Configuring the vPC Peer Switch

Configuring the vPC Peer Switch

Configuring a Pure vPC Peer Switch Topology

You can configure a pure vPC peer switch topology using the peer-switchcommand and then you set the best possible (lowest) spanning tree bridge priority value.

Note The values you apply for the spanning tree priority must be identical on both vPC peers.

Before You Begin

Ensure that you have enabled the vPC feature.

Procedure

 

Command or Action

Purpose

Step 1

switch# configure terminal

Enters global configuration mode.

Step 2

switch(config)# vpc domain

Enters the vPC domain number that you want to configure.

 

domain-id

The system enters the vpc-domain configuration mode.

Step 3

switch(config-vpc-domain)#

Enables the vPC switch pair to appear as a single STP root

 

peer-switch

in the Layer 2 topology.

 

 

Use the no form of the command to disable the peer switch

 

 

vPC topology.

Step 4

switch(config-vpc-domain)#

 

spanning-tree vlan vlan-range

 

priority value

Configures the bridge priority of the VLAN. Valid values are multiples of 4096. The default value is 32768.

Note This value must be identical on both vPC peers.

Step 5

switch(config-vpn-domain)# exit

Exits the vpc-domain configuration mode.

Step 6

switch(config)# show spanning-tree

(Optional)

 

summary

Displays a summary of the spanning tree port states

 

 

including the vPC peer switch.

 

 

Look for the following line in the command output:

 

 

vPC peer-switch is enabled (operational)

Step 7

switch(config)# copy

(Optional)

 

running-config startup-config

Saves the change persistently through reboots and restarts

 

 

by copying 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.
