Chapter 3: Configuration

Advanced Settings

Edge Port BPDU Filtering: Control whether a port explicitly configured as Edge will transmit and receive BPDUs.

Edge Port BPDU Guard: Control whether a port explicitly configured as Edge will disable itself upon reception of a BPDU. The port will enter the error-disabled state, and will be removed from the active topology.

Port Error Recovery: Control whether a port in the error-disabled state automatically will be enabled after a certain time. If recovery is not enabled, ports have to be disabled and re-enabled for normal STP operation. The condition is also cleared by a system reboot.

Port Error Recovery Timeout: The time to pass before a port in the error-disabled state can be enabled. Valid values are between 30 and 86400 seconds (24 hours).

Buttons:

-Save: Click to save changes.

-Reset: Click to undo any changes made locally and revert to previously saved values.

3.4.2. MSTI Mapping

When you implement a Spanning Tree protocol on the switch, the CIST is not available for explicit mapping, because it receives the VLANs that are not explicitly mapped. For this reason, you need to set the list of VLANs mapped to the MSTI. The VLANs must be separated with a comma and/or a space. A VLAN can only be mapped to one MSTI. An unused MSTI should simply be left empty, (i.e. with no VLANs mapped to it.)

This section describes it allows the user to inspect the current STP MSTI bridge instance priority configurations, and possibly change them as well.

Web Interface

To configure the Spanning Tree MSTI Mapping parameters in the Web interface:

1.Click Configuration, Spanning Tree, MSTI Mapping.

2.Specify the configuration identification parameters in the field. Specify the VLANs Mapped blank field.

3.Click the Save button to save the setting.

4.To cancel the setting, click the Reset button to revert to previously saved values.
