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:

Cisco IOS XR Software documents listed in

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.

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.
