Committing a Configuration from Global Configuration Mode: Example

In the following example, the default commit command is entered in global configuration mode:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# interface Gi 0/0/0/2

RP/0/RSP0/CPU0:router(config-if)# description faq

RP/0/RSP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0

RP/0/RSP0/CPU0:router(config-if)# commit

RP/0/0/0:Aug 6 09:26:17.781 : %LIBTARCFG-6-COMMIT Configuration committed by user ‘cisco'. Use 'show configuration commit changes 1000000124' to view the changes.

Note The preceding message is stored in the log and displays only if logging is configured to display on screen.

Committing a Configuration from Administration Configuration Mode: Example

In the next example, the commit command is entered with the label and comment options in administration configuration mode:

RP/0/RSP0/CPU0:router# admin RP/0/RSP0/CPU0:router(admin)# configure RP/0/RSP0/CPU0:router(admin-config)# sdr test RP/0/RSP0/CPU0:router(admin-config-sdr:test)# location 0/1/* primary RP/0/RSP0/CPU0:router(admin-config-sdr:test)# commit label test comment This is a test RP/0/RSP0/CPU0:router(admin-config)# show configuration commit list detail

Note Configuration files are stored on the same flash disk as the boot image. Access these configurations only through the CLI commands for configuration management, history, and rollback. Direct modification or deletion of these files can result in lost router configurations.

Reloading a Failed Configuration

If the router displays a configuration failure message when you attempt to commit a configuration change, the configuration changes are not lost. While you remain in global configuration mode or administration configuration mode, you can load the configuration changes into the target configuration, correct the errors, and commit the changes. To load a failed configuration, go to global configuration or administration configuration mode and type the load configuration failed commit command, as shown in the following example:

RP/0/0/CPU0:router(config)# load configuration failed commit

RP/0/0/CPU0:router(config)# show configuration

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.
