Temos vários switches e STP ativado em todos os switches.. Mas alguns dos switches estão piscando em quem se torna o mestre STP..
Acho que há alguns problemas de configuração.. Se olharmos para o interruptor "principal" e um dos outros..
O interruptor principal se parece com isso

O que posso ver é que ambos têm prioridade de raiz CST definida como 0? Mas tem prioridade de switch diferente ..
Eles também têm a mesma "Revisão de configuração do MST", mas um "Nome de configuração do MST" diferente.
Isso é correto?
