У нас возникла проблема с LLDP на последних прошивках для 3200-28 (сейчас это 1.70.B007). Выражается она в том, что 3200-28 перестаёт видеть окружение по LLDP, хотя сам LLDP отдаёт. Например, вот что я вижу на схеме из коммутатора DES-3526 (v.6.20.B09), подключенного 25 портом в DES-3200-28 (28 порт):

А если соединить два 3200-28 с такими прошивками, то они друг друга, соответственно, по LLDP видеть не будут :-\
