sFlow Collectors

Guidelines

AlliedWare Plus Version 2.1.2 Management Software Web Browser User’s Guide

To configure the agent to forward these port statistics to the collectors, you have to specify polling rates, which define the maximum amount of time permitted between successive queries of the counters of a port by the agent.

Different ports can have different polling rates. Ports to which critical network devices are connected can be assigned low polling rates, so that the information on the collector is kept up-to-date. Ports connected to less critical devices can be assigned higher polling rates.

To increase its efficiency, the agent can send port status and counter information before the polling interval of a port times out. For example, if you define a polling interval of five minutes for a port, the agent, depending on its internal dynamics, may send the information to the collector before five minutes have actually elapsed.

The sFlow agent on the switch can send port performance data to up to an sFlow collector on your network. The performance data from each port can be sent to one collector.

Here are the guidelines for the sFlow agent:

The sFlow agent can send port performance data to up to four sFlow collectors on your network.

The switch must have a management IP address. For instructions, refer to Chapter 17, “Setting IPv4 and IPv6 Management” on page 187.

The sFlow collectors must be members of the same subnet as the management IP address of the switch, or must have access to it through routers or other Layer 3 devices.

If the sFlow collectors are not a member of the same subnet as the management IP address of the switch, the switch must have a default gateway that specifies the first hop to reaching the collectors’ subnet. For instructions, refer to Chapter 17, “Setting IPv4 and IPv6 Management” on page 187.

The sFlow feature is not dependent on SNMP. You do not have to enable or configure SNMP on the switch to use the sFlow feature. In addition, you cannot use sFlow collectors to configure or manage SNMP.

This allows for flexible network configuration and scalability, accommodating both wired and wireless devices efficiently. The switch also supports auto-negotiation and auto-MDI/MDI-X, which simplifies installation and connectivity by automatically detecting and configuring the appropriate settings.

The AT-9000/28 employs advanced switching technologies, such as IEEE 802.1Q VLAN tagging, which enables the segregation of traffic for improved security and performance. This feature is crucial for businesses that require data isolation between different departments or user groups. In addition, the switch supports quality of service (QoS) protocols, allowing for traffic prioritization. This is particularly beneficial for organizations that handle multimedia applications or VoIP services that demand reliable bandwidth.

Another significant characteristic of the AT-9000/28 is its support for port mirroring. This capability is essential for network monitoring and troubleshooting, as it allows administrators to track and analyze network traffic efficiently. Furthermore, the switch supports multiple user authentication methods, including RADIUS and TACACS+, thus enhancing network security.

The AT-9000/28 is built with energy efficiency in mind, featuring Energy Efficient Ethernet (EEE) technology. This reduces power consumption during periods of low traffic without compromising performance, which aids in lowering overall operational costs.

In terms of management, the AT-9000/28 offers versatile management options, including a web-based GUI, Command Line Interface (CLI), and SNMP support. This flexibility enables network administrators to configure, monitor, and troubleshoot the switch easily.

Overall, the Allied Telesis AT-9000/28 is a reliable switch well-suited for a variety of network environments. Its combination of performance, security features, and energy efficiency makes it an excellent choice for organizations looking to optimize their network infrastructure. With robust capabilities and advanced technologies, the AT-9000/28 stands out as a valuable addition to any networking setup.
