Actually, I was silly for not mentioning that in the original post, but
yes, it's up. I've even tried up/down/up on the card a few times after
fiddling with the driver knobs, but the same thing happened, no link on
the switch.
I've also tested this back-to-back with two machines and the same cards.
Same result: no transmission of data. Interestingly enough, the link
lite is lit on the cards (in back-to-back) and on the card but not the
switch. Not sure if that's significant or not. In the interest if
completeness, here's ifconfig output for that card:
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
ether 00:08:02:28:76:4d
inet 10.222.222.144 netmask 0xffffff00 broadcast 10.222.222.255
media: Ethernet 1000baseSX <full-duplex>
status: active
I also verified the MTU size to ensure the switch ports weren't
configured for jumbo frames. They are correctly set on the switch and on
the FreeBSD box, but no traffic flows.
