Topology Changed Count—The number of topology changes of Spanning Tree
for this port.
Total Forward Transitions—The total number of state transitions to a
forwarding state since the statistics were last cleared.
Total BridgeUp Time—The total amount of time, in seconds, that the bridge has
been active with Spanning Tree enabled. This count is valid only when Spanning
Tree is enabled for a bridged port.
ATM VC Statistics The ATM VC Statistics screen displays the following statistics:
VC#—The system-assigned virtual circuit number.
(Side A) card s/p—The slot and port number for side A of the circuit.
(Side A) rx—The receive VCI/VPI for side A.
(Side A) tx—The transmit VCI/VPI for side A.
(Side B) card s/p—The slot and port number for side B of the circuit.
(Side B) rx—The receive VCI/VPI for side B.(Side B) tx —The transmit VCI/VPI for
side B.
(Side B) Desc—The user-entered description of the circuit.
