HP ProCurve Switch 4000M / 8000M / 2424M / 1600M Reviewer’s Guide
• HP OpenView platforms - If management of a generic IP network is needed (i.e. management of
HP and other vendor’s devices):
NT platform - bridge software to HP OpenView/NT is available so that TopTools can run
under HP OpenView/NT. For more details see the TopTools web site at
http://www.hp.com/toptools .
UX platform - Management of the HP ProCurve Switch 4000M/8000M/2424M/1600M under
HP OpenView/UX is available via the separately purchased J3250M HP Hub & Switch
Management For HP OpenView-UX product.
TopTools will also run under Tivoli Enterprise and Tivoli NetView, as well as Unicenter TNG using the
proper bridges to these environments. See the TopTools web site at http://www.hp.com/toptools for
more details.
For more details on network management of HP hubs and switches, see the separate Managing HP
Hubs and Switches Reviewer’s Guide.
Net management features unique to the HP ProCurve Switch 4000M/8000M/2424M/1600M are described
below.
2.15.1 MIB Support
The HP ProCurve Switch 4000M/8000M/2424M/1600M supports the following standard MIBs:
• MIB-II (RFC 1213)
• Bridge MIB (RFC 1493)
• Ethernet MAU MIB (RFC 1515)
• Interfaces Evolution MIB (RFC 1573)
• Ethernet Interface MIB (RFC 1650)
• RMON MIB (RFC 1757)
Groups: (1) Ethernet statistics, (2) Ethernet history, (3) Alarm, (9) Event,
In addition, a number of enterprise-specific MIBs are also supported for such things as VLANs, network
management, TFTP parameters, and values needed for software download.
2.15.2 RMON Support
For those customers that use RMON applications, the HP ProCurve Switch 4000M/8000M/2424M/1600M
support RMON groups 1 (Ethernet statistics), 2 (Ethernet history), 3 (Alarm), and 9 (Event). These four
groups are available for all ports.
The Ethernet statistics group provides counters for packet counts, broadcast/multicast packets, packet
length counts, missed packets and erred packets. Event and Alarm groups allow threshold setting and
alarm generation based on the counters in the Ethernet group. History accumulates these counters over
a period of time (30 samples deep).
2.15.3 HP Extended RMON
HP Extended RMON is the embedded sampling technology that allows HP TopTools to provide
network traffic information in an effective and cost-efficient way. HP Extended RMON looks at traffic
on all ports of a HP switch and/or hub simultaneously without burdening CPU performance. HP
Extended RMON is composed of two parts: the sampling agent residing in most HP hubs and switches,
and the data collector in HP TopTools for Hubs & Switches. HP Extended RMON technology has been
included in many HP hubs and switches since 1992.
Because HP Extended RMON is a sampling technology that requires very little in terms of system
resources, it is easily scaleable to monitor switched and shared high-speed technologies, such as
Gigabit Ethernet, 100Base-T and FDDI.
HP Extended RMON is statistically accurate to a 95-percent confidence level. The sampling rate is
adjusted once per hour to maintain this confidence level. This accuracy is more than adequate for
