Version 2.8.36

Supported hardware

Hardware ModelCisco IXMStandalone/1-box version (Corsica)
Firmware Version2.3.1HAL 5.1
LRR version2.8.36Standard 2.8.36

New features

  • New firmware support: This version introduces the support of Cisco firmware 2.3.1.

  • Support TLS as a new communication security protocol: TLS (Transport Layer Security) has been added along with IPSec (Internet Protocol Security). By default, TLS is used to encrypt every message going from the LRR to the ThingPark platform. IPSec can still be used and configured using the Suplog. To learn more, see Activating a secure connection via IPSec or TLS.

  • Allow configuring ICMP destinations in SUPLOG (RDTP-17415): Make it possible to customize the ICMP destinations in SUPLOG to comply with specific deployment use cases where ICMP protocol is not authorized on ThingPark's server side.

  • Introduction of embedded virtual device probe: This feature provides insight into the RF quality of the network using an emulated device in the LRR to send messages over the LRR antenna, and then analyze the quality of the received uplink packet by other surrounding LRRs.

  • Introduction of new managers: Centralmgr is now centralizing all information from the other managers: gwmgr, failovermgr, restoremgr, rollbackmgr, lrrmgr, pkimgr.
