SYNOPSIS
.In netgraph/ng_fec.h
DESCRIPTION
The fec node implements Ethernet port trunking using Cisco Fast EtherChannel protocol. Upon creation, node creates a network interface associated with it. Interfaces are named "fec0", "fec1", etc. New node takes first available unit.
HOOKS
The fec node accepts any hooks. However it does not use them. Under normal operation, 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. Target interface name is passed as a string argument. | | NGM_FEC_DEL_IFACE("del_iface") | | | Remove interface from the trunk. Target interface name is passed as a string argument. | |
The following control messages define forwarding method for a node: | NGM_FEC_MODE_INET("set_mode_mac") | | | Forwarding decisions will be made on destination link layer MAC addresses. | | NGM_FEC_MODE_MAC("set_mode_inet") | | | Forwarding decisions will be made on destination IP addresses. | |
SHUTDOWN
This node shuts down upon receipt of a NGM_SHUTDOWN control message.
EXAMPLES
This example script creates a fec node, attaches four Ethernet interfaces to it and sets forwarding method based on IP address:
/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
