Chapter 4: Statistics

•Spanning Tree - the port's Spanning Tree state. This entry shows status only; it is not selectable. The following states apply to Spanning Tree:

-Blocking - The port is not currently the designated port to the LAN and is therefore not forwarding any packets. (This means there is another route to that LAN and, since the Spanning Tree protocol does not allow simultaneous redundant paths, this port is blocked. If the other route to that LAN goes down, this port would then begin forwarding packets.)

-Listening - The port is listening for other bridges on the network to determine if it should go to the forwarding or blocking state.

-Learning - The port is listening for other bridges on the network and making a table of addresses from packets that it has received. Once the port goes to the forwarding state, it can then use the address information it has learned.

-Forwarding - The port is the designated port for the LAN and is forwarding packets and sending out bridge protocol packets.

-Broken - The port is not forwarding packets. Reasons include no cable connected, no link status, the ring is not operational, or an NMS has disabled the port.

-Disabled - The port is not configured for Spanning Tree.

•Packets Transmitted - number of packets transmitted from the port. This entry shows status only; it is not selectable. This includes any packets that might have experienced transmission errors. (The port’s statistics are reset whenever the port is started.)

•Packets Received - number of good packets received through the port. This entry shows status only; it is not selectable. Packets with reception errors are not included, nor are packets local to that segment that are hardware filtered.

•Small Buffers - number of buffers currently assigned to the port (see RX_Q Overflows below). This entry shows status only; it is not selectable.
