There is an active switchport in 999 currently and 1001 before I 
switched to 999.  I don't know that the 4948 could be the problem 
though.  I've seen VLANs not come up until a port in the VLAN was active 
as well but that's normally on a switch or a router with a switchport 
(ISR w/ a Ethernet HWIC for example).  There isn't a mechanism to 
advertise VLANs or their local status across a trunk that I'm aware of 
(with VTP disabled at least).  VTP is transparent on the 4948 and not 
configurable on the 7206.  I should be able to configure a dozen 1Q 
sub-ints on a router's interface and have them be up/up regardless of 
whether it's configured for use on the connected switch.  At least I'm 
pretty sure I should be able to.

What silly thing am I missing?  Maybe it will come to me after consuming 
chips and salsa.  Thanks for the info
