DES-3550 Layer 2 Fast Ethernet Switch
Used to create a STP instance ID for MSTP.
create stp instance_id <value 1-4>
This command allows the user to create a STP instance ID for the
Multiple Spanning Tree Protocol. There are 5 STP instances on
the Switch (one internal CIST, unchangeable) and the user may
create up to 4 instance IDs for the Switch.
<value 1-4> Enter a value between 1 and 4 to identify the
Spanning Tree instance on the Switch.
Only administrator-level users can issue this command.
