Let us look at an example for NAT444 user-based UDP port translation mapping:
[UserbasedA - 10.0.0.1 Broadband - 100.1.1.1 - 2048 3071 - -]
The description for this example is as follows:
OL-32659-01
Cisco IOS XR Carrier Grade NAT Configuration Guide for the Cisco CRS Router, Release 5.2.x
Syslog Message Format
Description
Specifies the identifier for the transport layer protocol.
Select any one of the values for L4 from the
following:
• 1 for ICMP
• 6 for TCP
• 17 for UDP
• 47 for GRE
Specify the private IPv4 address.
The Inside vrf is essential to identify the subscriber.
Even though multiple subscribers connected to the
router might have the same source IP, they might be
placed in different VRFs. Hence the VRF name and
the original source IP together helps to identify a
subscriber. Ensure that the VRF name is not more
than 32 characters in length.
Specifies the IPv6 source address of the tunnel in case
of DS Lite.
Specifies the public IPv4 address post translation.
Specifies the source port number before translation.
This is not applicable for the UserbasedA and
UserbasedW events.
Specifies the first source port after translation.
Specifies the last source port after translation. This
is applicable only for the UserbasedA and
UserbasedW events.
Specifies the destination IP recorded in the syslogs
for the SessionbasedAD and SessionbasedWD events.
Specifies the destination port recorded in the syslogs
for the SessionbasedAD and SessionbasedWD events.
