DES-3526 / DES-3526DC Layer 2 Fast Ethernet Switch CLI Reference Manual
71
Example usage:
To configure STP with path cost 19, hellotime set to 5 seconds, migration enable, and state enable for ports 1-5 of
module 1.
DES-3526:4#config stp ports 1-5 externalCost 19 hellotime 5 migrate yes state enable
Command: config stp ports 1-5 externalCost 19 hellotime 5 migrate yes state enable
Success.
DES-3526:4#
create stp instance_id
Purpose
Used to create a STP instance ID for MSTP.
Syntax create stp instance_id <value 1-4>
Description
This command allows the user to create a STP instance ID for the
Multiple Spanning Tree Protocol. There are 5 STP instances on
the Switch (one internal CIST, unchangeable) and the user may
create up to 4 instance IDs for the Switch.
Parameters
<value 1-4> - Enter a value between 1 and 4 to identify the
Spanning Tree instance on the Switch.
Restrictions
Only administrator-level users can issue this command.
Example usage:
To create a spanning tree instance 2:
DES-3526:4#create stp instance_id 2
Command: create stp instance_id 2
Success.
DES-3526:4#
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.
