MST Configuration Identification
The following windows in the MST Configuration Identification section allow the user to configure a MSTI instance on
the Switch. These settings will uniquely identify a multiple spanning tree instance set on the Switch. The Switch
initially possesses one CIST or Common Internal Spanning Tree of which the user may modify the parameters for but
cannot change the MSTI ID for, and cannot be deleted.
To view this window, click L2 Features > Spanning Tree > MST Configuration Identification:

tings window.
