OS10 Enterprise Edition User Guide Release 10.4.0E(R3)


Non-Dell hardware

OS10 supports only one MST region. For a bridge to be in the same MST region as another, the three unique attributes (name, revision, and VLAN-to-instance-mapping) must match. The default values for name and revision number match on all Dell hardware. If you have non-Dell hardware that participates in MST, ensure these values match on all devices.

A region is a combination of three unique attributes:
  • Name — A mnemonic string you assign to the region (default is the system MAC address).
  • Revision — A 2-byte number (default is 0).
  • VLAN-to-instance mapping — Placement of a VLAN in an MSTI.
