nettl and io subsystems (How to find)

[Paul Thomson_2]

Could anyone tell me if there is a definitive guide as to what I should log / increase logging on in nettl to correspond with the particular lan card on a system.

For example.
# ioscan -fnuClan
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
lan 0 0/0/0/0 btlan3 CLAIMED INTERFACE HP PCI 10/100Base-TX Core

/dev/diag/lan0 /dev/ether0


# nettl -status

From the subsystems available in nettl, which should I use to check if my NIC is dropping packets ?

Is there say a guide to IO card / driver / nettl subsystem and perhaps a way to determine if a system is dropping excessive tcp packets.

When I use lanadmin / netstat -p / -s its not too revealling.

Thanks

You might try these two.

NS_LS_UDP ERROR DISASTER
NS_LS_IP ERROR DISASTER

You might also try this tool, its slightly easier to use.
