Initial setup (first boot) of CVA

The first time CVA 7 boots up it uses a console based setup program called “firstboot” to set up basic appliance parameters like IP addresses and initial admin passwords. These can later be changed via the CLI, GUI or REST API.

The firstboot setup program is available in the following ways:

On the serial console
Via the integrated management (iDRAC) of the appliance
On the physical console (Video ports) of the appliance

Upgrade from existing CVA

Upgrade from CVA 6 or before

Direct upgrade from CVA 6.x to 7.2.0 is not supported. To upgrade from CVA 6, please first perform the upgrade to CVA 7.1.1 (see TOI - Framework to upgrade from legacy CVA) and then proceed with a subsequent upgrade to CVA 7.2.0 by following the steps below.

Upgrade from CVA 7 or later

Upgrading CVA involves one or more reboots. It is highly recommended to have remote console (e.g. iDRAC) and physical access ready in case recovery becomes necessary.

1. Download the new CVA ISO image (e.g. cva-7.2.0.iso) from the Software Download page on arista.com.

2. Copy the new CVA ISO image onto the to-be-upgraded CVA using one of the following methods (2a - 2d).

2a. SCP (executing the scp command from any other machine)

On the machine that carries the new CVA ISO image, run:

scp <file> admin@<cva-ip>://image

Example:

scp cva-7.2.0.iso 该邮件地址已受到反垃圾邮件插件保护。要显示它需要在浏览器中启用 JavaScript。://image

2b. SCP (executing the copy command from CVA)

enable
copy scp://<user>:<password>@<host>/<iso-image-path> image://

Example:

enable
copy scp://root:该邮件地址已受到反垃圾邮件插件保护。要显示它需要在浏览器中启用 JavaScript。/cva-7.2.0.iso image://

2c. HTTP/HTTPS URL (via the CLI)

enable
copy <url-to-iso> image://

Example:

enable
copy https://192.0.2.101/cva-7.2.0.iso image://

ignore-ssl-certificate can be optionally used (i.e. appended to the end of the copy command) if the HTTPS server presents a self-signed certificate or a private CA certificate.

2d. HTTP/HTTPS URL (via the GUI)

In the CVA Web UI, go to the Maintenance > Upgrade page.
It should land you at the Images tab by default.
Click Copy Image to import the CVA ISO image using an HTTP/HTTPS URL.

3. Go to the GUI and in the Images tab locate the image that has just been imported.

4. Click Upgrade and follow the instructions to complete the process. The CVA reboots into the new version upon a successful upgrade.

Setting up CVP on CVA 7

… via the GUI

Login to the CVA 7 Web UI at https://<cva-ip-address> on your web browser
Click Add Package to import a CVP atswi image into this CVA 7 instance

e.g. CloudVision > CloudVision Portal > Active Releases > 2026.1> 2026.1.1 > cvp-2026.1.1.atswi

The file can be uploaded by selecting (or drag-and-drop) a file to upload via the browser:

Alternatively, if hosted on a web server, the URL can be used to import the CVP atswi image:

When a package has already been added, additional packages may be added under Sources > Actions > Add Package:
Click Submit and wait for the import to finish
When import is complete, close the Background Tasks drawer
Click Add Application
Select the CVP/CVX package and version imported just now, then click Next
Set the Desired State to Running, then click Submit

Optional: An ISO-based Configuration file may be specified to automatically provision the new instance of CVP. The ISO file can be imported via the ISO-based Configuration tab in the UI.

Optional: the resource allocation strategy may also be selected at this point to determine the vCPU and memory allocation the VM receives. The allocation may also be updated after deployment (this requires a VM reboot), please see Managing the VM Resource Allocations on CVA 7 for further details.
The CVP application is now being deployed
The CVP application is now running. However, CVP does not have any IP addresses yet (unless the instance has already been provisioned with the ISO-based configuration above). Click Details to follow-up on that.
Click Connect to the CloudVision Appliance CLI via SSH
Now you are in the CVA 7 CLI
Run enable; connect application cvp (copied and pasted from the CVA 7 Web UI above) to connect to the CVP console
Login as cvpadmin and follow the prompts to set up CVP. A sample output can be found at:
The IP address of CVP is now shown in the CVA 7 Web UI. Click the IP address to go to the CVP UI

Step 3: Create an app deployment

enable
config
application <deployment name>
package-checksum <checksum-from-above>

Step 3.A: (optional) ISO-based configuration

An ISO may also be optionally specified at this stage to configure the CVP deployment using CVP’s ISO-based configuration. To do this, the ISO must be uploaded via the GUI or the CLI commands below:

enable
copy <cvp-iso-url> userdata://<ISO name>

The imported ISO may then be configured as shown below:

provisioning-userdata <ISO name>

Step 3.B: (optional) Configure a resource allocation strategy

A resource allocation strategy may be configured or can be omitted in order to use the package provided default. The allocations strategy can also be updated after app deployment but requires a resource reallocation which involves an app reboot.

strategy cvp-with-cvx

Step 4: Deploy and run the app

Once the deployment config has been added, the app can be deployed by setting the desired-state to running:

desired-state running

Following completion of these steps, the deployment process will begin. The app state can be monitored via the show application command as shown in the Introduction to the CVA 7 CLI section below.

Setting up CVX on CVA 7

To deploy CVX, please import a CVX atswi as shown for CVP in the section above. CVX may be deployed following the same procedure as for CVP in GUI steps 1 - 9 and CLI steps 1 - 4.

The example below shows the deployment steps for CVX via the GUI.

Select the CVX package
Configure and deploy the CVX application
Wait for the configured Desired State to be reached

If CVX is deployed alongside CVP, please ensure the relevant co-operative resource strategies “cvx-with-cvp” and “cvp-with-cvx” are in use (for each respectively). Failure to do so may prevent deployment from proceeding as shown below:

To proceed with deployment, please configure the correct strategies and trigger reallocation (of CVP) via Reallocate Resources as indicated via the error below:

Following reallocation, the resource required to run CVX will be reclaimed from CVP and allow the CVX deployment to proceed:

Managing VM Resource Allocation on CVA 7

CVA 7.1.0 added functionality to manage the resource allocations for the deployed VMs via the REST API (with GUI and CLI support). This feature allows the memory and vCPU allocation to be configured for each VM. Overallocation of resources with multiple VMs or exceeding the host resources is not supported.

The system tracks two types of resource allocations:

Computed Allocation: The latest resource allocation computed for the application based on the selected strategy. When a new strategy has been selected, this represents the allocation the application will receive following reallocation or fresh deployment.
Deployed Allocation: The resource allocation currently in use by the deployed application. For applications not yet deployed, no allocation is reported.

Please see the sections below for instructions on using this feature and inspecting the allocations above in the GUI and CLI. Further details on the available strategies can be found in the Resource Allocation Strategies section.

… via the GUI

Configuring resource allocation during deployment

During initial app deployment the allocation strategy may be selected as shown below:

When strategy “manual” is used, further options are provided to enter the exact VM specs:

Updating the resource allocation after deployment

Following app deployment, the strategy may be updated by selecting Edit Application and selecting a new strategy using the menu shown above.
Once the config has been submitted, the app will receive a new resource allocation. The mismatch between the available allocation and currently used allocation is reported as an error indicating “Updated allocation detected. Reallocate required.”
To update the deployed VM to receive the new allocation, a reallocation must be manually triggered. During this time, the application will continue to run with the prior allocation. The incoming newly computed allocation may be inspected and compared with the existing deployed allocation via View Details (shown in the bottom right):
To update the application to receive the new allocation, trigger a reallocation via Reallocate Resources
Reallocation will orchestrate the necessary VM shutdown and update its configured resources
Following reallocation, the VM will be returned to its prior Desired State and the deployed allocation will be updated

… via the CLI

Configuring the resource allocation during deployment

The resource allocation strategy may be configured during app deployment using the strategy command (when in the config-app submode). Tab completion can be used to reveal the list of available strategies provided by a package and their descriptions.

 maximum                                             The maximum available resources. If resources are in use for other applications, this is not guaranteed to meet or exceed the recommended. If the minimum is unmet, an error will be reported. The maximum available resources may be configured for one application only.
 package-default                                     The default allocation strategy for the CVP atswi. The default maps to "maximum".

Step 4: To update the application to receive the new allocation, trigger a reallocation via reallocate application <deployment name>:

cva1(config-app)# reallocate application cvp
None.

Step 5: Reallocation will orchestrate the necessary VM shutdown and update its configured resources:

cva1(config-app)# show application

Resource Allocation Strategies

For CVA 7.2.0, the supported strategies and their corresponding allocations are listed in this section. Resource allocation strategies are provided by the atswi package and may therefore be updated independently of CVA such that the values provided here are not guaranteed to be accurate for newer atswis.

Recommended Minimum Allocations

For all of the strategies below, the resulting allocation must meet the recommended minimum for the application. When the recommended minimum is not met, a warning is reported. Deployment in this scenario is not blocked but is not advised as the application may experience degraded performance. The recommended minimum allocations are:

CVP: 52 GiB memory and 28 vCPUs
CVX: 4 GiB memory and 4 vCPUs

Common Strategies

These strategies may be configured for either CVX or CVP.

Manual
Allows users to manually configure resource allocations for both the memory and CPU allocation. Custom specifications must meet the application's recommended requirements or a warning is reported.

Maximum
Automatically allocates all available system resources. If resources are in use by other applications, the allocation may not meet the recommended. Only one application can use maximum allocation at a time.

CVP Strategies

These strategies are applicable to CVP only.

Package Default
The default allocation strategy for CVP. This maps to the "maximum" strategy.

CVP with CVX
The recommended resource allocation for CVP deployments running alongside CVX. These allocations reserve sufficient resources for a CVX deployment. The exact values are shown in the table below.

SKU	Memory (GiB)	vCPUs
DCA-200	52	32
DCA-250	52	32
DCA-300	52	40
DCA-350	114	70
DCA-400	52	40
DCA-450	235	84

CVX Strategies

These strategies are applicable to CVX only.

Package Default
The default allocation strategy for CVX. This corresponds to 8 GiB memory and 8 vCPUs.

CVX with CVP

The recommended resource allocation for a single CVX deployment running alongside CVP. This corresponds to 5 GiB memory and 6 vCPUs. This allocation leaves sufficient resources for a CVP deployment.

Introduction to the CVA 7 CLI

Mode and sub-modes divide CLI commands, which restrict commands to the appropriate context. The main modes and their available commands are as follows:

login mode: commands available immediately after logging in, with the broadest possible context.
enable mode: commands that are available only after entering the enable command.
config mode: commands that significantly affect system configuration and can only be entered after entering the configure command. The user can also access submodes from this mode.

Enter submodes from config mode to provision specific monitoring fabric objects. For example, the application <app-name> command changes the CLI prompt to (config-app)# and lets the user configure the application identified by the given name.

When the user logs in, the CLI appears in login mode, where the default prompt is the system name followed by a greater than sign (>), as shown below:

cva1>

To change the CLI to enable mode, enter the enable command. The default prompt for enable mode is the system name followed by a pound sign (#), as shown below:

cva1> enable
cva1#

To change to config mode, enter the configure command. The default prompt for config mode is the system name followed by (config)#, as shown below:

cva1> config
cva1(config)#

To change to a submode, enter the command from config mode, followed by any object identifier required, as in the following example:

cva1(config)# application cvp
cva1(config-app)#

To return to enable mode, type end, as shown below:

cva1(config)# end
cva1#

To view the path to the current CLI prompt, enter the show this command from any nested submode, as in the following example:

cva1(config-app)# show this

! application
application cvp
  desired-state running
  package-checksum 0cfe8afd32391dca9ad95ba031076f8fae2969641392cc0f3cf9511a7c6a1ab3
  provisioning-userdata userdata://node1-cvp_10_243_253_101.iso
cva1(config-app)#

To view details about the configuration, enter the show this details command, as in the following example:

cva1(config-app)# show this details

! application
application cvp
  desired-state running
  no reconcile-version
  package-checksum 0cfe8afd32391dca9ad95ba031076f8fae2969641392cc0f3cf9511a7c6a1ab3
  provisioning-userdata userdata://node1-cvp_10_243_253_101.iso
cva1(config-app)#

To view a list of available commands in the current or submode, enter the help command.

Protocol Access Required For CVA

You can control access to CVA for specific protocols, and in the case of SSH, you can allow access only from specific IP addresses or subnetworks. The following table summarizes the TCP/UDP protocol ports that CVA uses. The CLI access-list option column shows the options for the ports that can be enabled or disabled using the CLI access-list command (config-controller-access submode entered via cluster; access-control). The ports listed are open by default on CVA, except for SNMP, which is disabled by default.

These ports must also be open on any device, such as a router or firewall, that connects the management console or application to CVA.

Protocol	Port	Application	CLI access-list option	Match criteria
HTTP	TCP 80	GUI auto-redirect
HTTPS	TCP 443	GUI remote access	gui	Default any, configurable
HTTPS	TCP 8443	REST API	api	Default any, configurable
ICMP/ICMPv6	ICMP/ICMPv6			Selected ICMP types
ICMP/ICMPv6	ICMP/ICMPv6			Selected ICMP types
SNMP	UDP 161, 162	SNMP	snmp	Default none, configurable
SSH	TCP 22	CLI remote access	ssh	Default any, configurable
syslog	UDP 514
vce-api	UDP 7443	vCenter integration	vce-api	Enabled by default

Note: Be careful when configuring firewall rules for the SSH protocol, which is permitted from all subnetworks by default. The option exists to restrict SSH access to one or more specific subnetworks. However, this denies access from all other subnetworks. If no connectivity from a specified subnetwork is available, accessing the Controller is only through the local console.
