Chapter 4 - MultiFRAD Software
IPX is a network layer protocol usually associated with Novell Netware TM 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).
SNMP Statistics
The SNMP Statistics dialog box provides statistical information on Simple Network Management
Protocol (SNMP).
