1.1.18 stp interface config-digest-snooping

Syntax
stp interface interface-list config-digest-snooping
undo stp interface interface-list config-digest-snooping
View
System view
Parameter
interface-list: Ethernet port list. You can specify multiple Ethernet ports by providing this
argument in the format of interface-list ={ interface-type interface-number [ to
interface-type interface-number ] } &<1-10>, where &<1-10> means that you can
provide up to 10 port indexes/port index ranges for this argument.
Description
Use the stp interface config-digest-snooping command to enable the digest
snooping feature.
Use the undo stp interface config-digest-snooping command to disable the digest
snooping feature.
By default, the digest snooping feature is disabled.
According to IEEE 802.1s, two interconnected MSTP switches can interwork with each
other through MSTIs in an MST region only when the two switches have the same MST
region-related configuration. Interconnected MSTP switches determine whether or not
they are in the same MST region by checking the configuration IDs of the BPDUs
between them. (A configuration ID contains information such as region ID and
configuration digest.)
