• Actions are identical to Observer’s standard actions.
• RMON Limitations: Only statistics kept in the statistics group (RMON1 Group 1) are
triggered upon.
• Notes: The following information on each statistics group 1 item is taken directly
from the RMON1 MIB. Each vendor’s RMON implementation should follow the
described metric for each item. RMON timing for any trigger that tracks a time
interval is 1/100th of a second. Additionally, each trigger (except the Occurrence of a
hardware address and the Sequence of bytes at an offset) allows configuration to
trigger on either a specific value floor or ceiling, a floor or ceiling value per second,
or a floor or ceiling delta between sampling periods.
