452 CHAPTER 10: RMON
Useful Information
And References
The following section provides useful details to do with RMON.
RMON RMON was defined by the user community with the help of the Internet
Engineering Task Force (IETF). It became a proposed standard in 1992 as
RFC 1271 (for Ethernet). RMON then became a draft standard in 1995 as
RFC 1757, effectively making RFC 1271 obsolete.
RFC 2819 is the latest specification for RMON. It redefines RFC 1757 in
SMIv2 format.
HC-RMON is defined in RFC 3273.
All RFC standards documents are available online at the IETF web site:

RMON Support on individual 3Com devices

RMON support on 3Com devices see
“
Supported Devices” on page 835.
RMON Limits on individual devices (for table creation)
Key Considerations You should try to delete RMON tables from a device when you no longer
require them. RMON tables take up resources on network devices, and
may affect the device's performance. Be careful not to delete RMON
tables which you have not yourself manually created. 3Com Network
Director creates and uses RMON tables for basic monitoring of the
network - removing these tables will adversely affect this functionality.
To manually delete tables from a device, see “
Managing RMON tables”
