Configuring Port Channels

Verifying the Load-Balancing Outgoing Port ID

Command

Purpose

switch# show port-channel summary

Displays a summary for the port channel interfaces.

switch# show port-channel traffic

Displays the traffic statistics for port channels.

switch# show port-channel usage

Displays the range of used and unused channel

 

numbers.

switch# show port-channel database

Displays information on current running of the port

 

channel feature.

switch# show port-channel load-balance

Displays information about load-balancing using port

 

channels.

Verifying the Load-Balancing Outgoing Port ID

Command Guidelines

The show port-channelload-balancecommand allows you to verify which ports a given frame is hashed to on a port channel. You need to specify the VLAN and the destination MAC in order to get accurate results.

Note Certain traffic flows are not subject to hashing, for example when there is a single port in a port-channel.

To display the load-balancing outgoing port ID, perform one of the tasks listed in the table below.

Command

Purpose

switch# show port-channel load-balance

Displays the outgoing port ID.

Example

This example shows the output of the short port-channelload-balancecommand.

switch# show port-channel load-balance forwarding-path interface port-channel 10 vlan 1 dst-ip 1.225.225.225 src-ip 1.1.10.10 src-mac aa:bb:cc:dd:ee:ff

Missing params will be substituted by 0's. Load-balance Algorithm on switch: source-dest-port crc8_hash:204 Outgoing port id: Ethernet 1/1 Param(s) used to calculate load balance: dst-port: 0

src-port: 0

dst-ip: 1.225.225.225

src-ip: 1.1.10.10

dst-mac: 0000.0000.0000

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.
