HP Comware 5 Debug Manual Vol 3

TTL : 127
IPv6 packet is translated to IPv4 packet.
(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.

TTL : 254
IPv4 packet is translated to IPv6 packet.
(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. Output similar to the following example is generated when the
IPv6 host uses FTP to access the IPv4 host under the condition that NAT-PT is disabled on Ethernet
1/1:
<Sysname> debugging natpt event
*Mar 10 14:34:02:547 2008 Sysname DPNATPT/7/EVENT: The outgoing interface is disabled,
dropping packet.
// NAT-PT discarded the packets because NAT-PT was disabled on the outgoing interface.
# Enable NAT-PT event debugging on the NAT-PT device. Output similar to the following example
is generated when the IPv6 host uses FTP to access the IPv4 host under the condition that dynamic
IPv6 NAT-PT mappings are deleted:
<Sysname> debugging natpt event
*Mar 10 14:45:10:562 2008 Sysname DPNATPT/7/EVENT: Cannot get mapped IPv4 source
address, dropping packet.
// NAT-PT discarded the packet because no IPv6 NAT-PT mappings were available.
# Enable NAT-PT ALG debugging on the NAT-PT device. Output similar to the following example
is generated when the IPv6 host uses PORT to access the IPv4 host under the following conditions:
 The IPv6 host has successfully accessed the IPv4 host by using FTP.
 The sessions on the NAT-PT device have been deleted by using the reset session command.
 The IPv6 NAT-PT dynamic mappings have been deleted.
<Sysname> debugging natpt alg
*Mar 10 14:45:10:562 2008 Sysname DPNATPT/7/ALG: Failed to process command EPRT.
// Because FTP control sessions and IPv6 dynamic NAT-PT mappings were removed from Device,
Device could not translate addresses in the PORT commands sent from the IPv6 host.
