 | |
| 
 | |
| Collect ARP entries from Check Point VSX
 | |
| 
 | |
| This collector uses "C<arp>" as the command for the arp utility on your

| 
 | |
|  sshcollector:
 | |
|    - ip: '192.0.2.1'
 | |
|      user: oliver

|      expert_password: letmein2
 | |
|      platform: CPVSX

| 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 } >>.
