Summary: 100 Mb Full Duplex

• Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] [ attachment ]

Thanks to Casper Dik and AYY Choi

The late collision message occured because the sun was not set to full duplex

in /etc/system

                set hme:hme_adv_autoneg_cap=0
                set hme:hme_adv_100hdx_cap=0
                set hme:hme_adv_100fdx_cap=1

or from the command line or /etc/rc2.d script

In case you have multiple instances, you need to select the specific
    hme instance first, e.g., use the following to select hme1:

                ndd -set /dev/hme instance 1

------------------
#!/bin/sh
   
# 100 Mbps optimization (TCP and UDP drivers are not writen for a 100 Mps)
# see SunFastEthernet Adapter 2.0 and Users's Guide (ref 802-6022-10)
ndd -set /dev/tcp tcp_xmit_hiwat 65535
ndd -set /dev/tcp tcp_recv_hiwat 65535
ndd -set /dev/tcp tcp_cwnd_max 65534
     
# set 100 Mbps / full duplex / no negociation
ndd -set /dev/hme adv_100fdx_cap 1
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0
