It works fine -
bge0 connected to GIGE switch, bge1 is not connected

# snmpget -c pub -v 1 localhost ifSpeed.1
IF-MIB::ifSpeed.1 = Gauge32: 1000000000
# snmpget -c pub -v 1 localhost ifHighSpeed.1
IF-MIB::ifHighSpeed.1 = Gauge32: 1000

# ifconfig bge1 up
# ifconfig bge1 media auto
# snmpget -c pub -v 1 localhost ifSpeed.2
IF-MIB::ifSpeed.2 = Gauge32: 0
# snmpget -c pub -v 1 localhost ifHighSpeed.2
IF-MIB::ifHighSpeed.2 = Gauge32: 0

# ifconfig bge1 media 10baseT/UTP
# snmpget -c pub -v 1 localhost ifSpeed.2
IF-MIB::ifSpeed.2 = Gauge32: 10000000
# snmpget -c pub -v 1 localhost ifHighSpeed.2
IF-MIB::ifHighSpeed.2 = Gauge32: 10

# ifconfig bge1 media 100baseTX
# snmpget -c pub -v 1 localhost ifSpeed.2
IF-MIB::ifSpeed.2 = Gauge32: 100000000
# snmpget -c pub -v 1 localhost ifHighSpeed.2
IF-MIB::ifHighSpeed.2 = Gauge32: 100

It might be not important, but if adapter is in DOWN state
snmp may show different media:

1. Adapter is Down. ifconfig shows - media: Ethernet autoselect (none)
Snmp shows ifSpeed 0.
2. # ifconfig bge1 media 100baseTX.
ifconfig shows - media: Ethernet 100baseTX (none)
Snmp still shows ifSpeed 0.
3. # ifconfig bge1 up 
ifconfig shows - media: Ethernet 100baseTX (none)
snmp shows ifSpeed 100000000
4. # ifconfig bge1 down
snmp still shows ifSpeed 100000000
after running "ifconfig bge1" snmp shows ifSpeed 0

So sometimes ifconfig helps to change baudrate
if adapter in DOWN state.

Thanks,
Oleg
