We have two ASA5520's in a active/standby configuration. We have been unable to use any of the show commands. Everything else seems to work ok but if we want to look at the running-config/startup/interfaces etc, anything that uses show, it just sits there and eventually times out.
It is happening on both the active and standby firewalls. We think we have found the issue. It seems to be SSH v2 is causing the problem as we have been able to connect to a directly connected switch and then TELNET from the switch to firewall. All the show commands now work. It may mean we have to blast the config back onto the firewalls.
