GLOSSARY
A
AAA AAA refers to Authentication, Authorization, and Accounting, which is a security architecture for
distributed systems that determines the access given to users for specific services and the amount of
resources they have used.
aggregation A user-defined collection of network elements. For example, an aggregation can contain devices,
links, VPNs, and other aggregations.
alarm Sequence of event notifications that share the same source, cause, or fault. For example, if a single
port goes up and then down, these two events in a related sequence may result in a single alarm. An
alarm is stateful and is opened when a fault is first detected. Event notifications may be added to the
alarm, and it is archived when it is fixed.
association A relationship between the following types of network elements: a logical (protocol-oriented)
network element and a physical network element; a logical network element and anothe r logical
network element; or an existing association and anything else . A n exa mple f or a V PN woul d b e a n
