Range: zero (0) to 63 (OPTIONAL) Enter the keyword cost followed by the port cost value. Range: 1 to 200000 Defaults: • 100 Mb/s Ethernet interface = 200000 • 1-Gigabit Ethernet interface = 20000 • 10-Gigabit Ethernet interface = 2000 • Port Channel interface with one 100 Mb/s Ethernet = 200000 • Port Channel interface with one 1-Gigabit Ethernet = 20000 • Port Channel interface with one 10-Gigabit Ethernet = 2000 • Port Channel with two 1-Gigabit Ethernet = 18000 • Port Channel with two 10-Gigabit Ethernet = 1800 • Port Channel with two 100-Mbps Ethernet = 180000 Enter keyword priority followed by a value in increments of 16 as the priority. Range: 0 to 240. Default: 128 cost = depends on the interface type; priority = 128 INTERFACE Version 8.3.19.0 Version 8.3.7.0 Version 7.6.1.0 Version 7.5.1.0 Version 6.5.1.0 Introduced on S4820T Introduced on S4810 Added support for S-Series Added support for C-Series Introduced on E-Series spanning-tree mstp c e s Configures a Layer 2 MSTP interface as an edge port with (optionally) a Bridge Protocol Data Unit (BPDU) guard, or enables the root guard or loop guard feature on the interface. Syntax Parameters spanning-tree mstp {edge-port [bpduguard [shutdown-on-violation]] | loopguard | rootguard} edge-port bpduguard shutdown-on-vi olation Enter the keyword 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 keyword shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. 1046 | Multiple Spanning Tree Protocol (MSTP)
