How to disable ce Ethernet autonegotiation for boot net

Turning autonegotiation off and setting speed/mode manually is called “forced mode”. For the Sun[TM] GigaSwift on-board interfaces and Network Interface Cards (ce), and for bge on-board interfaces, boot in “forced mode” is possible.; M! c  u9 {5 l5 @

2 l9 A! n  R4 d) e

In jumpstart “boot net”, 3 steps are involved. The driver must be forced in all 3 steps of the jumpstart boot process.4 C5 F& z” u; C& x

 

1) Force the interface on the client’s boot PROM:% t% f4 C( e  i* f

 

ok boot /pci@1f,2000/pci@1/network@0:speed=100,duplex=full,2 |7 E! [! {0 i/ T! Q

or1 W) n8 O+ c) I+ m7 w& m

ok devalias net /pci@1f,2000/pci@1/network@0:speed=100,duplex=full,. m’ m2 h; U& v

ok boot net

 

(To make this change persistent against OBP reset, use nvalias instead of devalias.)

 

2) inetboot is loaded from the boot server:

1 c# R% V% O, q+ R% ^” n. ^& h

An inetboot file which honours the “forced” ce setting is needed on the boot server.

This is included in Solaris 8 Patch 111306-05; for Solaris 9, it is Patch 113578-01.; K: E: M” P’ h, W: i. c% S7 }

These patches must be applied on the boot server.

3) Client uses the OS from the filesystem of the boot server:

On the boot server, create a

../Boot/platform/sun4u/kernel/drv/ce.conf

(the same directory in which the ce 32 bit driver is located, one single line, example for 100 FDX):; [8 G) f9 s( [  r, ]

adv_100hdx_cap=0 adv_10fdx_cap=0 adv_10hdx_cap=0;

 

Note: With some switches, adv_autoneg_cap=0 results in Link Down.

Use adv_autoneg_cap=1 in this case (Autonegotiation enabled, Fixed Speed/Duplex)
