Description
Use the
undo stp config-digest-snooping
Snooping.
The feature is disabled by default.
Notice that:
You need to enable this feature both globally and on ports connected to other
■
vendors' devices to make it take effect. It is recommended to enable the
feature on all associated ports first and then globally, making all configured
ports take effect at the same time to minimize the impact, and disable the
feature globally to disable it on all associated ports.
It is not recommended to enable Digest Snooping on the MST region edge port
■
to avoid loops.
Refer to "Link Aggregation Configuration Commands" on page 473 for
■
information about port groups.

instance instance-id: Sets the path cost of the port(s) in a particular MST instance.
The minimum value of instance-id is 0, representing the CIST, and the maximum
value of instance-id is 15.
cost: Path cost of the port, the effective range of which depends on the path cost
calculation standard adopted.
Use the stp cost command to set the path cost of the port(s) in the specified MST
instance or all MST instances.
