Table 4-9. MSTI Configuration screen options.
Label Description
Configuration Name The name which identifies the VLAN to MSTI mapping. Bridges must share the name and revision
(see below), as well as the VLAN-to-MSTI mapping configurations in order to share spanning trees for
MSTIs (intra-region). The name should not exceed 32 characters.
Configuration
Revision Revision of the MSTI configuration named above. This must be an integer between 0 and 65535.
MSTI The bridge instance. The CIST is not available for explicit mapping, as it will receive the VLANs not
explicitly mapped.
VLANS Mapped The list of VLANs mapped to the MSTI. The VLANs must be separated with commas and/or space. A
VLAN can only be mapped to one MSTI. An unused MSTI will be left empty (ex. without any mapped
VLANs).
