Initiating discovery
After preparing your deployment for discovery, you initiate an
IP Availability Manager
discovery for each IP Availability Manager
in the deployment. Then, you initiate an discovery by starting the component servers.During startup, the
MPLS Topology Server
:- Registers with theVMware Smart AssuranceBroker.
- Loads its .import (probe) and configuration files, including mpls.conf and mpls-tma.conf.
- Adds as a topology source eachIP Availability Managerthat is listed in the mpls.conf file.
- Creates in its repository an InChargeDomain object (INCHARGE-AM, for example) for eachIP Availability Managerinstance that is added as a topology source.
- Establishes a connection to eachIP Availability Managersource and probes each source for router and switch topology and CLI device-access objects.
- Imports and stores in its repository the router and switch topology that is discovered by eachIP Availability Managersource.
- Imports and stores in its repository the CLI device-access objects from theIP Availability Managersource that is exporting CLI device-access objects for operation.
- Initiates its own discovery by sending SNMP polls and/or CLI commands to the router and switch devices to discover the MPLS, VPN, and (optional) BGP information that is needed to build the MPLS, VPN, and BGP topology.Chapter 9, “Understanding Discovery Results,” provides information about discovery errors and their solutions.After initial discovery, and assuming that the StopAutoAMSync parameter in the mpls.conf file is FALSE (default), theMPLS Topology Serverimports topology fromIP Availability ManagerwheneverIP Availability Managercompletes a discovery cycle. “Synchronizing with IP Availability Manager” on page 126 describes how theMPLS Topology Serversynchronizes its discovery with the discovery ofIP Availability Manager.“Synchronizing with the MPLS Topology Server” on page 127 describes how theMPLS Monitoring Serverand theMPLS Analysis Servercomponents of synchronize their topology import with the discovery of theMPLS Topology Server.
