NG_FEC(4)              FreeBSD Kernel Interfaces Manual              NG_FEC(4)

NAME
     ng_fec - netgraph Fast EtherChannel node

SYNOPSIS
     #include <netgraph/ng_fec.h>

DESCRIPTION
     The fec node implements Ethernet port trunking using the ``Cisco Fast
     EtherChannel'' protocol.  Upon creation, a fec node creates a network
     interface associated with it.  Interfaces are named ``fec0'', ``fec1'',
     etc.  New nodes take the first available unit.

HOOKS
     The fec node accepts any hooks.  However it does not use them.  Under
     normal operation, a fec node should not have any hooks.

CONTROL MESSAGES
     Interface membership in the FEC group is configured with the following
     control messages:

     NGM_FEC_ADD_IFACE (``add_iface'')
             Attach interface to the FEC group.  The target interface name is
             passed as a string argument.

     NGM_FEC_DEL_IFACE (``del_iface'')
             Remove interface from the trunk.  The target interface name is
             passed as a string argument.

     The following control messages define the forwarding method for a node:

     NGM_FEC_SET_MODE_MAC (``set_mode_mac'')
             Forwarding decisions will be based on the link-layer MAC address
             of the destination.

     NGM_FEC_SET_MODE_INET (``set_mode_inet'')
             Forwarding decisions will be based on the IP address of the
             destination.

SHUTDOWN
     This node shuts down upon receipt of a NGM_SHUTDOWN control message.

EXAMPLES
     The following example script creates an fec node, attaches four Ethernet
     interfaces to it and sets the forwarding method to be IP-address based:

           /usr/sbin/ngctl -f- << SEQ
                   mkpeer fec dummy fec
                   msg fec0: add_iface "dc0"
                   msg fec0: add_iface "dc1"
                   msg fec0: add_iface "dc2"
                   msg fec0: add_iface "dc3"
                   msg fec0: set_mode_inet
           SEQ
