Note the following:

You must enable digest snooping on an interface first before enabling it globally.

Digest snooping is unnecessay if the interconnected switches are from the same vendor.

To enable digest snooping, the interconneted switches must be configured with the same settings.

To enable digest snooping, all interfaces in a MSTP domain used to connect other switches must have digest snooping enabled.

Do not enable digest snooping on border interfaces of an MSTP domain.

To change domain configuration, be sure to disable digest snooping first to prevent broadcast storm.
