Exec Scripts

Cisco IOS XR exec scripts are on-box scripts that automate configurations of devices in the network. The exec scripts are written in Python using the Python libraries that Cisco provides with the base package. For the list of supported packages

A script management repository on the router manages the exec scripts. This repository is replicated on both RPs.

In IOS XR, AAA authorization controls the user access and privileges to perform operations. To run the exec script, you must have root user permissions.

Exec scripts provide the following advantages:

Provides automation capabilities to simplify complex operations.
Create customized operations based on the requirement.
Provide flexibility in changing the input parameters for every script run. This fosters dynamic automation of operational information.
Detect and display errors and warnings when executing an operation.
Run multiple automated operations in parallel without blocking the console.

This chapter gets you started with provisioning your Python automation scripts on the router.

Note

This chapter does not delve into creating Python scripts, but assumes that you have basic understanding of Python programming language. This section will walk you through the process involved in deploying and using the scripts on the router.

Workflow to Run an Exec Script

Complete the following tasks to provision exec scripts:

Download the script—Add the script to the appropriate exec script directory on the router. using the script add exec command.
Configure checksum—Check script integrity and authenticity using the script exec <script.py> checksum command.
Run the script—Trigger changes to the router configuration. Include arguments, set the maximum time for the script to run, setup log levels using the script run command.
View the script execution details—Validate the script and retrieve the operational data using the show script execution command.

Download the Script to the Router

To manage the scripts, you must add the scripts to the script management repository on the router. A subdirectory is created for each script type. By default, this repository stores the downloaded scripts in the appropriate subdirectory based on script type.


Script Type	Download Location
config	harddisk:/mirror/script-mgmt/config
exec	harddisk:/mirror/script-mgmt/exec
process	harddisk:/mirror/script-mgmt/process
eem	harddisk:/mirror/script-mgmt/eem

The scripts are added to the script management repository using two methods:

Method 1: Add script from a server
Method 2: Copy script from external repository to harddisk using scp or copy command

In this section, you learn how to add exec-script.py script to the script management repository.

Procedure

Step 1

Add the script to the script management repository on the router using one of the two options:

Add Script From a Server

Add the script from a configured HTTP server or the harddisk location in the router.

Router#script add exec <script-location> <script.py>

The following example shows a config script exec-script.py downloaded from an external repository http://192.0.2.0/scripts:

Router#script add config http://192.0.2.0/scripts exec-script.py
Fri Aug 20 05:03:40.791 UTC
exec-script.py has been added to the script repository

You can add a maximum of 10 scripts simultaneously.

Router#script add exec <script-location> <script1.py> <script2.py> ... <script10.py>

You can also specify the checksum value while downloading the script. This value ensures that the file being copied is genuine. You can fetch the checksum of the script from the server from where you are downloading the script. However, specifying checksum while downloading the script is optional.

Note

Only SHA256 checksum is supported.

Router#script add exec http://192.0.2.0/scripts exec-script.py checksum SHA256 <checksum-value>

For multiple scripts, use the following syntax to specify the checksum:

Router#script add exec http://192.0.2.0/scripts <script1.py> <script1-checksum> <script2.py> <script2-checksum>
... <script10.py> <script10-checksum>

If you specify the checksum for one script, you must specify the checksum for all the scripts that you download.

Copy the Script from an External Repository
You can copy the script from the external repository to the routers' harddisk and then add the script to the script management repository.
1. Copy the script from a remote location to harddisk using scp or copy command.
```
Router#scp userx@192.0.2.0:/scripts/exec-script.py /harddisk:/
```
2. Add the script from the harddisk to the script management repository.
```
Router#script add exec /harddisk:/ exec-script.py
Fri Aug 20 05:03:40.791 UTC
exec-script.py has been added to the script repository
```

Step 2

Verify that the scripts are downloaded to the script management repository on the router.

Example:

Router#show script status
Wed Aug 25 23:10:50.453 UTC
==========================================================================================
 Name              | Type     | Status           | Last Action | Action Time
------------------------------------------------------------------------------------------
 exec-script.py    | exec     | Config Checksum  | NEW         | Tue Aug 24 10:18:23 2021
 ==========================================================================================

Script exec-script.py is copied to harddisk:/mirror/script-mgmt/exec directory on the router.

Configure Checksum for Exec Script

Every script is associated with a checksum value. The checksum ensures the integrity of the script that is downloaded from the server or external repository is intact, and that the script is not tampered. The checksum is a string of numbers and letters that act as a fingerprint for script. The checksum of the script is compared with the configured checksum. If the values do not match, the script is not run and a syslog warning message is displayed.

It is mandatory to configure the checksum to run the script.

Note

Exec scripts support SHA256 checksum.

Before you begin

Ensure that the script is added to the script management repository. See Download the Script to the Router.

Procedure

Step 1	Retrieve the SHA256 checksum hash value for the script. Ideally this action would be performed on a trusted device, such as the system on which the script was created. This minimizes the possibility that the script is tampered with. Example: `Server$sha256sum sample1.py 94336f3997521d6e1aec0ee6faab0233562d53d4de7b0092e80b53caed58414b sample1.py` Make note of the checksum value.
Step 2	View the status of the script. Example: Router#show script status detail Fri Aug 20 05:04:13.539 UTC ====================================================================================================== Name \| Type \| Status \| Last Action \| Action Time ------------------------------------------------------------------------------------------------------ sample1.py \| exec \| Config Checksum \| NEW \| Fri Aug 20 05:03:41 2021 ------------------------------------------------------------------------------------------------------ Script Name : sample1.py History: -------- 1. Action : NEW Time : Fri Aug 20 05:03:41 2021 Description : User action IN_CLOSE_WRITE =========================================================================================== The `Status` shows that the checksum is not configured.
Step 3	Enter global configuration mode. Example: `Router#configure`
Step 4	Configure the checksum. Example: `Router(config)#script exec sample1.py checksum SHA256 94336f3997521d6e1aec0ee6faab0233562d53d4de7b0092e80b53caed58414b Router(config)#commit Tue Aug 24 10:23:10.546 UTC Router(config)#end`
Step 5	Verify the status of the script. Example: Router#show script status detail Fri Aug 20 05:06:17.296 UTC ====================================================================================================== Name \| Type \| Status \| Last Action \| Action Time ------------------------------------------------------------------------------------------------------ sample1.py \| exec \| Ready \| NEW \| Fri Aug 20 05:03:41 2021 ------------------------------------------------------------------------------------------------------ Script Name : cpu_load.py Checksum : 94336f3997521d6e1aec0ee6faab0233562d53d4de7b0092e80b53caed58414b History: -------- 1. Action : NEW Time : Fri Aug 20 05:03:41 2021 Checksum : 94336f3997521d6e1aec0ee6faab0233562d53d4de7b0092e80b53caed58414b Description : User action IN_CLOSE_WRITE =========================================================================================== The status `Ready` indicates that the checksum is configured and the script is ready to be run. When the script is run, the checksum value is recalculated to check if it matches with the configured hash value. If the values differ, the script fails. It is mandatory for the checksum values to match for the script to run.

Run the Exec Script

To run an exec script, use the script run command. After the script is run, a request ID is generated. Each script run is associated with a unique request ID.

Before you begin

Ensure the following prerequisites are met before you run the script:

Download the Script to the Router
Configure Checksum for Exec Script

Procedure

Run the exec script.

Example:


Router#script run sample1.py
Wed Aug 25 16:40:59.134 UTC
Script run scheduled: sample1.py. Request ID: 1629800603
Script sample1.py (exec) Execution complete: (Req. ID 1629800603) : Return Value: 0 (Executed)

Scripts can be run with more options. The following table lists the various options that you can provide at run time:


Keyword	Description
arguments	Script command-line arguments. Syntax: Strings in single quotes. Escape double quotes inside string arguments (if any). For example: `Router#script run sample1.py arguments 'hello world' '-r' '-t' 'exec' '--sleep' '5' description "Sample exec script"`
background	Run script in background. By default, the script runs in the foreground. When a script is run in the background, the console is accessible only after the script run is complete.
description	Description about the script run. `Router#script run sample1.py arguments '-arg1' 'reload' '-arg2' 'all' 'description' "Script reloads the router"` When you provide both the argument and description ensure that the arguments are in single quote and description is in double quotes.
log-level	Script logging level. The default value is `INFO`. You can specifiy what information is to be logged. The log level can be set to one of these options—Critical, Debug, Error, Info, or Warning.
log-path	Location to store the script logs. The default log file location is in the script management repository harddisk:/mirror/script-mgmt/logs.
max-runtime	Maximum run-time of script can be set between 1–3600 seconds. The default value is 300.

The script run is complete.

Manage Scripts

This section shows the additional operations that you can perform on a script.

Delete Exec Script from the Router

Delete the script from the script management repository using the script remove command. This repository stores the downloaded scripts.

Procedure

Step 1

View the list of scripts present in the script management repository.

Example:

Router#show script status
Wed Aug 25 23:10:50.453 UTC
======================================================================================================
Name       | Type   | Status          | Last Action | Action Time
------------------------------------------------------------------------------------------------------
sample1.py | exec   | Config Checksum | NEW         | Tue Aug 24 10:18:23 2021
sample2.py | exec   | Config Checksum | NEW         | Wed Aug 25 23:44:53 2021
sample3.py | config | Config Checksum | NEW         | Wed Aug 25 23:44:57 2021

Ensure the script you want to delete is present in the repository.

Step 2

Delete the script.

Example:

Router#script remove exec sample2.py
Wed Aug 25 231:46:38.170 UTC
sample2.py has been deleted from the script repository

You can also delete multiple scripts simulataneoulsy.

Step 3

Verify the script is deleted from the subdirectory.

Example:

Router#show script status
Wed Aug 25 23:48:50.453 UTC
======================================================================================================
Name       | Type   | Status          | Last Action | Action Time
------------------------------------------------------------------------------------------------------
sample1.py | exec   | Config Checksum | NEW         | Tue Aug 24 10:18:23 2021
sample3.py | config | Config Checksum | NEW         | Wed Aug 25 10:44:57 2021

The script is deleted from the script management repository.

Example: Exec Script to Verify Bundle Interfaces

In this example, you create a script to verify the bandwidth usage of bundle interfaces on the router, and check if it is beyond the defined limit. If usage is above the limit, the script generates a syslog indicating that the bandwidth is above the limit, and additional interfaces must be added to the bundle.

Before you begin

Ensure you have completed the following prerequisites before you validate the script:

Create an exec script verify_bundle.py. Store the script on an HTTP server or copy the script to the harddisk of the router.

"""
Bundle interfaces bandwidth verification script

Verify bundle interfaces mpls packets per sec is below threshold.
If pkts/sec is greater than threshold then print syslog message
and add list of new interfaces to bundle
