Parameter cost Description Enter th keyword cost followed by the cost value to change the interface's spanning tree path cost. Range Default 165535 port-priority Change the spanning tree priority. 0 - 255 128 vlan range Enter the keywords vlan range followed by the range - - of VLAN iID's. Separate the VLAN IDs with a hyphen, comma or both to indicate the range. For example: 2-3 or 2,4,6 or 26,11 Usage Guidelines Dell supports global instances of RSTP and PVST+. Therefore, the ports on industry-standard routers/switches must be on the default or untagged VLAN for interoperability with controllers. ArubaOS supports RSTP on the following interfaces: l FastEthernet IEEE 802.3-fastethernet l Gigabitethernet IEEE 802.3-gigabitethernet l Port Channel ID-port-channel In addition to port state changes, RSTP introduces port roles for all the interfaces. RSTP (802.1w) Port Role Description Root The port that receives the best BPDU on a bridge. Designated The port can send the best BPDU on the segment to which it is connected. Alternate The port offers an alternate path, in the direction of root bridge, to that provided by bridge's root port. Backup The port acts as a backup for the path provided by a designated port in the direction of the spanning tree. Example The RSTP default values are adequate for most implementation. Use caution when making changes to the spanning tree values. (host) (config-if) #spanning-tree cost 345 (host) (config-if) #spanning-tree point-to-point ?
