Looks like you dont have any interfaces assigned to your VLAN 100.  You need to assign an interface to that VLAN before it will come up or add that VLAN to a trunk port.

Example:
interface ethernet 4/g22
switchport mode access
switchport access vlan 100
exit

See if that helps.  Also it looks like your using VLAN1 for all your interfaces by leaving them unconfigured.  VLAN1 has some limitations on it for security reasons such preventing VLAN hopping.  So its best not to use VLAN1 at all.  If your not using the port then leave it in VLAN1 if you are create a new VLAN enable it for routing then add that interface to the VLAN like in the example.

Thanks, your example helped out 100%.

Also, the links in your signature helped out even more.

The VLAN1 issue is huge for me; I have about 15 network switches I'll have to work it in over time.  I am starting that now.
