config stp mst_config_id
Restrictions
Example usage:
To configure the MSTP region of the Switch with revision_level 10 and the name "Trinity":
DES-3800:4#config stp mst_config_id revision_level 10 name Trinity
Command : config stp mst_config_id revision_level 10 name Trinity
Success.
DES-3800:4#
config stp mst_ports
Purpose
Syntax
Description
Parameters
name <string> - Enter an alphanumeric string of up to 32
characters to uniquely identify the MSTP region on the Switch.
This name, along with the revision_level value will identify the
MSTP region configured on the Switch. If no name is entered, the
default name will be the MAC address of the device.
Only administrator-level users can issue this command.
Used to update the port configuration for a MSTP instance.
config stp mst_ports <portlist> instance_id <value 0-15>
{internalCost [auto | <value 1-20000000>] `priority <value 0-
240>}
This command will update the port configuration for a STP
instance_id. If a loop occurs, the MSTP function will use the port
priority to select an interface to put into the forwarding state. Set a
higher priority value for interfaces to be selected for forwarding
first. In instances where the priority value is identical, the MSTP
function will implement the lowest port number into the forwarding
state and other interfaces will be blocked. Remember that lower
priority values mean higher priorities for forwarding packets.
<portlist> - Specifies a range of ports to be configured. The
beginning and end of the port list range are separated by a dash.
For example, 1-4 specifies all of the ports between port 1 and port
4.
instance_id <value 0-4> - Enter a numerical value between 0 and
4 to identify the instance_id previously configured on the Switch.
An entry of 0 will denote the CIST (Common and Internal
Spanning Tree.
internalCost – This parameter is set to represent the relative cost
of forwarding packets to specified ports when an interface is
selected within a STP instance. The default setting is auto. There
are two options:
auto – Selecting this parameter for the internalCost will set
quickest route automatically and optimally for an interface.
The default value is derived from the media speed of the
interface.
value 1-2000000 – Selecting this parameter with a value in the
range of 1-2000000 will set the quickest route when a loop
occurs. A lower
transmission.
