xStack Gigabit Layer 3 Switch Command Line Interface Manual
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.
