NetSight Management

The NAC appliances are configured, monitored, and managed through management applications within the Enterasys NetSight Suite. NetSight is a family of products comprised of NetSight Console and a suite of plugin applications. Of the following NetSight applications, NetSight NAC Manager and NetSight Console are required for all four NAC deployment models, while NetSight Policy Manager and NetSight Inventory Manager are optional, depending on your network configuration and the network access control features you wish to implement. Following is a description of the NetSight applications.

NetSight NAC Manager

NetSight NAC Manager is a required core component in the Enterasys NAC solution. NAC Manager and NAC appliances work in conjunction to implement network access control. NAC Manager provides configurations for the assessment, authentication, authorization, and remediation parameters for all NAC appliances (NAC Gateways and NAC Controllers) from one centralized interface. After these configurations are enforced, the NAC appliances can detect, authenticate, assess, authorize, and remediate end‐systems connecting to the network according to those configuration specifications.
