Configuring Layer 2 Interfaces

Configuring Unified Ports

If you're configuring a unified port as Fibre Channel or FCoE, confirm that you have enabled the feature fcoe command.

Procedure

 

Command or Action

Purpose

Step 1

switch# configure terminal

Enters global configuration mode.

Step 2

switch(config) # slot slot number

Identifies the slot on the switch.

Step 3

switch(config-slot) # port port

Configures a unified port as a native Fibre Channel port

 

number type {ethernet fc}

and an Ethernet port.

 

 

type—Specifies the type of port to configure on

 

 

 

a slot in a chassis.

 

 

ethernet—Specifies an Ethernet port.

 

 

fc—Specifies a Fibre Channel (FC) port.

 

 

Note

Changing unified ports on an expansion module

 

 

 

(GEM) requires that you power cycle the GEM

 

 

 

card. You do not have to reboot the entire

 

 

 

switch for changes to take effect.

Step 4

switch(config-slot) # copy

Copies the running configuration to the startup

 

running-config startup-config

configuration.

Step 5

switch(config-slot) # reload

Reboots the switch.

Step 6

switch(config) # no port port number

Removes the unified port.

This example shows how to configure a unified port on a Cisco Nexus 5548UP switch or Cisco Nexus 5596UP switch:

switch# configure terminal switch(config)# slot 1 switch(config-slot)# port 32 type fc

switch(config-slot)# copy running-configstartup-configswitch(config-slot)# reload

This example shows how to configure 20 ports as Ethernet ports and 12 as FC ports:

switch# configure terminal switch(config)# slot 1 switch(config-slot)# port 21-32 type fc

switch(config-slot)# copy running-configstartup-configswitch(config-slot)# reload

This example shows how to configure a unified port on a Cisco N55-M16UP expansion module:

switch# configure terminal switch(config)# slot 2 switch(config-slot)# port 16 type fc

switch(config-slot)# copy running-configstartup-configswitch(config-slot)# poweroff module 2 switch(config-slot)# no poweroff module 2

N5KC5596TFA specifications

The Cisco Systems N5KC5596TFA is a high-performance data center switch designed specifically for modern architectures requiring low-latency, high-bandwidth connectivity. As part of the Nexus 5000 series, the N5KC5596TFA addresses the needs of virtualized environments, cloud computing, and highly dynamic workloads, making it an essential choice for enterprises and service providers.

One of the standout features of the N5KC5596TFA is its impressive port density. The switch offers 48 10 Gigabit Ethernet (10GbE) ports and 4 40 Gigabit Ethernet (40GbE) uplinks, providing flexibility to connect a variety of devices and ensuring high throughput across the network. This port configuration is ideal for connecting multiple servers and storage devices, making it perfect for environments with significant data traffic.

The switch supports a range of advanced technologies such as Virtual Extensible LAN (VXLAN) for improving scalability and multi-tenancy in data center networks. VXLAN encapsulates Layer 2 Ethernet frames within Layer 4 UDP packets, allowing for a larger address space and effective overlay networking, which is crucial for cloud deployments.

Another notable aspect of the N5KC5596TFA is its support for Data Center Bridging (DCB), which enhances the reliability and performance of Ethernet networks. DCB features like Priority Flow Control (PFC) and Enhanced Transmission Selection (ETS) help to minimize data loss and ensure Quality of Service (QoS) for various types of traffic, including storage and regular data, which is critical in a converged infrastructure.

Security is also a priority with the N5KC5596TFA, as it comes equipped with features such as Access Control Lists (ACLs) and port security, helping to safeguard the network from unauthorized access and potential threats.

In terms of management, the switch offers integration with Cisco's Data Center Network Manager (DCNM), providing tools for monitoring, management, and automation, which simplifies operational tasks. Additionally, it supports Cisco's Application Centric Infrastructure (ACI), enabling a more comprehensive and application-focused approach to networking.

Overall, the Cisco Systems N5KC5596TFA is engineered for organizations looking to build robust, highly efficient, and secure data center environments. Its combination of high density, versatile connectivity options, and advanced networking technologies makes it a powerful solution for meeting the demands of today’s enterprise workloads.
