DES-3500 Layer 2 Fast Ethernet Switch CLI Reference Manual
82
DES-3526:admin#
config stp instance_id
Purpose Used to add or delete an STP instance ID.
Syntax
config stp instance_id <value 1-4> [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 5 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 1-4> - Enter a number between 1 and 4 to define the
instance_id. The Switch supports 5 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:
DES-3526:admin#config stp instance_id 2 add_vlan 10
Command : config stp instance_id 2 add_vlan 10
Success.
DES-3526:admin#
Example usage:
To remove VID 10 from instance ID 2:
DES-3526:admin#config stp instance_id 2 remove_vlan 10
Command : config stp instance_id 2 remove_vlan 10
Success.
DES-3526:admin#
delete stp instance_id
Purpose Used to delete a STP instance ID from the Switch.
Syntax
delete stp instance_id <value 1-4>
