MSTP VLAN Configuration Enhancement

C a u t i o n
When this software version is installed, the prior VLAN ID-to-MSTI mappings do not change. However,
this enhancement is not backward-compatible. If you install a software version prior to this version,
and you have configured MSTI entries instances mapped to VLANs, they will be removed from the
configuration file when booting to the prior version of software. You must remove all MSTP mappings
from the config file and then reconfigure the instance mapping after you are running the desired
software version.
If you want to save a copy of the switch configuration file to a tftp server before you install this
version, use this command:
ProCurve(config)# copy startup-config tftp <ip-address tftp server>
where <filename> is the name you choose for the pre-enhancement configuration file that you are
saving.
Overview
The MSTP VLAN configuration enhancement allows you to preconfigure an MSTP regional topology
and ensure that the same VLAN ID-to-MSTI assignments exist on each MSTP switch in the region.
The default behavior of the spanning-tree instance vlan command changes so that, before a static VLAN
is configured or a dynamic VLAN is learned on the switch, you can preconfigure its VLAN ID-to-MSTI
mapping. Later, when the VLAN is created, it is automatically assigned to the MSTI to which you had
previously mapped it.
By supporting preconfigured VLAN ID-to-MSTI topologies, the MSTP VLAN configuration enhance-
ment provides the following benefits:
Scalability: In a network design in which you plan to use a large number of VLANs, you can
■
preconfigure identical VLAN ID-to-MSTI mappings on all switches in a single, campus-wide MST
region, regardless of the specific VLANs that you later configure on each switch. After the initial
VLAN ID-to-MSTI mapping, you can decide on the exact VLANs that you need on each switch.
