Snapshots

This scenario shows how to generate and user configuration snapshots.

Test Snapshots

Description

Multiple snapshots are generated by committing changes in the configuration. Snapshots are a very powerful way for making quick configuration changes.

Scenario

Step 1: Run the command delete system snapshot all on DUT0 and expect no output.

Step 2: Set the following configuration in DUT0 :

set system description Initial
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system snapshots include-uncommented

Step 3: Modify the following configuration lines in DUT0 :

set system description Dummy1

Step 4: Run the command show snapshot on DUT0 and expect the following output:

Show output

      Snapshot        Comment
-----------------------------
20260519120950_commit <empty>

Step 5: Modify the following configuration lines in DUT0 :

set system description Dummy2

Step 6: Run the command show snapshot on DUT0 and expect the following output:

Show output

      Snapshot        Comment
-----------------------------
20260519120950_commit <empty>
20260519120952_commit <empty>

Step 7: Run the command show running on DUT0 and check whether the output matches the following regular expressions:

Dummy2

Show output

# Teldat OSDx VM version v4.2.10.0
# Tue 19 May 2026 12:09:52 +00:00
# Warning: Configuration has not been saved
set system description Dummy2
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system snapshots include-uncommented

Step 8: Run the command show changes snapshot 20260519120950_commit snapshot 20260519120952_commit on DUT0 and check whether the output matches the following regular expressions:

Dummy1

Show output

set system description Dummy1

Step 9: Modify the following configuration lines in DUT0 :

set system description Dummy1

Step 10: Run the command show running on DUT0 and check whether the output matches the following regular expressions:

Dummy1

Show output
