What's new in Digi EX12 version 22.8
Release of Digi EX12 firmware version 22.8:
nCellular modem enhancements:
lAdded modem ota download and system firmware ota download commands for
downloading cellular modem and device firmware.
lAdded cellular carrier name and PLMN ID to the Modems Status page in the Web UI.
lEnhanced access technology options to set the modem to 5G-only, including setting to 5G
SA-only, NSA-only, or both NSA/SA-modes.

CHAPv2) as an option for L2TP network servers authentication methods.
nContainer support:

datapoints to DigiRM.
nAdded support for running a PPPoE server when an interface is in IP passthrough mode.
nAdded ability to specify DFS channels for Wi-Fi client background scanning when DFS client
support is enabled.
nAdded a show eth Admin CLI command to show the link status of each Ethernet port.
