To Enable Autonegotiation Using the ndd Utility
This section describes how to set at least one of the four operational modes and

See “Identifying Device Instances” on page 65 for more information.
2. Select at least one of the four operational mode parameters (adv_100fdx_cap,
adv_100hdx_cap, adv_10fdx_cap, adv_10hdx_cap) that you want to advertise

For example, to make the interface advertise a 10 Mbps, full-duplex mode, you

3. Use the ndd utility to enable autonegotiation mode by setting the
adv_autoneg_cap parameter to 1.
# ndd -set /dev/qfe instance instance-number
# ndd -set /dev/qfe adv_10fdx_cap 1
# ndd -set /dev/qfe adv_autoneg_cap 1
