spanning-tree mstp edge-port Configures the interface as an MST edge port and optionally a Bridge Protocol Data Unit (BPDU) guard. C-Series, E-Series, S-Series, Z-Series Syntax Parameters spanning-tree mstp edge-port [bpduguard [shutdown-onviolation]] mstp edge-port bpduguard shutdownonviolation Enter the keyword mstp followed by the keywords edge-port to configure the interface as a Multiple Spanning Tree edge port. (OPTIONAL) Enter the keyword portfast to enable Portfast to move the interface into forwarding mode immediately after the root fails. Enter the keyword bpduguard to disable the port when it receives a BPDU. (OPTIONAL) Enter the keywords shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. Command Modes Command History INTERFACE Version 8.3.11.1 Version 8.2.1.0 Version 7.6.1.0 Version 7.5.1.0 Version 6.5.1.0 Introduced on the Z9000. Introduced the hardware shutdown-on-violation option. Introduced on the S-Series. Introduced on the C-Series. Introduced on the E-Series. Usage Information On an MSTP switch, a port configured as an edge port immediately transitions to the forwarding state. You should only configure ports connected to end-hosts as edge ports. Consider an edge port similar to a port with spanning-tree portfast enabled. If you do not enable shutdown-on-violation, BPDUs are still sent to the RPM CPU. tc-flush-standard Enable the MAC address flushing after receiving every topology change notification. C-Series, E-Series, S-Series, Z-Series, S4810 Syntax Defaults tc-flush-standard To disable, use the no tc-flush-standard command. Disabled. 1114
