The RMON Implementation
The following table summarizes the support in this product for the
nine standard groups of RMON. The table also specifies the
configuration of the various groups after system initialization.
A fter the default sessions are created, they have no special status. The
user can delete or change these parameters as required.
Two default alarms are created initially for each port, slot and repeater .
These are bandwidth used and errors /10000 packets. These can be
deleted or changed as required.
RMON is a very user-configurable system. The user can create multiple
monitoring facilities to run in parallel. Examples these facilities may be:
