Stackable NWay Ethernet Switch User's Guide
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. Changes usually occur on the network
when backup paths are activated.
Designated Root Read-only object displays the MAC
(Ethernet) address of the bridge/switch on the network that
has been chosen as the STP root.
Root Cost Read-only object displays the cost for the path
between the switch and the root bridge. If the switch is the
root bridge, then the root cost is zero.
Root port Read-only object identifies the port (on the
bridge) that offers the least path cost from the bridge to the
root bridge. In the event of a network loop, data packets will
pass through the root port.
Max Age(Sec) Read-only object indicates the maximum age
of STP information learned from the network (on any port)
before it is discarded.
Forward Delay(Sec) Read-only object indicates how fast
any port on the bridge can change its spanning state when
moving towards the forwarding state. The value determines
how long the port stays in each of the listening and learning
states, which precede the forwarding state.
Hold Time(Sec)
during which no more than two configuration BPDUs shall be
transmitted by the bridge.
Root Priority Read-only object displays the priority
number of the root bridge of the Spanning Tree. The value is
used in conjunction with the bridge MAC address to set the
bridge ID, which in turn is used when determining the root
bridge of a multibridged network. The root bridge is
responsible for processing data packets when network loops
