DGS3100#
config stp instance_id
Purpose To add or delete VLANs of STP instance ID.
Syntax
config stp instance_id <value 1-15> [add_vlan | remove_vlan]
<vidlist>
Description The config stp instance_id command maps VIDs (VLAN IDs) STP
instances on the Switch. A 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 (instance 0 – is 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 and the same name.
Parameters <value 1-15> - The value of the instance_id. The value may be
between 1 and 15. The Switch supports 16 STP regions with one
unchangeable default instance ID set as 0.
add_vlan – Indicates that VIDs specified in the <vidlist> parameter
are to be added to the STP instance_id.
remove_vlan – Indicates that VIDs specified in the <vidlist>
parameter are to be removed from the STP instance_id.
<vidlist> – Specifies the range of VIDs to add to or remove from the
STP instance_id. Supported VIDs on the Switch range from ID
number 1 to 4094. By default each created vlan belongs to instance
0.
Restrictions Only administrator or operator-level users can issue this command.
Example usage:
To configure instance id 2 to add VID 10:
