Network Monitoring
This chapter provides a general overview of monitoring tools supported on HP ProCurve switches and routing
switches. Configuration examples are provided using the CLI and Web management interfaces.
RMON Support
All HP ProCurve switches and routing switches come standard with an RMON agent that supports the following
groups. The group numbers come from the RMON specification (RFC 1757).
• Statistics (RMON Group 1)
• History (RMON Group 2)
• Alarms (RMON Group 3)
• Events (RMON Group 9)
The CLI allows you to make configuration changes to the control data for these groups, but you need a separate
RMON application to view and display the data graphically.
Statistics (RMON Group 1)
Count information on multicast and broadcast packets, total packets sent, undersized and oversized packets, CRC
alignment errors, jabbers, collision, fragments and dropped events is collected for each port.
No configuration is required to activate collection of statistics. This activity is by default automatically activated at
system start-up.
USING THE CLI
You can view a textual summary of the statistics for all ports by entering the following CLI command:
HP9300(config)# show rmon statistics
Syntax: show rmon statistics
NOTE: To see RMON statistics for an individual port only, enter the following command noting a specific port
entry number: show rmon statistics <entry-number>.
USING THE WEB MANAGEMENT INTERFACE
To view the RMON statistics for the system:
1. Log on to the device using a valid user name and password for read-only or read-write access. The System
configuration dialog is displayed.
