Does this mean that, the advertised values for autonegotiation and 10mbs (
fdx and hdx ) should not be set,  as long as the link partner is capable of
100Mbps ?

scenario ( Solaris 2.5.1, Solaris 2.6, E250, Ultra 30 )

I am also facing the througput issues.

I will summarise.

Thank you..

It was an issue with the NIC autonegotiation being enabled. I checked it
with the following commands:

ndd -get /dev/hme link_speed
ndd -get /dev/hme link_mode
ndd -get /dev/hme adv_autneg_cap

Then  I  hardcoded entries in the /etc/system file for Link Speed, Link
and AutoNegotiate as following :

set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0

Now I am getting the well desired 300 MB / Minute speed !!

Best regards
