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.

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.

Table 2. Software Features

Feature

Description

Support for ConnectX-5VF vNIC

Cisco Catalyst 8000V now supports the ConnectX-5VF Virtual Network Interface (vNIC) card for deployments in ESXi, KVM, and NFVIS (CSP) environments. This enhancement provides multiple benefits including advanced hardware offloads to reduce CPU resource consumption and enhanced drive for high packet rates and throughput.

See also Requirements for KVM Installation and Installing Cisco Catalyst 8000V in NFVIS Environment.

Support for c5n.18xlarge instance type

Cisco Catalyst 8000V running on Amazon Web Services (AWS) now supports the c5n.18xlarge instance type for deployment. This instance type supports Elastic Fibre Adapter (EFA) that enhances performance especially in network intense solutions.

AWS Enhancements

Cisco Catalyst 8000V running on AWS supports performance enhancements with higher number of queues, thereby increasing the packet processing rate.

Support for Unicast-to-Multicast Destination Reflection

This feature introduces support for configuration of unicast-to-multicast destination reflection to facilitate unicast-to-multicast destination translation and unicast-to-multicast destination splitting. It also provides the capability for users to translate externally received unicast destination addresses to multicast addresses.

Support for BGP additional paths with label-unicast unique mode

This enhancement introduces support for configuring BGP additional paths when label-unicast unique mode is configured.

ACE Scale Limit Per OGACL

This feature provides the capabilities to increase the Common Adaptive Classification Engine (CACE) scale limit per ACL and object group (OG) ACL. Currently, the CACE supports only 64K ACEs per ACL and it can have 64K networks in the source and destination OGs per policy.With the increase in CACE limit to 256K, Cisco Catalyst 8000v Edge Software can now support 150K ACE entries per ACL with 270K ACEs per system across five ACLs. Additionally, the device can support 3000 ACE entries per OGACL and 2400 OGs with 100 networks per OG.Cisco Catalyst 8000v must have 8 GB memory to support this configuration.

Table 3. Cisco Unified Border Element (CUBE) Features

Feature

Description

CUBE: End-to-end Secure Calling for Courtesy Call Back and Unified Contact Center Survivability

With the Cisco Voice Portal (CVP) application, a caller may request an automatedcallback, rather than wait in a queue for an extended period. When an agent becomes available, CVP sends a request to place a call to the original caller. When the call is answered, the agent is connected. With this update, outbound calls over a secure SIP PSTN trunk are possible.

CUBE: Load Balancing for DNS SRV Host

This enhancement to the DNS session target feature, provides effective call distribution and load balancing of calls based on the preference, priority and availability of hosts provided in DNS SRV Resource Records. This feature further simplifies configuration by allowing effective call distribution with a single dial-peer.

CUBE: Options Ping for DNS SRV Hosts

Previously, CUBE (Local Gateway) had to be configured with separate dial-peers to monitor the availability of individual proxies used in services such as Webex Calling. To simplify this configuration, all targets resolved from a DNS SRV record may now be monitored using a common Options Ping policy defined for a single dial-peer. If a remote server becomes unresponsive, CUBE will busy out that destination, allowing calls to be sent to alternative destinations.

Transfer of Call Detail Records Using SFTP

Cisco IOS gateways can use FTP and now SFTP servers to transfer call accounting files.


Note


Customers using the CUBE WebSocket forking feature with the Cisco Agent Answers solution should not use the Cisco IOS XE Cupertino 17.9.1a release. We recommend that you use the Cisco IOS XE Bengaluru 17.6.x release for this feature.


Table 4. Smart Licensing Using Policy Features

Feature

Description

Managed Service License Agreement (MSLA) Support with Smart Licensing Using Policy.

For Cisco Catalyst 8000V running in the autonomous mode, you can now implement a post-paid model for licenses, where you pay for the actual usage of a license instead of pre-paying for the licenses you may require.

This model requires an MSLA with Cisco, and licenses with subscription ID. (Licenses with subscription IDs to be ordered on Cisco commerce workspace (CCW). The licenses are deposited in the specified Smart Account and Virtual Account in CSSM, with the corresponding subscription IDs.

To complete licensing workflows, you can implement a topology where the product instance interacts directly with Cisco Smart Software Manager (CSSM), via Cisco Smart Licensing Utility (CSLU), or via Smart Software Manager On-Prem (SSM On-Prem), or it can operate in a disconnected mode. A product instance that uses licenses with subscription IDs must also enabled with a "utility mode”. Communication to and from the product instance is flagged to indicate that it is in the utility mode.

A product instance in the utility mode requires a Resource Utilization Measurement Acknowledgement (RUM ACK) installed every 30 days. You are billed based on the throughput and the Cisco DNA subscription tier that is activated and in-use.

New mechanism to send data privacy related information

A new mechanism to send data privacy related information was introduced. This information is no longer included in a RUM report.

If data privacy is disabled (no license smart privacy {all | hostname | version} command in global configuration mode), data privacy related information is sent in a separate sync message or offline file.

Depending on the topology you have implemented, the product instance initiates the sending of this information in a separate message, or CSLU and SSM On-Prem initiates the retrieval of this information from the product instance, or this information is saved in an offline file.

For more information, see license smart (global config).

Hostname support

Support for sending hostname information was introduced.

If you configure a hostname on the product instance and disable the corresponding privacy setting (no license smart privacy hostname command in global configuration mode), hostname information is sent from the product instance, in a separate sync message or offline file.

Depending on the topology you have implemented, the hostname information is received by CSSM, CSLU, and SSM On-Prem. It is then displayed on the corresponding user interface.

For more information, see license smart (global config).

With the introduction of this enhancement, the hostname limitation which existed from Cisco IOS XE Amsterdam 17.3.2 to Cisco IOS XE Cupertino 17.8.x – is removed. In these earlier releases, hostname information is not sent or displayed on various licensing utilities (CSSM, CSLU, and SSM On-Prem).

RUM Report Throttling

For all topologies where the product instance initiates communication, the minimum reporting frequency is throttled to one day. This means the product instance does not send more than one RUM report a day.

The affected topologies are: Connected Directly to CSSM, Connected to CSSM Through CSLU (product instance-initiated communication), CSLU Disconnected from CSSM (product instance-initiated communication), and SSM On-Prem Deployment (product instance-initiated communication).

This resolves the problem of too many RUM reports being generated and sent for certain licenses. It also resolves the memory-related issues and system slow-down that was caused by an excessive generation of RUM reports.

You can override the reporting frequency throttling, by entering the license smart sync command in privileged EXEC mode. This triggers an on-demand synchronization with CSSM or CSLU, or SSM On-Prem, to send and receive any pending data.

RUM report throttling also applies to the Cisco IOS XE Amsterdam 17.3.6 and later releases of the 17.3.x train, and Cisco IOS XE Bengaluru 17.6.4 and later releases of the 17.6.x train. From Cisco IOS XE Cupertino 17.9.1, RUM report throttling is applicable to all subsequent releases.

Virtual Routing and Forwarding (VRF) Support

On a product instance where VRF is supported, you can configure the license smart vrf vrf_string command and use a VRF to send licensing data to CSSM, or CSLU, or SSM On-Prem.

Note

 

When using a VRF, the supported transport types are smart and cslu only.

For more information, see license smart (global config).
