.Sh NAME
|
|
.Nm ng_fec
|
|
.Nd netgraph Fast EtherChannel node
|
|
.Sh SYNOPSIS
|
|
.In netgraph/ng_fec.h
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm fec
|
|
node implements Ethernet port trunking using the
|
|
.Dq Cisco Fast EtherChannel
|
|
protocol.
|
|
Upon creation, a
|
|
.Nm fec
|
|
node creates a network interface associated with it.
|
|
Interfaces are named
|
|
.Dq Li fec0 ,
|
|
.Dq Li fec1 ,
|
|
etc.
|
|
New nodes take the first available unit.
|
|
.Sh HOOKS
|
|
The
|
|
.Nm fec
|
|
node accepts any hooks.
|
|
However it does not use them.
|
|
Under normal operation, a
|
|
.Nm fec
|
|
node should not have any hooks.
|
|
.Sh CONTROL MESSAGES
|
|
Interface membership in the FEC group is configured with the following
|
|
control messages:
|
|
.Bl -tag -width indent
|
|
.It Dv NGM_FEC_ADD_IFACE Pq Dq Li add_iface
|
|
Attach interface to the FEC group.
|
|
The target interface name is passed as a string argument.
|
|
.It Dv NGM_FEC_DEL_IFACE Pq Dq Li del_iface
|
|
Remove interface from the trunk.
|
|
The target interface name is passed as a string argument.
|
|
.El
|
|
.Pp
|
|
The following control messages define the forwarding method for a node:
|
|
.Bl -tag -width indent
|
|
.It Dv NGM_FEC_SET_MODE_MAC Pq Dq Li set_mode_mac
|
|
Forwarding decisions will be based on the link-layer MAC address of the destination.
|
|
.It Dv NGM_FEC_SET_MODE_INET Pq Dq Li set_mode_inet
|
|
Forwarding decisions will be based on the IP address of the destination.
|
|
.El
|
|
.Sh SHUTDOWN
|
|
This node shuts down upon receipt of a
|
|
.Dv NGM_SHUTDOWN
|
|
control message.
|
|
.Sh EXAMPLES
|
|
The following example script creates an
|
|
.Nm fec
|
|
node, attaches four Ethernet interfaces to it and
|
|
sets the forwarding method to be IP-address based:
|
|
.Bd -literal -offset indent
|
|
/usr/sbin/ngctl -f- << SEQ
|
|
mkpeer fec dummy fec
|
|
msg fec0: add_iface "dc0"
|
|
msg fec0: add_iface "dc1"

|
msg fec0: add_iface "dc2"
|
