catalyst 3548 VLAN administratively down

i have catalyst 3548 switch
i want to do vlan and do routing between vlan

i created some vlan's and run command sh vlan int brief

it shows the default vlan is up, and the 2 new vlans status : administratively down

why is that?
what are the possibilities that i can do vlan routing from this switch, i have router 1701 if needed, but it has ethernet port, not fast ethernet
