Deployment Guide

To view the bridge priority, use the show config command from PROTOCOL MSTP mode.
Dell(conf-mstp)#msti 2 bridge-priority 0
Dell(conf-mstp)#show config
!
protocol spanning-tree mstp
MSTI 2 bridge-priority 0
Dell(conf-mstp)#
Interoperate with Non-Dell Networking OS Bridges
The 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 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
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
revision number
The range is from 0 to 65535.
The default is 0.
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
