PN 613-50389-00 Rev A 9 Allied Telesyn, Inc.
• Statistics for an AT-8024GB
The statistics counters for an AT-8024GB switch displayed incorrect values. This problem
has been resolved.
• Port 1 in a Port Trunk
You could not delete Port 1 from a port trunk. This problem has been resolved.
• STP and RSTP Port Costs for an AT-8024M
The management software periodically assigned incorrect default STP and RSTP port
costs to ports on expansion modules. This problem has been resolved.
• Port Configuration
The switch would periodically lose port configuration when reset or power cycled. This
problem has been resolved.
Operational Notes
• Command Line Interface and Web Browser Management
The command line interface is not available from a web browser management session.
The command line interface is available from a local or a Telnet management session.
• MDI Port Setting
You must set a port’s MDI setting whenever you manually set a port’s speed or duplex
mode. The Auto-MDI setting is available only when a port is auto-negotiating speed and
duplex mode, and not when a port is configured manually. The default setting is MDI-X for
a manually configured port.
• Default Subnet Mask
The default subnet mask has been changed from 255.255.0.0 to 0.0.0.0.
• Boot Prompt Message
During boot up, the switch displays the following prompt:
Press any key to stop image loading and go to Boot Prompt.
This prompt is intended for manufacturing purposes only. If you do inadvertently display
the boot prompt (=>), type boot and press Return to start the switch’s software.
• GBIC Modules
You cannot configure a GBIC slot if no GBIC module is installed.
• 10 Mbps, Half-duplex Mode End Nodes
The switch may not Auto-Negotiate correctly with some 10 Mbps, half-duplex mode
end nodes. This problem can result in poor network performance. You can resolve this
problem by manually configuring to 10 Mbps, half-duplex mode those switch ports that
are connected to end nodes operating at that speed and duplex mode.
