Please Help!

подскажите, есть два коммутатора dgs3420

оба друг в друга смотрят, 18,22 и 28 портом
ниже show stp ports 18,22,28 каждого

Правильно ли я понимаю, что STP вообще не отрабатывает????

первый:

может я что позабыл,

root - первый.
а вот лог "втогого". Это же не нормально?

--------а это вообще саботаж какой-то. и 18-й и 28-й в Forwarding?????

Сделайте на каждом и проверьте одинаковый ли настройки
show config modified include "stp"

еще есть полезная команда
show stp instance

1.
config stp fbpdu enable
config stp priority 4096 instance_id 0
config stp ports 1-16,18,22 externalCost auto edge false p2p auto state enable restricted_role false restricted_tcn false
config stp ports 1-28 fbpdu enable
config stp ports 21,23-27 externalCost auto edge false p2p auto state disable restricted_role false restricted_tcn false
config stp ports 28 externalCost 1 edge false p2p auto state enable restricted_role false restricted_tcn false
enable stp
disable stp multiprocess_rstp

2.
Command: show config modified include "stp"
config stp fbpdu enable
config stp priority 0 instance_id 0
config stp ports 1-16,18,22,28 externalCost auto edge false p2p auto state enable restricted_role false restricted_tcn false
config stp ports 1-28 fbpdu enable
config stp ports 21,23-27 externalCost auto edge false p2p auto state disable restricted_role false restricted_tcn false
