RmonOptions dialog box items


Item Description
Enable
Globally enables or disables RMON.The default is false (disabled). Note that a rising event and a falling event are not created when you globally enable RMON from the Options dialog box. For an explanation of how events work, refer to "Alarms" on "Alarms".
SaveConfig
When this box is checked, the RMON configuration is saved when the switch configuration is saved to NVRAM.
TrapOption
Indicates whether you should send RMON traps to only the owner of the RMON alarm (the individual that created the alarm entry) or to all trap recipients in the system trap receiver table. The default setting is toOwner.
MemSize
Amount of RAM in bytes to allocate for RMON to use when rcSysRmonEnable is "true." The default memory size is 250 KB (250,000 bytes). The range limit is 4,000,000 bytes. The more memory allocated to RMON, the greater the number of RMON alarms, events, and so forth that the user can configure. However, when RMON is disabled, the memory allocated to RMON is not completely free for use by other tasks. The memory is completely available only when you reboot the switch and disable RMON at the time of the reboot.
Because RMON takes memory from the common memory pool, allocating a large amount of memory to RMON can affect such things as the number of routes, IP addresses, or MAC entries that the system can support.
UtilizationMethod
Indicates whether you should use half-duplex or full-duplex mode to calculate port utilization. When the half-duplex formula is used, port utilization is calculated based on the incoming traffic only. If you select full AND the port's OperDuplex is full, the utilization is the average of the incoming and outgoing traffic. If you select full AND the OperDuplex is half, the half-duplex utilization is calculated.

If you want to use nondefault RMON parameter values, you should set them before enabling RMON or when you create the specific RMON function.
