Managing Configuration History and Rollback

After each commit operation, the system saves a record of committed configuration changes. This record has only changes made during the configuration session; it does not contain the complete configuration. Each record is assigned a unique ID, a commitID. Using a commitID you can:

•Identify the previous configuration to which to return. Before rolling back the configuration to a specific commitID, consider the following:

–You cannot roll back to a configuration removed because of package incompatibility. Configuration rollbacks only succeed when the configuration passes all compatibility checks with the active Cisco IOS XR Software release.

–If the system finds an incompatible configuration during rollback, the operation fails and an error appears.

•Load configuration changes made during a configuration session

•Load configuration changes from multiple commitIDs

•Clear commitIDs

Cisco IOS XR automatically saves up to 100 of the most recent commitIDs.

The following sections describe how to manage configuration changes and roll back to a previously committed 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.
