xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch Web UI Reference Guide create loops, however an edge port can lose edge port status if a topology change creates a potential for a loop. An edge port normally should not receive BPDU packets. If a BPDU packet is received, it automatically loses edge port status. Choosing the False parameter indicates that the port does not have edge port status. Alternatively, the Auto option is available. Restricted Role Use the drop-down menu to toggle Restricted Role between True and False. If set to True, the port will never be selected to be the Root port. The default is False.

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 the following window, click L2 Features > Spanning Tree > MST Configuration Identification, as show below: Figure 4-38 MST Configuration Identification window The fields that can be configured are described below: Parameter Description Configuration Name This name uniquely identifies the MSTI (Multiple Spanning Tree Instance). If a Configuration Name is not set, this field will show the MAC address to the device running MSTP. Revision Level (0-65535) This value, along with the Configuration Name, identifies the MSTP region configured on the Switch. MSTI ID (1-64) Enter a number between 1 and 64 to set a new MSTI on the Switch. Type This field allows the user to choose a desired method for altering the MSTI settings. The user has two choices: Add VID - Select this parameter to add VIDs to the MSTI ID, in conjunction with the VID List parameter. Remove VID - Select this parameter to remove VIDs from the MSTI ID, in conjunction with the VID List parameter. VID List (e.g.: 2-5, 10) This field is used to specify the VID range from configured VLANs set on the Switch. Supported VIDs on the Switch range from ID number 1 to 4094. Click the Apply button to accept the changes made for each individual section. Click the Edit button to re-configure the specific entry. Click the Delete button to remove the specific entry. 92
