| 32 | .SH DESCRIPTION | |
| 33 | The | |
| 34 | .B ip fou | |
| 35 | commands are used to create and delete receive ports for Foo-over-UDP | |
| 36 | (FOU) as well as Generic UDP Encapsulation (GUE). | |
| 37 | .PP | |
| 38 | Foo-over-UDP allows encapsulating packets of an IP protocol directly | |
| 39 | over UDP. The receiver infers the protocol of a packet received on | |
| 40 | a FOU UDP port to be the protocol configured for the port. | |
| 41 | .PP | |
| 42 | Generic UDP Encapsulation (GUE) encapsulates packets of an IP protocol | |
| 43 | within UDP and an encapsulation header. The encapsulation header contains the | |
| 44 | IP protocol number for the encapsulated packet. | |
| 45 | .PP | |
| 46 | When creating a FOU or GUE receive port, the port number is specified in | |
| 47 | .I PORT | |
| 48 | argument. If FOU is used, the IP protocol number associated with the port is specified in | |
| 49 | .I PROTO | |
| 50 | argument. | |
| 51 | .PP | |
| 52 | A FOU or GUE receive port is deleted by specifying | |
| 53 | .I PORT | |
| 54 | in the delete command. | |
