Enable RMON Globally

About this task

You must globally enable RMON before you can use RMON2 functions. If you attempt to enable an RMON2 function before the global flag is disabled, EDM informs you that the flag is disabled and prompts you to enable the flag. You can configure RMON1 while RMON is globally disabled.

If you want to use nondefault RMON parameter values, you can configure them before you enable RMON, or as you configure the RMON functions.

Description

Enable

Enables RMON. If you select Enable, the RMON agent starts immediately. To disable RMON, clear Enable, select Apply, and then restart the device. The default is disabled.

UtilizationMethod

Controls whether RMON uses a half-duplex or full-duplex formula to calculate port usage. After you select halfDuplex, RMON uses InOctets and the speed of the port to calculate port usage (this is the standard RMON RFC 1271 convention). After you select fullDuplex, RMON uses InOctets and OutOctets and 2X the speed of the port to calculate port usage. If you select fullDuplex, but the port operates in half-duplex mode, the calculation defaults to the RFC 1271 convention. The default is halfDuplex.
