Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
Advanced Management: RMON
The switch supports RMON (Remote Monitoring) on all connected network
segments. This allows for troubleshooting and optimizing your network.
The following RMON groups are supported:
■ Ethernet Statistics (except the numbers of packets of different frame sizes)
■ Alarm
■ History (of the supported Ethernet statistics)
■ Event
The RMON agent automatically runs in the switch. Use the RMON
management station on your network to enable or disable specific RMON
traps and events. Note that you can access the Ethernet statistics, Alarm, and
Event groups from the ProCurve Manager network management software. For
more on ProCurve Manager, visit the ProCurve Networking web site at

Click on products index, then look for the ProCurve Manager topic under the
Network Manager bar.
CLI-Configured sFlow with Multiple Instances
Up to three distinct sFlow instances can be configured via the CLI. Once
enabled, an sFlow receiver/destination can be independently configured for
full flow-sampling and counter-polling. CLI-configured sFlow instances may
be saved to the startup configuration to persist across a switch reboot.
Terminology
sFlow — An industry standard sampling technology, defined by RFC 3176,
used to continuously monitor traffic flows on all ports providing network-
wide visibility into the use of the network.
sFlow agent — A software process that runs as part of the network manage­
ment software within a device. The agent packages data into datagrams
that are forwarded to a central data collector.
sFlow destination — The central data collector that gathers datagrams from
sFlow-enabled switch ports on the network. The data collector decodes
the packet headers and other information to present detailed Layer 2 to
Layer 7 usage statistics.
