Description

Use the stp config-digest-snooping command to enable Digest Snooping.

Use the undo stp config-digest-snooping command to disable Digest Snooping.

The feature is disabled by default.

Notice that:

z 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.

z It is not recommended to enable Digest Snooping on the MST region edge port to

avoid loops.

# Enable Digest Snooping globally.
