Show command not working on ASA5520

Unanswered Question
Feb 3rd, 2010

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.

Anyone seen this before?

I have this problem too.

I have not seen this on the ASA but i have seen something similar on the Cisco ACE, which was due to excessive resource usage, due to code bug.

The only resolve was a reboot until we upgraded.

Is this happening on both active and standby firewalls?

Usually this happened for the show commands that had an excessive amount of output.

Try the show cpu usage and show memory cmds which have minimal output, they might shed some light, if they work.

Also have a quick check through the release notes for your code version, just in case.

Hi.

cpu usage on this ASA could be related.

Maybe cmmand authorization enabled and ACS connectivity isssues?

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.

Thanks for the input.
