Configuration Examples for the Botnet Traffic Filter
hostname(config-pmap-c)#
inspect dns preset_dns_map dynamic-filter-snoop
hostname(config-pmap-c)#
service-policy dynamic-filter_snoop_policy interface outside
hostname(config)#
dynamic-filter enable interface outside
hostname(config)#
dynamic-filter drop blacklist interface outside
The following recommended example configuration for multiple context mode enables the Botnet

match port udp eq domain
hostname/context2(config-cmap)#
policy-map dynamic-filter_snoop_policy
hostname/context2(config-pmap)#
class dynamic-filter_snoop_class
hostname/context2(config-pmap-c)#
inspect dns preset_dns_map dynamic-filter-snoop

service-policy dynamic-filter_snoop_policy interface
outside
hostname/context2(config)#
dynamic-filter enable interface outside
hostname/context2(config)#
dynamic-filter drop blacklist interface outside
Other Configuration Examples
The following sample configuration adds static entries are to the blacklist and to the whitelist. Then, it
monitors all port 80 traffic on the outside interface, and drops blacklisted traffic. It also treats greylist
addresses as blacklisted addresses.
hostname(config)#
dynamic-filter updater-client enable
hostname(config)#
