stp config-digest-snooping
Use stp config-digest-snooping to enable Digest Snooping.
Use undo stp config-digest-snooping to disable Digest Snooping.
Syntax
stp config-digest-snooping
undo stp config-digest-snooping
Default
The feature is disabled by default.
Views
System view, Ethernet interface view, Layer 2 aggregate interface view
Default command level
2: System level
Usage guidelines
Configured in system view, the setting takes effect globally.
Configured in Ethernet interface view, the setting takes effect only on the interface.
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.
Examples
# Enable Digest Snooping on GigabitEthernet 0/1 and then globally.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] stp config-digest-snooping
[Sysname-GigabitEthernet0/1] quit
[Sysname] stp config-digest-snooping
