ONITORING
The Monitor function allows the operator to retrieve real time traces of traffic flowing on all ports. Real time
protocol level traces from any unit in the field can be seen and/or captured remotely. This function will
replace the need for a datascope or protocol analyzer for many diagnostic procedures, as well as allowing
these traces to be performed from a central console without manual dispatch. Access the Monitoring feature
from the
<4> Protocol Monitor
selection of the Functions For Port n menu.
The following display shows a sample basic real-time trace of an Ethernet port as displayed to a Telnet
session. It provides source and destination addresses, Transmit and Receive data messages, and a HEX
printout of the data.
Figure A-14. Protocol Monitor Trace Log
The monitor displays a notification message in the lower left corner of the screen when the operator pauses
and restarts the monitor. The indication will be either “Monitor Active” or “Monitor Paused”. Use
<Esc>
to
quit the monitor. Press
<Enter>
to pause or resume the monitor. Once in the monitor display there are
further options to allow the operator to display select parts of the frames, display data in ASCII instead of
HEX, display timestamps and filter the information displayed. For example, one has the ability to get an IP
header decode, or filter to select only frames from a specific MAC address, an IP address or IP address/
socket number. This
Port Monitor
menu is accessible by entering
<CTRL-O>
while in the protocol
monitor. The Port Monitor menu is shown in
Figure A-15
To return to the protocol monitor, enter
<Y>
to process selections (in the lower right) and enter
<Enter>,
or
press
<Esc>
to return to the protocol monitor.
