Setting Forced Mode
This section describes how to set forced mode (not capable of auto-
negotiation).
▼ To select one of the five local transceiver capabilities and set
the mode to forced mode
1. Select one of the following capabilities: adv_100T4_cap,
adv_100fdx_cap, adv_100hdx_cap, adv_10fdx_cap, or
adv_10hdx_cap, and set its value to 1.
If you select more than one of the local transceiver capabilities, the driver
selects the one that is highest in the priority order (see the footnote from
Table 3-5 on page 13).
2. Set the local transceiver capabilities advertised by the hardware to forced
mode = 0, which is not capable of auto-negotiation: adv_autoneg_cap 0
Use the ndd utility as described in “Using the ndd Utility in Interactive
Mode” on page 22.

adv_100fdx_cap, adv_100hdx_cap, adv_10fdx_cap, adv_10hdx_cap)
that you want to advertise to the remote system, and set its value to 1.
2. Set the local transceiver capabilities advertised by the hardware to 1, the
auto-negotiation setting: adv_autoneg_cap 1
Use the ndd utility as described in “Using the ndd Utility in Interactive
