Hello PDUs are only sent on the specified level for the selected VLANs. This can be useful for level 1/level 2 routers that are neighbors.
Note that for per-level VLAN configurable parameters L1 and L1/L2, point-to-point interfaces use the level 1 parameters, and L2-only point-to-point interfaces use the L2 parameters.
The following command configures all IS-IS VLANs to use circuit type level 1:
configure isis vlan all circuit-type level 1
