Configuring Driver Parameters

By default, autonegotiation mode is enabled for these link parameters. When either
of these parameters are in autonegotiation mode, the
of these parameters are in autonegotiation mode, the
vca
device communicates with
the link partner to negotiate a compatible value and flow control capability. When a
value other than
value other than
auto
is set for either of these parameters, no negotiation occurs
and the link parameter is configured in forced mode. In forced mode, the value for
the
the
speed
parameter must match between link partners. See “Enabling

To Disable Autonegotiation Mode
If your network equipment does not support autonegotiation, or if you want to force
your network
your network
speed
,
duplex
, or
link-clock
parameters, you can disable the
autonegotiation mode on the
vca
device.
1. Set the following driver parameters to the values that are described in the
documentation delivered with your link partner device (for example, a switch):
■
adv-1000fdx-cap
■
adv-1000hdx-cap
■
adv-100fdx-cap
■
adv-100hdx-cap
■
adv-10fdx-cap
■
adv-10hdx-cap
■
adv-asmpause-cap
■
adv-pause-cap
See
for the descriptions and possible values of these parameters.
2. Set the
adv-autoneg-cap
parameter to
0
.
When you change any
ndd
link parameter, a message similar to the following
appears:
Note –
If you disable autonegotiation, you must enable the
