Configuring Port Channels

Verifying Port Channel Configuration

 

Command or Action

Purpose

Step 4

lacp graceful-convergence

Enables LACP graceful convergence on the

 

 

specified port channel.

 

Example:

 

 

switch(config-if)# lacp

 

 

graceful-convergence

 

 

switch(config-if) #

 

Step 5

no shutdown

Administratively brings the port channel up.

 

Example:

 

 

switch(config-if)# no shutdown

 

 

switch(config-if) #

 

Step 6

copy running-config startup-config

Example:

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

(Optional)

Saves the change persistently through reboots and restarts by copying the running configuration to the startup configuration.

The following example disables LACP graceful convergence on a port channel:

switch# configure terminal switch(config) # interface port-channel 1 switch(config-if) # shutdown switch(config-if) # lacp graceful-convergenceswitch(config-if) # no shutdown switch(config-if) #

Verifying Port Channel Configuration

To display port channel configuration information, perform one of the following tasks:

Command

switch# show interface port-channel channel-number

switch# show feature

switch# show resource

switch# show lacp {counters interface type slot/port neighbor port-channel system-identifier}

switch# show port-channel compatibility-parameters

switch# show port-channel database [interface port-channel channel-number]

Purpose

Displays the status of a port channel interface.

Displays enabled features.

Displays the number of resources currently available in the system.

Displays LACP information.

Displays the parameters that must be the same among the member ports in order to join a port channel.

Displays the aggregation state for one or more port-channel interfaces.

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.
