Subject: Bad auto-negotiate on network adapter ...

For some reason, my 10/100 Mbps Ethernet adapter has "auto-
negotiated" to 100 HALF, which is causing lots of problems.

$ lsattr -El ent0 | grep media_speed
media_speed Auto_Negotiation Media
Speed True


$ entstat -d ent0 | egrep 'Errors|Speed'
Transmit Errors: 2345374 Receive Errors: 0
No Carrier Sense: 14 CRC Errors: 0

Late Collision Errors: 2344978 Receive Collision

Timeout Errors: 0 Packets Discarded by

No mbuf Errors: 0
Media Speed Selected: Auto negotiation
Media Speed Running: 100 Mbps Half Duplex

The switch side is set to auto; this hasn't been a problem for my
other systems (AIX and Solaris.)

Can I force the card to re-negotiate by doing an ...

ifconfig en0 down ; ifconfig en0 up

... or is there something else I can do to get it to re-negotiate
(short of rebooting)?

Thanks,
