Release 2.0.14.0
2023-12-07
• New features:
○ Support for 2.5 Gb/s metallic SFP (2500 Base-T)
○ New Link State Propagation (LSP) functionality. LSP disables user data transmission when the
link speed drops below the preset threshold.
○ Remote unit management is now accessible also via Local unit management IP using port forward-
ing. It is useful in situations when internal switch configuration does not enable access to the Remote
unit IP (e.g. when two ETH ports are completely separated in order to serve different customers).
○ Faster ATPC reaction (better adaptation to sudden weather changes)
○ TX mute (possibility to suppress radio transmission)
○ Default WiFi channels are 5 and 9 (different for L and U unit)
• Fixed bugs:
○ Minor SW fixes and improvements (SNMP alarm)
○ Minor web interface fixes
• Known issues:
○ FW versions 2.x.x.0 are not over-the-air compatible with older FW versions 1.x.x.0 as a consequence
of the serial number system redesign. It is necessary to install the same major FW version in both
units forming a microwave link.
○ In the case of FW upgrade from versions 1.0.x.0 please read and apply instructions from section
Known issues for Release 1.1.1.0.

Release 2.0.11.0
2023-03-27
• New features:
○ Minor web interface improvements (new parameter ‘Max TX Power’, splitting ‘Current Tx Modulation’ and ‘Max Tx Modulation’ into 2 lines on the ‘Status’ page, etc.)
• Fixed bugs:
○ Eliminated non-functional button for storing differential unit configuration backup
○ Minor SW fixes and improvements (MSE trap, asymmetry, modulations in rare situations, details)
○ Minor web interface fixes
• Known issues:
○ FW versions 2.x.x.0 are not over-the-air compatible with older FW versions 1.x.x.0 as a consequence of the serial number system redesign. It is necessary to install the same major FW version in both units forming a microwave link.
○ After FW upgrade from versions 1.0.19.0 and earlier unit time has to be checked and manually corrected (may be wrong if time zones were used). 
○ After FW upgrade from versions 1.0.16.0 and earlier it is strongly recommended to set 'FlowControl receive' for port 'Air (p9)' to value 'on' ('Show Defaults' + 'Apply' in menu 'Switch settings / Interface / Port'). It improves an utilization of Ethernet switch buffers and allows higher throughput of the link for real traffic.

Occasional reboots may still happen in a very small percentage of links. In such a case please run the CLI command "cli_wdog_holdon -b" (in CLI or in box Command on the page Tools/Programs/CLI) on both sides of the link. This command prevents spontaneous reboots and starts to log internal system watchdogs (the reason for reboots). Then please contact Technical support on http://www.al-wireless.com/helpdesk-form-3.
