ng_fec

NG_FEC(4)						   BSD 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
