upgrade.

IPv6 log server
Indicates the IP address and port of the remote logging machine to which the phone
sends log messages.
IPv6 CAPF server
Indicates the method that the phone uses to get the IPv6-only address.

server or from SLAAC by RA sent by the IPv6-enabled router. And if DHCPv6 is
disabled, the phone will not have any stateful (from DHCPv6 server) or stateless
(from SLAAC) IPv6 address.
Unlike DHCPv4, even DHCPv6 is disabled the phone can still generate a
SLAAC address if autoconfigure is enabled.
Note
DHCPv6
Displays the current IPv6-only address of the phone.
Two address formats are supported:
•

single group represented by a double colon.
