Packet Trace
NT/MPRI – 5 Connection Management and Monitoring 80
Events can be displayed either as a daily report or as a selection of
events.
l Daily Report of Events:
The daily report of events provides a precise overview of all ISDN
messages and any error messages. This protocol is arranged
chronologically with the most recent messages first.
l Selection of Events:
In this input mask can be defined precisely which ISDN events the
NT/MPRI displays. The information can be selected by type of
message, call destination or ISDN-Controller and restricted to any
time period desired. When searching error messages to locate
sources of trouble, for example, it can be useful to view all incom-
ing or outgoing calls or all messages for a given call destination or
a certain controller.
Packet Trace
The “Packet Trace” function can be used to identify which protocol
packets are being sent in the LAN and over ISDN. In this way it is possi-
ble to localize the causes of excessive connection charges, to record
the PPP negotiation for connections and to verify the effectiveness of
the enabled spoofing functions.
A number of options can be defined for tracing, such as the protocol
layer to be traced. Other possibilities include specifying the destina-
tion of packets and whether tracing is to be performed on all or just
one specific network adapter.
The following section presents two examples of what to do to configure
packet tracing.
