Parameters region-name - Enter a name for an MST region. A maximum of 32 characters. Default System MAC address Command Mode MULTIPLE-SPANNING-TREE Usage Information By default, the MST protocol assigns the system MAC address as the region name. Two MST devices within the same region must share the same region name, including matching case. Example OS10(conf-mst)# name my-mst-region Supported Releases 10.2.0E or later revision Configures a revision number for the MSTP configuration. Syntax revision number Parameters number - Enter a revision number for the MSTP configuration, from 0 to 65535. Default 0 Command Mode MULTIPLE-SPANNING-TREE Usage Information To have a bridge in the same MST region as another, the default values for the revision number must match on all Dell EMC hardware devices. If there are non-Dell EMC devices, ensure the revision number value matches on all the devices. For more information, see Non-Dell Hardware. Example OS10(conf-mst)# revision 10 Supported Releases 10.2.0E or later spanning-tree mst Configures an MST instance and determines root and bridge priorities. Syntax Parameters spanning-tree mst instance number priority | root {primary | secondary} • instance number - Enter an MST instance number, from 0 to 63. For Mt. Echo platform, enter a MST instance value from 0 to 61. • priority priority value - Set a bridge priority value in increments of 4096, from 0 to 61440. Valid priority values are: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344, and 61440. All other values are rejected. • root - Enter a primary or secondary root. • primary - Enter a device as a primary root. • secondary - Enter a device as a secondary root. Default Not configured Command Mode CONFIGURATION Usage Information The MSTP determines the root bridge but you can assign one bridge a lower priority to increase the probability it being the root bridge. A lower priority-value increases the probability of the bridge becoming a root bridge. The no version of this command resets the value to the default. Example OS10(config)# spanning-tree mst 0 priority 0 OS10(config)# spanning-tree mst 2 root primary Supported Releases 10.2.0E or later 450 Layer 2
