Configuring SNMP

SNMP Overview

SNMP Overview

Simple Network Management Protocol (SNMP) provides a method for managing network devices. Equipment commonly managed with SNMP includes switches, routers and host computers. SNMP is typically used to configure these devices for proper operation in a network environment, as well as to monitor them to evaluate performance or detect potential problems.

Managed devices supporting SNMP contain software, which runs locally on the device and is referred to as an agent. A defined set of variables, known as managed objects, is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB) that provides a standard presentation of the information controlled by the agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network.

The switch includes an onboard agent that supports SNMP versions 1, 2c, and 3. This agent continuously monitors the status of the switch hardware, as well as the traffic passing through its ports. Access to the onboard agent using SNMP v1 and v2c is controlled by community strings. To communicate with the switch, the management station must first submit a valid community string for authentication.

Access to the switch using SNMPv3 provides additional security features that cover message integrity, authentication, and encryption; as well as controlling user access to specific areas of the MIB tree.

The SNMPv3 security structure consists of security models, with each model having its own security levels. There are three security models defined, SNMPv1, SNMPv2c, and SNMPv3. Users are assigned to “groups” that are defined by a security model and specified security levels. Each group also has a defined security access to set of MIB objects for reading and writing, which are known as “views.”

The device has a default view (all MIB objects) and default groups defined for security models v1 and v2c. The following table shows the security models and levels available and the system default settings.

The SNMP agents maintain a list of variables, which are used to manage the device. The variables are defined in the Management Information Base (MIB). The SNMP agent defines the MIB specification format, as well as the format used to access the information over the network. Access rights to the SNMP agents are controlled by access strings.

The device is SNMP-compliant and contains an SNMP agent that supports a set of standard and private MIB variables. Developers of management stations require the exact structure of the MIB tree and receive the complete private MIBs information before being able to manage the MIBs.

All parameters are manageable from any SNMP management platform, except the SNMP management station IP address and community (community name and access rights). The SNMP management access to the device is disabled if no community strings exist.

Notes

•The device switch is delivered with no community strings configured.

•The device generates copy traps.

AT-8000S specifications

The Allied Telesis AT-8000S series switches are a range of advanced Layer 2 Ethernet switches designed for efficient networking in various environments. Engineered with performance, reliability, and cost-effectiveness in mind, these switches are ideal for businesses seeking to enhance their network infrastructure.

One of the main features of the AT-8000S series is its high-speed data forwarding capabilities. With support for 10/100/1000 Mbps Ethernet ports, these switches provide fast and reliable connections, enabling seamless data transfer and enhanced communication between devices. The non-blocking switching architecture ensures that full bandwidth is available at all times, maximizing throughput and reducing latency in network traffic.

The AT-8000S series incorporates advanced Layer 2 switching technologies, such as VLAN support, allowing users to segment network traffic for improved performance and security. Virtual Local Area Networks (VLANs) help isolate sensitive data and reduce unnecessary broadcast traffic, enhancing the overall performance of the network.

Quality of Service (QoS) is another significant feature integrated into these switches, prioritizing different classes of network traffic. This functionality ensures that critical applications receive the necessary bandwidth and minimal latency, which is imperative for voice over IP, video conferencing, and other latency-sensitive applications.

In terms of network management, the AT-8000S series provides a variety of options, including an intuitive web-based interface, SNMP support, and the ability to manage switch configurations through console access. This flexibility allows network administrators to monitor performance and manage configurations easily.

The switches are built for durability, featuring a robust design suitable for deployment in various environments, including temperature-sensitive areas. Power over Ethernet (PoE) capability is also available in certain models, allowing network devices like IP cameras and wireless access points to receive power through the same cable as data, simplifying installation and reducing clutter.

Allied Telesis emphasizes security within the AT-8000S series, with features such as port security, DHCP snooping, and IEEE 802.1X authentication to safeguard against unauthorized access and potential threats.

Overall, the Allied Telesis AT-8000S series provides a comprehensive networking solution tailored for modern business needs, combining performance, flexibility, and security to support a growing array of applications and devices within the network.
