STP (Spanning Tree) Port Statistics
The STP (Spanning Tree) Port Statistics dialog box displays information regarding the selected STP
port, for example, the number of frames discarded or forwarded.
Spanning Tree transParent (STP) bridging is the method of bridging used by the MultiFRAD as
specified in IEEE 802.1d standard. Enabling the spanning tree algorithm in addition to spanning tree
bridging provides for a loop-free environment with redundant paths (if present) that will transition from
blocking to forwarding automatically in case of a root bridge failure.
The STP Port statistics are mostly informative but may be helpful in troubleshooting. For example,
viewing the number of forward transitions could indicate if the port has ever become active (in which
case forward transitions will be greater than zero).
