SUMMARY: link speed on a V210

Thanks everyone,

The best way to see the current duplex setting of a bge interface is with
the kstat command, here are a couple examples that work:

kstat bge:0 | grep duplex
kstat -m bge -n bge0

For a list of all parameters accepted by the ndd command (clearly stated in
the man page:) use the following command:

ndd /dev/bge0 \?

The parameter I was looking for was link_duplex.  However, it looks as
though a 1 means half duplex and a 2 means full duplex.  This can be
confusing if you're used to the hme interfaces that use 0 and 1 for the
duplex settings.  Anyway, I was able to determine that the system was
coming up at 100 half duplex, and after getting the correct parameters, I
made the following startup script which successfully forced it to 100 full:

# cat /etc/init.d/interface
#!/sbin/sh

case "$1" in
'start')
        echo "Forcing bge interface to 100 MBit Full Duplex... \c"
        ndd -set /dev/bge0 adv_autoneg_cap 0
        ndd -set /dev/bge0 adv_1000fdx_cap 0
        ndd -set /dev/bge0 adv_1000hdx_cap 0
        ndd -set /dev/bge0 adv_100T4_cap 0
        ndd -set /dev/bge0 adv_100fdx_cap 1
        ndd -set /dev/bge0 adv_100hdx_cap 0
        ndd -set /dev/bge0 adv_10fdx_cap 0
        ndd -set /dev/bge0 adv_10hdx_cap 0
        echo "done"
        ;;

*)
        echo "Usage: $0 { start }"
        exit 1
        ;;
esac
exit 0

Thank you to everyone for their quick and helpful replies!

Hey everyone,

I have just set up a Sun Fire V210 server.  I want to make sure that the
interface is getting set to 100 full duplex.  However, this interface does
not seem to accept the link_mode option to the ndd command:

# ndd -get /dev/bge0 link_speed
100

# ndd -get /dev/bge0 link_status
1

# ndd -get /dev/bge0 link_mode
operation failed: Invalid argument

# ndd -get /dev/bge link_mode
operation failed: Invalid argument


Does anybody know how I can check the duplex setting on this interface?
According to the boot messages, it's coming up as half duplex, but I'd like
to know how to confirm this.  Thanks,

PJ
