Error during sending sync messages = 0
Error during receiving sync messages = 0
Invalid prefix index found during message syncing = 0
Errors:
IPv6 Prefix index invalid during pre-pend = 0
Static map entry null in NAT64 proc = 0

Syntax: show nat64 statistics [ all | stateful | stateless | dns-dynamic-learning ]
The all parameter displays all NAT64 statistics
The stateful parameter displays stateful NAT64 statistics only.
The stateless parameter displays stateless NAT46 statistics only.
The dns-dynamic-learning parameter displays DNS dynamic learning statistics.
TABLE 6 Display fields for show nat64 statistics
This field... Displays...
Packet processing:
Pre-proc internal SIP map create = INTERNAL source IP mappings created.
Pre-proc create DIP by removing prefix = NAT64 IPv4 destination IPs extracted.
Pre-proc pending drop = NAT46 (STATELESS) Number of packets dropped due to pending
DNS dynamic discovery.
Stateless IPv6 prefix prepended = Stateless NAT46 V4->V6 packet conversions.
Stateful IPv6 prefix prepended = Stateful NAT64 v4->v6 packet conversions.
6->4 initiate dynamic learning = Stateless: Number of DNS dynamic learnings initiated to
discover IPv4 address.
