What's New in this Release

This chapter describes features that are new in the 18.0 release of CloudVision Cognitive Unified Edge (CV-CUE).

Operations

LAN2 Port as Uplink Port

Access Points (AP) can also use LAN2, along with LAN1, as the Uplink Port. If LAN1 and LAN2 are connected and LAN1 fails to receive any packets, the AP can fail over to LAN2 as the Uplink Port and will continue to operate on the same uplink even if LAN1 is active again. The AP will switch to LAN1 again as the Uplink only when LAN2 is inactive or disabled.

AP Platforms Supporting this Feature: C-250/C-260, C-330, C-360, C-460, C-460E Series.

Customize SSID Attributes for Location Specific Overrides

Administrators can override certain attributes of an SSID at a child location without breaking the inheritance, so the entire SSID configuration remains the same except for the overridden attributes.

VLAN Pooling in SSID Settings

Network Administrators can define a VLAN Pool in SSID Settings, which is a list of VLAN IDs for Access Points (AP) to distribute to clients connecting to the SSID. VLAN Pooling offers better scalability and optimized load-balancing of traffic.

RADIUS Pooling in SSID Settings

RADIUS Pooling lets Network Administrators assign a pre-defined list of RADIUS Servers that Access Points (AP) can use to authenticate, authorize, and maintain clients' accounts. It offers better load-balancing capabilities and improved scalability.

Reject Clients Using Locally Administered MAC Addresses

Network Administrators can prevent clients that use locally administered MAC addresses from accessing your network. This feature ensures that only clients that use their device’s globally unique MAC addresses can connect to the network.

On-Demand Transmit Power Control and Auto-Channel Selection

Network Administrators can start the Auto-Channel Selection (ACS) Mode and Transmit Power Control (TPC) Mode for a radio on demand. In ACS Mode, the Access Point (AP) scans the network to select the best channel. In Auto-TPC Mode, the AP automatically adjusts its transmit power to minimize interference with neighboring Arista APs.

Monitoring and Troubleshooting

Timer-Based Window to Onboard Access Points After Changing the Communication Key

When Network Administrators change the AP-Server Communication Key, some APs may fail to connect to the server. Administrators can enable the onboarding window from CV-CUE and allow such APs to connect using the Default Key or the Old Key.

Third-Party Integrations

Google Chat and Microsoft Teams Webhook for Feed

Along with Slack, Network Administrators can configure Google Chat and Microsoft Teams Webhook to receive alerts whenever a network issue or anomaly is detected.

Forward Client DHCP Packets to Destination Servers

Send a copy of DHCP Packets from Access Points (AP) to Network Access Control (NAC) solutions for profiling clients and assigning appropriate network segments.

Managing Navigator

Navigator enables you to define a hierarchical structure to organize how your WLAN network is deployed. This hierarchical structure can be based on any criteria, such as the location where the APs are deployed, the organizational departments using a set of APs, Test vs Production network, and so on.

Navigator comprises of folders and floors. Folders can represent any logical grouping such as departments of an organization, business units, physical locations such as country, city, and building, and so on. Floors can represent a more granular level of deployment such as a group using a common set of access points, or a physical location such as a floor in a building where the access points are deployed. For example, Hawaii Conference Room, Bldg 15-Cubicle G2, or Executive Area.

Click System to view, edit and manage the hierarchy of folders and floors. Only a Superuser, Administrator, and Operator user can edit Navigator. Users with the Viewer role can only view the Navigator.

The following figure shows the Navigator. Right-click on a folder or a floor to perform various tasks and edit the Navigator.

This chapter contains the following topics:

Add a Folder or Floor
Add Multiple Folders or Floors
Delete Folders and Floors
Rename Folder or Floor
Search Folder or Floor

Introduction to Groups

Add a Folder or Floor

You can add one or more folders under the root folder or under other folders. You cannot add a folder or a floor to the Unknown folder. Only Superuser, Administrator, and Operator can add a folder or a floor. A Viewer can only view the Arista Navigator.

To add a folder or floor, perform the following steps:

Click System.
Select a folder under which you want to add a new folder or floor. Right-click and select Add a Folder/Floor.
Select Folder to add a folder or select Floor to add a floor.
Type the name of the folder or floor and click Add.
Important: You cannot add a folder or floor under a floor.

Add Multiple Folders or Floors

You can add multiple folders and floors at the same time. You can add multiple folders under the root folder or other folders. You can add multiple floors under a folder. You cannot add folders or floors under the Unknown folder.

To add multiple folders or floors, perform the following tasks:

Click System.
Right-click a folder under which you want to add multiple folders and floors and select Add Multiple Folders/Floors.
Type the folder and floor names in the given text area that you want to add. You can have only one name per line.
To create a hierarchy of folders and floors, use the Tab key. A sample hierarchy of folders and floors would look like this:

Important: Prefix * to make a floor. You cannot add a folder or floor under a floor.
Click Add.

Delete Folders and Floors

Use this feature to get rid of unwanted and redundant folders and floors that are not applicable.

To delete the folders or floors, perform the following tasks:

Click System.
Select the folders and floors that you want to delete.
Right-click any of the selected folder or floor and select Delete.
Click Delete to confirm the deletion.

Important: Alternatively, you can also the delete the folders and floors in a similar manner using the delete icon located above the hierarchy of folders and floors.

Rename Folder or Floor

Use this feature to change the name of a single or multiple folders or floors.

To rename a file, perform the following tasks:

Click System.
Select the folders and floors that you want to rename.
Right-click any of the selected folder or floor and select Rename.
Do the required changes and click Rename to save the changes.

Important: You can also the rename the folders and floors in a similar manner rename icon located above the hierarchy of folders and floors.

Search Folder or Floor

You can type a string of letters or the name of a folder or floor to locate it on the Navigator.

To search a folder, perform the following tasks:

Click System.
Enter the text substring matching the name of the folder or floor in Search Folders/Floors text box. The folders or floors matching the pattern of the text string or substring is displayed along with the parent folder.

Note: Pattern-based search with the use of special characters, such as * and ? is not supported.

Set Timezone for Folders

Set the appropriate time zone for the selected folder using the System > Navigator page. Only a Superuser, Administrator, and Operator user can configure the location time zone for a location.

The time zone settings help in accurate analytics. Ensure that you select the correct time zone for the selected folder.

Important: You cannot set a time zone for a floor. The time zone set for the immediate parent folder of a floor applies to the floor.

To set the timezone for a folder, perform the following tasks:

Go to System > Navigator.
On the Navigator page, right-click the folder name and select Set Timezone.
Select the appropriate timezone from the drop-down list and click Set.

Important: You can also set the timezone in a similar manner using the Set timezone icon.

Set Location Tag

To assign a location tag to a folder or floor, perform the following steps:

Go to System > Navigator > Folders/Floors.
Right-click the folder or floor to which you want to assign the tag.
On the right-click menu, select Location Properties > Location Tag.
In the Location Tag window, enter the location tag and click Set.
Select Apply recursively to subfolders if you want the same location tag to be used by child locations. When selecting this option, keep in mind that mDNS gateways return devices based on the location tag.
Note: mDNS Packet Tagging uses the location tag to help Wi-Fi clients locate network services such as printers. When assigning the location tag, note the following:
- Arista mDNS gateways truncate the location tag to the first 128 characters.
- We recommend that you use only numbers, letters, and hyphens in the location tag because Arista switches do not support special characters in mDNS tags.

Introduction to Groups

Until now CV-CUE allowed users to configure only the Wi-Fi configuration for a selected location. You could not do custom configuration on a device or a set of devices. To overcome this restriction, Groups have been introduced in CV-CUE.

Groups will facilitate faster customization of Arista APs by allowing you to apply custom configuration (for example, SSIDs, Radio Settings, and Device Settings) to APs located across different branches of a hierarchical location tree. A group will always have a unique name. You can access a group only if you can access the folder where the group was created. A user who does not have access to a group can view devices in that group, but cannot perform actions such as rename or delete.

After the group is created, you can configure it. You can configure a group either by turning an SSID ON at the folder where the group was created, or by modifying the Device Settings or Radio Settings.

AP's in a configured group use the same configuration as the group. Moreover, each group has a single Wi-Fi configuration. APs which are not part of any group will continue to use the Wi-Fi configuration of the location on which they are created. When you delete a location, groups at the deleted location are deleted and devices assigned to the group will be moved to their parent location.

Note: An Arista device can be part of one and only one group at a time.

Add a Group

To add a group, perform the following steps:

Go to System > Navigator > Groups .
Click the Plus Icon to add a group.
Type a unique name for the group and click Add.
Note: The group name should be unique across all the available groups and folders.CV-CUE searches for a common root folder (Root) for all the locations that a user can access and accordingly creates a group at that folder. If a user does not have permissions on the root folder, then the group will be created at the next topmost folder to which a user has access.

Groups Actions

There are certain actions that can be performed on an individual group. The list of actions is:

Show Assigned Devices
Rename a Group
Delete a Group

Show Assigned Devices

This action results in showing the list of APs assigned to the particular group. Access Point listing would show columns: Name, MAC Address, Model, Group, and Location with the applicable filters. To know more in detail about the specified columns and applicable filters refer the topic Access Points.

Note: This action is not allowed for multiple groups.

To perform this action follow the below steps:

Go to System ->Navigator ->Groups.
Click on the three vertical dots next to the group for whom you choose to see the device list.
Select Show Assigned Devices option.

Rename a Group

You can change the name of a group, if required.

To rename a group, perform the following steps:

Go to System > Navigator > Groups.
Right-click on the name of the group you want to rename or click on the menu icon (three vertical dots) and click Rename.
Change the name of the group and click Rename to save the changes.

Delete a Group

Deleting a group would impact few of the functionalities:

If a group is deleted, devices assigned to that group will start using the default Wi-Fi configuration of their respective folders
Similarly, if you delete a folder, then the groups created under it will also get deleted. And the devices will start using the default Wi-Fi configuration of their respective folders.

To delete a group, perform the following steps:

Go to System > Navigator > Groups.
Right-click on the name of the group you want to delete or click on the menu icon (three vertical dots) and click Delete.
Click Yes.

API Sandbox

API Sandbox allows you to try and test out APIs in the API sandbox without altering the data in your production environment. API Sandbox allows you to test the features programmatically by invoking APIs in a test environment for the selected location.

You can create an API sandbox for any location. The API sandbox provides an environment that is a clone of the selected folder location.

Creating an API Sandbox

Navigate to SYSTEM > Navigator > Folders/Floors > right-click a folder location > Add API Sandbox.
Provide a name and description for the API Sandbox and click Create.

Executing APIs in the Sandbox

To try out the APIs in the sandbox:

Navigate to your location and click Show Available API Sandboxes.
Click your API sandbox. The API Sandbox portal opens.
Select your module and the API version number.
Click the Try it Out button next to the API you want to try.
Provide the required request parameters and click Execute.
