Layer 2 DCN Management

You can enable or disable the Rapid Spanning Tree Protocol (RSTP) for an NE in the L2DCN Management window on the U2000 Web LCT. The RSTP protocol helps clear broadcast loops on a network.

Navigation Path

In the NE Explorer, select the NE and choose Communication > L2DCN Management from the Function Tree.

Parameters

Field	Value	Description
Configuration Status	Auto, Disabled	Specifies whether to enable the RSTP protocol. NOTE: It is recommended that the RSTP protocol uses its default enable/disable mode Auto for the NE level. That is, the RSTP protocol is automatically enabled/disabled depending on the enable/disable status of the L2 DCN function over IF ports.
Real Status	Enabled, Disabled	Indicates the actual status of the RSTP protocol. Real Status is queried to be Disabled in the following scenarios: Config Status is set to Disabled. When Config Status is set to Auto, the L2 DCN function is disabled for all IF ports on the NE. When Config Status is set to Auto, the L2 DCN function is enabled for at least one IF port on the NE. In this case, the RSTP protocol will automatically work. At this time, the queried Real Status is Enabled.
