Or only have two vlan's per interface card. I also hacked together a weird patch to mutate the MAC address from the parent card, but that didn't help since the Cisco threw away too much info in the hash (apparently). I'm sure that I could have gotten that to work, but it was the wrong solution. Cisco opened a bug on it for PU, so there may be an option in newer CEF capable switches for how to deal with hash collisions. - Steve -- C.
