DES-1228/ME Layer 2 Metro Ethernet Switch CLI Reference Manual
81
Example usage:
To configure STP with path cost auto, hellotime set to 2 seconds, migration enable, and state enable for ports 1-2 of
module 1.
DES-1228/ME:4#config stp ports 1-2 externalCost auto hellotime 2 migrate yes state
enable
Command: config stp ports 1-2 externalCost auto hellotime 2 migrate yes state en

DES-1228/ME:4#
create stp instance_id
Purpose
Used to create a STP instance ID for MSTP.
Syntax
create stp instance_id <value 1-8>
Description
This command allows the user to create a STP instance ID for the Multiple Spanning Tree
Protocol. There are 9 STP instances on the Switch (one internal CIST, unchangeable) and
the user may create up to 8 instance IDs for the Switch.
Parameters
<value 1-8>
−
Enter a value between 1 and 8 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-1228/ME:4#create stp instance_id 2
Command: create stp instance_id 2
Success.
DES-1228/ME:4#
config stp instance_id
Purpose
Used to add or delete an STP instance ID.
Syntax
config stp instance_id <value 1-8> [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 9 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 1-8>
−
Enter a number between 1 and 8 to define the
instance_id
. The Switch
supports 9 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.
