=head1 DESCRIPTION
|
|
|
|
Collect ARP entries from Checkpoint GAIA embedded Systems
|
|
To get this Plugin to work you have to add an User like 'netdisco' with
|
|
'Network admin' right in the GAIA embedded OS
|
|
|
|
This collector uses "C<arp>" as the command for the arp utility on your
|
|
system. If you wish to specify an absolute path, then add an C<arp_command>
|
|
item to your configuration:
|
|
|
|
sshcollector:
|
|
- ip: '192.0.2.1'
|
|
user: netdisco
|
|
password: letmein
|
|
platform: GAIAEmbedded
|
|
arp_command: 'arp'

Retrieve ARP 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 }>.
