DGS–3426:5#create stp instance_id 2
Command: create stp instance_id 2
Success.
DGS–3426:5#
config stp instance_id
Purpose Used to add or delete vlans for 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 and Operator-level users can issue this command.
Example usage:
To configure instance ID 2 to add VID 10:
DGS–3426:5#config stp instance_id 2 add_vlan 10
Command : config stp instance_id 2 add_vlan 10
Success.
DGS–3426:5#
Example usage:
To remove VID 10 from instance ID 2:
DGS–3426:5#config stp instance_id 2 remove_vlan 10
Command : config stp instance_id 2 remove_vlan 10
Success.
