Parameters
• msti instance — Enter the MST instance number (0 to 63).
• cost cost — (Optional) Enter a port cost value (1 to 200000000). Default values:
• 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
• priority value — Enter a value in increments of 16 as the priority (0 to 240, default 128) .
Default Priority value is 128
Command Mode INTERFACE
Usage Information The cost is a value based on the interface type. The greater the cost value, the less likely the port is selected to
be a forwarding port. The priority inuences the likelihood that a port is selected to be a forwarding port if
several ports have the same cost.
Example
OS10(conf-if-eth1/1/1)# spanning-tree msti 1 priority 0
OS10(conf-if-eth1/1/1)# spanning-tree msti 1 cost 3
Supported Releases 10.2.0E or later
spanning-tree port
Sets the port type as the EdgePort.
Syntax
spanning-tree port type edge
Parameters None
Default Not congured
Command Mode INTERFACE
Usage Information When you congure an EdgePort on a device running STP, the port immediately transitions to Forwarding state.
Only congured ports connected to end hosts act as EdgePorts.
Example
OS10(config)# spanning-tree port type edge
Supported Releases 10.2.0E or later
Rapid per-VLAN spanning-tree plus
RPVST+ is an RSTP to create a single topology per VLAN. RPVST+ is enabled by default, provides faster convergence, and runs on the
default VLAN (VLAN 1).
Conguring Rapid-PVST+ is a four-step process:
1 Ensure the interfaces are in L2 mode.
2 Place the interfaces in VLANs. By default, switchport interfaces are members of the default (VLAN1).
