Recentemente abbiamo installato il wireless 802.1x nella nostra sede di Londra. Un utente sta segnalando che una copia ssh tra la sottorete wireless e la nostra sottorete del server provoca trasferimenti costantemente rallentati e infine bloccati. Lo stesso trasferimento su due segmenti cablati (utilizzando lo stesso gateway - un ASA) è rapido.
Di seguito è la configurazione dall'unità. Ho già visto questo problema in ambienti Cisco, ma non ho mai fatto parte del team incaricato di risolvere il problema prima, quindi non ho idea di cosa potrebbe causarlo.
Qualcuno può condividere alcune idee su come risolvere questo problema?
