Adding a Port-Specific Multiple Spanning Tree Instance

To add a Multiple Spanning Tree Instance (MSTI) for a switched Ethernet port or an Ethernet trunk interface, do
the following:
NOTE
RUGGEDCOM ROX II supports up to 16 MSTIs per port/interface.
1. Make sure the CLI is in Configuration mode.
IMPORTANT!
Since each MSTI acts as an independent RSTP instance, its configuration is similar to that of
RSTP. However, until one or more VLANs are mapped to an MSTI, an MSTI is considered to be
inactive.
2. Add the MSTI by typing:
• For switched Ethernet ports:
interface switch slot port spanning-tree msti id
Where:
▪ slot is the name of the module location
▪ port is the port number (or a list of ports, if aggregated in a port trunk) for the module
▪ id is the ID for the Multiple Spanning Tree Instance
• For Ethernet trunk interfaces:
interface trunks id spanning-tree msti mstp-id
Where:
▪ id is the ID given to the interface
▪ mstp-id is the ID for the Multiple Spanning Tree Instance
