option stp
Set this option to on to use the Spanning Tree Protocol (STP). The default is on.
STP is used to detect bridging loops. Set this option to off only if the bridging peers do not support
the Spanning Tree Protocol or if you are certain that no bridging loops could exist. When STP is
disabled on an interface, any STP packets received on that interface are ignored.
Note: The Spanning Tree Protocol adds a 40-second delay each time the ADSL or ATM link
comes up while the interface determines if there is a bridging loop.
pppoeOnly
Set this option to on to limit this Ethernet port to bridging PPPoE traffic only. If the option is set to
off, then the port can bridge any traffic, including PPPoE traffic. The default is off.
port# Ethernet port number (0 or 1). The default is 0.
Examples:
The following command turns off the spanning tree protocol for Ethernet port 0.
eth br options stp off
The following command configures Ethernet port 1 so that only PPPoE traffic is bridged through it.
eth br options pppoeonly on 1
