Installation and Getting Started Guide
See the "Configuring IP" chapter in the Advanced Configuration and Management Guide for information.
HP devices support SNMPv2c, including support for GetBulk requests. The SNMPv2c support is enabled by
default and cannot be disabled. Thus, you do not need to perform any configuration on the device to use the
feature. SNMPv1 also is enabled by default.
NOTE: You can disable all SNMP access to the device if needed. See "Disabling Specific Access Methods" on
To use this enhancement, you need an SNMP management application that is capable of sending GetBulk
requests. See the documentation for your application for more information.
NOTE: The SNMPv2c support does not include support of SNMPv2c traps.
Remote Monitoring (RMON) Statistics
All HP devices include an RMON agent that supports the following groups. The group numbers come from the
RMON specification (RFC 1757).
Statistics (RMON Group 1) – Current packet and error statistics for each port.
History (RMON Group 2) – Samplings of packet and error statistics captured at regular intervals. You can
configure the sampling rate and the number of "buckets" in DRAM for storing the samplings.
Alarms (RMON Group 3) – A list of alarm events, which indicate that a threshold level for a specific part of the
device has been exceeded. You can select the system elements you want RMON to monitor and the
thresholds for triggering the alarms.
Events (RMON Group 9) – A log of system events (such as port-state change to up or down, and so on) and
alarms. RMON Group 9 also specifies the action to be taken if an alarm threshold is exceeded.
See the "Network Monitoring" appendix in the Advanced Configuration and Management Guide for information
about setting and displaying the RMON statistics.
In addition to the event and alarm logs provided by RMON, HP devices contain a Syslog agent that can write log
messages to a local buffer and optionally to a third-party SyslogD server.
at the following severity levels:
The device automatically writes the Syslog messages to a local buffer. If you specify the IP address or name of a
SyslogD server, the device also writes the messages to the SyslogD server. The default facility for messages
written to the server is "user". You can change the facility if needed. You also can change the number of entries
that can be stored in the local buffer. The default is 50. HP devices do not have a limit to the number of messages
that can be logged on a remote SyslogD server.
