Collect ARP entries from F5 BigIP load balancers. These are Linux boxes, but feature an additional, proprietary IP stack which does not show up in the standard SNMP ipNetToMediaTable.

These devices also feature a CLI interface similar to IOS, which can either be set as the login shell of the user, or be called from an ordinary shell. This module assumes the former, and if "show net arp" can't be executed, falls back to the latter.


arpnip($host, $ssh)

Retrieve ARP entries from device. $host is the hostname or IP address of the device. $ssh is a Net::OpenSSH connection to the device.

Returns a list of hashrefs in the format { mac = MACADDR, ip => IPADDR }>.
