It seems at first glance your problem lies with the configuration of the interface or the switch the system is connected to. Having a lot of output packets is common in a server, I don't believe you have a problem there.




First you must find out what your NIC card is configured for or what your machine is set for in the /etc/system file there could be an entry that states something like the following:

set hme:hme_adv_100autoneg_cap=0
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0


These settings force the machine to be 100 fullduplex and does not allow the system to autonegotiate.

If these settings are not in the system file, then you can type the following commands to let you know what your system is configured for (you have to be root, and know what interface you are using hme0, le0, ge0)

[root@hostname]$ndd /dev/hme link_mode

[root@hostname]$ndd /dev/hme link_status

[root@hostname]$ndd /dev/hme link_speed

If your response is 1 to all, your machine is at 100fullduplex, if your response to any of these above commands is zero your machine is set to 100/halfduplex

Now that you have your NIC card settings, check with your IT department and find out what the switch is set for which this server is connected to. It looks like your machine is set to 100/full while the switch is set to 100/half. If this does not solve the problem take the machine down to the ok prompt. Run test-all. This runs a PROM level test which includes the NIC card.Or you can run post-results.

hme

HME(4)                                                     BSD Kernel Interfaces Manual                                                     HME(4)

NAME

     hme -- Sun Microelectronics STP2002-STQ Ethernet interfaces device driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device miibus
           device hme

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           if_hme_load="YES"

DESCRIPTION

     The hme driver supports Sun Microelectronics STP2002-STQ ``Happy Meal Ethernet'' Fast Ethernet interfaces.

     All controllers supported by the hme driver have TCP checksum offload capability for both receive and transmit, support for the reception and
     transmission of extended frames for vlan(4) and a 128-bit multicast hash filter.

HARDWARE

     The hme driver supports the on-board Ethernet interfaces of many Sun UltraSPARC workstation and server models.

     Cards supported by the hme driver include:

     o   Sun PCI SunSwift Adapter (``SUNW,hme'')
     o   Sun SBus SunSwift Adapter (``hme'' and ``SUNW,hme'')
     o   Sun PCI Sun100BaseT Adapter 2.0 (``SUNW,hme'')
     o   Sun SBus Sun100BaseT 2.0 (``SUNW,hme'')
     o   Sun PCI Quad FastEthernet Controller (``SUNW,qfe'')
     o   Sun SBus Quad FastEthernet Controller (``SUNW,qfe'')

NOTES

     On sparc64 the hme driver respects the local-mac-address? system configuration variable which can be set in the Open Firmware boot monitor
     using the setenv command or by eeprom(8).  If set to ``false'' (the default), the hme driver will use the system's default MAC address for
     all of its devices.  If set to ``true'', the unique MAC address of each interface is used if present rather than the system's default MAC
     address.

     Supported interfaces having their own MAC address include on-board versions on boards equipped with more than one Ethernet interface and all
     add-on cards except the single-port SBus versions.

HISTORY

     The hme driver first appeared in NetBSD 1.5.  The first FreeBSD version to include it was FreeBSD 5.0.

     The hme driver was written by Paul Kranenburg <pk@NetBSD.org>.
