Hi
Original question at bottom...
Most people said don't use auto-negotiation, it doesn't work.
Other responses;
Make sure if it's on, then it's on at only one end of the link
Make sure you have up to date patches on the Suns and Firmware in the Cat
switches
We went with not using autonegotiation and this works fine. The necessary
additions to /etc/system are;
ndd -set /dev/hme instance 0 (could be 1,2,3,....)
ndd -set /dev/hme adv_autoneg_cap 0
ndd -set /dev/hme adv_100T4_cap 0
ndd -set /dev/hme adv_100fdx_cap 1 # full duplex for 100mbit
ndd -set /dev/hme adv_100hdx_cap 0 # 100mbit half duplex off
ndd -set /dev/hme adv_10fdx_cap 0 # 10mbit full duplex off
ndd -set /dev/hme adv_10hdx_cap 0 # 10mbit half duplex off
there are other commands you can put in here but these are the most common ones.

Thanks to all of those who responded this is obviously something many people
have had to deal with.

Subject: hme, cisco and auto-negotiate
Hi
Can someone point me to some clear documentation regarding the best setup
for
Solaris 2.6, hme NICs from a variety sun h/w to CISCO C5500 switches for
auto-negotiate (one end/both ends/not at all) for UTP links.
We are seeing some NFS/NIS drop-out when we configure, for example auto 100.
Basically I'd like to get to the bottom of what's best, as we've had
conflicting
answers from various sources.
Sorry for the vague nature of the question :(
TIA, I will summarise.
