Tunneling and ERSPAN Termination

Extend monitoring to remote sites and the cloud

The Tunneling feature is a licensable addition to the GigaSMART® engine that helps alleviate blindness of business-critical traffic at remote sites, virtualized data centers, or hosted in a public cloud. Tunneling is used in conjunction with Flow Mapping® technology to select traffic at remote sites that should be subject to additional inspection. That traffic subset can then be forwarded via IP/UDP or L2GRE encapsulation to centralized monitoring and security resources. Tunneling also works with GigaVUE-VM for VMware, GigaVUE-VM for OpenStack, and Visibility Platform for AWS to select and tunnel traffic from within virtual environments to the Gigamon® Visibility Platform via L2GRE tunnels. With Tunneling, physical networks can utilize cloud-based tools and load balance across multiple instances.

Benefits of the Tunneling feature

Provides security teams with access to suspicious traffic anywhere within the organization, local or remote, physical or virtual.
Eliminates the cost of deploying and managing tools at branch offices and remote sites.
Preserves the processing power of hypervisors to handle workload, instead of management and monitoring.
Immediately extends monitoring and security to new acquisitions or temporary installations until other arrangements can be made.
Enables load balancing across multiple IP-addressable virtual and cloud-based tools.
Allows operators to take advantage of existing Cisco NEXUS features by forwarding traffic via ERSPAN tunnels to the Gigamon Visibility Platform.
