Outlines HA strategies for Cisco IoT FND, including solution component redundancy, DB HA setup, tunnel and router failover mechanisms, PKI integration, policy configuration, and troubleshooting methods to ensure reliable network operations.
HA components and configuration
This topic explains the concept of High Availability (HA) deployment for Cisco IoT FND, including its key components, how HA is achieved, and the required configurations at different levels.
Cisco IoT FND server HA
This topic explains how to achieve high availability (HA) for Cisco IoT FND servers using multiple application servers and load balancers, including configuration requirements and certificate considerations.
Load balancer
This topic explains the role and behavior of the load balancer in Cisco IoT FND High Availability (HA) environments, including its traffic management, health monitoring, and failover mechanisms.
Load-balancing policies
This topic explains the load-balancing policies used by the LB for different types of network traffic, including HTTPS, FAR, and IPv6 CSMP traffic.
DB HA
This topic explains how Cisco IoT FND Database High Availability (HA) is achieved using Oracle Active Dataguard, including configuration steps, helper scripts, and considerations for primary and secondary database deployment.
Set up the Cisco IoT FND DB for HA
Learn how to set up the Cisco IoT FND Database for high availability (HA) by configuring the standby and primary databases, Cisco IoT FND, and the database Observer.
Set up the standby DB
Learn how to set up the standby database server for high availability (HA) by running the setupStandbyDb.sh script and providing the required configuration information.
Set up the primary DB
Learn how to set up the primary database server for high availability (HA) by running the setupHaForPrimary.sh script and providing the required configuration information, including the standby database IP address.
Set up the observer
Learn how to set up the Observer on a separate server to monitor Oracle Data Guard configurations for high availability. Use this procedure to ensure the Observer is running and verify the database HA setup.
Validate Cisco IoT FND Oracle DB HA
Learn how to validate the FND Oracle database high availability (HA) setup by running commands to check database roles, flashback status, open mode, and synchronization between primary and secondary databases.
Disable Cisco IoT FND DB HA
Learn how to disable Cisco IoT FND Database High Availability (HA) by stopping the Observer, deleting the standby database, and removing the HA configuration from the primary server.
Tunnel HA
This topic explains tunnel high availability, including how Cisco IoT FND manages tunnels, the dependencies for tunnel redundancy, and the configuration steps required to ensure reliable tunnel operation in the network.
HER redundancy
This topic explains HER redundancy, focusing on the configuration steps required at both the FND and HER (ASR) to ensure dynamic Flex VPN connectivity in an IoT FND solution.
Configure tunnel provisioning policy
Learn how to configure tunnel provisioning policies in Cisco IoT FND to map FAR-to-HER interfaces and assign devices to tunnel groups using CSV or XML files.
Define a policy for mapping interfaces between FAR and HER
Learn how to define policies that determine the mapping between interfaces on FAR and HER using the Policy Name panel in the GUI.
FAR tunnel addition template
This topic explains how to modify the Field Area Router Tunnel Addition template to create multiple tunnels, including configuration steps and template macros for both IPsec and GRE tunnels.
HER tunnel addition template
This topic explains how to modify the Head-End Router Tunnel Addition template to create multiple tunnels, highlighting the changes made to the default configuration.
FAR redundancy
This topic explains the FAR Redundancy feature, which provides high availability for CGR1240 and CGM-WPAN-OFDM modules in mesh networks. It describes the deployment, key properties, and configuration steps required for a successful HA setup.
PKI
This topic explains the considerations and requirements for implementing high availability (HA) in Public Key Infrastructure (PKI) environments, including clustering support and configuration guidance for Certificate Authority and related services.
Troubleshoot
Use this topic to troubleshoot some of the common issues faced while configuring HA.
