Configured in system view, the setting takes effect globally.
Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all member ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate
interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port
leaves the aggregation group.
Enable this feature both globally and on ports connected to other vendors' devices to make it
effective. To minimize impact, enable the feature on all associated ports before you enable it globally.
When Digest Snooping is globally enabled, if you modify the VLAN-to-instance mapping or use the
undo stp region-configuration
command to restore the default MST region configuration, traffic
might be interrupted because the local VLAN-to-instance mapping is different from that on a
neighbor device. Perform these operations with caution.
