I have a 3640 router setup with an ip address on the physical interface and
also an ip address on the subinterface. The physical interface is by
default vlan1 and the subinterfaces will be used for whatever other vlans I
have. I think it depends on the IOS version.
Thanks

If I remember correctly you cannot have an ip address on the actual
interface if you have sub-int's with ip's. That true?
