2 Overview
Automatic Failover = Constant Link State —
Deploying in-line monitoring devices such as intrusion
prevention systems (IPS) or bridge devices like VPN gateways and firewalls used to mean a potential point
of failure on the network. When one of these devices malfunctioned or became overwhelmed with traffic,
network outages could occur. This posed serious challenges when deployed on mission critical links.
The DURA
stream
™
Bypass Switch ensures your network’s most important data does not fail even when
in-line devices do. Deploying a DURA
stream
™ Bypass Switch ensures uptime of critical links regardless
of in-line device performance by diverting critical network traffic away from malfunctioning in-line devices
until such devices are operating normally. This not only alleviates potential issues with traffic congestion
affecting link behavior caused by an IPS, it allows maintenance and upgrades of attached in-line tools
without network downtime.

DS-1010 10G Bypass Switch is an easy-to-manage external active bypass providing
failover and TAP capabilities for data monitoring of critical Gigabit network segments. Each bypass switch
offers up to four independent interface modules with a variety of media options (copper, fiber, and media
conversion). Each of the four network modules operates independently to ensure link protection monitoring
of one to four links at any time.
Line-rate throughput and real-time data forwarding hardware protects data and allows critical voice and
data applications to perform uninterrupted and meet high demands for quality and security. Deployed with
an in-line monitoring tool, a DURA
stream
™
Bypass Switch creates a comprehensive solution for intrusion
prevention.
Heartbeat Mode —
The DURA
stream
™
DS-1010 10G Bypass Switch can monitor the health of in-line
appliances by sending and receiving a heartbeat packet. A user programmable heartbeat packet can be
injected into the monitoring port link to determine availability of attached monitoring devices or help
determine delay due to high traffic volume. Even if a connected in-line tool is powered on, the bypass switch
can automatically switch traffic around it until the device returns to normal operation. At that time, traffic is
re-routed back to the monitor port.
Passive Mode —
In the event of power loss, the switch closes to create a physical connection, which in
turn, creates a passive bypass path to help prevent traffic interruption. Robust Management, Security and
Logging Manage your switch using built-in CLI or GUI, including secure web interface over HTTPS.
Supports secure shell (SSH), SNMP, e-mail notifications, as well as Syslog to enable
consolidation of log data from multiple systems into a central repository.
Reliable and Easy to Use —

DS-1010 10G Bypass Switch is simple to deploy,
enables plug-and-play connectivity, and is compatible with all major manufacturer’s monitoring systems.
Every unit not only comes with dual redundant power supplies to ensure monitoring uptime, the voltage of
each power supply is continuously monitored for instances of power decline or outage. In such cases, the
unit can initiate a switch to passive bypass mode.
