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 cloud and virtual data centers.
Cisco Catalyst 8000V supports NIM modules, 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 on a VM, the Cisco IOS XE software functions as if it were deployed on a traditional Cisco hardware platform. You can configure different features depending on the Cisco IOS XE software image.
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 on a virtual machine, you can use this router on any x86 hardware that the virtualization platform supports.
-
Sharing of resources: The resources used by Cisco Catalyst 8000V are managed by the hypervisor, and these resources can be shared among the VMs. You can regulate the amount of hardware resources that the VM server allocates to a specific VM. You can reallocate resources to another VM on the server.
-
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 Routing Subscription 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. |

-
c8000v-universalk9.17.10.01a.ova
-
c8000v-universalk9.17.10.01a.iso
-
c8000v-universalk9.17.10.01a.qcow2
The following table lists the filename attributes along with its properties:
|
Filename Attribute |
Properties |
|---|---|
|
universalk9 |
Specifies the package that you are installing. |
|
17.10.01a |
Indicates that the software image is mapped to the Cisco IOS XE Dublin 17.10.1a release. |
Product Field Notice
Cisco publishes Field Notices to notify customers and partners about significant issues in Cisco products that typically require an upgrade, workaround or other user action. For more information, see https://www.cisco.com/c/en/us/support/web/field-notice-overview.html.
We recommend that you review the field notices to determine whether your software or hardware platforms are affected. You can access the field notices from https://www.cisco.com/c/en/us/support/web/tsd-products-field-notice-summary.html#%7Etab-product-categories.
New and Enhanced Features for Cisco IOS XE Dublin 17.10.x
New and Enhanced Features for Cisco IOS XE 17.10.1a
Note |
Cisco IOS XE Dublin 17.10.1a is the first release for Cisco Catalyst 8000V in the Cisco IOS XE Dublin 17.10.x release series. |
|
Feature |
Description |
|---|---|
|
Cisco Catalyst 8000V supports ED25519 SSH key type for authentication when you deploy an instance in Amazon Web Services 9 (AWS) and Google Cloud Platform (GCP). Although SSH-RSA keys are supported in these cloud providers, we recommend that you use the ED25519 SSH key for generating and verifying the keys faster. Also, this provides better collision resilience and security. |
|
|
Cisco Catalyst 8000V now supports the ixgbe Network Interface (vNIC) card for deployments in ESXi, KVM, and NFVIS (CSP) environments. This driver enables the Peripheral Component Interconnect (PCI) passthrough feature that allows you to access and manage the hardware from a virtual machine. For more information, see Installing in KVM Environments and Installing in an NFVIS Environment. |
|
|
Using this feature you can configure to match the packets based on user defined field position and length. This can be used by an ACL to match packets that cannot be classified easily with the traditional Layer 3 and Layer 4 field information. |
|
|
Support for Secure Real-time Transport Protocol (SRTP) Dual-Tone Multi-Frequency (DTMF) Interworking |
This feature provides support for Dual-Tone Multi-Frequency (DTMF) interworking between Cisco Unified Communications Manager (CUCM) and Secure Software MTP in pass-through mode. It is supported on both CUCM and Cisco IOS XE software. |
|
Border Gateway Protocol (BGP) Ethernet VPN (EVPN) Virtual Extensible LAN (VXLAN) is a campus and data center network solution for Cisco devices that run on Cisco IOS XE software. This feature allows Layer 2 segments to be supported across an IP core therefore allowing improved scalability with infrastructure. It also provides all the benefits of Layer 3 topologies. |
|
|
Segment Routing Absolute One-Way Link Loss Measurement for GRE-IPSec Tunnel |
This feature provides a mechanism for link loss measurement for point-to-point GRE-IPSec tunnel and identifies paths that meet specified loss criteria. |
|
This feature provides support for SHA-2 as an additional authentication protocol to create an SNMPv3 user and associate a security level to each user. The SHA-256, SHA-384, and SHA-512 are the supported HMAC-SHA-2 protocols. You can configure the SHA-2 authentication protocol using a new keyword - sha-2 - in the snmp-server user command, and extend the authentication level from the existing MD5 and SHA protocols. For more information, see Cisco IOS SNMP Support Command Reference. |
|
|
Support for YANG Operational Model in the GETVPN architecture |
This feature enables the YANG operational model in the GETVPN architecture to support the crypto gdoi command which was previously enabled only for the CLI and SNMP models. |
|
Feature |
Description |
|---|---|
|
Additional YANG configuration models are included in this release to enable Unified SRST secure calling, applications for CUBE, and additional codecs for voice class codec lists. |
|
Feature |
Description |
|---|---|
|
Permanent License Reservation (PLR) in Smart Licensing Using Policy |
A PLR enables you to use an unlimited count of any license on the product instance. It is suited to a high-security deployment or entirely air-gapped networks where a product instance cannot communicate online, with anything outside its network. See: Permanent License Reservation in the Smart Licensing Using Policy Environment. |
