+=head1 NAME
+
+App::Netdisco::SSHCollector::Platform::FTD
+
+=head1 DESCRIPTION
+
+Collect IPv4 ARP and IPv6 neighbor entries from Cisco Firepower devices.
+
+You will need the following configuration for the user to automatically enter
+C<enable> status after login:
+
+ aaa authorization exec LOCAL auto-enable
+
+To use an C<enable> password separate from the login password, add an
+C<enable_password> under C<device_auth> tag in your configuration file:
+
+ device_auth:
+   - tag: sshftd
+     driver: cli
+     platform: FTD
+     only: '192.0.2.1'
+     username: oliver
+     password: letmein
+     enable_password: myenablepass

+=item B<arpnip($host, $ssh)>
+
+Retrieve ARP and neighbor entries from device. C<$host> is the hostname or IP
+address of the device. C<$ssh> is a Net::OpenSSH connection to the device.
+
+Returns a list of hashrefs in the format C<{ mac =E<gt> MACADDR, ip =E<gt> IPADDR }>.
