[AG-TECH] Multicast dependent on NIC?

While trying to diagnose some multicast connectivity issues, much board
swapping has led us to suspect that some of the intermittence is due to
the card itself and/or its driver. Using the beacon server display at
http://beacon.dast.nlanr.net as some sort of reference, all except one
of our machines using Intel gigabit chip (PCI card or built-in) show up
with red squares & loss of 40-60%. A change to a card with Broadcom
chip eliminates problem completely - all squares go green.
At the moment the display at http://beacon.dast.nlanr.net shows about
half the beacon clients as having multiple red squares with 40-60%
loss. According to my theory, these machines are using Linux with Intel
Are any beacon users able to check this?
