Network-Enabled Modes
Notes:
• For all network-enabled modes described below, the PRO2 will set an auto-configured IPv6 address, and if
IPv6 router announcements are active, a stateless DHCP IPv6 address will also be set. Further, in all
network-enabled modes, at least one IPv4 or one IPv6 address will be active.
• For maximum backward compatibility, the default network mode is “IPv4 only”.
Descriptions for the network-enabled modes:
• Network disabled – No IPv4 or IPv6 addresses available.
• IPv4 only, DHCP disabled (static IPv4) – If the IPv4 Static Address and Net Mask of the PRO2 are valid,
they will be set.
•
IPv4 only, DHCP enabled (DHCP IPv4)
– The PRO2 will try to resolve an IPv4 DHCP address. If a DHCP
address cannot be obtained after 90 seconds, the PRO2 can: (1) optionally fall back to its static IPv4
settings, or (2) indefinitely wait to acquire an address based on DHCP configuration settings
. This setting
is the default.
• Dual IPv6/IPv4, DHCP disabled (static IPv6/IPv4) – If the IPv6 Static Address and prefix of the PRO2 are
valid, they will be set. Otherwise, the PRO2 will attempt to use DHCPv6 to obtain an IPv6 address. In
addition, if the IPv4 Static Address and Net Mask of the PRO2 are valid, they will be set.
• Dual IPv6/IPv4, DHCP enabled (DHCP IPv6/IPv4) – The PRO2 will try to resolve both its IPv6 and IPv4
addresses by DHCP. If both DHCP requests are answered, the primary DNS server of the PRO2 will
become the primary IPv6 DNS server, and the secondary DNS server of the PRO2 will become the
primary IPv4 DNS server. If only one of the DHCP requests is answered, the DNS servers of the PRO2 will
map to the primary and secondary DNS server from that request. If a DHCP address cannot be obtained
after 90 seconds, the PRO2 can: (1) optionally fall back to its static IPv4 and/or IPv6 settings, or (2)
indefinitely wait to acquire an address based on DHCP configuration settings.
