The HA interface cannot be configured for IPv6.
Only the parent interface of a SwitchPort group can be configured as an IPv6 interface; hence, all children of a switch port group must be excluded from this list.
Zone and Layer 2 Bridge groups are shared configurations between IPv4 and IPv6 on an interface. When they are configured on the IPv4 side, the IPv6 side of the interface uses the same configuration.
Default Gateway and DNS Servers can only be configured for WAN zone interfaces.
Wire mode is supported for IPv6, but you can not edit any settings. Instead, SonicOS uses the same configuration options set for IPv4.
