config stp instance_id
Used to add or delete an STP instance ID.
Purpose
config stp instance_id <value 1-4> [add_vlan | remove_vlan] <vidlist>
Syntax
This command is used to map VIDs (VLAN IDs) to previously configured STP instances on
Description
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
d efault entry). VIDs can belong to only one spanning tree instance at a time.
<value 1-4> - Enter a number between 1 and 4 to define the instance_id. The switch supports
Parameters
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.
Only administrator-level users can issue this command.
Restrictions
Example usage:
To configure instance id 2 to add VID 10:
DES-3550:4#config stp instance_id 2 add_vlan 10
Command : config stp instance_id 2 add_vlan 10
Success.
DES-3550:4#
Example usage:
To remove VID 10 from instance id 2:
DES-3550:4#config stp instance_id 2 remove_vlan 10
Command : config stp instance_id 2 remove_vlan 10
Success.
DES-3550:4#
DES-3550 Layer 2 Fast Ethernet Switch
Switches in the same spanning tree region having the same STP
NOTE:
instance_id must be mapped identically, and have the same configuration
revision_level number and the same name.
