Command History
Usage Guidelines Use the rmon event command to configure the events for alarms.
The maximum number of RMON alarms currently is only configurable through the device manager and
threshold manager GUI. A CLI command is not available to change this maximum value.
Note We recommand setting alarm sample intervals to 30 seconds or higher to prevent excessive load on the
system.
alarm-number Specifies the RMON alarm number. The range is 1 to 65535.
mib-object Specifies the MIB object to monitor. Maximum length is 80 characters.
Note The MIB object identifier must be fully numbered, dotted-decimal
notation, not the text string description.

absolute Tests each sample directly.
delta Tests the difference (delta) between the current and previous sample.
rising-threshold value Specifies the rising threshold value. The range is –2147483648 to
2147483647.
