To Save Current Configuration - HP ProCurve J8766A Release Note

You must map a least one VLAN ID to an MSTI when you create it. You cannot map a VLAN ID
to more than one instance. You can create up to 16 MSTIs in a region.
The no form of the spanning-tree instance vlan command removes one or more VLANs from
■
the specified MSTI. If no VLANs are specified, the no form of the command deletes the
specified MSTI.
When you remove a VLAN from and MSTI, the VLAN returns to the IST instance, where it can
remain or be re-assigned to another MSTI configured in the region.
If you enter the spanning-tree instance vlan command before a static or dynamic VLAN is
■
configured on the switch to preconfigure VLAN ID-to-MSTI mappings, no error message is
displayed. Later, each newly configured VLAN that has already been associated with an MSTI
is automatically assigned to the MSTI.
This new default behavior differs from automatically including configured (static and dynamic)
VLANs in the IST instance and requiring you to manually assign individual static VLANs to an
MSTI.
The valid VLAN IDs that you can map to a specified MSTI are from 1 to 4094. The VLAN ID-
■
to-MSTI mapping does not require a VLAN to be already configured on the switch. The MSTP
VLAN enhancement allows you to preconfigure MSTP topologies before the VLAN IDs
associated with each instance exist on a switch.
■ When you use preconfigured VLAN ID-to-MSTI topologies, ensure that MSTP switches
remain in the same region by mapping all VLAN IDs used in the region to the same MSTIs on
each regional switch.
■ When you upgrade switch software to release K.13.XX and later, the existing MSTP topology
configuration is automatically saved. All existing VLAN ID-to-MSTI assignments are main-
tained on a switch for uninterrupted MSTP network operation.
