What is the difference between the two commands?
Show run vlan # = blank output
show run int vlan # = vlan configuration
Likewise:

No virutal LANs configured
show vlan
A bunch of output displaying interfaces and their respective vlans.

The "show run int" shows the portion of the configuration in NVRAM that defines the actual interface. The second command (sh vlan) actually shows the live state of the VLAN's (nb - sh vlan id xxx for a single VLAN ID, if platform supports it) as actively kept in switch's database. One command shows the actual configuration, the other a portion of the running state.
