AXP SysInfo API

•Overview

•Java

•Python

•Perl

Overview

Use the AXP SysInfo API to run selected commands on the router, using an application running in the AXP Reference OS or AXPUDL. For selected commands, see the "Description" section.

Interfaces for Java, C/C++, Perl, and Python are listed below and are similar for both of the System APIs: AXP SysInfo API, and AXP SysOp API. (Both of these APIs share the APIs for Param, ParamList, ParamListList, and ErrorInfo.)

Data Model

The following data is used by the AXP SysInfo API:

•SysInfoRequest

•SysInfoResponse

SysInfoRequest

The following diagram shows some of the XML data elements that are used by the SysInfo API. Also, refer to the "Appendix I: API Schemas" section on page 340.

Figure 10 SysInfoRequest Data

For further information on the data schemas, refer to the "Appendix I: API Schemas" section on page 340.

Table 59 SysInfoRequest Data

Element
Description

serviceInfo

This element is included in all requests and provides the information common to any type of service

serviceType

Determines if service request is for IOS or AXP. For SysInfoRequest, AXP is the only valid value

serviceRequestor

Name of the virtual interface, set by the system

serviceAddress

IP/hostname of the Cisco IOS router, which is used for IOS serviceType. For AXP 1.5 or higher, the serviceAddress cannot be set

genericSysInfoReq

Details of the response

reqName

Requested service. For example, "swapStatistics", "routerInfo"

subName

Optional further information for service

paramList

Name value pairs (param) holding data for the requested command

param

Name-value pair information—query data for obtaining system information


SysInfoResponse

The following diagram shows a selection of XML data elements that are used by the SysInfo API.
For further information on the data schemas, refer to the "Appendix I: API Schemas" section on page 340.

Figure 11 SysInfoResponse Data

Table 60 SysInfoResponse Elements

Element
Description

errorInfo

errorCode and errorMessage—data is only present when a request is unsuccessful

errorCode

Code representing the cause of failure of the request

errorMessage

Describes the cause of failure of the request

genericSysInfoResp

Details of the response

paramList

List of params (name-value pairs) in the response

param

Name-value pair within the paramList


Description

Use the AXP SysInfo API to obtain the following AXP system information:

•Request for routerInfo

•Request for swapStatistics

The method of obtaining system information is to first send request information using a SysInfoRequest object. (For example, a request to show the swap statistics.) Then a response is returned in a SysInfoResponse object, which contains values in the paramList.

The following two requests can be made using SysInfoRequest objects: routerInfo (obtain IP address of the router), and swapStatistics (equivalent to the swap statistics CLI command).

Request for routerInfo

Submit a request with reqName = "routerInfo".

The response contains a paramList—one param containing a name-value of "ipAddress" and the
<ip address of the router>.

Request for swapStatistics

Submit a request with reqName = "swapStatistics". The response contains a paramList—three params with name-value amounts of swap space shown in Table 61.

Table 61 paramList values

Name
Value

swapTotal

Total swap space allocated, in KB

swapUsed

Currently used swap space, in KB

swapFree

Available swap space, in KB


Example

The following example, in pseudocode, describes a process that uses the AXP SysInfo API to request "swap statistics". 


	get SysInfoRequest

	set request name to 'swapStatistics'

	execute request

	if the response is successful

		get the parameter list of lists

		get the list

		if the list exists

			get the value of the 'swapFree' parameter

			print the value
