Discover Keysight Network Bypass Switches

  • Pre-configured heartbeats: The only bypass to work with security tools through a single click, reducing setup times and eliminating potential errors during deployment.
  • Redundant or serial active tool support: Deploy multiple tools inline with a single bypass; the bypass supports active-standby and active-active network/security architectures.
  • High-density ports: iBypass VHD has the highest-density ports of any Bypass switch. Can protect up to 12 network links or 12 security devices.
  • Central management support: Ixia Fabric Controller Centralized Manager, the industry’s only centralized bypass management tool, simplifies and speeds configuration and management of tens to hundreds of devices.
  • Market-leading GUI: Easy-to-use interfaces support rapid deployment of complex topologies that are not possible with other vendors' bypass switches.
  • Multiple solutions: Keysight offers external bypass switches from 1G copper to 100G fiber — enabling complete independence from tool or packet broker failure.

What Is a Bypass Switch?

Bypass switches are network hardware devices that act as failsafe mechanisms for inline network devices — meaning they're directly within the path of incoming network traffic. In the case of maintenance, service disruptions, or network outages, bypass switches automatically redirect traffic to maintain the network's core functionality. In addition, bypass switches can also mirror network traffic — sending packets directly to monitoring tools or to network packet brokers for de-duplication and distribution.

Bypass Switches: Frequently Asked Questions

Bypass switches offer failsafe protection for inline network monitoring tools and flexibility for network architects and operations teams. Since bypass switches deploy directly in the line of incoming network traffic, it's easy to reroute network packets away from offline tools — minimizing the impact of device outages, maintenance, and downtime. 

Network bypass switches come in two different form factors: internal and external. Internal bypass switches are integrated into other network appliances, such as switches or network packet brokers. While their integrated functionality offers convenience, it comes at the cost of reduced control and flexibility.

In contrast to an integrated internal bypass switch, external bypass switches are separate devices that deploy on the network independently. Because these devices aren't linked to network appliances such as switches or network packet brokers, external bypass switches provide more control to network architects and operations teams.
