DES-1228/ME Layer 2 Metro Ethernet Switch CLI Reference Manual
Used to create a STP instance ID for MSTP.
create stp instance_id <value 1-8>
This command allows the user to create a STP instance ID for the Multiple Spanning Tree
Protocol. There are 9 STP instances on the Switch (one internal CIST, unchangeable) and
the user may create up to 8 instance IDs for the Switch.
<value 1-8> − Enter a value between 1 and 8 to identify the Spanning Tree instance on the
Switch.
Only Administrator-level users can issue this command.
Used to add or delete an STP instance ID.
config stp instance_id <value 1-8> [add_vlan | remove_vlan] <vidlist>
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 9 spanning tree instances (one unchangeable
default entry). VIDs can belong to only one spanning tree instance at a time.
NOTE:
instance_id must be mapped identically, and have the same configuration
revision_level number and the same name.
<value 1-8> − Enter a number between 1 and 8 to define the instance_id. The Switch
supports 9 STP instances 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.
Switches in the same spanning tree region having the same STP
