DES-3526 Layer 2 Fast Ethernet Switch
DES-3526:4#
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 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 5 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:
DES-3526:4#config stp instance_id 2 add_vlan 10
Command : config stp instance_id 2 add_vlan 10
Success.
DES-3526:4#
Example usage:
To remove VID 10 from instance id 2:
DES-3526:4#config stp instance_id 2 remove_vlan 10
Command : config stp instance_id 2 remove_vlan 10
