Configuring Layer 2 Interfaces

Port Profiles

This example shows how to add the interface commands to a port profile named ppEth configured for Ethernet interfaces:

switch# configure terminal switch(config)# port-profile ppEth switch(config-port-prof)# switchport mode trunk

switch(config-port-prof)# switchport trunk allowed vlan 300-400 switch(config-port-prof)# flowcontrol receive on switch(config-port-prof)# speed 10000 switch(config-port-prof)#

Modifying a Port Profile

You can modify a port profile in port-profile configuration mode.

You can remove commands from a port profile using the no form of the command. When you remove a command from the port profile, the corresponding command is removed from the interface that is attached to the port profile.

Procedure

 

Command or Action

Purpose

Step 1

configure terminal

Enters configuration mode.

 

Example:

 

 

switch# configure terminal

 

 

switch(config)#

 

Step 2

port-profile [type {ethernet interface-vlan

 

port channel}] name

Example:

switch(config)# port-profile type ethernet test

switch(config-port-prof)#

Enters the port profile configuration mode for the specified port profile and allows you to add or remove configurations to the profile.

Step 3

exit

Exits the port profile configuration mode.

 

Example:

 

 

switch(config-port-prof)# exit

 

 

switch(config)#

 

Step 4

show port-profile

(Optional)

 

 

Displays the port profile configuration.

 

Example:

 

 

switch(config)# show port-profile name

 

Step 5

copy running-config startup-config

Example:

switch(config)# copy running-config startup-config

(Optional)

Copies the running configuration to the startup configuration.

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.
