet utility in a DOS environment, you do not need to enter user information.

•The user information cannot be retrieved due to system constraints or other reasons.

If the user information cannot be obtained, the words "by unknown" will be displayed as shown below.

Service-policy output: policyname2

VRFB   interface s6/0/1 - applied 21:47:04 on 23/12/01 by unknown

VPN Information in the Enhanced Show Commands

The show policy-map interface brief command includes an optional keyword, vrf, and associated argument, vrf-id, that can be used with VPNs.

When you use the vrf keyword and the vrf-id argument, the display includes information about the VRF interface.

Service-policy input: policyname1

VRFA   interface s2/0/1 

VRFB   interface s6/0/0 

How to Use the QoS: Enhanced Show Commands for Active Policies Feature

The QoS: Enhanced Show Commands for Active Policies feature introduces the show policy-map interface brief command. This section contains the procedure for using the show policy map interface brief command.

•Using the show policy-map interface brief Command

Using the show policy-map interface brief Command

Use the keywords and arguments of the show policy-map interface brief command to display only the active policy maps, along with information about the interfaces to which the active policy maps are attached.

To use the show policy map-interface brief command, complete the following steps.

Prerequisites

Policies (that is, policy maps) must exist and must be attached to an interface for the results of the display to be useful. Therefore, before using the show policy-map interface brief command, use the Modular Quality of Service (QoS) Command-Line Interface (CLI) (MQC) to create and configure your policy maps as appropriate, and attach the policy maps to interfaces.

SUMMARY STEPS

1. enable

2. show policy-map interface [input | output] brief [policymap-name] [vrf [vrf-id]] [timestamp]

3. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	show policy-map interface [input | output] brief [policymap-name] [vrf [vrf-id]] [timestamp] Example: Router# show policy-map interface input brief policy_map_1 timestamp	Displays information about the active policy maps. •Enter any optional keywords or arguments.
Step 3	exit Example: Router# exit	(Optional) Exits privileged EXEC mode.

Examples

The information that is displayed by the show policy-map interface brief command varies according to the optional keywords and arguments that you specify.

If you do not specify any optional keywords or variables, all policy maps are displayed.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.2(28)SB	This command was introduced.

Usage Guidelines

The show policy-map interface brief command displays the name of the active policy maps and the interfaces to which those policy maps are attached. An active policy map is one that is attached to an interface.

The optional keywords and arguments allow you to tailor the information displayed about VPNs, time stamps, and user IDs.

If you do not specify any optional keywords or arguments, all policy maps (even those that are not active) are displayed.

VPN Information Reported

The show policy-map interface brief command can be used for VRF interfaces in applications that use virtual private networks (VPNs). To specify VRF interfaces, use the vrf keyword with the vrf-id argument.

Time-stamp and User ID Information Reported

If the optional timestamp keyword is used with show policy-map interface brief command, the time and date when when a policy map was attached to an interface appear in the display. In addition to the time and date information, the name (that is, the user ID) of the person who attached the policy map to the interface will also be displayed.

---

Note If the network software is reloaded (reinstalled), the timestamp information (the time and date information) obtained will not be retained for any of the policy maps attached to interfaces on the network. Instead, the time and date information displayed will be the time and date when the software was reloaded.

---

Method for Obtaining User Information

The user information included in the display is obtained from the information that you enter when you log in to the router. For example, if you are using the SSH Secure Shell utility to log in to a router, you would typically enter your username and password. However, it is not always possible to obtain the user information. Instances where user information cannot be obtained include the following:

•Not all routers require user information when you log in. Therefore, you may not be prompted to enter your username when you log in to a router.

•If you are connecting to a console port using the Telnet utility in a DOS environment, you do not need to enter user information.

•The user information cannot be retrieved because of system constraints or other factors.

If the user information cannot be obtained, the words "by unknown" will be displayed.

Hierarchical Policy Map Information

For a hierarchical policy map structure, only the information about the parent policy maps is displayed. Information about child policy maps is not displayed.

ATM PVCs

For ATM permanent virtual circuits (PVCs), policy maps do not remain associated with the interface if the ATM PVC is not working properly (that is, the ATM PVC is "down"). Therefore, if an ATM PVC is down, and a policy map is attached to an interface, the show policy-map interface brief command does not include information about the policy maps in the command output.

In some network configurations, the policy map may be attached to the interface initially, and then at a later time, the interface can be configured to act as a VRF interface. In this kind of network configuration, the time-stamp information displays the time when the policy map was attached to the interface. The display does not include the time when the interface was configured to act as a VRF interface. Displaying only the time when the policy map is attached to the interface also applies to the scenarios described below.

In other network configurations, a VRF may be attached to multiple interfaces as described in the following scenarios:

•The policy map is also attached to both the interfaces and the VRFs. In this network configuration, all the interfaces should be shown in the display for the VRF, under the policy map name, as follows:

Service-policy input: policyname1

VRF1 interface s2/0/1 - applied 21:47:37 on 23/12/01 by JBloggs

     interface atm0/0 - applied 11:37:57 on 21/11/01 by JBloggs

•The policy map is not attached to all interfaces to which the specific VRF is attached. In this network configuration, only the VRF interfaces that have that policy map configured are displayed.

Glossary

MQC—Modular Quality of Service Command-Line Interface. A command-line method used to create and configure class maps and policy maps, and then attach the policy maps to interfaces. The MQC is used to apply many QoS features, such as network traffic classification and marking, to a network.

policy map—A configuration file that applies one or more QoS features to a specific class or category of traffic. Policy maps are often referred to as service polices, as the Cisco IOS service policy command is used to attach a policy map to an interface.

VPN—Virtual Private Network. Enables IP traffic to travel securely over a public TCP/IP network by encrypting all traffic from one network to another. A VPN uses "tunneling" to encrypt all information at the IP level.

VRF—A VPN routing/forwarding instance. A VRF consists of an IP routing table, a derived forwarding table, a set of interfaces that use the forwarding table, and a set of rules and routing protocols that determine what goes into the forwarding table. In general, a VRF includes the routing information that defines a customer VPN site that is attached to a router.
