Hello again,
Here is more information on the situation.
Packet Engines has not been very helpful (of course it IS Linux).
Good List.

same
> 2) Is the port enabled?
oh, yeah. ;*)
> 3) Is the port in the correct VLAN?
only one VLAN, and it is on it.
> 4) Is the port set to trunk? (if yes, then disable trunking)
disabled.
> 5) Is the port set to be the span port? (if yes, then disable span)
no spanning tree or span port.
> 6) Have you tried another port and patch leads?
yep.
> 7) What is the model number of the card in the Catalyst? And what version

Well, now this is the deal. We have ALOT of test equipment. :) I have no
physical access to these switches, or hubs, though, as that is a separate group.
It is a Catalyst 5500 with the IOS at some 11 rev or so. But no matter what, it
is not showing a link light at all.
So, we moved it to a Packet Engines' Hub (FDR12). This gets a link light at both
ends, but still no pingability. I actually see that there is no activity on the
back (there is a link light, a tx and an rx light) in the tx or rx.
I have now compiled in the yellowfin driver in my kernel, as when it did not
auto-insert into my modules list. I now see eth0 each time, with the correct IP,
subnet mask, broadcast, etc. via the /etc/sysconfig/network-scripts/ifcfg-eth0
and such.
So, now it loads on boot and the driver loads saying:
eth0: yellowfin type=ffffffffff at 0x1400 on IRQ 9 ff:ff:ff:ff:ff
Anyway, lsmod still shows not even one module loaded. Are there any prerequisite
modules?
netstat -nr shows all correct info for routing and such.
and ifconfig sees the card and has assigned the correct IP to it.
The most frustrating part is that the driver loads and the link light is up and
it is even hooked completely into Packet Engines' equipment (no cross-vendor
activity for now)
Any other advice or suggestions?
The idea of having to FORCE full-duplex is interesting. We have tried that, or
the net group claims that ALL ports are at full duplex. Is this an issue with
the PE Hubs also?
TIA
