Huawei quidway s7700 - Enabling the Digest Snooping Function

The interface is bound to an MSTP process.
NOTE
This step binds an interface to an MSTP process with a non-zero ID. If the interface belongs to process 0,
skip this step.
Step 4 Run:
stp compliance { auto | dot1s | legacy }
The MSTP protocol packet format is configured on the interface.
The auto mode is used by default.
NOTE
If the format of MSTP packets is set to dot1s on one end and legacy on the other end, the negotiation fails.

9.6.4 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
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 switching device in an MST region:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The Ethernet interface view is displayed.
Step 3 (Optional) Run:
stp binding process process-id
The interface is bound to an MSTP process.
NOTE
This step binds an interface to an MSTP process with a non-zero ID. If the interface belongs to process 0,
skip this step.
Step 4 Run:
stp config-digest-snoop
The digest snooping function is enabled.
