Anyway, it seems bsnmpd insists these are 10 mbps interfaces? AN>Why so? The driver reports a speed of 10Mbits/sec. ifHighSpeed is ifi_baudrate divided by 10^6 (and rounded). This is the default set by ether_ifattach() if the driver did not set another value. It seems that bge never sets that value so you end up with the default. This looks like a bug. harti
