Chapter 5 CLI Tips, Techniques, and Shortcuts

Viewing System Information with show Commands

•If the saved output is to be used as a configuration file, the filename should end with the cfg suffix for easy identification. This suffix is not required, but can help locate target configuration files. Example: myconfig.cfg

In the following example, a target configuration file is saved to the default user directory:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# show configure file disk0:myconfig.cfg

RP/0/RSP0/CPU0:router(config)# abort

RP/0/RSP0/CPU0:router#

Narrowing Output from Large Configurations

Viewing a large running configuration can produce thousands of lines of output. To limit the output of a show command to only the items you want to view, use the procedures in the following sections:

•Limiting show Command Output to a Specific Feature or Interface, page 5-8

•Using Wildcards to Display All Instances of an Interface, page 5-8

Limiting show Command Output to a Specific Feature or Interface

Entering keywords and arguments in the show command limits the show output to a specific feature or interface.

In the following example, only information about the static IP route configuration appears:

RP/0/RSP1/CPU0:router# show running-config router static

router static address-family ipv4 unicast

0.0.0.0/0 10.21.0.1

0.0.0.0/0 Gi0/1/0/1 10.21.0.1

!

!

In the following example, the configuration for a specific interface appears:

RP/0/RSP0/CPU0:router# show running-config interface Gi 0/1/0/1

interface Gi0/1/0/1

ipv4 address 10.21.54.31 255.255.0.0

!

Using Wildcards to Display All Instances of an Interface

To display the configuration for all instances, type the asterisk (*) wildcard character.

Note See the “Using Wildcards to Identify Interfaces in show Commands” section on page 5-12for more information.

In the following example, a configuration for all Gigabit-Ethernet interfaces appears:

RP/0/RSP1/CPU0:router# show running-config interface gi *

interface Gi0/1/0/0

ipv4 address 10.2.3.4 255.255.255.0 gi

A9KMOD80TR, A9K24X10GETR, ASR 9000 specifications

Cisco Systems has long been a leader in networking technology, providing cutting-edge solutions for service providers and enterprise organizations alike. Among their standout products is the Cisco ASR 9000 Series Aggregation Services Routers, notably the A9K24X10GETR and the A9KMOD80TR models. These routers are engineered to deliver unmatched performance, scalability, and versatility for networks that require high bandwidth and low latency.

The Cisco ASR 9000 Series is built for the needs of today's complex service provider and enterprise networks. A significant feature of the A9K24X10GETR is its 24-port 10-Gigabit Ethernet module. This functionality allows for high-density connectivity, making it ideal for aggregating numerous connections to different parts of a network while maintaining optimal performance. Whether used for Internet service providers delivering high-speed connectivity or for enterprises looking to connect multiple branches, the A9K24X10GETR provides robust and reliable data transmission.

Further enhancing the capabilities of the ASR 9000 is the A9KMOD80TR module, which supports an extensive range of services. This module is designed to run a variety of technologies, including Layer 2 and Layer 3 services, MPLS (Multiprotocol Label Switching), and IPv6. Its ability to integrate seamlessly into existing infrastructures while providing the advanced features customers demand makes it an invaluable asset for network engineering teams.

Another cutting-edge technology present in the ASR 9000 Series is its support for eBGP (External Border Gateway Protocol), which plays a critical role in managing traffic across multiple networks. The routers are equipped with advanced telemetry features, empowering operators with real-time insights into network performance and health. Additionally, they come with integrated security features that protect against DDoS threats and other vulnerabilities.

In summary, Cisco's ASR 9000 Series, particularly the A9K24X10GETR and A9KMOD80TR, combines high-density connections, extensive service support, and advanced security and telemetry capabilities. These routers are perfect for demanding environments where reliable performance and adaptability are crucial. With their focus on innovation and performance, Cisco continues to shape the future of networking technology.
