Answers from all can be summerised to following:

----------------------------------------------------------------------------
--------------
On SRM console:

>>> set ewa0_mode FastFD (providing your NIC is ewa0)
----------------------------------------------------------------------------
-----------------
>From UNIX:

# lan_config -i tu0 -m utp -s 100 -x 1 (again, this is for DEC Tulip
card)

Place the above line
in /etc/inet.local to make the change permanant.

----------------------------------------------------------------------------
--------------
ifconfig tu0 down
ifconfig tu0 speed 100
ifconfig tu0 up

this will put you at 100 half-duplex.

10 -> 10-half
20 -> 10-full
100 -> 100-half
200 -> 100-full


Then to have it stay in effect across boots,add it to IFCONFIG_N entry in
/etc/rc.config.

----------------------------------------------------------------------------
---------------
# hwmgr -set attr -id 16 -a media_speed=100

----------------------------------------------------------------------------
----------------

After setting the console Variable (ewa0_mode) to FastFd , lanconfig,ifconfi
or hwmgr can be used to set the value in OS.



Hi all,

We have got a DE500 network card on an alpha 4000 running DGUX 5.1.

Currently it is running at 10MB/s.
Though the Network card supports 10/100 when I tried to change the speed
using following command(s)
it failed.

        # ifconfig tu0 down

        # hwmgr -set attr -id 16 -a media_speed=100

        hwmgr: 16: Attribute "media_speed" does not support this operation.

I tried to set the speed using "sysman" but still the same result.

I Checked CONSOLE Variables .. but could not find any thing relevent.
