Probing IP Addresses
When creating a DHCP range, you can now specify how the DHCP server
checks whether an IP address is being used by other hosts by specifying the
new probe parameter, with the command:
create dhcp range=name ip=ipadd number=number policy=name
[gateway=ipadd] [probe={arp|icmp}]
The probe parameter specifies how the DHCP server checks whether an IP
address is being used by other hosts. If arp is specified, the server sends ARP
requests to determine if an address is in use. If icmp is specified, the server
sends ICMP Echo Requests (pings). The default is icmp.
To modify the server’s method for probing IP addresses, use the new
command:
set dhcp range=name probe={arp|icmp}
Note that arp cannot be specified if the range includes a gateway (by specifying
the gateway parameter when it was created), or if the network uses Proxy ARP.
Note that arp cannot be specified if the range includes a gateway (by specifying the
