System Management and Configuration

Cisco IOS XR Software

The Cisco ASR 9000 Series Router run Cisco IOS XR Software and use the manageability architecture
of that operating system, which includes CLI, SNMP, and XML. Craft Works Interface (CWI), a
graphical craft tool for performance monitoring, is embedded with the Cisco IOS XR Software and can
be downloaded through the HTTP protocol. However, the Cisco ASR 9000 Series only supports a subset
of CWI functionality. In this mode, a user can edit the router configuration file, open Telnet/SSH
application windows, and create user-defined applications.

System Management Interfaces

The system management interfaces consist of the CLI, XML, and SNMP protocols. By default, only CLI
on the console is enabled. When the management LAN port is configured, various services can be started
and used by external clients, such as Telnet, SSH, and SNMP, In addition, TFTP and Syslog clients can
interact with external servers. CWI can be downloaded and installed on a PC or Solaris box.
For information about SNMP, see the
All system management interfaces have fault and physical inventory.

Command Line Interface

The CLI supports configuration file upload and download through TFTP. The system supports generation
of configuration output without any sensitive information such as passwords, keys, etc. The
Cisco ASR 9000 Series supports Embedded Fault Manager (TCL scripted policies) through CLI
commands. The system also supports feature consistency between the CLI and SNMP management
interfaces.

Craft Works Interface

The system supports CWI, a graphical craft tool for performance monitoring, configuration editing, and
configuration rollback. CWI is embedded with IOS XR and can be downloaded through the HTTP
protocol. A user can use CWI to edit the router configuration file, create user-defined applications, and
open Telnet/SSH application windows to provide CLI access.

XML

External (or XML) clients can programmatically access the configuration and operational data of the
Cisco ASR 9000 Series Router using XML. The XML support includes retrieval of inventory, interfaces,
alarms, and performance data. The system is capable of supporting 15 simultaneous XML/SSH sessions.
The system supports alarms and event notifications over XML and also supports bulk PM retrieval and
bulk alarms retrieval.
XML clients are provided with the hierarchy and possible contents of the objects that they can include
in their XML requests (and can expect in the XML responses), documented in the form of an XML
schema.
When the XML agent receives a request, it uses the XML Service Library to parse and process the
request. The Library forwards the request to the Management Data API (MDA) Client Library, which
retrieves data from the SysDB. The data returned to the XML Service Library is encoded as XML
