RMON Overview
RMON allows you to remotely monitor and analyze the activity of packets on CSS
Ethernet ports. RMON also allows alarm configuration for monitoring MIB
objects, and the event configuration to notify you of these alarm conditions. For
detailed information about RMON and its MIB objects, refer to RFC 1757.
The version of RMON provided on the CSS is a subset of the RMON-1 groups
(
Figure 6-1
). The CSS supports the following groups:
•
Group 1 - (Statistics) Provides data about all Ethernet ports on a CSS. You
cannot configure RMON statistics. You can only view them.
•
Group 2 - (History) Provides data about the Ethernet ports over an historical
period. Histories are preconfigured for each port. You can configure
additional port histories.
•
Group 3 - (Alarm) Allows you to create an alarm and configure the
conditions, based on a MIB object, to trigger an alarm when changes are
detected.
•
Group 9
- (Event) Allows you to create an event and configure the event
action that is to be performed when an associated alarm occurs.
