Question

how to make ndd mods permanent

Asked by: doubledrat

title says it all really.  I have a solaris box that's not negotiating the network settings correctly.  I've fixed it with ndd, but where do I put those changes so that they are efective on next reboot?

cheers

/etc/system
i.e.
set eri:eri_adv_autoneg_cap=0
set eri:eri_adv_100fdx_cap=0
set eri:eri_adv_100hdx_cap=0
set eri:eri_adv_10fdx_cap=1
set eri:eri_adv_10hdx_cap=0
set tcp:tcp_conn_hash_size=1024

 

by: doubledratPosted on 2003-08-18 at 07:11:38ID: 9173612

so I have to prefix the capabilities with eri_?  When I query the capabilities they just come back with e.g. auto_neg_cap, not eri_autoneg_cap

 

by: JustUNIXPosted on 2003-08-18 at 07:13:14ID: 9173621

Prefix the entries with your interface name (e.g. hme, qfe, le, eri, ge)
Could you post a "ifconfig -a" so I could post the complete entries?

Cheers

it's eri0.  it just seems a bit odd that what I have to put in /etc/system differs from the capabilities reported by the driver! my autoneg_cap isn't prefixed with adv either e.g.

Here's /etc/system entries for eri (setting 100 Mbit full duplex):

* Configuration of eri-parameters
  set eri:adv_autoneg_cap=0
  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

Simply prefix the "adv_*" capapbilities with eri: (as we want to set the
capapbilities for the eri driver). This is from you post above:
adv_autoneg_cap               (read and write)
adv_100T4_cap                 (read and write)
adv_100fdx_cap                (read and write)
adv_100hdx_cap                (read and write)
adv_10fdx_cap                 (read and write)
adv_10hdx_cap                 (read and write)

sorry to harp on, but I'd like to understand what's going on, so I can apply to future problems!

why am I using adv_ capabilities e.g. adv_autoneg_cap instead of autoneg_cap?  Both versions appear in the capabilities.

does adv stand for advanced?

ta

 

by: liddlerPosted on 2003-08-18 at 08:20:22ID: 9174148

I 'think' adv is advanced for the newer NICs like eri rather than the older NICs such as hme

 

by: JustUNIXPosted on 2003-08-19 at 01:07:59ID: 9179294

No, adv stands for "advertise". This means that the adapter/driver sends his
capabilites (advertises them)  to the other side. In this case the ethernet
adapter will tell the connected switch that he "can do" this mode.

The other variable "autoneg_cap" is the actual status (that's why it's read-
only). To be precise, each capabilty has THREE variables:
adv_<cap>           my system tells the other what he could
lp_adv_<cap>      the other system told me what it can (Link Partner)
<cap>                  the actual status of the capability on my system

Cheers

thanks.  that makes sense now.
