DGS-3024 Layer 2 Switch CLI Reference Manual
config stp mst_config_id
Purpose Used to update the MSTP configuration identification.
Syntax
config stp mst_config_id {revision_level <int 0-65535> | name <string>
Description This command will uniquely identify the MSTP configuration currently
configured on the Switch. Information entered here will be attached to
BDPU packets as an identifier for the MSTP region to which it belongs.
Switches having the same revision_level and name will be considered as
part of the same MSTP region.
Parameters revision_level <int 0-65535> – Enter a number between 0 and 65535 to
identify the MSTP region. This value, along with the name will identify the
MSTP region configured on the Switch. The default setting is 0.
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.
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”:
DGS-3024:4#config stp mst_config_id revision_level 10 name Trinity
Command : config stp mst_config_id revision_level 10 name Trinity
Success.
DGS-3024:4#
config stp mst_ports
Purpose Used to update the port configuration for a MSTP instance.
Syntax
config stp mst_ports <portlist> instance_id <value 0-15>
{internalCost [auto | <value 1-20000000>] `priority <value 0-240>}
Description This command will update the port configuration for an 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.
Parameters <portlist> - Specify a port or range of ports to be configured.
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
an 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
