nfdc-face

SYNOPSIS

nfdc face [list]
nfdc channel [list]
nfdc create [-P] <faceUri>
nfdc destroy <faceId|faceUri>

DESCRIPTION

In NFD, a face is the generalization of network interface. It could be a physical network interface to communicate on a physical link, an overlay communication channel between NFD and a remote node, or an inter-process communication channel between NFD and a local application.

The nfdc face list command shows a list of faces, their properties, and statistics.

The nfdc channel list command shows a list of channels. Channels are listening sockets that can accept incoming connections and create new faces.

The nfdc create command creates a new UDP or TCP face.

The nfdc destroy command destroys an existing face. It has no effect if the specified face does not exist.

OPTIONS

-P Creates a “permanent” rather than persistent face. A persistent face is closed when a socket error occrs. A permanent face is kept alive upon socket errors, and is closed only upon nfdc destroy command.
<faceUri>

An URI representing the remote endpoint of a face. Its syntax is:

  • udp[4|6]://<IP-or-host>[:<port>]
  • tcp[4|6]://<IP-or-host>[:<port>]

When a hostname is specified, a DNS query is used to obtain the IP address.

<faceId>
Numerical identifier of the face. It is displayed in the output of nfdc face list and nfdc create commands.
