The E3000 does have full duplex 100Mb/s, it isn't enabled by default.
(FAQ)", "Subject: 12.3)". To find out...
# ndd /dev/hme \?
as a reminder, then:
# ndd /dev/hme link_speed link_mode
link_speed: 0=10mbps, 1=100mbps
link_mode: 0=half-duplex, 1=full-duplex
There are several ways of changing the default settings and force
full-duplex mode; you may need to alter your
switch settings as well.
Setting through /etc/system
Setting with ndd
ndd -set /dev/hme adv_autoneg_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_100fdx_cap 1
In case you have multiple instances (e.g. Quad), you need to select the
instance first, e.g., use the following to
ndd -set /dev/hme instance 1
If you need to query the device, you can interrogate various variables
such as ``link_status'', ``link_speed'', etc.
Some patches may be required
102979 for 2.5
104212 for 2.5.1
Sun trunking s/w is needed to make the Quad Card run as 4 combined
channels, but is a normal thing to do.
Thanks again to all those who answered, too numerous to mention - you
know who you are :)
