Cisco Tetration Release Notes
Release 3.4.1.14
Warning: Cisco Tetration 3.4.1.14, which was briefly available on Cisco.com, is deferred due to a critical software issue. For more information, see CSCvw05529 in the Cisco Bug Search Tool.
This document describes the features, caveats, and limitations for the Cisco Tetration software, release 3.4.1.14.
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 allow-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 ingestion from ADCs (Application Delivery Controllers) – F5 and Citrix
■ 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 is provided for 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 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.
These Release Notes are sometimes updated with new information about restrictions and caveats. See the following website for the most recent version of this document:

This document includes the following sections:
■ Caveats
This section lists the new and changed features in this release and includes the following topics:
■ Software agent support added for CentOS 8.2 and Oracle Linux 8.2 to support all workload protection capabilities.
■ In workload profile summary page where Tetration software agent is installed, user with right privileges will be able to download agent logs. This feature is available for all deep Visibility and enforcement Agents.
No changes in behavior.
■ Some of the UCS M4 based Tetration 39RU clusters may contain Solid State Drives (SSDs) in the TA-SNODE-G1 nodes that are impacted by the field notice - https://www.cisco.com/c/en/us/support/docs/field-notices/705/fn70545.html. In this patch, there is an explore endpoint (fieldnotice_7545) that will report and remediate this issue.
— Please use a POST to orchestrator.service.consul with a snapshot path of fieldnotice_7545?usage=true to get details on how to use this endpoint. The endpoint runs in the background and will return a report in 2 to 3 minutes that indicates which drives are potentially impacted and how many hours they have been in operation.
— To view the details of the report please POST to orchestrator.service.consul with a snapshot path of:
cat?args=/local/logs/tetration/snapshot/cmdlogs/snapshot_fieldnotice_7545_log.txt. The cat endpoint may not return any data until the command completes.
— When the explore endpoint is run as fieldnotice_7545?args=-fix the endpoint will apply the SSD firmware upgrade to remediate the issue, the entire process usually takes approximately 15 minutes to complete. Drives are updated one at a time so there should be minimal to no impact to services. Since this process runs in the background it requires the cat command to view the output.
■ External Orchestrator F5 integration now supports reading health check configuration from F5 appliances. These health checks for the pool of members are referred to as Monitors in F5 terminology. The additional configuration is used by the enforcement engine to automatically permit health check traffic to backend members, making intents previously added for this purpose redundant.
■ With this release, inventory annotation via DNS orchestrator has been enhanced to now annotate any matching inventory (learned or static), even if the IP is not explicitly learned through agent or inventory upload. This information will be displayed as a single multi-value annotation called “orchestrator_system/dns_name”, whose value will be the DNS entries that point (directly or indirectly) to that IP address.
■ Enhancements to Admiral alerts:
— Detect and alert on disk failure, DIMM (Memory) failure and Fan speed issues.
— Disk usage warning and critical alerts enhanced to monitor /root, /tmp and /var/log.

|
UCS firmware update does not upgrade disk firmware |
|
AnyConnect Connector does not support AnyConnect 4.9 IPFIX templates. |
■ 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.
■ In custom dashboards feature, after upgrade to this version, all the site admin users should update their views based on Tetration data sources with the corresponding tenant-based Tetration data sources.
■ The Tetration enforcement (EFE) traffic on port 5660 is not filtered out and will be shown in policy analysis. If there are no corresponding policies to allow this traffic, the flows will show up as ESCAPED in policy analysis and enforcement analysis and may trigger alerts. A workaround is to create manual ALLOW policies to cover this traffic.
