Original question:
>How can I tell what speed/mode my 10/100 board in 4.0D 4100 is running at?
Summary:
most replied to check the ewa0_mode and the /var/adm/messages file, both of
which I already knew. What I was really looking for was a magic command
that I could run from the OS that would tell me what speed/mode I was
running at that point. No such luck, but I did get some helpful replies.
One:
# ifconfig tu# down speed (10 = single 10, 20 = fd 10, 100 = single 100, 200
= fd 100)
# ifconfig tu# up
or
# /usr/sbin/lan_config -i 'interface name' -s '10|100'
lan_config changes do not remain when the system is rebooted.
As soon as you reboot to console prompt try to set ewa0_mode to
Auto-Negotiate.
Two:
You can set the speed explicitly using the 'speed' parameter in ifconfig.
See the man page for details.
three:
Force the issue at both the NIC and the switch :) Seriously, these
cards are really bad with autonegotiation, otherwise, you are likely
to end up with a duplex mismatch, which just plain ugly:
1) in the SRM (>>> prompt) set ewa0_mode to the right value
From memory:
Twisted-Pair -> 10 half
FastFD -> 100 full
if you run: >>> set ewa0_mode = bogus it will spit out the options
2) add on a speed flag for the IFCONFIG_0 entry in /etc/rc.config
IFCONFIG_0="10.0.0.1 netmask 255.255.255.0 speed 200"
where: 10 => 10 half
20 => 10 full
100 => 100 half
200 => 100 full
3) set the same on the switch
thanks for all the replies.
