Command Manual – MSTPH3C S3100-52P Ethernet Switches Chapter 1 MSTP Configuration Commands1-19Caution:Disabling MSTP on ports may result in loops.Related command: stp mode, and stp.Example# Enable MSTP on Ethernet1/0/1 in system view. system-viewSystem View: return to User View with Ctrl+Z.[H3C] stp interface Ethernet 1/0/1 enable1.1.18 stp interface config-digest-snoopingSyntaxstp interface interface-list config-digest-snoopingundo stp interface interface-list config-digest-snoopingViewSystem viewParameterinterface-list: Ethernet port list. You can specify multiple Ethernet ports by providing thisargument in the format of interface-list ={ interface-type interface-number [ tointerface-type interface-number ] } &<1-10>, where &<1-10> means that you canprovide up to 10 port indexes/port index ranges for this argument.DescriptionUse the stp interface config-digest-snooping command to enable the digestsnooping feature.Use the undo stp interface config-digest-snooping command to disable the digestsnooping feature.By default, the digest snooping feature is disabled.According to IEEE 802.1s, two interconnected MSTP switches can interwork with eachother through MSTIs in an MST region only when the two switches have the same MSTregion-related configuration. Interconnected MSTP switches determine whether or notthey are in the same MST region by checking the configuration IDs of the BPDUsbetween them. (A configuration ID contains information such as region ID andconfiguration digest.)
