Enabling MIP NAT Traversal
MIP NAT traversal must be enabled for the desired HA service on the system.
Important:
Commands used in the configuration samples in this section provide base functionality to the extent
that the most common or likely commands and/or keyword options are presented. In many cases, other optional
commands and/or keyword options are available. Refer to the Command Line Interface Reference for complete
information regarding all commands.

information regarding all commands.
To enable MIP NAT traversal, set parameters by applying the following example configuration:
configure
context <context_name>
ha-service <name>
nat-traversal
end
Notes:
Optionally, you can configure the HA to accept requests when NAT is not detected but the Force (F) bit is set in
the RRQ with the UDP Tunnel Request by entering the following command: nat-traversal force-accept
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode
command

save configuration
. For additional information on how to verify and save configuration files, refer to the
System Administration Guide and the Command Line Interface Reference.
Viewing MIP NAT Traversal Statistics
Use the following commands in exec mode to list statistics that include information about MIP NAT Traversal:
monitor {protocol | subscriber}
- Use the MIP Tunnel option to trace IP-UDP tunneled datagrams.
show ha-service
service_name
- Shows the MIP NAT Traversal configuration for the specified HA
service.
show mipha statistics
- Lists IP-UDP tunnel statistics for Home Agent calls specified.
show mipha full
- Displays NAT, UPD, and encapsulation information for Home Agent calls specified.
show subscribers full
- Displays NAT, UPD, and encapsulation information for the subscribers specified.
{show | clear} subscribers ccoa-only
- Show or clear sessions for subscribers that registered a MIP
colocated COA directly with the HA.
{show | clear} subscribers mip-udp-tunnel-only
- Show or clear sessions for subscribers that
negotiated MIP UDP tunneling with the HA.
Refer to Exec Mode Commands chapter in theCommand Line Interface Reference for details on using these commands.
