Page 13: Stp Bpdu-Protection
Command Manual – MSTP H3C S3100-52P Ethernet Switches Chapter 1 MSTP Configuration Commands After MSTP is enabled, the actual operating mode, which can be STP-compatible mode, RSTP-compatible mode, or MSTP mode, is determined by the user-defined protocol mode. A switch becomes a transparent bridge if MSTP is disabled. -
Page 14: Stp Bridge-Diameter
[H3C] stp bpdu-protection Caution: As Gigabit ports of an S3100-52P Ethernet switch cannot be shut down, the BPDU protection function is not applicable to these ports even if you enable the BPDU protection function and specify these ports to be MSTP edge ports. -
Page 15: Stp Compliance
Command Manual – MSTP H3C S3100-52P Ethernet Switches Chapter 1 MSTP Configuration Commands Use the undo stp bridge-diameter command to restore the network diameter to the default value. After you configure the network diameter of a switched network, MSTP adjusts its hello time, forward delay, and max age settings accordingly. -

Command Manual – MSTP H3C S3100-52P Ethernet Switches Chapter 1 MSTP Configuration Commands port to prevent network storm. A port shut down in this way can only be enabled again by the network administrator after login. With the MSTP packet format set to legacy, the port only processes and transmits MSTP packets in legacy format, thus implementing interconnection with the peer devices transmitting packets in legacy format. - Page 17 Command Manual – MSTP H3C S3100-52P Ethernet Switches Chapter 1 MSTP Configuration Commands According to IEEE 802.1s, two interconnected switches can interwork with each other through MSTIs in an MST region only when the two switches have the same MST region-related configuration.
