Switching

This section outlines the Layer 2 and IP switching features on the switch, and how to configure some of them. For more detail, refer to the Switching and Internet Protocol (IP) chapters in the AT-8700XL Series Switch Software Reference.

Switch Ports

Each switch port is uniquely identified by a port number. The switch supports a number of features at the physical level that allow it to be connected in a variety of physical networks. This physical layer (layer 1) versatility includes:

Enabling and disabling of ports.

Auto negotiation of port speed and duplex mode for all 10/100 BASE ports.

Manual setting of port speed and duplex mode for all 10/100 BASE ports.

Link up and link down triggers.

Port trunking.

Packet storm protection.

Port mirroring.

Support for SNMP management

Enabling and Disabling Switch Ports

An switch port that is enabled is available for packet reception and transmission. Its administrative status in the Interfaces MIB is UP. Disabling a switch port does not affect the STP operation on the port. Enabling a switch port will allow the port to participate in spanning tree negotiation. A switch port that has been disabled by the Port Security feature cannot be enabled using the ENABLE SWITCH PORT command.

To enable or disable a switch port, use the commands:

ENABLE SWITCH PORT={port-listALL}

DISABLE SWITCH PORT={port-listALL}

at-8700xl series switch specifications

Allied Telesis AT-8700XL Series Switches are sophisticated networking devices designed to meet the demanding requirements of modern enterprise environments. These managed Ethernet switches are optimized for reliability, performance, and scalability, making them ideal for various applications, from small businesses to large-scale networks.

One of the standout features of the AT-8700XL series is its robust Layer 2 and Layer 3 capabilities. This versatility allows the switches to perform both basic switching and advanced routing functions, facilitating efficient data traffic management. The series supports a wide range of standard protocols, including VLANs, STP, and RSTP, ensuring smooth and flexible network segmentation.

Another critical characteristic is the series' high-speed connectivity options. With multiple Gigabit Ethernet ports, the AT-8700XL series can handle significant data loads, ensuring seamless communication between connected devices. Furthermore, some models within the series offer 10 Gigabit uplink ports, providing the necessary bandwidth to connect to core networks or high-speed servers.

The AT-8700XL series incorporates advanced Quality of Service (QoS) features that enable network administrators to prioritize traffic effectively. This is particularly crucial for applications sensitive to latency, such as VoIP and video conferencing. By ensuring that time-sensitive data packets are transmitted promptly, the switches help maintain optimal performance across the entire network.

Power over Ethernet (PoE) support is yet another advantage of the AT-8700XL series. This feature allows the switches to deliver power to connected devices, such as IP cameras and wireless access points, via the Ethernet cable. This capability simplifies installations by reducing the need for additional power sources, ultimately saving on costs and improving efficiency.

Security is paramount in any network, and the AT-8700XL series does not disappoint. The switches employ robust security protocols, including Access Control Lists (ACLs), MAC address filtering, and DHCP snooping, to protect against unauthorized access and ensure network integrity.

In summary, Allied Telesis AT-8700XL Series Switches offer a comprehensive solution for various networking needs. With their Layer 2 and Layer 3 capabilities, high-speed connectivity, QoS features, PoE support, and security measures, these switches are well-equipped to enhance network efficiency and reliability, making them an excellent choice for organizations looking to future-proof their infrastructure. The AT-8700XL series exemplifies Allied Telesis's commitment to delivering high-quality networking solutions that cater to the evolving demands of businesses today.
