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.

       prtdscp [-v ] -s

DESCRIPTION

       prtdscp	displays  the  IP addresses associated with a Domain to Service Processor Communications Protocol (DSCP) link. If no arguments are
       specified, prtdscp displays the IP addresses on both ends of the DSCP link. The IP address of either the Service Processor or  domain  side
       can be displayed separately by the use of the -s or -d options, respectively.

OPTIONS

       The following options are supported:

       -v    Verbose mode. Print additional details about the program's internal progress to stderr.

       -h    Help. Print a brief synopsis of the program's usage and exit. All other command line arguments are ignored.

       -d    Display only the local domain's IP address.

       -s    Display only the remote Service Processor's IP address.

EXAMPLES

       Example 1 Displaying both addresses

       The following example displays both the local domain's IP address and the remote SP's IP address:

	 # prtdscp
	 Domain Address: 192.168.103.2
	 SP Address: 192.168.103.1

       Example 2 Displaying the local IP address

       The following example displays the local domain's IP address:

	 # prtdscp -d
	 192.168.103.2

       Example 3 Displaying the remote IP address

       The following example display the remote SP's IP address:

	 # prtdscp -s
	 192.168.103.1
