Hi - hoping someone can help me with the above, I know this has been
covered before ... many times. But I'm having problems doing this on the
server detailed below, the server is networked with other Sun Enterprise
450's connected using CISCO switches. The CISCO switches ports are all
forced to be 100MB/FDX. The server in question, a Sun Fire 480R boots
and sets the "ce0" interface to be 100MB/HDX by default and has auto
negotiate ON. I want this to be 100MB/FDX with auto negotiate OFF, as
the other servers and switches are.
Sun Fire 480R
5.9 Generic_112233-04
Link Autospeed Status Speed Mode Ethernet Address
----- --------- ------ ------ ----- ------------------
ce0 on Up 100 HDX
For several other servers, namely 3 x Sun Enterprise 450's I used:
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_100fdx_cap 1
ndd -set /dev/hme adv_autoneg_cap 0
And they worked perfectly fine, all reporting hme0 as 100MB/FDX auto
negotiate OFF.
But when I did this on the 480R using:
ndd -set /dev/ce instance 0
ndd -set /dev/ce adv_10hdx_cap 0
ndd -set /dev/ce adv_100fdx_cap 1
ndd -set /dev/ce adv_autoneg_cap 0
The results I got were:
Link Autospeed Status Speed Mode Ethernet Address
----- --------- ------ ------ ----- ------------------
ce0 on Down 1000 FDX
I tried to bring the interface UP with "ifconfig ce0 up" but that didn't
do anything. As downtime is limited to 15mins here and there I ended up
rebotting the server to get it back working.
Of course once I have this working then the "/etc/system" can be edited
to make this change survive reboots.
Any help / advice would be appreciated.
Thanks - Julian.
