Thanks guys, that's really helpful. Do you have any information on how
many subinterfaces the 6500/SUP2 will support? I found another thread on
this mailing list where someone was saying that you can't re-use VLAN IDs,
even when using subints.

Eg. If I have Gi2/1.300 with encapsulation dot1Q 300, I can't have Gi2/2
with encapsulation dot1Q 300. Is that right?

Thanks,
Andrew
