Configuring MSTP on the Switch

To configure and enable MSTP:

Create the MSTP region using the following command:
configure mstp region regionName
Create and configure the CIST, which forms the CST, using the following commands:
create stpd stpd_name {description stpd-description}

configure stpd stpd_name mode mstp cist

Note

You can configure the default STPD, S0 as the CIST.

No VLAN can be bound to the CIST and no ports can be added to the CIST. Therefore, the VLAN should be bound to the MSTI and the “show MSTI port” command will show the VLAN ports. The ports added to the MSTI are bound automatically to the CIST even though they are not added to it.
Enable the CIST using hte command:
enable stpd {stpd_name}
Create and configure MSTIs using the commands:
create stpd stpd_name {description stpd-description}

configure stpd stpd_name mode mstp cist instance
Add VLANs to the MSTIs using one of the following commands:
1. Manually binding ports
  configure stpd stpd_name add vlan vlan_name ports [all | port_list] {[dot1d | emistp | pvst-plus]}
  
  configure vlan vlan_name add ports [all | port_list] {tagged {} | untagged} stpd stpd_name {[dot1d | emistp | pvst-plus]}
2. Automatically binding ports to an STPD when ports are added to a member VLAN
  enable stpd stpd_name auto-bind vlan vlan_name
Enable the MSTIs using the command:.
enable stpd {stpd_name}
