Configuration Output Customization Overview

You can customize the configuration information by including or excluding lines of output based on the keywords described in this section.

Using a keyword with the show configuration command might be more effective than using show configuration | begin. When show configuration is used with a specific keyword, the current configuration is quickly determined and displayed for only that specified keyword. Executing show configuration | begin causes all output of show configuration to be generated, but the output is not displayed until the begin criterion is met.

Use the virtual-router keyword to display the current configuration of a specified virtual router. You can combine the virtual-router keyword with the category keyword to display the current configuration of specific settings for a virtual router.

Use the interface keyword to display the current configuration of a particular interface. Use the type keyword to target specific interface types. You can exclude information about particular types of interfaces using the exclude-category interface keyword.

Use the category keyword to display the current configuration of a specific group of router settings. The settings are organized in categories by function.

Use the tag-group keyword with the category interfaces keywords to tag interfaces as belonging to a specific group and display all interfaces within a group.

Use the tag-group command to configure an interface tag group. Any number of interfaces can be in a tag group. The following interface types cannot be added to tag groups: tunnel, lag, mlppp, and mlframe-relay. An interface can be in only one tag group.

Table 32 describes the categories of router settings and the type of information displayed for each category.

Table 32: Categories of Router Settings

Category

Configuration Displayed

aaa

Authentication, authorization, and accounting (AAA) settings, such as the default authentication protocol and the RADIUS accounting server

address-assignment

Address assignment settings for Dynamic Host Configuration Protocol (DHCP) and the local address server

flow-management

Flow management settings, such as firewalls, Network Address Translation (NAT), and IP flow statistics

interfaces

Physical interfaces (types and specifiers); this is the only category that displays information about interfaces

ip-protocols

Internet protocols, such as Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF)

link-layer-forwarding

Link-layer settings, such as bridged interfaces and link-layer interface types

management

Router management settings, such as the command-line interface (CLI), bulk statistics, and Telnet

physical-layer-protocols

Physical layer protocols, such as DS1, DS3, and SONET/SDH

policy

Policy settings, such as policy lists, classifier groups, and rate-limit profiles

qos

Quality of service (QoS) settings, such as traffic class, drop profile, and scheduler profile

system

System-level settings, such as timing, logging, and redundancy

tunneling

Tunneling protocols, such as IP Security (IPsec), Multiprotocol Label Switching (MPLS), and Layer Two Tunneling Protocol (L2TP)

Many of the categories described in Table 32 contain subcategories of router settings. For example, you can specify show configuration category management cli to display only the configuration for the CLI. To display the names of subcategories that you can specify for each category, issue the show configuration category categoryName ? command.

Note: When you specify categories with the show configuration command, the output might display additional configuration data that is not explicitly associated with the categories that you specified.
