Product Overview
The Cis co Nexus® 3016 Switch (Figure 1) is a 40 Gigabit Ethernet switch platform. It
is a high-performance, ultralow-latency Ethernet switch providing
line-rate Layer 2 and 3 switching in a compact one-rack-unit (1RU)
form factor. The switch runs the industry-leading Cis co® NX-OS Software operating system, providing customers with robust
features and functions that are widely deployed globally.
The line-rate Layer 2 and 3 switching at ultra-low latencies along
with the serialization benefits of 40 Gigabit Ethernet switching
make the Cis co Nexus 3016 an ideal switch platform for financial
co-locations. This switch supports both forward and reversed
airflow schemes with AC and DC power inputs.

Main Benefits
The Cis co Nexus 3016 provides the following main benefits:
1. Ultra-low latency
. The Cis co Nexus 3016 delivers ultra-low nominal latency that
enables customers to implement high-performance infrastructures for
high-frequency trading workloads. Customers can also achieve faster
application performance because of the serialization savings from
switching at 40 Gigabit Ethernet speeds.
2. Wire-rate Layer 2 and 3 switching on all ports
. Layer 2 and 3 switching of up to 1.2 terabits per second (Tbps) and
more than 950 million packets per second (mpps) is provided in a
compact 1RU form-factor switch.
3. Purpose-built on Cis co NX-OS operating system with comprehensive,
proven innovations
. Virtual PortChannel (vPC) provides Layer 2 multipathing through the
elimination of Spanning Tree Protocol and enables fully utilized
bisectional bandwidth and simplified Layer 2 logical topologies
without the need to change the existing management and deployment
models.
. Power On Auto Provisioning (POAP) enables touchless bootup and
configuration of the switch, drastically reducing provisioning
time.
. Cis co Embedded Event Manager (EEM) and Python scripting enable
automation and remote operations in data center.
