This actually means you have 1 virtual interface fec0 representing 2 or more physical interfaces. The load balancing scheme can be assigned by a Catalyst, but low-end models like 2950 and 3550 can only balance traffic based on the least significant bit(s) of MAC-address. > > For instance, do I start configuring an 'ifconfig fec0' device instead of > my usual fxp0? or, does everything pretty much stay the same except > running that extra daemon/command? Here comes the basic setup employed at my site: $ cat /etc/rc.local /sbin/ifconfig bge0 media 100BaseTX mediaopt full-duplex up /sbin/ifconfig bge1 media 100BaseTX mediaopt full-duplex up /usr/sbin/ngctl -f /var/fec0.conf /sbin/ifconfig fec0 inet x.x.x.x netmask 255.255.255.224 up /sbin/route add default x.x.x.x $ cat /var/fec0.conf mkpeer fec dummy fec msg fec0: add_iface "bge0" msg fec0: add_iface "bge1" msg fec0: set_mode_inet > > any docs other then the man pages that I should read through?
