LCOS SX 5.30 RU2 features
For switches of the CS and YS series
Various bug fixes and product improvements
LCOS SX 5.20 RU12 bugfixing
For switches of the XS-6000, XS-5000, and XS/GS-4500 series
- The stability of LMC communication has been improved. After a restart or crash of the SNMP interface, invalid parameters are no longer transmitted to the LMC, ensuring that rollouts can still be performed.
- The processing of static routing entries during LMC rollouts has been optimized. This prevents high CPU utilization, process terminations, and the loss of routing entries.
- Fixed an issue that caused LMC rollouts to fail when DNS server addresses contained a "9" (IPv4) or an "f" (IPv6) in the last octet.
- Compatibility of LANCOM SFP-DAC40-1M/-3M cables with GS-/XS-45xx switches and Unified Firewalls equipped with the UF Extension Module 2x40G QSFP+ has been improved.
- Distribution of PoE schedule profiles within GS-45xx stacks has been corrected. The PoE scheduler now functions as intended on stack members as well.
- CPU utilization on the XS-4530YUP and XS-4554YUP has been reduced by improving the efficiency of link LED control.

Before upgrading your device to a new firmware it is essential to backup your device’s configuration.
