Cisco 9348GC-FXP L2/L3 Gigabit Ethernet Manageable Switch 1U

In the data center, the Cisco Application Centric Infrastructure (Cisco ACI) solution is a unified architecture with centralized automation and application profiles that are based on policies.

The Cisco N9K-C9348GC-FXP ACI solution provides a robust transport network for today’s dynamic workloads

Cisco ACI is built on a network fabric that combines tried-and-true protocols with new ideas to make an architecture of low-latency, high-bandwidth links that is highly flexible, scalable, and reliable.

This fabric makes a network that can work in the most demanding and flexible data center environments.

The Cisco ACI fabric consists of three major components:

• Cisco Application Policy Infrastructure Controller (APIC);
• Spine switches;
• Leaf switches;

Building on the success of first-generation Cisco Nexus 9300 platform switches

The latest Cisco Nexus 9300-EX and 9300-FX platforms can collect comprehensive Cisco Tetration Analytics™ telemetry information at line rate across all ports without adding any latency to the packets or negatively affecting switch performance.

By default, this telemetry data is sent out every 100 milliseconds (ms) straight from the application-specific integrated circuit (ASIC) in the switch.

This information consists of three types of data:

• Flow information: This information contains information about endpoints, protocols, ports, when the flow started, how long the flow was active, etc.
• Interpacket variation: This information captures any interpacket variations within the flow. Examples include variations in Time To Live (TTL), IP and TCP flags, payload length, etc.
• Details about the context: Context information is gathered from places other than the packet header, such as changes in how buffers are used, packet drops within a flow, associations with tunnel endpoints, and so on.

The Cisco Tetration Analytics platform consumes this telemetry data, and by using unsupervised machine learning and behavior analysis, it can provide outstanding pervasive visibility across everything in your data center in real time.

By using algorithmic methods, the Cisco Tetration Analytics platform gives deep insights into how applications and interactions work.

This makes Cisco 9348 it possible to dramatically simplify operations, move applications to any programmable infrastructure, and use a "zero-trust" model.

These Layer 2 and Layer 3 nonblocking switches support 1, 10, 25, 40, 50, and 100 Gigabit Ethernet;

Fibre Channel over Ethernet (FCoE) and 8-, 16-, and 32-Gbps Fibre Channel (native Fibre Channel support is available on 9300-FX Small Form-Factor Pluggable (SFP) models only), with up to 3.6 terabits per second (Tbps) of internal bandwidth.

The 9300-FX switches also support the IEEE 802.1ae MAC Security (MACsec) standard on all downlink and uplink ports. This lets traffic be encrypted at the physical layer and provides secure connections between servers, border leaves, and leafs to spines.
