I am a WAS admin performance tuning an AIX box. I used netstat -v to
browse network statistics.

One of the network cards has a tokenring adapter entry showing half
duplex.

IBM PCI Tokenring Adapter Specific Statistics:
---------------------------------------------------------
Media Speed Running: 16 Mbps Half Duplex
Media Speed Selected: 16 Mbps Full Duplex

Is this a problem?

What stats in the netstat report should I look at to determine whether
or not there are flow control issues?

Thanks in advance.

Patrick.

It'd be better to set the card to auto-negotiate if its possible.
Otherwise check with your network guys, they will advise on the correct
settings depending on the switch etc.
