config stp mst_ports

 

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.

Parameters

<portlist> - Specifies a port or range of ports to be configured. The

 

port list is specified by listing the lowest slot number and the

 

beginning port number on that slot, separated by a colon. Then

 

the highest slot number, and the highest port number of the range

 

(also separated by a colon) are specified. The beginning and end

 

of the port list range are separated by a dash. For example, 1:3

 

specifies slot number 1, port 3. 2:4 specifies slot number 2, port

 

4. 1:3-2:4 specifies all of the ports between slot 1, port 3 and slot

 

2, port 4 in numerical order.

 

instance_id <value 0-15> - Enter a numerical value between 0 and

 

15 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 internalCost represents a quicker

 

transmission.

 

priority <value 0-240>- Enter a value between 0 and 240 to set

 

the priority for the port interface. A higher priority will designate the

 

interface to forward packets first. A lower number denotes a

 

higher priority.

Restrictions

Only administrator-level users can issue this command.

 

 

Example usage:

To designate ports 1 through 5 on module one, with instance ID 2, to have an auto internalCost and a priority of 16:

DES-6500:4#config stp mst_config_id ports 1:1-1:5 instance_id 2 internalCost auto priority 16

Command : config stp mst_config_id ports 1:1-1:5 instance_id 2 internalCost auto priority 16

Success.
