cegwctl - CAN - Ethernet Gateway Control Utility

SYNOPSIS

cegwctl [ __-f__ | __--can-fd__ ] [ __-t__ TYPE | __--type__=_TYPE_ ] [ __-b__ | __--bidirectional__ ] add route SRC DST

cegwctl [ __-f__ | __--can-fd__ ] [ __-t__ TYPE | __--type__=_TYPE_ ] add dev [NAME]

TYPE := { none | eth | net | udp | tcp }

cegwctl del route ID

cegwctl del dev NAME

cegwctl route

DESCRIPTION

Control Utility for the ce_gw Kernel Programm.

OPTIONS

__-b__, __--bidirectional__

If you add a route from SRC to DST, there will be also add the same route back from DST to SRC.

__-f__, __--can-fd__
