Viewing The Graceful Type-1 Check Status

Command

Purpose

 

switch# show feature

Displays whether vPC is enabled or not.

switch# show port-channel capacity

Displays how many EtherChannels are configured

 

and how many are still available on the switch.

switch# show running-config vpc

Displays running configuration information for vPCs.

switch# show vpc brief

Displays brief information on the vPCs.

switch# show vpc consistency-parameters

Displays the status of those parameters that must be

 

consistent across all vPC interfaces.

switch# show vpc peer-keepalive

Displays information on the peer-keepalive messages.

switch# show vpc role

Displays the peer status, the role of the local switch,

 

the vPC system MAC address and system priority,

 

and the MAC address and priority for the local vPC

 

switch.

 

switch# show vpc statistics

Displays statistics on the vPCs.

 

Note

This command displays the vPC statistics

 

 

only for the vPC peer device that you are

 

 

working on.

For information about the switch output, see the Command Reference for your Cisco Nexus Series switch.

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.
