IPX Port Statistics

The IPX Port Statistics dialog box displays information pertaining to the IPX Port; for example, the

frame type used or the number of packets transmitted/received.

IPX is a network layer protocol usually associated with Novell Netware

networks. It allows for

encapsulation of four different frame types over a single physical LAN connection (provided each

frame type has a unique network address): RAW (802.3), LLC (802.2), Ethernet II, and SNAP.

These statistics are mostly informational but could be useful for troubleshooting. For instance, if there

was a question as to which frame type your workstation was using, you could view the statistics for

each frame type and determine which one is being used by the amount of packets transmitted and

received.

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 an IEEE 802.1D telecommunications 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 automatically from blocking to forwarding any time a root bridge failure

occurs.

The STP Port statistics are mostly informational but can also be useful for troubleshooting. For

example, you can check the number of forward transitions to ensure that the port has been active (in

which case forward transitions will be greater than zero).
