Cisco Catalyst 8000V Edge Software Overview
About Cisco Catalyst 8000V
Cisco Catalyst 8000V Edge Software or Cisco Catalyst 8000V is a software-based, virtual router that combines the functionalities of Cisco Cloud Services Router (Cisco CSR1000V) and Cisco Integrated Services Virtual Router (Cisco ISRv) into a single image that is intended for deployment in on-prem branches, data centers, colocation data centers, and public clouds.
Cisco Catalyst 8000V supports NIM modules on Cisco ENCS platforms, runs on any x86 platform, and is supported on ESXi, KVM, NFVIS hypervisors. Further, you can deploy this router on public cloud providers such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Alibaba Cloud.
When you deploy Cisco Catalyst 8000V as a VM, the Cisco IOS XE software behaves similar to a traditional Cisco router (hardware platform). You can configure different features depending on the Cisco IOS XE software version.
Features
-
Hardware independence: The Cisco Catalyst 8000V router uses the benefits of virtualization in the cloud to provide hardware independence. Since the Cisco Catalyst 8000V runs as a virtual machine, you can use this router on any x86 hardware that the virtualization platform supports.
-
Sharing of host hardware resources: The host server hardware resources such as CPU cores, memory, and disk are managed by the hypervisor, and these resources are shared among the guest VMs. You can regulate the amount of hardware resources assigned to a specific Cisco Catalyst 8000V VM instance.
-
Flexibility in deployment: You can easily move a VM from one server to another. Thus, you can move a Cisco Catalyst 8000V instance from a server in one physical location to a server in another physical location without moving any hardware resources.
-
Enhanced software security - Secure Object Store: In Cisco Catalyst 8000V, storage partitions for NVRAM, licensing, and other data are created as object stores. The individual object stores are encrypted to ensure data security, and this product is Cisco Secure Development life cycle (CSDL) compliant. Further, Cisco Catalyst 8000V supports a 16G disk cycle profile.
Hardware Requirements
For hardware requirements and installation instructions, see the Cisco Catalyst 8000V Edge Software Installation And Configuration Guide.
Software Images and Licenses
The following sections describe the licensing and software images for Cisco Catalyst 8000V.
Cisco Catalyst 8000V Software Licenses
The Cisco Catalyst 8000V is licensed based on throughput, feature-set, and the licensing term. This product supports Cisco Smart Licensing Usage Policy as well as Cisco DNA Licensing. Based on whether you want to go for purchased licenses that go with the Cisco Catalyst 8000V instance, or a subscription-based license, choose one of the following options:
Subscription-Based Licensing via Cisco DNA
You can purchase a subscription license for Cisco Catalyst 8000V through the following three licenses that are available via Cisco DNA:
-
Cisco Catalyst 8000V - Network-Premier
-
Cisco Catalyst 8000V - Network-Advantage
-
Cisco Catalyst 8000V - Network-Essentials
For more information on Cisco Catalyst 8000V DNA licensing, see Cisco DNA Software for SD-Wan and Routing Ordering Guide.
Bring-Your-Own-Licensing
You also have an option to purchase and use licenses with Cisco Catalyst 8000V as a Bring-Your-Own-License (BYOL) instance or as a Pay-As-You-Go (PAYG) instance.
To use a Cisco Catalyst 8000V - BYOL license, see Licenses and Licensing Models to know to how install and configure your license.
If you have upgraded to Cisco Catalyst 8000V from a Cisco CSR 1000V or a Cisco ISRV, you must use Smart Licensing Using Policy (SLP). Traditional licenses do not work after the upgrade.
Pay-As-You-Go Licensing
Cisco Catalyst 8000V supports the PAYG Licensing model with Amazon Web Services (AWS) and Microsoft Azure Marketplace. Cisco Catalyst 8000V hourly-billed AMI or Pay As You Go licensing model allows you to consume an instance for a defined period of time. In this licensing model, you can directly launch the instance from the AWS or Azure Marketplace and start using the instances. The licenses are embedded in the image.
Note |
For demo or evaluation licenses, contact your Cisco Account Team if you have a direct purchase agreement with Cisco, or your Cisco Partner or Reseller. |
For a more detailed overview on Cisco Licensing, go to https://cisco.com/go/licensingguide.

New and Changed Software Features in Cisco IOS XE 17.6.1a
Note |
Cisco IOS XE Bengaluru 17.6.1a is the first release for Cisco Catalyst 8000V in the Cisco IOS XE Bengaluru 17.6.1 release series. |
The following are the new Cisco Catalyst 8000V software features for Cisco IOS XE Bengaluru Release 17.6.1a:
Feature |
Description |
---|---|
Earlier, when you deployed Cisco Catalyst 8000V on Amazon Web Services, only version 1 or V1 was applicable for the Metadata Accessible field. Starting from Cisco IOS XE Release 17.6.1a, metadata version 2 or V2 is also supported. Now, you can either select the V1 and V2 (token optional) option or the V2 (token required) option. When you select either of these options, the instance uses session-oriented requests by creating tokens. The tokens are then used to fetch all the required metadata for your instances. |
|
Automatic Mapping of Cisco CSR 1000V or Cisco ISRv Licenses to DNA Tier Licenses |
The Cisco Smart Software Manager (CSSM) manages licenses of all the Cisco devices including Cisco CSR 1000V and Cisco ISRv, which have an end-of-life milestone of year 2022. To continue to keep your Smart Account active, it is mandatory to move to Cisco DNA tier-based licenses. After you activate your Cisco DNA license, CSSM automatically maps the device licenses (CSR 1000V or Cisco ISRv) to your Cisco DNA tier license. |
Support for ESXi 7.0 |
Cisco Catalyst 8000V supports ESXi 7.0 and 6.7 from Cisco IOS XE 17.6.1a. Note that support for ESXi 6.5 has been deprecated. |
The Zone-Based Firewall (ZBFW) Policy Reclassification feature is an enhancement to the Zone-Based Firewall feature. With this enhancement, any changes you make to the policy configuration on an existing firewall session is immediately enforced. |
|
This feature allows you to manage or change the lease renewal. It provides options to force renewal of lease and also detects when the lease is nearing the expiry date. |
|
Upgrade to pyang version 2.x |
The updated pyang plugin version 2.x fixes existing issues such as XPATH validation and upstream pyang issues. Additionally, this version reports all errors in the YANG models to the users and enforces a strict model validation. |
From Cisco IOS XE Bengaluru 17.6.1, CUBE can use WebSockets to handle media forking in a Cisco Unified Contact Center Enterprise (UCCE) solution deployment with Cloud Speech Services. WebSockets transport multiple media streams over a single reliable TLS connection that may traverse firewalls without the need for special policies. WebSocket traffic is also compatible with HTTP load balancers and proxies. |
|
From Cisco IOS XE 17.6.1 onwards, CUBE can transcode Opus encoded media streams. Because Opus codecs perform very well over the Internet, this feature is particularly beneficial when routing calls between the PSTN and Cloud calling services. See also https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/ios-xe/config/ios-xe-book/m_transcoding.html. |
|
YANG models were developed for the following CLIs as part of the Class of Restriction configuration:
|
Feature |
Description |
---|---|
Snapshots for PAK Licenses |
The library that manages product activation key (PAK) licenses is being deprecated from the software image. To continue supporting and honouring any existing PAK licenses you may have, the system automatically takes a snapshot of the PAK license and triggers a Device-Led Conversion process, to convert the PAK license to a Smart License. For the system to take the snapshot, the software version running on your device must be one of the required releases. For information about the releases in which the system can take a snapshot, and the options that are available with respect to the device and the license, see Snapshots for PAK Licenses. |
Note |
From Cisco IOS XE Bengaluru 17.6.x, configuring a weak crypto algorithm generates a warning. But this warning can be safely ignored and does not impact the working of the crypto algorithms. For more information on weak crypto algorithms, see Supported Standards. |
