HP Comware 5 Debug Manual Vol 3

# Enable NAT-PT packet debugging on the NAT-PT device. When the IPv6 host uses FTP to access
the IPv4 host, output similar to the following example is generated:
<Sysname> debugging natpt packet
*0.1150141 Sysname NATPT/7/debug:
Pro : TCP
TTL : 127
V6 Pkt Translated to V4 Pkt
(1000::0001 : 1041 - 1001::0303:0301 : 21)
(5.1.1.1 : 1041 - 3.3.3.1 : 21)
// NAT-PT translated the source and destination IPv6 addresses in the received IPv6 TCP packet
into IPv4 addresses.
*0.1150141 Sysname NATPT/7/debug:
Pro : TCP
TTL : 254
V4 Pkt Translated to V6 Pkt
(3.3.3.1 : 21 - 5.1.1.1 : 1041)
(1001::0303:0301 : 21 - 1000::0001 : 1041)
// NAT-PT translated the source and destination IPv4 addresses in the received IPv4 TCP packet
into IPv6 addresses.
# Enable NAT-PT event debugging on the NAT-PT device. When the device receives an IPv4
packet, but no matching NAT-PT entry exists for the destination IPv4 address, output similar to the
following example is generated:
<Sysname> debugging natpt event
*0.478281 Sysname NATPT/7/debug:
Mapping does not exist for the v4 destination address 111.255.255.255
// NAT-PT found no NAT-PT entry for IP address 111.255.255.255.
*0.478281 Sysname NATPT/7/debug:
The v4 pkt is not intended for NATPT. Returning the pkt back to V4 stack
// NAT-PT sent the IPv4 packet back to the IPv4 protocol stack because the packet was not
intended for NAT-PT.
# Enable NAT-PT event debugging on the NAT-PT device. When the device receives an IPv6
packet, but no matching IPv6 prefix exists for the destination IPv6 address, output similar to the
following example is generated:
<Sysname> debugging natpt event
*0.825484 Sysname NATPT/7/debug:
V6 dest addr does not contain configured prefix
// NAT-PT did not find a matching prefix for the destination address of the IPv6 packet.
*0.825484 Sysname NATPT/7/debug:
The v6 pkt is not intended for NATPT. Returning the pkt back to V6 stack
// NAT-PT sent the IPv6 packet back to the IPv6 protocol stack because it was not intended for
NAT-PT.
