Chapter 6

Maintenance and Troubleshooting

This Chapter

If you are familiar with networking and switch operations, you may be able to diagnose and solve some problems yourself.

This chapter gives tips on how to:

■start your switch (see “How the Switch Starts Up” on page 74).

■avoid problems (see “How to Avoid Problems” on page 75).

■reconfigure your switch if you accidentally clear the FLASH memory (see “What to Do if You Clear FLASH Memory Completely” on page 77).

■reset passwords if they are lost (see “What to Do if Passwords are Lost” on page 78).

■gather information from your switch that support personnel need to provide accurate support tailored to your situation (see “Getting the Most Out of Technical Support” on page 78).

■restart the switch at any time with no configuration (see “Resetting Switch Defaults” on page 79).

■check whether there is a connection between the switch and another routing interface in the network (see “Checking Connections Using PING” on page 79).

■troubleshoot problems with DHCP IP addresses if the switch is acting as a client or as a server (see “Troubleshooting DHCP IP Addresses” on page 81)

■examine the route that packets pass between two systems running the IP protocol (see “Using Trace Route for IP Traffic” on page 81).

Information gained from the LEDs on the front panel of the switch is described in the AT-8700XL Series Hardware Reference.

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.
