Interoperate with Non-Dell Networking OS Bridges
Dell Networking OS supports only one MSTP region.
A region is a combination of three unique qualities:
• Name is a mnemonic string you assign to the region. The default region name on Dell Networking OS
is null .
• Revision is a 2-byte number. The default revision number on Dell Networking OS is 0 .
• VLAN-to-instance mapping is the placement of a VLAN in an MSTI.
For a bridge to be in the same MSTP region as another, all three of these qualities must match exactly.
The default values for name and revision match on all Dell Networking OS equipment. If you have non-
Dell Networking OS equipment that participates in MSTP, ensure these values match on all the
equipment.
NOTE: Some non-Dell Networking OS equipment may implement a non-null default region name.
SFTOS, for example, uses the Bridge ID, while others may use a MAC address.
Changing the Region Name or Revision

• Change the region name.
