PRODUCT NAME: PROBEwatch for Windows, Version 1.0 SPD 46.03.00
DESCRIPTION
PROBEwatch for Windows[TM] is an applicaton for managing Digital's DEC-
packetprobe 90. DECpacketprobes monitor the network to which they are
attached, and make the statistical data available via the Remote Mon-
itoring (RMON) Management Information Base (MIB). PROBEwatch uses the
Simple Network Management Protocol (SNMP) to get the RMON MIB data from
the DECpacketprobes. You are provided with a Microsoft[R] Windows V3.1
graphical user interface, which makes the application easier to learn
and to use. It allows you to configure probes and to view the perfor-
mance data collected by the probes. PROBEwatch also contains an ex-
tensive protocol decode capability.
RMON
RMON is a proposed standard MIB specification written by the Inter-
net Engineering Task Force (IETF) RMON Working Group. The specifica-
tion for Ethernet has been designated RFC 1271. It provides for an agent,
acting on behalf of a client, to collect statistics on a per packet
basis by monitoring the network on which the agent is attached. The
agent-to-client communications take place via SNMP. The DECpacketprobe
is an implementation of an RMON agent, and PROBEwatch is Digital's im-
plementation of an RMON client. RFC 1271 calls for 9 separate groups
of MIB objects. The 9 groups are:
Segment statistics - counters for total number of packets, octets,
broadcasts, collisions, dropped packets, fragments, CRC/ alignment
errors, undersize and oversize errors, and jabbers; each packet is
also sorted by size into 1 of 6 size groupings; the RMON agent will
also count the number of packets that were dropped (not counted into
the categories above) due to performance limitations
History - segment statistics stored at user-defined intervals

Host Table - statistics indexed by node address
Host Top N - host statistics sorted by user-defined criteria
Traffic Matrix - traffic patterns between pairs of nodes
Filters - a set of user-defined preconditions for packet capture
or events
Events - logs an entry in a local log or sends an SNMP Trap when
a particular user-specified event occurs
Alarms - SNMP Traps generated when a high or a low threshold is crossed
Packet Capture - stores packets that meet the filter criteria for
later retrieval by a client application such as PROBEwatch
Version 1.0 of PROBEwatch for Windows does not support RFC 1513, the
Token Ring Extensions to the RMON MIB.
The opening screen in PROBEwatch displays a table of known DECpack-
etprobe agents. The user can then select one of these agents and look
at the statistics for that segment. Any of the variables in the Statis-
tics Group can be graphed over time. Short-term history and long-term
history graphs can be started in separate windows for several of the
variables in the Statistics Group. A choice of chart formats is made
available for each graph.
The user can choose to have PROBEwatch identify hosts by replacing the
first 3 bytes of the MAC address with the vendor name, whenever the
first 3 bytes can be associated with a known vendor. Optionally, hosts
can be identified by DECnet or IP address rather than by MAC address.
The user can select Discover from the menu to automatically translate
from MAC to IP address and name for addresses listed in the hosts file.
PROBEwatch has a window for viewing the list of discovered hosts and
sorting the list by various criteria, including discovery order, MAC
address order, or by several statistics from the RMON Statistics Group.
The user can select a pair of hosts and view the conversation statis-
tics between them. PROBEwatch supports the Top N Group through a win-
dow that lists hosts sorted by the various statistics of the Statis-
tics Group.

PROBEwatch provides the capability to upload captured files from DEC-
packetprobes to disk for subsequent decoding. Extensive protocol de-
coding exists for Novell[R], AppleTalk[R] Phase 1 and 2, Sun[R]/NFS[R],
DECnet and LAT, XNS, DoD TCP/IP suite, SNMP, VINES, SNA, and OSI. Each
layer of the OSI model can be displayed in a different color. PROBE-
watch allows the user to set up precapture filters, which help to zero
in on a particular node or protocol.
The PROBEwatch DomainView[TM] hides much of the setup work that is re-
quired in the RMON MIB to set up filters for common protocol suites.
A "domain" is a subset of all traffic on the segment, and is specific
to a particular protocol type. Domains are defined using filters in
the Filter Group. More than one DomainView can be active at the same
time on any one probe; a different DomainView can be set up by another
PROBEwatch management station. The PROBEwatch user can optionally en-
able statistics, hosts and conversations, or data capture separately
for each domain.
PROBEwatch can also be set up as an SNMP Trap receiver, not only from
DECpacketprobes, but from any device that sends Traps. PROBEwatch al-
lows the user to open a window to view the Traps that have been re-
ceived.
HARDWARE REQUIREMENTS
o Intel[TM] 80386DX, 33Mhz or higher performance IBM[R]-compatible
PC
o Color VGA or SVGA monitor - 800 x 600 (higher resolutions are not
supported)
o Minimum 8 MB RAM
o 3.5-inch diskette drive
o Minimum 12 MB of disk space
o Mouse or other pointing device supported by Windows V3.1
o Ethernet port (16 bit adapter recommended)
3
SOFTWARE REQUIREMENTS
o MS-DOS[R] V5.0 or higher
o Microsoft Windows 3.1
o NDIS driver for the Ethernet Network Interface Card (NIC)
PROBEwatch includes a basic UDP and IP protocol stack, but should work
with any stack compliant with the WINSOCK specification.
You can run PROBEwatch along with PATHWORKS Version 5.0. You can also
run HUBwatch for Windows Version 2.0 or later simultaneously with PROBE-
watch on the same PC, although you may want to increase the amount of
memory on the PC for acceptable performance.
GROWTH CONSIDERATIONS
The minimum hardware/software requirements for any future version of
this product may be different from the requirements for the current
version.
