I fully agree with last hergp comment. Ethernet settings should be set to auto negotiate. This should just work. If it doesn't, have the vendors fix their hardware instead of trying to mess with settings.
This is from experience. I have seen a lot of networking issues in various sites and plenty of them were due to wrong settings, the most common being one side auto-neg while the other one had fixed speed/duplex mode.
This is somewhat similar to IP settings. If you have a correctly configured dhcp server, things usually work fine. If you have fixed addresses and let people setting them, you quickly end up with duplicate IPs, wrong DNS settings, wrong default routers and so on.

Hi,
We have a 4 port Sun gigaswift NIC card on our sun fire server.
If the card is a physical one I know how to check the settings/speed. But since this is a virtual card with 4 ports , I am not sure as how we can check the settings.

wicd-manager-settings.conf
WICD-MANAGER-SETTINGS.CONF(5) File Formats Manual WICD-MANAGER-SETTINGS.CONF(5)
NAME
wicd-manager-settings.conf - contains settings that control Wicd's behavior
DESCRIPTION
This file contains general configuration information for Wicd.
This file is located at /etc/wicd/manager-settings.conf
SETTINGS
link_detect_tool = <0|1|2>
0 = autodetect
1 = ethtool
2 = mii-tool
flush_tool = <0|1|2>
0 = autodetect
1 = ip
2 = route
backend = <ioctl|external>
Default is ioctl backend.
signal_display_type = <0|1>
0 = Show signal strength as a percentage
1 = Show signal strength in dBm
dhcp_client = <0|1|2|3>
0 = autodetect
1 = dhclient
2 = dhcpcd
3 = pump
sudo_app = <0|1|2|3>
0 = autodetect
1 = gksu
2 = kdesu
3 = ktsuss
wired_interface = <interface_name>
always_show_wired_interface = <True|False>
wired_connect_mode = <0|1>
0 = connect to wired interface automatically
1 = do not connect to wired interface automatically
prefer_wired = <True|False>
True = Switch to wired interface if a link is detected, even if already connected to wireless
False = Do not switch to wired interface automatically
wireless_interface = <name_of_wireless_interface>
wpa_driver = <wext|madwifi|ndiswrapper|hostap|hermes|atmel|broadcom|ipw|ralinklegacy|none>
The default (and best supported) is wext. It should work properly in most cases. The none special value makes WICD pass no -D
parameter to wpa_supplicant, which might be useful in some cases.
auto_reconnect = <True|False>
This settings determines whether Wicd will attempt to reconnect on connection loss.
use_global_dns = <True|False>
If set to "True" and values are specified in the global DNS settings below, this will cause Wicd to use these DNS settings.
global_dns_dom = <plaintext_domain_name>
This specifies the default search domain to be used by the resolver.
global_dns_1 = <ip_address>
global_dns_2 = <ip_address>
global_dns_3 = <ip_address>
debug_mode = <integer_value>
0 = disabled
1 = enabled
