ETHERMULTILINK(8) ETHERMULTILINK(8)
NAME
ethermultilink - switch between multiple interfaces on a
bridge
SYNOPSIS
ethermultilink primary secondary [ secondary ]... >
/net/bridge0/ctl
DESCRIPTION
Ethermultilink takes a primary ethernet interface and a list
of secondary interfaces in increasing priority order. It
checks the link status of the secondary interfaces and if
any are link-active, bridges the primary and the highest
priority secondary interface together by outputting
bridge(4) commands on standard output. The link status of
all the secondary interfaces is checked once per second and
the commands to change the active secondary are output as
needed.
EXAMPLE
# make the bridge
bind -a '#B' /net
# mount the ethernet
bind -a '#l0' /net
# mount the wifi
bind -a '#l1' /net
# roam between wifi and ethernet
ethermultilink /net/ether1 /net/ether0 > /net/bridge0/ctl
# setup ip on the primary
ip/ipconfig ether /net/ether1
