Interoperate with Non-Dell 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 is null.
•
Revision is a 2-byte number. The default revision number 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 the name and revision number must match on all Dell Networking OS devices. If there are
non-Dell devices that participate in MSTP, ensure these values match on all devices.
NOTE:
Some non-Dell devices 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
To change the region name or revision, use the following commands.
•
Change the region name.
PROTOCOL MSTP mode
name name
•
Change the region revision number.
PROTOCOL MSTP mode

Example of the name Command
To view the current region name and revision, use the show spanning-tree mst configuration
command from EXEC Privilege mode.
Dell(conf-mstp)#name my-mstp-region
Dell(conf-mstp)#exit
Dell(conf)#do show spanning-tree mst config
MST region name: my-mstp-region
