show dynamic-filter reports infected-hosts
{max-connections | latest-active |
highest-threat
| subnet ip_address netmask
| all}
Generates reports about infected hosts. These reports contain detailed
history about infected hosts, showing the correlation between infected
hosts, visited malware sites, and malware ports. The max-connections
keyword shows the 20 infected hosts with the most number of
connections. The latest-active keyword shows the 20 hosts with the most
recent activity. The highest-threat keyword shows the 20 hosts that
connected to the malware sites with the highest threat level. The subnet
keyword shows up to 20 hosts within the specified subnet. The all
keyword shows all buffered infected-hosts information. This display
might include thousands of entries. You might want to use ASDM to
generate a PDF file instead of using the CLI.
To clear the report data, enter the clear dynamic-filter reports
infected-hosts command.
show dynamic-filter updater-client
Shows information about the updater server, including the server IP
address, the next time the ASA will connect with the server, and the
database version last installed.
show dynamic-filter dns-snoop
[detail]
Shows the Botnet Traffic Filter DNS snooping summary, or with the
detail keyword, the actual IP addresses and names. All inspected DNS
data is included in this output, and not just matching names in the

To clear the DNS snooping data, enter the clear dynamic-filter
dns-snoop command.
show dynamic-filter data
Shows information about the dynamic database, including when the
dynamic database was last downloaded, the version of the database, how
many entries the database contains, and 10 sample entries.
