New Features

  • I95-26075 Generate PCAP directly from Session table: A button has been added to both the Session Debug table and the Top Sessions table that allows the user to create a PCAP file containing the specific row data from each table.

Resolved Issues

  • I95-41481 Reachability metrics actions are not available for TLS modify scenarios: Reachability stats for app-id session updates have been added.

  • I95-41617 In some rare cases the GUI may enter a re-render loop: Resolved an issue where the value provided by usePreLoginData was being used to determine if the application should re-render.

  • I95-41689 Limited search on FIB table: Restore FIB filtering query parameters.

  • I95-41704 Node processes using excessive CPU during upgrade: Changes made to initiate Swagger generation only when a file is updated or changed.

Caveats

  • I95-40335 Package dependency conflicts: 5.2.2 supports the vrsx-sfc plugin. With this plugin, upgrading to 5.3.0 is not supported. If the system is upgraded to 5.3.0 with this plugin installed, the plugin dependencies will be removed and the features provided with this plugin will no longer function.

Contains fixes from: Release 5.1.4, June 28, 2021

New Features and Improvements

  • I95-35414 Refresh actions now available for individual sections on the Router Page: The Device interface, Network Interface, and Peer Paths table sections now can be refreshed independently.

  • I95-36224 Handle names in application-id JSON: The application-module json output common-name object now includes a list of referenced common-names, in addition to the transport-information list.

  • I95-38244 The Routers Page is easier to Search: Added a column selector and a search matching system to make the search function more granular.

  • I95-38445 GUI Session Capture: Added pages to the user interface that allow you to view and configure capture information.

  • I95-40075/I95-40134 Use gateway from service route for interface ping gateway: The service-route next-hop gateway-ip will be used for ICMP ping reachability probe if so configured. If no IP is configured, then the fib-route gateway will be used, and finally the network-interface gateway will be used.

  • I95-40124 GRE Interface not inherting teneancy from parent: The GRE Interface now inherts teneancy and neighborhood configuration from parent.

  • I95-40168 show udp-transform not providing result details: The show udp-tranform reason field now provides correct details.

Release 5.2.0

Release Date: May 10, 2021

New Features and Improvements

  • I95-61 Service Health Learning and Fault Avoidance: In-path metrics and heuristics are now able to be used for server reachability and to determine network health. See Service Health Learning for more information.

  • I95-17681 Pre- and Post-Login Banners: Pre- and post-login banners can be configured by selecting Configuration, clicking on the Authority tile, and scrolling down to the Web Messages field.

  • I95-21631 Customized Tables: Support has been added for user customizable tables in the Custom Reports view of the GUI. Tables can have multiple metrics and display sum, average, min or max values across the selected time range.

  • I95-33451 Support Persistence for In-Memory Metrics: Metrics intended for persistence can be configured as part of a Metrics Profile. Profiles are configured at the Authority level and referenced by the relevant routers. Each Profile specifies a number of metrics and the desired parameter filters.

  • I95-36657 Improve Packet throughput of KNI-based Interfaces: KNI buffer performance has been enhanced to handle large bursts of traffic.

  • I95-37296 Native 128T Support for GRE: Native support (non-plugin) is availble for GRE Tunneling, providing better performance. For more information, see Native GRE Tunnels.

  • I95-37459 Show Commands for Services: The show fib and show fib lookup commands have been enhanced to provide more granular path-related debugging.

  • I95-37510 AppID Modules can be run as systemd units: Added support for module execution as a systemd unit in addition to the existing script-based method, and the use of REST APIs to propagate module registrations and results.

Resolved Issues

  • I95-38510 Security mismatch on HA nodes dropping internode traffic: Resolved an issue where dynamically reconfiguring inter-node-security may cause all internode traffic to be dropped.

  • I95-39477 Configuration validation failure when conductor non-forwarding fabric interfaces are configured in different subnets: Updated to display a warning to the user to correct the issue, rather than failing.

  • I95-39811 Office365 module not including TCP and UDP ports: Resolved an issue where the AppID module was not including port and protocol data.

  • I95-39817 General CPU Stats not showing in Conductor UI after upgrade: Resolved an issue where stats were not captured.

  • I95-39854 Management over Forwarding not bringing up Eth0 on shutdown: Resolved an issue preventing devices from unbinding cleanly.

  • I95-40208 Quickstart not setting the minion_id to the hardware identifier when the value is blank: Previously, if the Quickstart configuration did not have a value for the minion_id, the minion_id would not be set to the hardware identifier. This has been corrected in the 128T-5.2.0-1.el7.OTP.v2.x86_64.iso ISO.

Caveats

  • I95-26627 Prevent static route interface next hops with the same global ID: In HA configurations with a shared interface, only one node in the pair should be configured as a static route next hop. Othrewise, deleting the shared interface from one node will also cause the static route to be deleted.
