Configure Wi-Fi

CV-CUE provides a convenient way to configure your Wi-Fi network via the Configure tab.

All configuration in CV-CUE is done at the location level. So, when you create an SSID or enable Smart Steering, you do this for a location. This is because most configuration parameters are relevant to a location rather than a particular device. For example, all devices in an office are likely to broadcast the same SSID's.
Note: By default, configurations at a location are automatically inherited by its child locations. For example, suppose there is an HQ location with two child locations: Branch 1 and Branch 2. Then a configuration applied to HQ automatically applies to Branch 1 and Branch 2. You can, however, customize the configuration of a child location so that it is different from that of its parent.
The Configure tab allows you to configure the following:

Service Impact of Configuration Changes

CV-CUE warns a user of any service impact caused by settings changed on the UI. In general, the configuration changes affect the Wi-Fi service as follows:
  • Changes to SSID settings cause the SSID to restart.
  • Changes to RADIUS profiles, Role Profiles, and Tunnel Interfaces cause SSIDs using these profiles to restart.
  • Changes to Device and Radio Settings can cause either SSIDs using these settings to restart or Access Points (APs) using these settings to reboot.
Exceptions to the general rule exist—settings that do not cause any service interruptions. The table below is a tab-wise list of the impact that each setting change has on the Wi-Fi service.

- Inter AP Sync Period

 SSIDs using these settings restart.
- SSID VLAN Monitoring

- IPv4/IPv6 Dual Stack

- Turn Access Points into Dedicated WIPS Sensors

- Link Aggregation

- Transmit Hash Policy

 APs using these settings reboot.
Mesh Profile Mesh Profile Enabled

Mesh Profile Disabled

 Mesh APs reboot.

Note: When you edit an “enabled” mesh profile, mesh links are re-established, which may disrupt Wi-Fi service to clients.
Monitor > WiFi > Access Points > Customize VLANs Any setting AP reboots.
Monitor > WiFi > Access Points > Customize Transmit Power or Channel Any setting SSIDs on the AP restart.
Monitor > WiFi > Access Points > Assign/Reassign to Group OR Remove Access Points from Group
Other screens from which you can change AP-group assignment:
  • System > Navigator> Show Available Devices
  • Floor Plan
 The service impact depends on which settings at the current location change because of the operation. APs or the SSIDs on these APs may restart.
Get Configuration from another folder/group. The service impact depends on which settings at the current location change because of the operation. APs or the SSIDs on these APs may restart.
Monitor > WiFi > Radios > Turn Off Radio - All SSIDs on the radio are turned off.
Customize or Inherit Configuration at a Location The service impact depends on which settings at the current location change because of the operation. APs or the SSIDs on these APs may restart.
Move AP to another location The service impact depends on which settings at the current location change because of the operation. APs or the SSIDs on these APs may restart.
Troubleshoot > Packet Trace Enable or disable packet trace on an SSID. SSIDs for which auto packet trace is enabled or disabled will restart.

Checkpoints

 

You can create checkpoints to save your current configurations, profiles and settings. Creating and restoring a checkpoint is possible for all configuration settings available in CV-CUE. You can create a checkpoint for location based configurations, group configurations, or global configurations. For all the configurable settings that are available for a network, you can create a checkpoint to save it.

A checkpoint is a snapshot of your current settings and configurations.You can use this checkpoint to view your configuration details, compare your current configurations with a previous instance, or to restore your configurations to a particular set of settings. In case of a network failure or performance degradation, you can restore a previously created checkpoint to go back to the previous working state.
Note: This is a Beta Feature.
This chapter contains the following topics:

Types of Checkpoints

 

There are 3 kinds of checkpoints:

  • Location Checkpoint

    Location checkpoint saves all your SSID configurations, network policies, device configurations, WIPS policies, Mesh profile, and other settings of the selected location.

  • Group Checkpoint
    Group checkpoint captures the device configurations, custom device settings, and enabled SSID and Mesh profiles for a group.
    Note:

    Group checkpoint only captures which SSIDs and Mesh profiles have been enabled for the group, the actual SSIDs and Mesh profiles are not part of the checkpoint. Thus, restoring a group checkpoint restores the Enabled or Disabled state of SSIDs and Mesh profiles for that group. However, if the configuration of the SSID or Mesh profile was changed, the changed configurations are not restored.

  • Global Checkpoint

    Global checkpoints save configurations for all locations and groups, along with global policies such as WIPS, Advanced Settings, and third-party server policies.

Create Checkpoints

 

The ability to create a checkpoint is available on the following UI screens:
  • Configure > WiFi
  • Configure > Device
  • Configure > Network Profile
  • Configure > WIPS
  • Configure > Alerts
  • System > Navigator
  • System > Third Party Server
  • System > WIPS
  • System > Logs
  • System > User Accounts

Create a Location or Group Checkpoint

The option to create a location or group checkpoint is available in all configuration options under the Configure menu.

To create a location or group checkpoint:
  1. Select your location or group from the Navigator.
  2. Go to Configure > WiFi or any Configure option.
    Note: Note: You cannot create a location checkpoint at the root location.
  3. Click Create Checkpoint from the three-dot more menu.
  4. Provide a name and a brief description for the checkpoint and click Create.

Create a Global Checkpoint

The option to create global checkpoint is available in all screens available under the System menu. You can create a global checkpoint by clicking Create Global Checkpoint from the three-dot more menu.



You can also create a global checkpoint from any CONFIGURE screen by selecting the root location in the location tree.

Create Global Checkpoint in MSU Setup

For MSU setups, navigate to the parent server and click Create Checkpoints for all Servers to create checkpoints for the parent and all child servers simultaneously.

Note: For MSU setups, global checkpoints are server specific. You need to create a separate global checkpoint for each server.

View Checkpoints

 

Just like Create Checkpoint, the option to view your created checkpoints is available on all Configure screens in the three-dot more menu. Navigate to your location or group to view all the checkpoints available for that particular location or group. You can view your global checkpoints from any of the screens available under the System menu or by selecting the root location in the location tree.
You can perform the following actions on your created checkpoints:
  • Edit
  • Delete
  • Download - Displays a downloadable json file of your configuration details
  • Compare
  • Restore

Compare Checkpoints

 

You can compare two checkpoints to identify the delta in the configurations. To compare the checkpoints, select the two checkpoints to compare from the View Checkpoint table and click Compare.

A new tab displaying the differences in the JSON files of both the checkpoints opens.

You can also compare the checkpoint with your current configuration.

Restore Checkpoints

 

You can restore your configurations and settings to an earlier created checkpoint. When you restore a checkpoint, all the settings and configurations are changed to that of the saved checkpoint. If a location is inheriting a policy from its parent or is using an inherited profile, the checkpoint only captures the inheritance information and not the actual profile or policy. When you restore such a checkpoint, the policy is inherited again from the parent. If the inherited policy or profile is changed, the changed settings are not restored.

Non-restorable checkpoints

You cannot restore global checkpoints. Checkpoints also become non-restorable if any of the referenced configurations are deleted. For example, consider an SSID profile inherited by a child location. If you delete the SSID profile from the parent location, the checkpoint created on the child location becomes non-restorable.

You can use global and non-restorable checkpoints to perform view and compare operations.
