.TH ETHERMULTILINK 8 .SH NAME ethermultilink \- switch between multiple interfaces on a bridge .SH SYNOPSIS .B ethermultilink .I primary .I secondary [ .I secondary ]... .B > /net/bridge0/ctl .SH DESCRIPTION Ethermultilink takes a .I primary ethernet interface and a list of .I 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 .IR 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. .SH EXAMPLE .EX # 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 .EE .SH SOURCE .B /rc/bin/ethermultilink .SH "SEE ALSO" .IR bridge (3).
