Configuring Virtual Port Channels

Moving Other Port Channels into a vPC

You must configure both switches on either side of the vPC peer link with the following procedure.

Procedure

 

Command or Action

Purpose

Step 1

switch# configure terminal

Enters configuration mode.

Step 2

switch(config)# interface ethernet

Specifies an interface to configure, and enters

 

chassis/slot/port

interface configuration mode.

Step 3

switch(config-if)# channel-group

Creates an EtherChannel host interface on the

 

channel-numbermode {active passive

selected host interface.

 

on}

 

Step 4

switch# show port-channel summary

(Optional)

 

 

Displays information about each EtherChannel

 

 

host interface.

Step 5

switch# copy running-config

(Optional)

 

startup-config

Copies the running configuration to the startup

 

 

configuration.

This example shows how to configure an EtherChannel host interface:

switch# configure terminal

switch(config)# interface ethernet 101/1/20 switch(config-if)#channel-group 7 mode active

Moving Other Port Channels into a vPC

Before You Begin

Ensure that you have enabled the vPC feature.

You must configure both switches on either side of the vPC peer link with the following procedure.

Procedure

 

Command or Action

Purpose

 

Step 1

switch# configure terminal

Enters configuration mode.

Step 2

switch(config)# interface

Selects the port channel that you want to put into the vPC to

 

port-channelchannel-number

connect to the downstream switch, and enters the interface

 

 

configuration mode.

 

 

Note

A vPC can be configured on a normal port channel

 

 

 

(physical vPC topology), on an port channel fabric

interface (fabric extender vPC topology), and on an port channel host interface (host interface vPC topology)

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.
