Chapter 4 Configuring Virtual Contexts
Using the Configuration Checkpoint and Rollback Service
Procedure
Step 1 Choose Config > Virtual Contexts > admin context > System > Checkpoints.
The Checkpoints table appears.
For descriptions of the checkpoints, see Table 4-12.
Step 2 In the Checkpoints table, click Create Checkpoint.
The Create Checkpoint dialog box appears.
Step 3 In the Checkpoint Name field of the Create Checkpoint dialog box, specify a unique identifier for the
checkpoint.
Enter a text string with no spaces and a maximum of 25 alphanumeric characters.
If the checkpoint already exists, you are prompted to use a different name.
Step 4 Do one of the following:
• Click OK to save your configuration checkpoint. You return to the Checkpoints table and the new
checkpoint appears in the table.
• Click Cancel to exit the procedure without saving the configuration checkpoint and to return to the
Checkpoints table.
Deleting a Configuration Checkpoint
You can delete a checkpoint. Deleting a checkpoint from an ACE context directly will not trigger an
autosynchronization to occur on the ACE Appliance Device Manager for that context.
Prerequisite
Before you perform this procedure, make sure that you want to delete the checkpoint. Once you click
the Trash icon, the ACE removes the checkpoint from Flash memory.
This functionality on the DM requires that SSH is enabled on the appliance. Also, ensure that the ssh
key rsa 1024 force command is applied on the appliance.
Procedure
Step 1 To choose a virtual context that you want to create a configuration checkpoint, choose Config > Virtual
Contexts > admin context > System > Checkpoints.
The Checkpoints table appears.
