I have an Ultra-10 running Solaris 8. I recently tried adding the following
lines to my
/etc/system file to force it to always connect at 100mps full duplex.
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
Then rebooted my system. it is now running like a snail.
Using ndd to read the parameters was interesting:
when I typed "/usr/sbin/ndd -get /dev/hme hme_adv_autoneg_cap"
I got an interesting answer......operation failed, Invalid argument.
It seems that the parameters are set and read a little differently than
those with the eri interface on the Sun Blades.
ndd -get /dev/hme adv_*** does seem to indicate that the values were set
appropriately;
however, ndd values obtained for link_speed and link_mode indicate I am
running
at 10 mps half-duplex.
I have removed these lines from my /etc/system file to get back where I was,
but can anybody see something I have done wrong or have suggestions how I
might correct the problem?
