Useful Information The following section provides useful details to do with RMON.

And References

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.

RMON Support on individual 3Com devices

For more information about 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” on page 447.
