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]
<vidlist>
Description This command is used to map VIDs (VLAN IDs) to previously
configured STP instances on the Switch by creating an
instance_id. 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 (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> - 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:
To configure instance ID 2 to add VID 10:
DGS-3324SRi:4#config stp instance_id 2 add_vlan 10
Command : config stp instance_id 2 add_vlan 10
Success.
DGS-3324SRi:4#
Example usage:
To remove VID 10 from instance ID 2:
DGS-3324SRi:4#config stp instance_id 2 remove_vlan 10
Command : config stp instance_id 2 remove_vlan 10
Success.
