DWS-3160 Series Gigabit Ethernet Unified Switch CLI Reference Guide Chapter 13 BPDU Attack Protection Command List config bpdu_protection ports [ | all ] {state [enable | disable] | mode [ drop | block | shutdown} (1) config bpdu_protection recovery_timer [ | infinite] config bpdu_protection [trap | log] [none | attack_detected | attack_cleared | both] enable bpdu_protection disable bpdu_protection show bpdu_protection {ports {}} 13-1 config bpdu_protection ports Description This command is used to configure ports used by the BPDU protection function on the Switch. In generally, there are two states in BPDU protection function. One is normal state, and another is under attack state. The under attack state have three modes: drop, block, and shutdown. A BPDU protection enabled port will enter under attack state when it receives one STP BPDU packet. And it will take action based on the configuration. Thus, BPDU protection can only be enabled on STPdisabled port. BPDU protection has high priority than FBPDU setting configured by configure STP command in determination of BPDU handling. That is, when FBPDU is configured to forward STP BPDU but BPDU protection is enabled, then the port will not forward STP BPDU. Format config bpdu_protection ports [ | all ] {state [enable | disable] | mode [ drop | block | shutdown]}(1) Parameters - Specified a range of ports to be configured (port number). all - Specified that all the port will be configured. state - (Optional) Specified the BPDU protection state. The default state is disable enable - Specifies to enable BPDU protection. disable - Specifies to disable BPDU protection. mode - (Optional) Specifies the BPDU protection mode. The default mode is shutdown drop - Drop all received BPDU packets when the port enters under_attack state. block - Drop all packets (include BPDU and normal packets) when the port enters under_attack state. shutdown - Shut down the port when the port enters under_attack state. Restrictions Only Administrators, Operators and Power-Users can issue this command. 151
