Configuring the MSTP Protocol Packet Format on an Interface
MSTP protocol packets can be transmitted in auto, dot1s, or legacy mode. The default mode is auto.
Context
MSTP protocol packets have two formats: dot1s (IEEE 802.1s standard packets) and legacy (proprietary protocol packets). The auto mode is introduced to allow an interface to automatically use the format of MSTP protocol packets sent from the remote interface. In this manner, the two interfaces use the same MSTP protocol packet format.
Do as follows on a device in a Multiple Spanning Tree (MST) region:
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The view of the Ethernet interface participating in STP calculation is displayed.
The following configuration can be configured both on a Layer 2 interface and a Layer 3 interface.
- (Optional) Run stp binding process process-id
The interface is bound to an MSTP process.
This step binds an interface to an MSTP process with a non-zero ID. If the interface belongs to process 0, skip this step.
- Run stp compliance { auto | dot1s | legacy }
The MSTP protocol packet format is configured on the interface.
- Run commit
The configuration is committed.
