Solaris 5.9 "Full or Half Duplex"

Cuz you're using the wrong ndd options.

# eri - found on newer Sun Blades and Sun Fires
#Add these lines to /etc/system
set eri:adv_100T4_cap = 0
set eri:adv_100fdx_cap = 1
set eri:adv_100hdx_cap = 0
set eri:adv_10fdx_cap = 0
set eri:adv_10hdx_cap = 0
set eri:adv_autoneg_cap = 0

Or:

# using a ndd startup script if you do not want to add to /etc/system
#!/bin/sh
ndd -set /dev/eri adv_100T4_cap 0
ndd -set /dev/eri adv_100fdx_cap 1
ndd -set /dev/eri adv_100hdx_cap 0
ndd -set /dev/eri adv_10fdx_cap 0
ndd -set /dev/eri adv_10hdx_cap 0
ndd -set /dev/eri adv_autoneg_cap 0

So to check:

ndd -get /dev/eri adv_100T4_cap
ndd -get /dev/eri adv_100fdx_cap
ndd -get /dev/eri adv_100hdx_cap
ndd -get /dev/eri adv_10fdx_cap
ndd -get /dev/eri adv_10hdx_cap
ndd -get /dev/eri adv_autoneg_cap

PsiCop,

I took a look at that script.  I don't see any logic to handle the eri interfaces.  Am I missing something ?

eri NICs are caught in the last elsif branch, which handles all NIC types except ce, bgp, iprb and le.

My /etc/system configuration is fine. I am just trying to fine the quick and dirty way(command syntax) to find whether my SunBlade is currently running at "full or half duplex."

I was able to retrieve the desired information(full or half duplex) via "ndd -get /dev/eri /?". Thanks for your help.

This script requires that you are root but it is great.  I got this off of SUN's web sight:
