DGS-3024 Layer 2 Switch CLI Reference Manual

config stp instance_id

Purpose Used to add or delete an STP instance ID.

Syntax

config stp instance_id <value 1-15> [add_vlan | remove_vlan]

Description This command is used to map VIDs (VLAN IDs) to previously configured

STP instances on the Switch by creating an instance_id. An STP

instance may have multiple members with the same MSTP

configuration. There is no limit to the number of STP regions in a

network, but each region only supports a maximum of 16 spanning tree

instances (one unchangeable default entry). VIDs can belong to only

one spanning tree instance at a time.

Note that Switches in the same spanning tree region, having the same

STP instance_id, must be mapped identically and have the same

configuration revision_level number, as well as the same name.

Parameters <value 1-15> - Enter a number between 1 and 15 to define the

instance_id. The Switch supports 16 STP regions with one

unchangeable default instance ID set as 0.



add_vlan – Along with the vid_range <vidlist> parameter, this

command will add VIDs to the previously configured STP

instance_id.

remove_vlan – Along with the vid_range <vidlist> parameter,

this command will remove VIDs to the previously configured STP

instance_id.

<vidlist> – Specify the VID range from configured VLANs set on

the Switch. Supported VIDs on the Switch range from ID number 1

to 4094.

Restrictions Only administrator-level users can issue this command.

Example usage:

Example usage:

To remove VID 10 from instance ID 2:

DGS-3024:4#config stp instance_id 2 remove_vlan 10
