NG_FEC(4) 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 desti- nation. SHUTDOWN This node shuts down upon receipt of a NGM_SHUTDOWN control message. EXAMPLES The following example script creates an fec node, attaches four Ether- net 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 SEE ALSO netgraph(4) HISTORY The fec node type was implemented in FreeBSD 5.0.
