Solaris 8 says: Link down, Cable Problem ? 2

[irshad]

I have these on my home LAN:

1. Sun Ultra 5 Solaris 8
2. Win 2000 PC
3. Win NT laptop

They are all hooked into a LinkSys Router.
The Router is hooked into my Motorala Cable Modem.

Here's the problem:
The PC and the laptop can see each other on the LAN.
The Solaris 8 is only visible on the Lan INTERMITTENTLY.

The lights on the Router for the PC and laptop are always ON.
When I reboot the Solaris box, the lights on the Router sometimes come ON, and sometimes they stay OFF. When they stay OFF, I see the message: "Link down, Cable Problem?" during reboot.

I have tried different cables, and tried various combinations of the 4 avalable ports on the back of my Router.

If I plug in the Sun box DIRECTLY into my cable modem, then I don't see the above message. (but then I don't have a LAN anymore)

Please help, I've been struggling with this for a while now.

Thanks,
Irshad Ahmed (I am relatively new to Sun)

Irshad,

Is the sparc still only visible intermittently if you unplug the cable modem from the router?

Hi Mike,

If I unplug the cable modem from the router, then there is no concept of "visibility", right? The Solaris box becomes a stand-alone box, and it is cut off from the LAN.

Then, I can only log on to it from the console.

It seems to be a problem with sun interface parameters (Link speed, Link type, etc),check with "ndd", if both interfaces and have same speed and same duplex mode...if is okay try disable auto_configuration for sun interface and force 100/half-duplex or 10/half-duplex.

Regards,

CA.

Modifications might need to be made in the /etc/system file.
(hme settings)

PROBLEM FIXED !!

Thank you all for the information.
I fixed the problem by adding the following lines to my /etc/system and then rebooting:

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

Thank you all very much,
Irshad Ahmed
