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 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 opt 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-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. |

New and Enhanced Features for Cisco IOS XE 17.15.x
New and Enhanced Software Features in Cisco IOS XE 17.15.1
Note |
Cisco IOS XE 17.15.1a is the first release for Cisco Catalyst 8000V in the Cisco IOS XE 17.15.x release series. |
|
Feature |
Description |
|---|---|
|
AWS Local Zones (LZs) enable you to deploy latency sensitive applications closer to end-users. Starting with Cisco IOS XE 17.15.1a, you can deploy Cisco Catalyst 8000V on c5d.2xlarge instances available in AWS Local Zones. |
|
|
From Cisco IOS XE 17.15.1a, you can set an interface speed of upto 40000 in Cisco Catalyst 8000V. This enables some traffic profiles to see higher throughputs. |
|
|
From Cisco IOS XE 17.15.1a, you can deploy Cisco Catalyst 8000V on RedHat RHEL 9.2 operating system with KVM hypervisor. Note that support for RHEL 7.x is deprecated from this release. |
|
|
From Cisco IOS XE 17.15.1a, you can deploy Cisco Catalyst 8000V on SUSE Linux® Enterprise Server 15 SP5 operating system with KVM hypervisor. |
|
|
From Cisco IOS XE 17.15.1a, you can deploy Cisco Catalyst 8000V on VMware ESXi 8.0 Update 2 hypervisor operating system. Note that ESXi hypervisor version 6.0 will no longer be supported from this release. |
|
|
The File Transfer using HTTP or HTTPs feature allows you to copy files from a remote server to your local device, using the copy command. From Cisco IOS XE 17.15.1a, you must provide the absolute file path when you execute the copy command, to transfer the file. |
|
|
From Cisco IOS XE 17.15.1a, this feature provides the ability to define and configure a new single Cisco Umbrella credential for both Umbrella SIG and Umbrella DNS. |
|
|
Cisco DMVPN (Dynamic Multipoint VPN) is a routing technique to build a VPN network with multiple sites without having to statically configure all devices. This technique uses tunnelling protocols and encrypted security measures to create virtual connections, or tunnels, between sites. These tunnels are dynamically created as needed, making them both efficient and cost-effective. |
|
|
Configure Multiple WAN Interfaces on Cisco SD-Routing Devices Using a Custom VRF |
You can now create a custom VRF that hosts one or more WAN interfaces. You can extend this functionality to create multiple custom VRFs with each VRF hosting multiple WAN interfaces. These WAN interfaces now function as transport interfaces to establish control connections to the Cisco Catalyst SD-WAN Manager. Having multiple WAN interfaces ensures that there is resiliency in control connections and routing of transport traffic. |
|
Configure Site-Cloud Support to AWS Using Configuration Groups |
This release introduces support to configure site to cloud connectivity from an SD-Routing branch to Amazon Web Services using Configuration Groups. This is an enhancement over the existing implementation of configuring site to cloud connectivity from an SD-Routing branch to Amazon Web Services using CLI-Add on Profile. |
|
Enabling Flow Level Flexible NetFlow Support for SD-Routing Devices |
The Flow-level Flexible NetFlow (FNF) feature allows you to monitor the NetFlow traffic and view all the flow-level FNF data that is captured including application-level statistics. |
|
From Cisco IOS XE 17.15.1a, the Enhanced NAT Management feature enables network operators to safeguard system performance by limiting NAT translations based on CPU usage with the ip nat translation max-entries cpu command. This feature also enables streamlining NAT synchronization in redundant systems using the ip nat settings redundancy optimized-data-sync command. |
|
|
From Cisco IOS XE 17.15.1a, Segment Routing over IPv6 dataplane supports these functionalities: |
|
|
From Cisco IOS XE 17.15.1a, network administrators can monitor SD-Routing device alarms on Cisco Catalyst SD-WAN Manager. This feature enables SD-Routing devices to record and store various alarms generated by control components and routers. For more information, see Cisco SD-Routing Command Reference Guide. |
|
|
Network-Wide Path Insights on Software Defined (SD) - Routing Devices |
Network-Wide Path Insights (NWPI) is a tool that allows network administrators to monitor Cisco SD-Routing deployment, identify network and application issues, and optimize the network. |
|
SD-Routing License Management |
This release introduces license management support for SD-Routing devices. The supported licensing workflows include license assignment or configuration, license use, and license usage reporting. Depending on the device, these workflows are performed in the Cisco Catalyst SD-WAN Manager or on the device. |
