with the remote end of the link (link partner) to select a common mode of operation
for the speed,duplex, and link-clock parameters. The link-clock parameter
is applicable only if the board is operating at a 1000 Mbps. The vca device can also
be configured to operate in forced mode for each of these parameters.
Caution – Toestablish a proper link, both link partners must operate in either
autonegotiation or forced mode for each of the speed,duplex, and link-clock
(1000 Mbps only) parameters. If both link partners are not operating in the same
mode for each of these parameters, network errors will occur.See “Enabling
Autonegotiation or ForcedMode for Link Parameters With the OpenBoot PROM” on
page41.
