DRAFT: BROCADE CONFIDENTIAL
TCP 4->6 = # stateless NAT64 TCP IPv4 packets converted to IPv6.
UDP 6->4 = # stateless NAT64 UDP IPv6 packets converted to IPv4.
UDP 4->6 = # stateless NAT64 UDP IPv4 packets converted to IPv6.
Static pending or error in entry drop =
Stateful Statistics:
TCP 6->4 = The number of IPv6 TCP packets that have been translated to
IPv4.
TCP 4->6 = The number of IPv4 TCP packets that have been translated to
IPv6.
TCP reverse no session drop = The number of TCP packets that were dropped due to no
reverse session being present.
UDP 6->4 = The number of IPv6 UDP packets that have been translated to
IPv4.
UDP 4->6 = The number of IPv4 UDP packets that have been translated to
IPv6.
UDP reverse no session drop = The number of UDP packets that were dropped due to no
reverse session being present
NAT64 NAT pool Statistics:
6->4: TCP: NAT port allocated = The total number of ports allocated from the NAT64 IPv4 pool.
6->4: TCP: NAT port not available = The total number of occurrences when no NAT64 IPv4 pool port
was available.
NAT port freed = The total number of ports allocated from NAT64 IPv4 pool that
have been freed up.
NAT64 HA Statistics:
Message sync sent = Number of sessions synced to HA peer.
Message sync received = Number of NAT64 sessions received from HA peer.
Error during sending sync messages = # of errors encountered while syncing NAT64 sessions.
Error during receiving sync messages = # of sync messages with errors (usually indicates configuration
mismatch).
Invalid prefix index found during message
syncing =
# of times NAT64 prefix in session received from peer not
configured on device.
Errors
IPv6 Prefix index invalid during pre-pend = # times when IPv6 prefix was not found when converting IPv4 ->
IPv6 packets.
Static map entry null in NAT64 proc = Not used.
Get MTU on V6 outgoing port error = Not used.
Abnormal packets:
Embedded IPv4 address not unicast = IPv4 address embedded in the IPv6 prefix is a multi-cast /
broadcast address.
SIP contains IPv6 prefix = Packet received has source IP in NAT64 prefix.
