Proper way to configure NIC in full duplex

[Lee Dilkie]

I believe that all your alias ip addresses should have a netmask of
0xffffffff. Only your first address is supposed to have the "true" netmask.
This is what the manual claims and what I've done.

Also, I have a realtek card with the rl driver and it's slow for me as well
but my research on the net seems to say this is just a cheap and slow card.

if you 'man ifconfig' and 'man rl' you can see the options you are allowed
to force.

Subject: Proper way to configure NIC in full duplex


Hello,

I'm using an r10 nic and have all the information already configured in
rc.conf, however, transfer speeds are unusually slow (i.e., 55-60kbps when
it SHOULD be somewhere near 1.00mbps+)

Someone told me that I might not be running the interface in full duplex.
How can I determine this?  How can I fix it if I am not currently running in
full duplex?

Any assistance is appreciated and below is the output of my interface
information:

www# ifconfig rl0
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
