Cisco Tetration Release Notes
Release 3.3.2.28
This document describes the features, caveats, and limitations for the Cisco Tetration software, release 3.3.2.28.
The Cisco Tetration platform is designed to comprehensively address a number of data center operational and security challenges using rich traffic telemetry collected from servers, layer 4 through 7 service elements, and end-point devices (such as laptops, desktops, and smartphones). The platform performs advanced analytics using an algorithmic approach to offer a holistic workload protection platform. This algorithmic approach includes unsupervised machine-learning techniques and behavioral analysis. The platform provides a ready-to-use solution supporting the following use cases:
■ Provide behavior-based application insight to automate allowed-list policy generation
■ Provide application segmentation to enable efficient and secure zero-trust implementation
■ Provide consistent policy enforcement across on-premises data centers, and private and public clouds
■ Identify process behavior deviations, and software vulnerabilities and exposure to reduce attack surface
■ Identify application behavior changes and policy compliance deviations in near-real time
■ Support comprehensive telemetry processing in a heterogeneous environment to provide actionable insight
within minutes
■ Enable long-term data retention for deep forensics, analysis, and troubleshooting
To support the analysis and various use cases within the Cisco Tetration platform, consistent telemetry is required from across the data center infrastructure. Rich Cisco Tetration telemetry is collected using agents. There are different types of agents available to support both existing and new data center infrastructures. This release supports the following agent types:
■ Software agents installed on virtual machine, bare-metal, or container hosts
■ ERSPAN agents that can generate Cisco Tetration telemetry from copied packets
■ Telemetry ingest from ADCs (Application Delivery Controllers) – F5, Citrix and AVI
■ NetFlow agents that can generate Cisco Tetration telemetry based on NetFlow v9 or IPFIX records
■ Embedded hardware agents in Cisco Nexus 9000 CloudScale series switches
In addition, support ingesting endpoint device posture, context and telemetry through integrations with
■ Cisco AnyConnect installed on endpoint devices such as laptops, desktops, and smartphones
■ Cisco ISE (Identity Services Engine)
Software agents also act as the policy enforcement point for the application segmentation. Using this approach, the Cisco Tetration platform enables consistent microsegmentation across public, private, and on-premises deployments. Agents enforce the policy using native operating system capabilities, thereby eliminating the need for the agent to be in the data path and providing a fail-safe option. Additional product documentation is listed in the “Related Documentation” section.

No new software features in this release.
Changes in Behavior
These are changes in behavior for this release:
■ Before shutdown/reboot of the cluster, you should ensure hardware health is good via Cluster Upgrade Pre-checks.
■ IP packets might be fragmented into multiple packets. In case of TCP/UDP, the source and destination ports are only carried in the first fragment. The subsequent ones are therefore wrongly classified as a flow with port 0 (both source and destination) by Tetration agents. After this release, all the subsequent fragments other than the first will be dropped by the agents. Hence TCP/UDP flows with port 0 will not be observed anymore. The statistics for each flow (total bytes and packets) might not be accurately accounted for those fragments.
■ In Software Agents List view, when an agent has a larger number of interfaces, we now show up to five IP addresses to avoid a lengthy interface listing that fills up the entire page. You can view all interfaces by clicking “more…” to extend the interface list as an embedded table display.
This section contains lists of open and resolved caveats, as well as known behaviors.

Description |
Port setting in syslog connector not applying to Edge Appliance

|
ADM External Dependencies not saving from previous run |
|
Infoblox integration causes /local directory to fill up |
|
Fragmented UDP packets are marked as UDP 0 |
■ During upgrade when a new RPM is uploaded, adhocKafka is gracefully shut down. This is done to avoid Kafka index corruption. Kafka comes back up after the upgrade. If upgrade is aborted after uploading the RPM, adhocKafka should be restarted using the explore command.
