DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Switch CLI Reference Manual
DES-3028P:4#config stp mst_config_id revision_level 10 name Trinity
Command : config stp mst_config_id revision_level 10 name Trinity
Success.
DES-3028P:4#
config stp mst_ports
Purpose Used to update the port configuration for a MSTP instance.
Syntax
config stp mst_ports <portlist> instance_id <value 0-4>
{internalCost [auto | <value 1-20000000>] priority <value 0-240>
Description 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
MAC address 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.
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 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, with instance id 2, to have an auto internalCost and a priority of 16:
DES-3028P:4#config stp mst_config_id ports 1-5 instance_id 2
internalCost auto priority 16
Command : config stp mst_config_id ports 1-5 instance_id 2
internalCost auto priority 16
Success.
