IPv6
IPv6 addressing is supported on the phone. A valid IPv6 address is 128 bits in length, including the subnet
prefix.
IPv6 addresses must be in one of the following formats:
•
Eight sets of four hexadecimal digits separated by colons where the leftmost digits represent the
highest-order bits. Any leading or trailing zeros in each group may be omitted.
•
Compressed format to collapse a single run of consecutive zero groups into a single group represented
by a double colon. Note that this can only be done once in an address.
Before IPv6 setup options can be configured on your device, IPv6 must be enabled and configured in Cisco
Unified Communication Administration. The following device configuration fields apply to IPv6 configuration:
•
IP Addressing Mode
•
IP Addressing Mode Preference for Signalling
If IPv6 is enabled in the Unified cluster, the default setting for IP addressing mode is IPv4 and IPv6 (dual-stack).
In this addressing mode, the phone will acquire and use one IPv4 address and one IPv6 address. It can use
the IPv4 and the IPv6 address as required for media. The phone uses either the IPv4 or IPv6 address for call
control signalling to Unified CM.
