[Bioclusters] Re: Can't run full duplex on the xserve (fwd)

[Ruotti, Victor]

Andy:
It should work either way. One question, I am connection to a CISCO switch
which is set up to be in auto mode (full or half duplex). Do I have to force
the switch to go in full duplex for the Mac to follow?

Thanks,

Don't know if this is helpful or just plain stupid, but are the ifconfig
command options case-sensitive.

On my startup script (on a desktop, not an XServe) I have ...

ifconfig en0 media 100baseTX mediaopt full-duplex

(Note the capital 'T' in 100baseTX)

and it works for me.

Don't forget that it needs to go in the startup script or it will reset
every time you reboot.

One other thing, what network performance are you getting? Just that if your
XServe is half-duplex and the router is trying full-duplex then (in my
limited experience) everything will run grindingly slowly whereas if your
router is only doing half-duplex then there will be no problem (i.e. do both
ends think the connection is half-duplex, or just the XServe?)

Later,

Andy
