View dropped packets

I'm new to ASAs and would like to know the following:

1. What's the easiest way to view denied packets that are being dropped due to firewall ACLs? Is there a command line and GUI version. I'm using an ASA with IOS 8.3


RE: View dropped packets

You need to enable logging and watch either the log buffer or, having enabled remote (syslog) facility, the log server.
To enable logging, just an example:

logging enable
logging timestamp
logging buffer-size 500000
logging monitor critical
logging buffered errors
To add syslog to the above:

logging trap informational

RE: View dropped packets

cool, thanks
