AXP CLI API

---

The Cisco AXP CLI API is explained in the following sections:

•Overview

•Java

•C/C++

•Perl

•Python

•Bash

Overview

Use the AXP CLI API to issue commands on the Cisco AXP service module. Supported languages are: Java, C/C++, Python, Perl, and Bash.

Multiple configuration commands can be passed at one time by using a comma delimiter. This applies to both exec and configuration commands.

For example, multiple commands can be invoked as follows.

iosapi --mode exec "show clock, show clock"

---

Note Commands that require interaction from the user cannot be executed programmatically using the
AXP CLI API.

Class and Methods

Table 20 Java AXP CLI API Class and Methods

Class/Method
public class AppreMessage { public void setRequest(String request); public String getResponse(); public String getRequest() public void setRequest(String request) public String getResponse() public void setResponse(String response) }

Table 21 shows returned integer values; for example, from calls to exec( ).

Error Status Code and Error String

Table 21 AXP CLI API Return Status Codes

Error Status Code	Value	Description
AppreAPI.OK	0	Request successfully processed.
AppreAPI.FAIL	1	Request aborted because of an error. If a response string is returned (Java/C), it contains a description of the error.
AppreAPI.FILE	2	Request processed. If a response string is returned (Java/C), it contains the filename and path, and is written to a file.

The error string contains the following: "Application [name] Start Failed: [reason]"

Java Example

import com.cisco.aesop.apphosting.appreapi.*;

public static void main (String[] args){

	int status = 0;

	CommonServiceImpl apiCall = new CommonServiceImpl();

	AppreMessage msg = new AppreMessage();

	msg.setRequest("show run");

status = apiCall.exec(msg)

status = apiCall.config(msg)

•IosServiceAPI_t

Class and Methods

AppreMessage_t is a struct containing the request and response string.

typedef struct AppreMessage_t{

char* request;

char* response;

int size;

} AppreMessage_t;

---

Note The caller is responsible for allocating and freeing memory space occupied by the response string.

---

IosServiceAPI_t

typedef struct IosServiceAPI_t {

	apiMethod    exec;

	apiMethod    config;

} IosServiceAPI_t;

extern int getIosApi(const char *serviceName, IosServiceAPI_t* iosapi);

void set_timeout (int sec)

Table 22 shows returned integer values ; for example, from calls to exec( ).

Error Status Code and Error String

Table 22 Java AXP CLI Return Status Codes

Status Code	Value	Description
APPRE_OK	0	Request successfully processed.
APPRE_FAIL	1	Request aborted because of an error. If a response string is returned (Java/C), it contains a description of the error.
APPRE_FILE	2	Request processed. If a response string is returned (Java/C), it contains the filename and path, and is written to a file.

The error string contains the following data: "Application [name] Start Failed: [reason]"

C/C++ Example

---

Note The calling program is responsible for freeing allocated memory. If the calling program sets the char* to NULL, the system allocates the required memory, but the calling program is responsible for freeing the memory.

---

#include "appreapi.h"

int main(int argc, char** argv){

	char buf[] = "show run";

	AppreMessage_t msg;

	msg.size = 0;

	msg.response = NULL; 

	msg.request = buf; 

	int status = APPRE_FAIL;

	status = appreapi_conf(&msg);

	status = appreapi_exec(&msg);

	return status;

sub exec (request)

sub config (request)

Perl Example

use AppreAPI;

$api = new AppreAPI::AppreAPI();

$req = "show run";

($val, $res) = $api->exec($req);

($val, $res) = $api->config($req);

Class and Methods

sub exec (self, request)

sub config (self, request)

Python Example

The request string is input and the status code value is output.

from AppreAPI import *

api=AppreAPI()

request = "show run"

status, response = api.exec(request)

status, response = api.config(request)

Bash

•Bash Signatures

•Bash Examples

Bash Signatures

For Bash, commands can be passed as a command list or in a file.

appreapi [--mode name] cmdlist [--timeout <second>]

appreapi [--mode name] --file filename [--timeout <second>]

mode: specifies whether command is an exec or config mode command

cmdlist:

•config mode: string containing one command

•exec mode: string containing multiple commands separated by commas

---

Note Commas are used to separate commands in the AXP CLI API. (See the Bash example config command below.) However, for the IOS CLI API, semi-colons are used to separate commands.

---

filename: full path of the file containing list of commands

timeout: connection timeout [in seconds]—not the response timeout

Bash Examples

exec command

bash-3.2# appreapi --mode exec "show clock"

03:09:15.186 GMT Fri Oct 30 2009

bash-3.2# 

exec command (unsuccessful as the command has invalid syntax)

bash-3.2# appreapi --mode exec "show abc"

Could not understand: abcbash-3.2#

config command

bash-3.2# appreapi --mode config "netconf max-sessions 5, no netconf max-sessions"

bash-3.2#

config command (unsuccessful as the config command can only have a value for username of "sysadmin", not "abc")

bash-3.2# appreapi --mode config "username abc password 0 abc"

Could not understand: abcbash-3.2#
