Protocol Enabled (Spanning Tree); Protocol Type (Spanning Tree Protocol) - Huawei OptiX OSN 550 Configuration Manual

OptiX OSN 550 Multi-Service CPE Optical Transmission
System
Configuration Guide
Configuration Guidelines
If the bandwidth needs to be increased and several ports need to be enabled to share the service,
select the load sharing mode. If only one port needs to carry the service and protection is required
for this port, select the load non-sharing mode.

7.68 Protocol Enabled (Spanning Tree)

Description
Protocol Enabled (Spanning Tree) indicates whether the spanning tree protocol is enabled on
the VB.
Impact on the System
After the protocol is enabled, and when the computation of the spanning tree is performed
according to the protocol type (STP/RSTP), the network topology changes and services are
interrupted temporarily.
Values
Value Range
Enabled, Disabled
Configuration Guidelines
The user can set this parameter according to the actual service requirement.
Relationship with Other Parameters
This parameter can be set only when the VB is created and Protocol Type is selected.
Related Information
The rapid spanning tree protocol (RSTP) can realize all the functions of the spanning tree. Similar
to the STP, the RSTP avoids temporary loops. Different from the STP, the RSTP shortens the
time delay at the ports from blocking to forwarding, restores the network connectivity more
rapidly, and provides better services.

7.69 Protocol Type (Spanning Tree Protocol)

Description
Protocol Type (Spanning Tree) indicates that the Ethernet data board of the OptiX OSN
equipment supports two spanning tree protocols, that is, the spanning tree protocol (STP) and
the rapid spanning tree Protocol (RSTP).
