RMON options dialog box fields
This table describes the RMONOptions dialog box fields.
|
Enable
|
Globally enables or disables RMON.The default is disabled. Note that a rising event and a falling event are not created when you globally enable RMON from the Options dialog box.
|
UtilitizationMethod
|
Used to control whether RMON should use a half-duplex or full-duplex formula to calculate port utilization. When set to half-duplex, RMON will use InOctets and port speed to calculate port utilization. When set to full-duplex, RMON will use InOctets and OutOctets times the port speed to calculate port utilization.
|
TrapOption
|
Indicates whether RMON traps should be sent 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 can be configured by the user. However, when RMON is disabled, the memory allocated to RMON cannot be freed completely for use by other tasks. The memory is completely freed only when the switch is rebooted and RMON is disabled 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.
