xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual
290
To create a spanning tree instance 2:
DES-3800:admin#create stp instance_id 2
Command: create stp instance_id 2
Success.
DES-3800: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 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 1-4>
- Enter a number between 1 and 4 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 or Operator-level users can issue this command.
Example usage:
To configure instance ID 2 to add VID 10:
DES-3800:admin#config stp instance_id 2 add_vlan
10
Command : config stp instance_id 2 add_vlan 10
Success.
DES-3800:admin#
Example usage:
To remove VID 10 from instance ID 2:
DES-3800:admin#config stp instance_id 2
remove_vlan 10
Command : config stp instance_id 2 remove_vlan
10
