Capturing Dump Information - Sun Microsystems GigabitEthernet PCI Adapter User Manual

For example, if you need to set Link Negotiation "off" for adapter 2 and increase the
TCP/IP values, you could place the following lines in the /ect/rc2.d start-up file:
# !/sbin/sh
# Local kernel modifications
#
case "$1" in
'start')
'stop')
*)
esac

Capturing Dump Information

The dump_nic command should be used if an adapter stops operating for any
reason. The dump contains internal adapter state information which can be used to
troubleshoot problems.
To take a dump of an adapter's state information, once the adapter has stopped
operating:
1. Select the proper adapter instance.
# ndd -set /dev/vge instance <value>
2. Set the adapter to dump state information in the case of a system core dump.
# ndd -set /dev/vge dump_nic 1
