Note: Loop guard is not supported in the show spanning-tree rstp guard command. spanning-tree rstp Configure an RSTP interface with one of these settings: port cost, edge port with optional Bridge Port Data Unit (BPDU) guard, port priority, loop guard, or root guard. Syntax spanning-tree rstp {cost port-cost | edge-port [bpduguard [shutdown-on-violation] | bpdufilter] | priority priority | {rootguard}} Parameters cost port-cost edge-port bpduguard shutdown-on-vi olation bpdufilter priority priority rootguard Enter the keyword cost followed by the port cost value. Range: 1 to 200000 Defaults: 10-Gigabit Ethernet interface = 2000 40-Gigabit Ethernet interface = 1400 Port Channel interface with one 10-Gigabit Ethernet = 2000 Port Channel interface with one 40-Gigabit Ethernet = 1400 Port Channel with two 10-Gigabit Ethernet = 1800 Port Channel with two 40-Gigabit Ethernet = 600 Enter the keyword edge-port to configure the interface as a Rapid 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 keyword shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. (OPTIONAL) Enter the keyword bpdufilter to enable BPDU Filter to stop sending and receiving BPDUs on port enabled interfaces. Enter keyword priority followed by a value in increments of 16 as the priority. Range: 0 to 240 Default: 128 Enter the keyword rootguard to enable root guard on an RSTP port or port-channel interface.
