Ho un AP 1260 che ho aggiornato questa mattina. Prima dell'aggiornamento, il sistema consentiva ssh e rispondeva ai ping sulla rete, tuttavia ora non risponde.
Ho collegato un cavo seriale e navigando nella configurazione non riesco a trovare nulla di sbagliato, e l'attivazione del debug ssh non produce alcun output.
Ho provato a rigenerare la chiave RSA nel caso in cui ciò causasse la mancata connessione di ssh online, tuttavia non ha influito sull'impossibilità di contattare l'unità sulla rete.
Ho anche provato ad attivare "ip routing" e "ip cef" pensando che potrebbero essere il problema, ma nessun effetto. Ho anche aggiunto una route predefinita statica al nostro gateway di gestione nella speranza che forse fosse un problema di route predefinita ma che non ha aiutato
Ecco la versione corrente di IOS sull'unità:

Qualsiasi suggerimento sarebbe apprezzato, sono piuttosto sconcertato sul perché questo improvvisamente andrebbe storto.
EDIT : Ecco la ricostruzione dell'output delle chiavi crittografiche.
