DES-3800:admin#
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
BPDU 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 or Operator-level users can issue this command.
Example usage:
To configure the MSTP region of the Switch with
revision_level
10 and the
name
“Trinity”:
DES-3800:admin#config stp mst_config_id revision_level 10
name Trinity
Command: config stp mst_config_id revision_level 10 name
Trinity
Success.
DES-3800:admin#
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 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 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.
