Troubleshooting AFT
Symptom 1
When an IPv6 host with a non-IVI address initiates communication with an IPv4 host, AFT fails to perform
address translation.
Solution
1. Enable debugging for AFT and locate the causes based on the debugging information.
2. Verify the translation of the source address is successful based on the debugging information. If not,
the address pool might run out of IP addresses.
3. You can configure a larger address pool or use IP address + port number translation to save the IP
addresses in the address pool.
Symptom 2
When an IPv6 host with an IVI address initiates communication with an IPv4 host, AFT fails to perform
address translation.
Solution
Verify the IVI address complies with the IVI address format. If not, change the address of the IPv6 host or
configure a 6to4 AFT policy.
