Configuring Layer 3 Interfaces

Verifying the Layer 3 Interfaces Configuration

 

Command or Action

Purpose

Step 3

switch(conifg-if)#vrf member vrf-name

Adds this interface to a VRF.

Step 4

switch(config-if)# [ip

Configures an IP address for this interface. You

 

ipv6]ip-address/length

must do this step after you assign this interface

 

 

to a VRF.

Step 5

switch(config-if)# show vrf [vrf-name]

(Optional)

 

interface interface-type number

Displays VRF information.

Step 6

switch(config-if)# show interfaces

(Optional)

 

 

Displays the Layer 3 interface statistics.

Step 7

switch(config-if)# copy running-config

(Optional)

 

startup-config

Saves the change persistently through reboots

 

 

and restarts by copying the running configuration

 

 

to the startup configuration.

This example shows how to add a Layer 3 interface to the VRF:

switch# configure terminal switch(config)# interface loopback 0 switch(config-if)# vrf member RemoteOfficeVRF switch(config-if)# ip address 209.0.2.1/16 switch(config-if)# copy running-config startup-config

Verifying the Layer 3 Interfaces Configuration

Use one of the following commands to verify the configuration:

Command

Purpose

show interface ethernet slot/port

and counters (including the 5-minute exponentially

 

decayed moving average of inbound and outbound

 

packet and byte rates).

show interface ethernet slot/port brief

Displays the Layer 3 interface operational status.

show interface ethernet slot/port capabilities

Displays the Layer 3 interface capabilities, including

 

port type, speed, and duplex.

show interface ethernet slot/port description

Displays the Layer 3 interface description.

show interface ethernet slot/port status

Displays the Layer 3 interface administrative status,

 

port mode, speed, and duplex.

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.
