Enabling the Digest Snooping Function

When a Huawei device is connected to a non-Huawei device, if the region names, revision numbers, and VLAN-to-instance mappings configured on the two devices are consistent but the Bridge Protocol Data Unit (BPDU) keys are different, the two devices cannot communicate. To address this problem, enable the digest snooping function on the Huawei device.

Context

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 config-digest-snoop
The digest snooping function is enabled.
Run commit
The configuration is committed.
