Description

Specify that the don’t fragment (DF) bit for IPv4 packet headers is cleared when the packet length is less than 1280 bytes. Use this statement when configuring stateful NAT64, deterministic NAPT64, and 464XLAT. This prevents unnecessary creation of an IPv6 fragmentation header when translating IPv4 packets that are less than 1280 bytes.
