Sastre - Cisco-SDWAN Automation Toolset
Sastre provides functions to assist with managing configuration elements and visualize information from Cisco SD-WAN deployments.
Some use-cases include:
- Transfer configuration from one vManage to another. Lab or proof-of-concept environment to production, on-prem to cloud environments as examples.
- Backup, restore and delete configuration items. Tags and regular expressions can be used to select all or a subset of items.
- Visualize operational data across multiple devices. For instance, display status of control connections from multiple devices in a single table.
Sastre can also be used as an SDK to other applications, further information is available on DevNet Sastre SDK.
Sastre-Ansible is an Ansible Collection that exposes Sastre commands to Ansible Playbooks as a set of tasks and lookup plugins. Allowing users to build-up on Sastre functionality to create larger automation workflows.
Support enquires can be sent to sastre-support@cisco.com.
Note on vManage release support:
- Sastre 1.23 officially supports up to vManage 20.11. Newer vManage releases normally work without problems, just lacking support to the newer features added to that particular vManage release.
Sastre and Sastre-Pro
As of release 1.22, all functionality from Sastre-Pro is now available in Sastre. There is no functional difference between the two anymore.
Sastre continues as public open-source under MIT license available on Cisco DevNet repository. Supporting all tasks from Sastre-Pro.
Introduction
Sastre can be installed via pip, as a container or cloned from the git repository. Please refer to the Installing section for details.
The command line is structured as a set of base parameters, the task specification followed by task-specific parameters:
sdwan <base parameters> <task> <task-specific parameters>
Base parameters define global options such as verbosity level, vManage credentials, etc.
Task indicates the operation to be performed. The following tasks are currently available:
- Backup: Save vManage configuration items to a local backup.
- Restore: Restore configuration items from a local backup to vManage.
- Delete: Delete configuration items on vManage.
- Migrate: Migrate configuration items from a vManage release to another. Currently, only 18.4, 19.2 or 19.3 to 20.1 is supported. Minor revision numbers (e.g. 20.1.1) are not relevant for the template migration.
- Encrypt: Encrypt values using target vManage keys. Used to generate CRYPT_CLUSTER encrypted values, which can only be decrypted by the target vManage.
- Transform: Modify configuration items. Currently, copy, rename and crypt-update operations are supported.
- Attach: Attach WAN Edges/vSmarts to templates. Allows further customization on top of the functionality available via "restore --attach".
- Detach: Detach WAN Edges/vSmarts from templates. Allows further customization on top of the functionality available via "delete --detach".
- Certificate: Restore device certificate validity status from a backup or set to a desired value (i.e. valid, invalid or staging).
- List: List configuration items or device certificate information from vManage or a local backup.
- Show-template: Show details about device templates on vManage or from a local backup.
- Report: Generate a customizable report file containing the output of multiple commands. Also provide option to generate a diff between reports.
- Show: Run vManage real-time, state or statistics commands; collecting data from one or more devices. Query vManage alarms and events.
Task-specific parameters are provided after the task argument, customizing the task behavior. For instance, whether to execute a restore task in dry-run mode or the destination directory for a backup task.
Notes:
- Either 'sdwan' or 'sastre' can be used as the main command.
- The command line described above, and in all examples that follow, assume Sastre was installed via PIP.
- If Sastre was cloned from the git repository, then 'sdwan.py' or 'sastre.py' should be used instead. Please check the Installing section for more details.
Base parameters
% sdwan --help
usage: sdwan [-h] [-a <vmanage-ip>] [-u <user>] [-p <password>] [--tenant <tenant>] [--pid <pid>] [--port <port>] [--timeout <timeout>] [--verbose] [--debug] [--version] <task> ...
Sastre - Cisco-SDWAN Automation Toolset
positional arguments:
<task> task to be performed (backup, restore, delete, migrate, attach, detach, certificate, transform, list, show-template, show, report, encrypt)
<arguments> task parameters, if any
options:
-h, --help show this help message and exit
-a <vmanage-ip>, --address <vmanage-ip>
vManage IP address, can also be defined via VMANAGE_IP environment variable. If neither is provided user is prompted for the address.
-u <user>, --user <user>
username, can also be defined via VMANAGE_USER environment variable. If neither is provided user is prompted for username.
-p <password>, --password <password>
password, can also be defined via VMANAGE_PASSWORD environment variable. If neither is provided user is prompted for password.
--tenant <tenant> tenant name, when using provider accounts in multi-tenant deployments.
--pid <pid> CX project id, can also be defined via CX_PID environment variable. This is collected for AIDE reporting purposes. Use 0 if not applicable.
--port <port> vManage port number, can also be defined via VMANAGE_PORT environment variable (default: 443)
--timeout <timeout> REST API timeout (default: 300)
--verbose increase output verbosity
--debug include additional API call details to the log files
--version show program's version number and exit
vManage address (-a/--address), username (-u/--user), password (-p/--password) and port (--port) can also be provided via environment variables:
- VMANAGE_IP
- VMANAGE_USER
- VMANAGE_PASSWORD
- VMANAGE_PORT
A good approach to reduce the number of parameters that need to be provided at execution time is to create rc text files exporting those environment variables for a particular vManage. This is demonstrated in the Getting Started section below.
For any of these arguments, vManage address, user, password and CX pid; user is prompted for a value if they are not provided via the environment variables or command line arguments.
Task-specific parameters
Task-specific parameters and options are defined after the task is provided. Each task has its own set of parameters.
% sdwan backup -h
usage: sdwan backup [-h] [--archive <filename> | --workdir <directory>] [--no-rollover] [--save-running]
[--regex <regex> | --not-regex <regex>]
<tag> [<tag> ...]
Sastre - Cisco-SDWAN Automation Toolset
Backup task:
positional arguments:
<tag> one or more tags for selecting items to be backed up. Multiple tags should be separated by space. Available
tags: all, config_group, feature_profile, policy_customapp, policy_definition, policy_list,
policy_security, policy_vedge, policy_voice, policy_vsmart, template_device, template_feature. Special tag
"all" selects all items, including WAN edge certificates and device configurations.
options:
-h, --help show this help message and exit
--archive <filename> backup to zip archive
--workdir <directory>
backup to directory (default: backup_198.18.1.10_20220915)
--no-rollover by default, if workdir already exists (before a new backup is saved) the old workdir is renamed using a
rolling naming scheme. This option disables this automatic rollover.
--save-running include the running config from each node to the backup. This is useful for reference or documentation
purposes. It is not needed by the restore task.
--regex <regex> regular expression matching item names to backup, within selected tags.
--not-regex <regex> regular expression matching item names NOT to backup, within selected tags.
Important concepts:
- vManage URL: Constructed from the provided vManage IP address and TCP port (default 443). All operations target this vManage.
- Workdir: Defines the location (in the local machine) where vManage data files are located. By default, it follows the format "backup_<vmanage-ip>_<yyyymmdd>". The --workdir parameter can be used to specify a different location. Workdir is under a 'data' directory. This 'data' directory is relative to the directory where Sastre is run.
- Tag: vManage configuration items are grouped by tags, such as policy_apply, policy_definition, policy_list, template_device, etc. The special tag 'all' is used to refer to all configuration elements. Depending on the task, one or more tags can be specified in order to select groups of configuration elements.
Common behavior of "table" tasks:
A number of Sastre tasks provide output in the form of one or more tables. For instance, list, show-template and show tasks. There is a common set of options shared by all such tasks:
Table export options:
- --save-csv: Export as CSV file(s).
- --save-json: Export as JSON file(s).
Table filtering options:
- --include: Include rows matching the provided regular expression, exclude all other rows.
- --exclude: Exclude rows matching the provided regular expression.
Include/exclude regular expressions match on any cell value of the particular row. In other words, any cell value matching the regular expression will cause a row match.
Both --include and --exclude can be provided at simultaneously. In this case, exclude match is performed first then include.
Getting Started
Create a directory to serve as root for backup files, log files and rc files:
% mkdir sastre
% cd sastre
When Sastre is executed, data/ and logs/ directories are created as needed to store backup files and application logs. These are created under the directory where Sastre is run.
Create a rc-example.sh file to include vManage details and source that file:
% cat <<EOF > rc-example.sh
export VMANAGE_IP='198.18.1.10'
export VMANAGE_USER='admin'
EOF
% source rc-example.sh
Note that in this example the password was not defined, the user will be prompted for a password.
Test vManage credentials by running a simple query listing configured device templates:
% sdwan list configuration template_device
vManage password:

Overwriting items with the --update option:
- By default, when an item from the backup has the same name as an existing item on vManage it will be skipped by restore.
- For instance, if a device template is modified on vManage, restoring from a backup taken before the modification will skip that item.
- With the --update option, items with the same name are updated with the info found in the backup.
- Sastre only update items when there are differences between the backup and vManage content.
- If the item is associated with attached templates or activated policies, all necessary re-attach/re-activate actions are automatically performed.
- Currently, the --update option does not inspect changes to template values.

Migrating templates from pre-20.1 to post-20.1
- Template migration from pre-20.1 to post-20.1 format is supported. Maintenance numbers are not relevant to the migration. That is, 20.1 and 20.1.1 can be specified without any difference in terms of template migration.
- The source of templates can be a live vManage or a backup. The destination is always a local directory. A restore task is then used to push migrated items to the target vManage.
- Device attachments and template values are currently not handled by the migrate task. For instance, devices attached to a device template are left on that same template even when a new migrated template is created.
Migrating off a live vManage:

Basic customization of migrated template names:
- Using the --name option to specify the format for building migrated template names. Default is "migrated_{name}", where {name} is replaced with the original template name.
Example:
% sdwan --verbose migrate all dcloud_migrated --workdir dcloud_192 --name "201_{name}"
INFO: Starting migrate: Local workdir: "dcloud_192" 18.4 -> 20.1 Local output dir: "dcloud_migrated"

Regex-based customization of migrated template names:
- This example shows a more complex --name option, containing multiple {name} entries with regular expressions.
- Additional details about the name regex syntax are provided in the Template name manipulation via name-regex section.
Example:
% sdwan --verbose migrate all sastre_cx_golden_repo_201 --workdir sastre_cx_golden_repo --name '{name (G_.+)_184_.+}{name (G_VPN.+)}_201{name G.+_184(_.+)}'

Selectively attach/detach devices to/from templates
The attach and detach tasks expose a number of knobs to select templates and devices to be included:
- Templates regular expression, selecting templates to attach. Match on template name.
- Devices regular expression, selecting devices to attach. Match on device name.
- Reachability state
- Site-ID
- System-IP
When multiple filters are defined, the result is an AND of all filters. Dry-run can be used to validate the expected outcome.
The number of devices to include per attach/detach request (to vManage) can be defined with the --batch option.
Using dry-run mode to validate what templates and devices would be included with the attach task:
% sdwan --verbose attach edge --workdir dcloud_base --dryrun
INFO: Starting attach templates, DRY-RUN mode: Local workdir: "dcloud_base" -> vManage URL: "https://198.18.1.10"

% sdwan --verbose attach edge --workdir dcloud_base --templates 'DC' --devices 'VEDGE2'
INFO: Starting attach templates: Local workdir: "dcloud_base" -> vManage URL: "https://198.18.1.10"

Verifying device operational data
The show task provides commands to display operational data from devices, and vManage alarms and events.
Show devices, realtime, state and statistics share the same set of options to filter devices to display:
- --regex - Regular expression matching device name, type or model to display
- --not-regex - Regular expression matching device name, type or model NOT to display.
- --reachable - Display only reachable devices
- --site - Filter by site ID
- --system-ip - Filter by system IP
Verifying inventory of devices that are reachable and name starting with "pEdge3" or "pEdge4":
% sdwan show devices --reachable --regex 'pEdge[3-4]'
+==================================================================================+

recipe transform using custom recipe
build-recipe generate recipe file for updating vManage-encrypted fields
Transform can read from a live vManage or from a backup directory (when --workdir is specified). It always save the processed items to the provided output directory. Then restore/attach tasks can be used to push those changes to vManage.
Naming the new or renamed items can be done in a couple of ways:
- Name template: A name_regex expression defines how to build the new name based on the old name. This method is available via CLI or custom recipe.
- Name map: A 1-1 mapping from old name to new name is defined. This method is only available when using custom recipes.
- Name map + name template: When both name map and name template are defined, name map lookup is done first. Only if no match is found on name map, name template processing is done.
Renaming a feature-template using name template via transform rename:
- Rename Logging_Template_cEdge to Logging_Template_v01

Renaming multiple feature-templates using name template and name map via transform recipe:
- Using a custom recipe (defined in a YAML file or provided as a JSON string), allows more flexibility for defining which items are selected and how the new items should be named.

name_template:
regex: "^All-"
name_regex: "{name ^All-(.+)}"

Updating vManage-Encrypted values in configuration items
Transform task also supports updating vManage-encrypted values, allowing configuration items with values containing a CRYPT_CLUSTER prefix to be transferred to a different vManage.
The first step is to find out the vManage-encrypted values present on vManage or a backup. This is accomplished with the transform build-recipe task.
Generate a recipe skeleton for the transform task:

Entries with a '< CHANGE ME >' placeholder need to be replaced with new values encrypted by the target vManage where you need to restore this backup to. This is done using the encrypt task.
Using the encrypt recipe task, Sastre will update the recipe file by requesting a new clear text value for each '< CHANGE ME >' entry, requesting the target vManage to encrypt it and update the corresponding to_value field with the new encrypted value.
Update '< CHANGE ME >' entries in the recipe file:
% sdwan --verbose encrypt recipe recipe.yml
INFO: Encrypt task: vManage URL: "https://198.18.133.200:8443"
Interactive update of recipe file "recipe.yml", press <ENTER> on empty value or ^C to abort without saving.

Note that the 'recipe.yml' recipe file can also include name_template and/or name_map statements. This allows configuration items to be renamed or copied from, in addition to the crypt_updates.
Processing of crypt_updates happen after name_map and name_template. This means that resource_name entries under crypt_update match on the new names, post name_map and name_template processing.
As an example, this is a new version of 'recipe.yml' that also rename templates in the process:
tag: all
name_template:
regex: '^All-'
name_regex: '{name ^All-(.+)}'
name_map:

Note that crypt_update resource_name SNMP-Basic_cEdge_v6 is matching the new name post name_map update.
With the new recipe file prepared, the next step is to execute the transform recipe command.

Notes
Regular Expressions
It is recommended to always use single quotes when specifying a regular expression to --regex option:
sdwan --verbose restore all --regex 'VPN1'
This is to prevent the shell from interpreting special characters that could be part of the pattern provided.
Matching done by --regex is un-anchored. That is, unless anchor marks are provided (e.g. ^ or $), the specified pattern matches if present anywhere in the string. In other words, this is a search function.
The regular expression syntax supported is described in https://docs.python.org/3/library/re.html
Behavior of --regex and --not-regex:
- --regex is used to select items to include (i.e. perform task operation)
- --not-regex is used to define items not to include. That is, select all items, except the ones matching --not-regex.
- When --regex match on multiple fields (e.g. item name, item ID), an item is selected if the item name OR item ID match the regular expression provided.
- With --not-regex, when it matches on multiple fields (e.g. item name, item ID), all items are selected, except the ones where item name OR item ID match the regular expression.
Template name manipulation via name-regex
Multiple Sastre tasks utilize name-regex for name manipulation:
- Migrate task --name option accepts a name-regex.
- Transform copy/rename tasks have a
<name-regex>mandatory parameter. - Transform recipe task allow
name_regexundername_templatesection of the recipe YAML file. - The 'list transform' task also take a
<name-regex>parameter. This task was designed to facilitate testing of those expressions.
A name-regex is a template for creating a new name based on segments of an original name.
The following rules apply:
- Occurrences of {name} are replaced with the original item name.
- Sections of the original item name can be captured by providing a regular expression in the format: {name <regex>}. This regular expression must contain one or more capturing groups, which define segments of the original name to "copy". Segments matching each capturing group are concatenated and "pasted" to the {name} position.
- If the regular expression does not match, {name <regex>} is replaced with an empty string.
Example:
Consider the template name "G_Branch_184_Single_cE4451-X_2xWAN_DHCP_L2_v01".
In order to get the migrated name as "G_Branch_201_Single_cE4451-X_2xWAN_DHCP_L2_v01", one can use --name '{name (G_.+)_184_.+}_201_{name G.+_184_(.+)}'.
% sdwan list transform template_device --regex 'G_Branch_184_Single_cE4451' --workdir sastre_cx_golden_repo '{name (G_.+)184.+}201{name G.+184(.+)}'
+===================================================================================================================================================================+
| Name | Transformed | Tag | Type |
+===================================================================================================================================================================+
| G_Branch_184_Single_cE4451-X_2xWAN_Static_2xSLAN_Trunk_L2_v01 | G_Branch_201_Single_cE4451-X_2xWAN_Static_2xSLAN_Trunk_L2_v01 | template_device | device template |
| G_Branch_184_Single_cE4451-X_2xWAN_DHCP_L2_v01 | G_Branch_201_Single_cE4451-X_2xWAN_DHCP_L2_v01 | template_device | device template |
+---------------------------------------------------------------+---------------------------------------------------------------+-----------------+-----------------+
Logs
Sastre logs messages to the terminal and to log files (under the logs/ directory).
Debug-level and higher severity messages are always saved to the log files.
The --verbose flag controls the severity of messages printed to the terminal. If --verbose is not specified, only warning-level and higher messages are logged. When --verbose is specified, informational-level and higher messages are printed.
Restore behavior
By default, restore will skip items with the same name. If an existing item on vManage has the same name as an item in the backup this item is skipped from restore.
Any references/dependencies on that item are properly updated. For instance, if a feature template is not pushed to vManage because an item with the same name is already present, device templates being pushed will now point to the feature template which is already on vManage.
Restore with --update:
Adding the --update option to restore modifies this behavior. In this case, Sastre will update existing items containing the same name as in the backup, but only if their content is different.
When an existing vManage item is modified, device templates may need to be reattached or vSmart policies may need to be re-activated. This is handled as follows:
- Updating items associated with an active vSmart policy may require this policy to be re-activated. In this case, Sastre will request the policy reactivate automatically.
- On updates to master templates (e.g. device template) containing attached devices, Sastre will re-attach the device templates.
- On Updates to child templates (e.g. feature template) associated with master templates containing attached devices, Sastre will re-attach the affected master template(s).
- In all re-attach cases, Sastre will use the existing attachment values on vManage to feed the attach request.
The implication is that if modified templates define new variables re-attach will fail, because not all variables would have values assigned. In this case, the recommended procedure is to detach the master template (e.g. using detach task), re-run "restore --update", then re-attach the device-template from vManage, where one would be able to supply any missing variable values.
Factory default items:
If a factory-default item in the backup is a dependency (referenced by other items) that is missing on the target vManage, it is converted to a non-default item and pushed to vManage.
A WARNING message is displayed when this condition happens. The user may want to review the corresponding templates/policies and update them to reference newer versions or equivalent factory-defaults that may be available on vManage.
Installing
Sastre requires Python 3.8 or newer. This can be verified by pasting the following to a terminal window:
% python3 -c "import sys;assert sys.version_info>(3,8)" && echo "ALL GOOD"
If 'ALL GOOD' is printed it means Python requirements are met. If not, download and install the latest 3.x version at Python.org (https://www.python.org/downloads/).
The recommended way to install Sastre is via pip. For development purposes, Sastre can be installed from the GitHub repository. Both methods are described in this section.
PIP install in a virtual environment (recommended)
Create a directory to store the virtual environment and runtime files:
% mkdir sastre
% cd sastre
Create virtual environment:
% python3 -m venv venv
Activate virtual environment:
% source venv/bin/activate
(venv) %
- Note that the prompt is updated with the virtual environment name (venv), indicating that the virtual environment is active.
Upgrade initial virtual environment packages:
(venv) % pip install --upgrade pip setuptools
Install Sastre:
(venv) % pip install --upgrade cisco-sdwan
Verify that Sastre can run:
(venv) % sdwan --version
Notes:
- The virtual environment is deactivated by typing 'deactivate' at the command prompt.
- Before running Sastre, make sure to activate the virtual environment back again (source venv/bin/activate).
PIP install
With this option you will likely need to run the pip commands as sudo.
Install Sastre:
% python3 -m pip install --upgrade cisco-sdwan
Verify that Sastre can run:
% sdwan --version
GitHub install
Clone from the GitHub repository:
% git clone https://github.com/CiscoDevNet/sastre
Move to the clone directory:
% cd sastre
Create virtual environment:
% python3 -m venv venv
Activate virtual environment:
% source venv/bin/activate
(venv) %
- Note that the prompt is updated with the virtual environment name (venv), indicating that the virtual environment is active.
Upgrade initial virtual environment packages:
(venv) % pip install --upgrade pip setuptools
Install required Python packages:
(venv) % pip install -r requirements.txt
Verify that Sastre can run:
(venv) % python3 sdwan.py --version
Docker install
First, proceed with the GitHub install outlined above.
Ensure you are within the directory cloned from GitHub:
% cd sastre
Then proceed as follows to build the docker container:
% docker build -t sastre .

Notes:
- When set, host proxy environment variables (http_proxy, https_proxy and no_proxy) are used during the build and execution of the container.
- The container has a /shared-data volume.
- Sastre data/ and logs/ directories are created under /shared-data.
- A sample dcloud-lab.sh is copied to /shared-data/rc if no /shared-data/rc directory is present.
- Directory structure:
- /shared-data/data - Used as the vManage backup data repository
- /shared-data/logs - Where the logs are saved
- /shared-data/rc - Used to store 'rc' files defining environment variables used by Sastre: VMANAGE_IP, VMANAGE_USER, etc.
- The suggested docker run command above bind-mounts the /shared-data volume, i.e. it is mapped to a host system directory. This facilitates transferring of data to/from the container (e.g. vManage backups). The host directory is relative to the location where the docker run command is executed.
- Docker run will spin-up the container and open an interactive session to it using the ash shell. Sdwan commands (e.g. sdwan backup all, etc.) can be executed at this point. Typing 'exit' will leave the ash shell, stop and remove the container. Everything under data, rc and logs is persisted to the corresponding host system directories.
