First thanks to Andrew Williams, Russell Page,
Hendrik Visage for there most appreciated suggestions.
I kind off used all there suggestions.
I ended up setting auto-negotiate on v440 system and
no-autonegotiate on v480R. I found that if both are
hard wired to 1000Mbps and we bring down and back up
one interface card, the link won't come up. One of the
members suggested that v480 has problems when
interface parameters are set using ndd. So I set
interface parameters on v480 by editing the ce device
driver configuration file, ce.conf. Thanks to Andrew's
documentation which made this task very simple.
---------------------------------------------------------
Editing ce.conf
Configuring ce.conf
1) Determine the names:
$ grep ce /etc/path_to_inst
"/pci@9,700000/network@2" 0 "ce"
"/pci@9,600000/network@1" 1 "ce"
When configuring for ce0 use line 1. In this case the
parent name is: /pci@9,700000 In the case of a ce
device the tree name is pci108e,abba by
definition(sun document: 816-3330.pdf, pg. 81). As for
the unit name in this case it is 2 from the first line
network@2.
2) Construct ce.conf
$ cd /platform/sun4u/kernel/drv
$ vi ce.conf
Enter the following line (as a single line):
name="pci108e,abba" parent="/pci@9,700000"
unit-address="2" adv_autoneg_cap=0 adv_10hdx_cap=0
adv_10fdx_cap=0 adv_100hdx_cap=0 adv_100fdx_cap=1
adv_1000hdx_cap=0 adv_1000fdx_cap=0 adv_100T4_cap=0;
This will set the system too 100 fdx mode just move
the 1 around to specify the correct operating mode.
3) Reboot the system.
4) Check the /var/adm/messages file to see the
connection speed.
Problems:
If there is a message in the /var/adm/messages file
which says something like:
WARNING: ce@2: ce.conf properties not merged
This means that the values containned in ce.conf are
wrong in someway.
-check the parent name (/pci@9,700000")
-check the unit-address

Original question with responses from Hendrik:
Hello Gurus,
> We have a 100Mbps network and have
v440,v480
systems with two NICs on each which can support
1000Mbps .We only use one NIC
on each system to connect to network. I thought of
using the additional
NIC card of each system to be connected directly using
crossover so
that we get 1000Mbps between appserver and database
server. I was
successfully able to do this but wanted to get this
verified. I am getting a
speed of 19MBytes/sec over this link using ftp.
At least it's twice as fast as 100Mbps ethernet ;^)
> I used a different subnet addresses for crossover
connection to
prevent any confusion.
Which was to be the expected :)
> Here are the routing table of one system. Both are
same except for IP
addresses(.50,.51). Ce1 is the Gig crossover link.
10.50.5.254 is our
network gateway entry /etc/defaultrouter.

Why? It's already on the same network?
Rather check the ARPs with "arp"
then if it's there, use snoop -d ce1 to see what's not
going over that
link.
Also check dmesg etc. for link status.
