config stp ports
p2p [true | false | auto] – true indicates a point-to-point (P2P)
shared link. P2P ports are similar to edge ports however they are
restricted in that a P2P port must operate in full-duplex. Like edge
ports, P2P ports transition to a forwarding state rapidly thus
benefiting from RSTP. A p2p value of false indicates that the port
cannot have p2p status. auto allows the port to have p2p status
whenever possible and operate as if the p2p status were true. If
the port cannot maintain this status (for example if the port is
forced to half-duplex operation) the p2p status changes to operate
as if the p2p value were false. The default setting for this
parameter is auto.
state [enable | disable] − Allows STP to be enabled or disabled for
the ports specified in the port list. The default is enable.
Restrictions Only administrator-level users can issue this command.
Example usage:
To configure STP with path cost 19, hellotime set to 5 seconds, migration enable, and state enable for ports 1-5 of
module 1.
DGS-3324SRi:4#config stp ports 1:1-1:5 externalCost 19 hellotime
5 migrate yes state enable
Command: config stp ports 1:1-1:5 externalCost 19 hellotime 5
migrate yes state enable
Success.
DGS-3324SRi:4#
create stp instance_id
Purpose Used to create a STP instance ID for MSTP.
Syntax
create stp instance_id <value 1-15>
Description This command allows the user to create a STP instance ID for the
Multiple Spanning Tree Protocol. There are 16 STP instances on
the Switch (one internal CIST, unchangeable) and the user may
create up to 15 instance IDs for the Switch.
Parameters <value 1-15> - Enter a value between 1 and 15 to identify the
Spanning Tree instance on the Switch.
Restrictions Only administrator-level users can issue this command.
Example usage:
To create a spanning tree instance 2:
DGS-3324SRi:4#create stp instance_id 2
Command: create stp instance_id 2
Success.
