| =head1 DESCRIPTION
 | |
| 
 | |
| Collect IPv4 ARP and IPv6 neighbor entries from Cisco ASA 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 seaparate from the login password, add an
 | |
| C<enable_password> under C<sshcollector> in your configuration file:
 | |
| 
 | |
|  sshcollector:
 | |
|    - ip: '192.0.2.1'
 | |
|      user: oliver
 | |
|      password: letmein
 | |
|      enable_password: myenablepass
 | |
|      platform: IOS

| 
 | |
| 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 => MACADDR, ip => IPADDR }>.
