Usage guidelines
The ACS can use the provision code to identify services assigned to each CPE. For correct configuration
deployment, make sure the same provision code is configured on the CPE and the ACS. For information
about the support of your ACS for provision code, see the ACS documentation.
The CPE can have only one provision code. If you use the command multiple times, the final provision
code takes effect.
Examples
# Set the provision code to HP20130525.
<Sysname> system
[Sysname] cwmp
[Sysname-cwmp] cwmp cpe provision-code HP20130525
cwmp cpe stun enable
Use cwmp cpe stun enable to enable NAT traversal for the connection requests from the ACS to reach the
CPE through a NAT gateway.
Use undo cwmp cpe stun enable to restore the default.
Syntax
cwmp cpe stun enable
undo cwmp cpe stun enable
Default
NAT traversal is disabled for CWMP.

Usage guidelines
Connection requests initiated from the CPE can reach the ACS through a NAT gateway without NAT
traversal. However, for the connection request initiated from the ACS to reach the CPE, you must enable
NAT traversal on the CPE when a NAT gateway resides between the CPE and the ACS.
The NAT traversal feature complies with Simple Traversal of UDP Through NATs (STUN), RFC 3489. The
feature enables the CPE to do the following:
• Discovers the NAT gateway.
• Obtains an open NAT binding (a public IP address and port binding) through which the ACS can
send unsolicited packets.
The CPE sends the binding to the ACS when it initiates a connection to the ACS. For the connection
requests sent by the ACS at any time to reach the CPE, the CPE maintains the open NAT binding.
For more information about NAT, see Layer 3—IP Services Configuration Guide.
