SSH Root Login is not permitted.
Before upgrading, ensure that there is at least one user on each 128T system that has sudo privileges. Failure to do so may result in the loss of remote management connectivity to the 128T Networking Platform. Please see the Installation Overview for additional information.
New Features and Improvements
- I95-9152 PCLI configuration help text identifies required fields: When using the PCLI configuration command, the required fields are now identified within the Help text.
- I95-9242 Service and Topology Exchange Protocol (STEP): STEP facilitates the design and scale of new (and exisiting) networks by network administrators, and provides insight into service availablity across the network. STEP is designed for service exchange and reachability to those services used by routers to efficiently route packets for each service.
- I95-15618 Auto completion: Auto completion is now available on the
clear arpPCLI command.
- I95-20757 Displaying alarm history: Displaying the Alarm History within the PCLI using
show events alarmnow supports relative timestamps.
- I95-22350 Hierarchical Services allow you to create groupings of services that inherit properties from one another.
- I95-25513 Display 128T, Installer, and Installer Repo Versions: The GUI and CLI both display the software version, installer version, and installer repo versions.
- I95-27886 Packet Duplication for Inter-Node High Availability: Packet duplication over multiple inter-node links helps reduce packet loss during transmission. For protocols such as UDP that do not verify packet integrity, this helps ensure full transmission of traffic. See service-policy for usage information.
- I95-28531 Application Categorization: Application Identification/Categorization utilizes a database of traffic categories, such as “News”, “Social Media”, “Health”, “Sports”, etc. These categories can be assigned to services, which can then be prioritized, monitored for traffic levels, or blocked for security purposes. Each category is populated with a list of domain names associated with the type of traffic.
- I95-31218 Configurable BFD Hold-Down Timer: BFD (Bidirectional Forwarding Detection) is used to detect path failures between routers. A configurable hold-down time and dynamic-damping field in the BFD settings, shared at the router, peer, interface neighborhood, and adjacency levels, provides BFD damping functionality when links are unpredictable.
- I95-32558 In-line Flow Performance Monitoring: Inline performance metrics have been enhanced to achieve a finer granularity than what is currently available via BFD. Statistics are now collected per path, traffic class, and protocol (TCP or UDP) level. Sessions can be forwarded using more granular SLA metrics.
- I95-33376 Address Latest Vulnerabilities: Security Vulnerability testing is ongoing, and fixes are in place for identified issues.
- I95-33395 Improved PCLI startup time by 60%: The PCLI start up process has been streamlined to be quicker and more efficient.
- I95-34217 GraphiQL API explorer and request builder within GUI: The GraphiQLExplorer is an extension to the existing GraphiQL interactive API viewer in the 128T GUI. The addition of the GraphiQLExplorer makes it even easier to write 128T configuration queries and explore schema types. A new sidebar labeled “Explorer” contains a list of the top-level queries used throughout the GUI. Click on each one to expand their nested properties, which reflect the GraphQL schema structure.
- I95-34788 Support for bulk configuration edits via REST: The 128T REST API can be used to add a new configuration consisting of multiple objects, or to modify or patch multiple levels of configuration, with a single REST request.
- I95-34823 About page includes link to online documentation: The 128T GUI now includes a link to the online documentation set.
- I95-35150 PCLI Clone Configuration: The clone command duplicates the configuration data from an existing router into a new router with a new name, and stages it to the candidate configuration.
- I95-35190 PCLI bulk paste configuration: The PCLI detects configuration entered in bulk and accepts input in either show config native format or flat format.
- I95-35212 Adaptive Encryption: Most end hosts employ secure protocols such as TLS and IPSEC. Adaptive Encryption is aimed at identifying this already encrypted traffic and providing security for non-encrypted traffic by encrypting it through the 128T Router. This eliminates the performance penalty of encrypting traffic that is already encrypted.
- I95-35741 PCLI plugin service commands: The plugin lifecycle can now be managed through the PCLI.
show assests softwareincludes Repository information: The PCLI command
show assets softwareincludes the repository for each available software version.
- I95-38170 Updated path metrics for
show service-path: Latency, loss, and jitter metrics are displayed when they are available, even if performance monitor is not enabled for the path.
- I95-20718: Keywords as Configuration Values - the PCLI now prevents the use of keywords as configuration values.
- I95-29643 Changing the name of an existing configuration object to one that already exists merges the two objects.
- I95-30670 Version mismatch alarm in HA pair is not generated when the salt minion is disconnected on one of the nodes in the pair.
- I95-32016 Output from
show config out-of-syncdisplays
49 yearsfor disconnected routers.
- I95-34065 Leading and trailing whitespace is now correctly trimmed from configuration input fields.
- I95-34078 Conductor asset status is empty.
- I95-34448 Viewing "Event History" in GUI can result in an error dialog with the following content:Error: TypeError: expected dynamic type `int/double/bool/string', but had type `null'at t.f [as project] (https://22.214.171.124/21.chunk.4855571a0034f587fb2f.js:1:28085)at t._next (https://126.96.36.199/main.98467ce8a2ab8ddd6c0c.js:29:145514)at t.next (https://188.8.131.52/main.98467ce8a2ab8ddd6c0c.js:16:68940)at https://184.108.40.206/main.98467ce8a2ab8ddd6c0c.js:41:211792

I95-35521 pcli may provide a validation error but does not provide the specific configuration in error.
Corrective Action: If a validation error is provided, review the configuration of each sub list between the items identified in the error response provided. For example, the same vlan id cannot be used for different networks interfaces on the same device interface.
