    Gigabit Ethernet Switch User’s Guide Switch STP The Switch supports 801.2d Spanning Tree Protocol, which allows you to create alternative paths (with multiple switches or other types of bridges) in your network. See the Spanning Tree Algorithm section of the “Switch Management” chapter for a detailed explanation.
  • Page 109 Gigabit Ethernet Switch User’s Guide Time Since Topology Changes(sec) Read-only object displays the last time changes were made to the network topology. These changes usually occur when backup paths are activated due to primary path failures. Topology Change Count Read-only object displays the number of times (since the current management session with the device was started) changes were made to the network topology.
  • Page 110 Gigabit Ethernet Switch User’s Guide Hold Time(Sec) Read-only object displays the time interval during which no more than two configuration BPDUs shall be transmitted by the bridge. Root Priority(Sec) Read-only object displays the priority number of the root bridge of the Spanning Tree.
  • Page 111 Gigabit Ethernet Switch User’s Guide seconds. This is the time any port on the Switch spends in the listening state while moving from the blocking state to the forwarding state. Bridge Priority (0-65535 Sec) The Bridge Priority is a read-write object that can be from 0 to 65535. This is the priority number of the bridge.

    Gigabit Ethernet Switch User’s Guide STP State The Spanning Tree Protocol state for a selected port can either be Enabled or Disabled. Cost The Path Cost is a changeable parameter and may be modified according to the Spanning Tree Algorithm specification. The 100Mbps segment has an assigned Path Cost of 10, and each 10Mbps segment has an assigned Path Cost of 100.
