xStack DGS-3612G Layer 3 Gigabit Ethernet Managed Switch CLI Manual
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 4 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-3612G:4#create stp instance_id 2
Command: create stp instance_id 2
Success.
DGS-3612G: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
.
<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-level users can issue this command.
Example usage:
To configure instance ID 2 to add VID 10:
