config stp priority
Purpose
update the STP instance configuration.
To
Syntax
config stp priority <value 0-61440> instance_id <value 0-15>
Description The
config stp priority
command updates the STP instance
configuration settings on the Switch. The MSTP uses the priority in
selecting the root bridge, root port and designated port. Assigning
higher priorities to STP regions instructs the Switch to give
precedence to the selected instance_id for forwarding packets. The
lower the priority value set, the higher the priority.
Parameters
priority <value 0-61440>
- The priority for a specified
instance_id
for
forwarding packets. The value may be between 0 and 61440, and
must be divisible by 4096. A lower value indicates a higher priority.
instance_id <value 0-15>
- The value of the previously configured
instance id for which the user wishes to set the priority value. An
instance_id of 0 denotes the default instance_id (CIST) internally set
on the Switch.
Restrictions Only
administrator-level users can issue this command.
Example usage:
To set the priority value for instance_id 2 as 4096:
DGS3100# config stp priority 4096 instance_id 2
Success.
DGS3100#
config stp mst_config_id
Purpose
To update the MSTP configuration identification.
Syntax
config stp mst_config_id {revision_level <int 0-65535> | name
<string>}
Description The
config stp mst_config_id
command uniquely identifies the
MSTP configuration currently configured on the Switch. Information
entered here is attached to BDPU packets as an identifier for the
MSTP region to which it belongs. Switches having the same
revision_level and name are considered to be part of the same
MSTP region.
Parameters
revision_level <int 0-65535>
– The MSTP region id number. The
value may be between 0 and 65535. This value, along with the
name, identifies the MSTP region configured on the Switch. The
default setting is 0.
name <string>
- A string of up to 32 alphanumeric characters to
uniquely identify the MSTP region on the Switch. This name, along
with the revision_level value identifies the MSTP region configured
on the Switch. If no name is entered, the default name is the MAC
address of the device.
Restrictions Only
administrator-level users can issue this command.
Example usage:
To configure the MSTP region of the Switch with revision_level 10 and the name “Trinity”:
