pooplex, more like

Posted by Dick on April 16, 2007

Just a quick ‘note to self’.

I noticed my NIC ( iprb0 ) is running in half duplex mode (autoneg doesn’t work with our switches):

vera # kstat iprb:0|grep duplex
   duplex                          half

A google finds very out of date information. I finally found the answer in the manpage, of all places

man iprb(4) says you need to edit /kernel/drv/iprb.conf

and set ForceSpeedDuplex to ‘4’ (for 100Mbit full dup):

vera # echo 'ForceSpeedDuplex=4;' > /kernel/drv/iprb.conf

(if you have more than 1 iprb NIC, you’ll have to set them all – see the manpage for details)

Then do a reconfigure reboot:

vera # reboot -- -r

after the reboot:

vera # kstat iprb:0|grep duplex
   duplex                          full
