OK, I ask this question last week, and have made progress.....
I have a 6509 with SUP2 MSFC2
48 port line card.
I can't get Clients directly connected in 2 seperate VLANs to communicate.
NOW READ THIS CAREFULLY !!!!
I have a concurrent project going and I upgraded the SUP2s to Native IOS, and while doing that Upgraded my SUP2 as well.
IN that chasis, my card routes perfectly.
Move the cards back to the original 6509 chasis and host a on vlan 2 cannot ping host b on vlan 3.
Put the cards back in the other Chasis works great.
Both Chasis seem to be the same, Power supples don't complain.
It there a backplane jumper anything that could be missing?
AGAIN READ the QESTION before you ask for configs....
