DGS-3600:4#config stp ports 1:1-1:5 externalCost 19 hellotime 5
migrate yes state enable
Command: config stp ports 1:1-1:5 externalCost 19 hellotime 5
migrate yes state enable
Success.
DGS-3600:4#
create stp instance_id
Purpose Used to create a STP instance ID for MSTP.
Syntax
create stp instance_id <value 1-15>
Description This command allows the user to create a STP instance ID for the
Multiple Spanning Tree Protocol. There are 16 STP instances on the
Switch (one internal CIST, unchangeable) and the user may create up
to four instance IDs for 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-level users can issue this command.
Example usage:
To create a spanning tree instance 2:
DGS-3600:4#create stp instance_id 2
Command: create stp instance_id 2
Success.
DGS-3600:4#
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.
