Le contrôleur Unifi de Ubiquiti sera bientôt disponible en version 4.7.6 qui intégrera quelques correctifs pour des problèmes.. dont certains non négligeables..

Changes from 4.7.5 to 4.7.6:

  • [CTLR] Upgraded Tomcat to 7.0.64 (current).
  • [CTLR] Fixed CVE-2011-1473 (requires Java 8) and default to 2048 bits strength ephemeral DH keys (requires jre7u85 or later) (reported HERE).
  • [UAP] Improved 2G stability on UAP-AC-Lite/UAP-AC-LR/UAP-AC-Pro.
  • [USW] Fixed DHCP guarding on Link Aggregation.
  • [USW] Fixed a bug that switch cannot boot after upgrading to 3.3.10 (reported HERE).
  • [USW] Fixed a bug that 802.3af/at auto sensing PoE is not working on port 25-48 on US48P-500/US48P-750 when the system is cold rebooted (reported HERE).



Cela corrige notamment un problème avec les switches US48P-500/US48P-750 qui perdent la gestion “correcte” du PoE sur les ports 25 à 48 en cas de reboot… Un bug légèrement gênant :D

Ce cas est discuté et reporté ici sur le forum UBNT.
