The first octet in particular, because it has LSB set to 1, will be treated as a multicast address, and many routers and switches will not believe it when it's given as an ARP reply, or as a source address for traffic. I'm hoping it's just an example you substituted so as not to reveal your actual MAC. When making up MAC addresses, keep the LSB of the first octet at zero (required) and set the next bit to 1 (optional, but a good practice). So first octet should be 02, 06, 8a, 9e, etc... any even number, preferably multiple of four, plus two. > ifconfig_xl0="up" > closed_interfaces="lagg0" > ifconfig_lagg0="laggproto failover laggport xl0 laggport wlan0" > ifconfig_lagg0_alias0="inet 10.0.0.4 netmask 0xffffff00" > > I use aliasX to add the address and netmask. > > -- > DE -- David DeSimone == Network Admin == fox@verio.net "I don't like spinach, and I'm glad I don't, because if I liked it I'd eat it, and I just hate it." -- Clarence Darrow This email message is intended for the use of the person to whom it has been sent, and may contain information that is confidential or legally protected.
