config stp instance_id
Purpose
Used to add or delete VID to/from an STP instance.
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:
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 instances 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 and Power-User-level users can issue this command
Example usage:
To configure instance ID 2 to add VID 10:
DES-3528:admin# config stp instance_id 2 add_vlan 10
Command : config stp instance_id 2 add_vlan 10
Success.
DES-3528:admin#
Example usage:
To remove VID 10 from instance ID 2:
DES-3528:admin# config stp instance_id 2 remove_vlan 10
Command : config stp instance_id 2 remove_vlan 10
Success.
DES-3528:admin#
delete stp instance_id
Purpose
Used to delete a STP instance ID from the Switch.
Syntax delete stp instance_id <value 1-15>
Description
This command allows the user to delete a previously configured STP instance ID from the
Switch.
Parameters
<value 1-15> − Enter a value between 1 and 15 to identify the Spanning Tree instance on the
Switch.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command
Example usage:
To delete STP instance ID 2 from the Switch.
DES-3528:admin# delete stp instance_id 2
Command: delete stp instance_id 2
