Configuring MSTP on the Switch
-
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 (Spanning Tree Domain),
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 (Multiple Spanning Tree Instances) 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:
-
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 {tag} | untagged} stpd stpd_name {[dot1d | emistp | pvst-plus]}
-
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}
