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.
