[ Switching > L2-Redundancy > Spanning Tree > Port ]
In this dialog, you activate the Spanning Tree function on the ports, specify edge ports, and specify
the settings for various protection functions.
The dialog contains the following tabs:

[CIST]

[Guards]
[ CIST ]
In this tab, you have the option to activate the Spanning Tree function on the ports individually,
specify the settings for edge ports, and view the current values. The abbreviation CIST stands for
Common and Internal Spanning Tree.
Note: Deactivate the
Spanning Tree
function on the ports that are participating in other Layer 2
redundancy protocols. Otherwise, it is possible that the redundancy protocols operate differently
than intended. This can cause loops.
