AT-8700XL Series Switch User Guide

Upgrading Switch Software

When you first start the switch, it automatically loads the software release from FLASH memory into RAM, where the CPU uses it to run all the switch’s software features. The switch may also load a patch file to improve the main release. The software release and any patch files are current when the switch is produced at the factory.

When Allied Telesyn makes a new patch or release available, you may want to upgrade the software on your switch to use a new patch or release file. You can download the latest software patches, full software releases, and CLI help files from the website at: http://www.alliedtelesyn.co.nz/support/at8700xl.

Make sure you download a patch or release file that matches your switch model. A patch or release file for an AT-8700XL Series Switch has 87 as the first two digits of the filename. Patch files have the file extension .paz and release files have the file extension .rez. For example, the Software Release 2.6.1 for the AT-8700XL has the filename 87-261.rez.

Release and patch files are compressed ASCII files, and consist of a header followed by a sequence of Motorola S-records containing the actual code for the release or patch. The header has a standard format, which provides information about the release or patch to the switch.

Do not change the header in a release or patch file. At best, this will cause the file load or install to fail, at worst the switch could be put into a state where it will not boot correctly until field service action is taken.

The current release and patch file are set as the preferred install. The switch also has a very limited version of the software stored in permanent memory (EPROM). You cannot delete this version as it is the default, or boot install.

When you load a new software release or patch, you can set it to run once, the next time the switch reboots. This temporary install allows you to test run a new release or patch once, before you make it the preferred install. If the temporary install fails the switch will automatically run the preferred install if there is one, or otherwise the default install, the next time the switch reboots.

When the switch reboots, it checks the install information in a strict order:

Firstly, the switch checks the temporary install. If a temporary install is specified, the switch loads it into RAM and runs it. At the same time, it deletes the temporary install information so it will not load a second time. This information is deleted even if the temporary install triggers a fatal condition causing the switch to reboot immediately.

Secondly, if no temporary install is defined, or the install information is invalid, the switch checks the preferred install. If present, this install is loaded. The switch never deletes the preferred install information.

Thirdly, if neither a temporary install nor a preferred install is specified, the switch loads the default install. The default install is always present in the switch because if, for some reason, it is not, the INSTALL module will restore it.

The preferred install should not be set up with an untested release or patch. It is advisable to install new releases or patches as the temporary install, and when the switch boots correctly, to then set up the preferred install with the new release or patch.

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.
