xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
config stp ports
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.
lbd [enable | disable] – When this is enabled, the Switch will temporarily block
STP on the port when a BDPU packet has been looped back. If the Switch
detects its own BDPU packet coming back, it signifies a loop on the network.
STP will automatically be blocked and an alert will be sent to the
administrator. The default is disable.
fbpdu [enable | disable] – Enabling this parameter will allow the forwarding of
STP BPDU from other network devices when STP is disabled on the port.
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-3400:4#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-3400:4#
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-3400:4#create stp instance_id 2
Command: create stp instance_id 2
Success.
