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.

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.

Cisco IOS XE Cupertino 17.7.1a is the first release for Cisco Catalyst 8000V in the Cisco IOS XE Cupertino 17.7.x release series.

Table 2. Software Features

Feature

Description

Factory-installed Trust Code

For new hardware and software orders, a trust code is now installed at the time of manufacturing.

Note

 

You cannot use a factory-installed trust code to communicate with CSSM.

Installing Cisco Catalyst 8000V in an OpenStack Environment

Starting with the Cisco IOS XE Release 17.7.1a, you can now install Cisco Catalyst 8000V on OpenStack software (Train release) which acts as a hypervisor manager. The OpenStack Train release is the 20th version of the open-source cloud infrastructure software on which you can launch Cisco Catalyst 8000V virtual machines (VMs) or instances.

Flexible NetFlow Support on BD-VIF

This feature introduces Flexible NetFlow (FNF) support on Bridge Domain Virtual IP Interfaces (BD-VIF). Flexible Netflow provides improved optimization and performance, enhanced security, and increased flexibility and scalability to the network. You can configure FNF on a BD-VIF using the ip flow monitor command.

Marking Packets Sent Via ATM Interface With COS(BITP) Value

This feature introduces the ‘set cos 3’ command using which you can configure the router to mark the packets with a cos (bitp) value. The marked packets are indicators of priority for the user, and based on the priority level, the bandwidth is allocated.

Multicast - mcast group calculation

The show ip multicast overlay-mapping command displays an underlay group address from the overlay group address which is used to troubleshoot or configure the network. The output includes the underlay group address that is within the configured SSM (Source Specific Multicast) address range.

CUBE Features

Secure Web Socket-based Media Forking on Cisco 4431, 4451-X, and 4461 Integrated Services Routers

From Cisco IOS XE Cupertino 17.7.1a, CUBE can use WebSockets to handle media forking with Cloud Speech Services on the Cisco 4431, 4451-X, and 4461 Integrated Services Routers platforms apart from the existing support on Cisco Catalyst 8000V Edge platform.

YANG Configuration Models for CUBE

From Cisco IOS XE Cupertino 17.7.1a, YANG models are now available to configure and manage CUBE.

Programmability Features

Converting IOS Commands to XML

 This feature helps to automatically translate IOS commands into relevant NETCONF-XML or RESTCONF/JSON request messages.

ZTP Configuration through YANG

ZTP is enabled through YANG models when NETCONF is enabled.

Smart Licensing Using Policy Features

Ability to save authorization code request and return in a file and simpler upload in the CSSM Web UI

If your product instance is in an air-gapped network, you can now save a SLAC request in a file on the product instance. The SLAC request file must be uploaded to the CSSM Web UI. You can then download the file containing the SLAC code and install it on the product instance. You can also upload a return request file in a similar manner.

With this new method you do not have to gather and enter the required details on the CSSM Web UI to generate a SLAC. You also do not have to locate the product instance in the CSSM Web UI to return an authorization code.

In the CSSM Web UI, you must upload the SLAC request or return file in the same way as you upload a RUM report. In the required Smart Account, navigate to Reports → Usage Data Files.

See: No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU, Saving a SLAC Request on the Product Instance, Removing and Returning an Authorization Code, Uploading Data or Requests to CSSM and Downloading a File

Account information included in the ACK and show command outputs

A RUM acknowledgement (ACK) includes the Smart Account and Virtual Account that was reported to, in CSSM. You can then display account information using various show commands. The account information that is displayed is always as per the latest available ACK on the product instance. See: show license summary, show license status, show license tech.

CSLU support for Linux

CSLU can now be deployed on a machine (laptop or desktop) running Linux.

See: CSLU, Workflow for Topology: Connected to CSSM Through CSLU, Workflow for Topology: CSLU Disconnected from CSSM

Factory-installed trust code

For new hardware and software orders, a trust code is now installed at the time of manufacturing.

Note

 

You cannot use a factory-installed trust code to communicate with CSSM.

See: Overview, Trust Code

RUM Report optimization and availability of statistics

RUM report generation and related processes have been optimized. This includes a reduction in the time it takes to process RUM reports, better memory and disk space utilization, and visibility into the RUM reports on the product instance (how many there are, the processing state each one is in, if there are errors in any of them, and so on).

See: RUM Report and Report Acknowledgement, Upgrades, Downgrades, show license rum, show license all, show license tech.

Support for trust code in additional topologies

A trust code is automatically obtained in topologies where the product instance initiates the sending of data to Cisco Smart License Utility (CSLU) and in topologies where the product instance is in an air-gapped network.

See:

Trust Code

Connected to CSSM Through CSLU, Tasks for Product Instance-Initiated Communication

CSLU Disconnected from CSSM, Tasks for Product Instance-Initiated Communication

No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU

Support to collect software version in a RUM report

If version privacy is disabled (no license smart privacy version global configuration ) command, the Cisco IOS-XE software version running on the product instance and the Smart Agent version information is included in the RUM report.

See: license smart (global config)

Tier- Based Licenses

You can now configure tier-based throughput values if the license PID is tier-based. For example, for PID DNA-C-T0-E-3Y, you can configure Tier 0 (T0) as the throughput value on the platform.

Each tier represents a throughput level. Starting with the lowest throughput level, the available tiers on the Cisco Catalyst 8000V Edge Software are: T0, Tier 1 (T1), Tier 2 (T2), and Tier 3 (T3).

If you purchase a tier-based license PID, the license is displayed with the tier value in the CSSM Web UI. You can also convert the numeric throughput configuration of any existing tier-based license PIDs to a tier-based throughput value.

Note

 

T2 and higher tiers require an HSECK9 license and Smart Licensing Authorization Code (SLAC).

Different platforms support different maximum throughput levels, therefore each tier means a different value for different platforms.

The configuration guide provides details about how numeric throughput values map with tiers and how you can change to tier-based configuration. See Available Licenses and Licensing Models.
