Command-Line Interface

The CLI is a user interface for monitoring and maintaining the router and also for configuring basic router features. Through the CLI you execute the Cisco IOS XR commands.

All procedures in this guide use CLI. Before you can use other router management interfaces, first use the CLI to install and configure those interfaces. Guidelines for using CLI to configure the router are discussed in the following chapters:

•Chapter 3, “Configuring General Router Features”

•Chapter 4, “Configuring Additional Router Features”

•Chapter 5, “CLI Tips, Techniques, and Shortcuts”

For more CLI procedures, like hardware interface and software protocol management tasks, see the Cisco IOS XR Software documents listed in “Related Documents” section on page viii.

Extensible Markup Language API

The Extensible Markup Language (XML) application programming interface (API) is an XML interface used for rapid development of client applications and perl scripts to manage and monitor the router. Client applications can configure the router or request status information from the router by encoding a request in XML API tags and sending it to the router. The router processes the request and sends the response to the client in the form of encoded XML API tags. The XML API supports readily available transport layers, including Telnet, Secure Shell (SSH) and Secure Socket Layer (SSL) transport.

For more information, see the Cisco IOS XR Software documents listed in the “Related Documents” section on page viii.

Simple Network Management Protocol

Simple Network Management Protocol (SNMP) is an application-layer protocol that facilitates management information exchange between network devices. By using SNMP-transported data (such as packets per second and network error rates), network administrators can manage network performance, find and solve network problems, and plan for network growth.

The Cisco IOS XR Software supports SNMP v1, v2c, and v3. SNMP is part of a larger architecture called the Internet Network Management Framework (NMF), which is defined in Internet documents called RFCs. The SNMPv1 NMF is defined by RFCs 1155, 1157, and 1212, and the SNMPv2 NMF is defined by RFCs 1441 through 1452. For more information on SNMP v3, see RFC 2272 and 2273.

SNMP is a popular protocol for managing diverse commercial internetworks and those used in universities and research organizations. SNMP-related standardization activity continues even as vendors develop and release state-of-the-art, SNMP-based management applications. SNMP is a relatively simple protocol, yet its feature set is sufficiently powerful to handle the difficult problems presented in trying to manage the heterogeneous networks of today.

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.
