9Collect ARP entries from Checkpoint GAIA embedded Systems
10To get this Plugin to work you have to add a user like 'netdisco' with
11'Network admin' rights in the GAIA embedded OS.
12
13This collector uses "C<arp>" as the command for the arp utility on your
14system. If you wish to specify an absolute path, then add an C<arp_command>
15item to your configuration:

17 device_auth:
18   - tag: sshgaia
19     driver: cli
20     platform: GAIAEmbedded
21     only: '192.0.2.1'
22     username: oliver
23     password: letmein
24     arp_command: 'arp'

41Retrieve ARP entries from device. C<$host> is the hostname or IP address
42of the device. C<$ssh> is a Net::OpenSSH connection to the device.
43
44Returns a list of hashrefs in the format C<{ mac =E<gt> MACADDR, ip =E<gt> IPADDR }>.
