CPAA overview

CPAA route analyzer

The CPAA collects and analyzes routing data from the routing areas to which it is connected. Traffic on the CPAA is restricted to control data and packages directly destined to the CPAA. Because no other traffic can pass through it, the CPAA only advertises itself to its neighbor routers and does not re-advertise link-state data received from its neighbors.

The CPAA uses a passive version of the 7750 SR OS, and acts as a special-purpose routing element that passively peers with the network to capture a real-time view. The 7701 CPAA and vCPAA are managed by the NFM-P like any other NE. Management procedures such as timing synchronization, polling, deployments, and NE resynchronization are similar to procedures for other SR OS devices. See the NSP NFM-P User Guide for information about general device management functions.

The following are the main functions of a CPAA:

listening to routing data from the routing protocols that are running on it
providing route calculation for routes passing through the routing areas the CPAA is responsible for
performing routing analysis and providing the results to the CPAM, so the CPAM can generate network-wide reports or alarms

For information about CPAA functions and deployment under the NFM-P CPAM feature set, see the NSP NFM-P Control Plane Assurance Manager User Guide.

7701 CPAA hardware and vCPAA

The CPAA exists as a hardware chassis and as a virtual CPAA (vCPAA).

This guide describes software installation and upgrade, commissioning and discovery, and redundancy for both the 7701 CPAA hardware and vCPAA.

For information about specifications and setup of the 7701 CPAA hardware, consult the 7701 CPAA Setup and Installation Guide that corresponds to the original hardware and software release at time of purchase.

CPAA alarm support

All alarms supported in CPAA Release 8.0 are also supported in CPAA Release 9.0 and CPAA Release 10.0.

The 7701 CPAA hardware rev.2 and vCPAA do not support power supply alarms or power failure alarms. The CPAA OS has no visibility of the power supply, and cannot detect power interruptions.

Use subject to agreed restrictions on disclosure and use.
