 | |
| 
 | |
| =head1 DESCRIPTION
 | |
| 
 | |
| 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.

| 
 | |
| 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 }>.
