DES-3500 Layer 2 Fast Ethernet Switch CLI Reference Manual
77
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-3500:admin#config stp ports 1-5 externalCost 19 hellotime
1
migrate yes state
enable
Command: config stp ports 1-5 externalCost 19 hellotime
1
migrate yes state enable
Success.
DES-3500:admin#
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 and Operator-level users can issue this
command.
Example usage:
To create a spanning tree instance 2:
DES-3500:admin#create stp instance_id 2
Command: create stp instance_id 2
Success.
DES-3500: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
.
