I've found that if you manually configure your (the pfsense) interface
connnected to a cisco switch to full duplex, the cisco will adjust. For
whatever reason, cisco switches tend to default to half duplex during
the negotiation. Go figure.

I've seen this a few times on Cisco switches; telnet to the switch
and look at the interface that is connected to the pfSense box (show
int fastethernet 0/#) and see if it is running at full or half
duplex. If it's half, then manually set the interface to full duplex
with the following commands...
conf t
int fastethernet 0/$
duplex full
speed 100
You may need to power cycle the pfSense box but it should fix the
issue. Ensure that you save the config on the Cisco switch with
write memory.
Sorry for the simplicty, I don't know what level of Cisco you are...
I would have been ok, I guess, but the switch is the ISP's so they'll
have to check.
Thanks,
