Upgrading a Switch
This release of the management software consists of the following two files: • ATS39.img — New AT-S39 management image file
• ATS39.ldr — New boot loader
Allied Telesyn recommends downloading both files when upgrading a switch. The files should be downloaded in the following order:
• ATS39.img — Follow the procedure in Chapter 16 of the AT-S39 Version 1.1 User’s Guide
to download the new version onto the switch. It is recommended that you load the new software image from a local management session. (To load the new software image using TFTP, you must first load the AT-S39 V1.1 Patch onto the switch. The patch can be down-loaded from a local management session or with TFTP.)
new management software is installed.
AT-S39 Version 1.3 New Features
• Auto-detection on the RS232 Terminal Port
The new AT-S39 boot loader (Version 1.1) provides the switch with an auto-detect feature that allows it to automatically determine the speed of a terminal connected to the RS232 Terminal Port. This feature simplifies the task of starting a local management session. Pressing any key on your keyboard within five seconds after powering on or resetting the switch activates the feature. The switch responds by automatically determining the speed of the terminal and configuring the speed of the RS232 Terminal Port. Otherwise, the switch uses a default baud rate of 115200 bits per second (bps). The switch maintains the terminal port speed until the system is powered on or reset. The range of the port’s baud rate is 1200 to 115200 bps. For information on how to start a local management session, refer to Chapter 2 in the AT-S39 Version 1.3 User’s Guide.
• Simplified Software Downloads through a Local Management Session
A new item has been added to the Administration menu to simplify the task of
downloading files, such as software images or configuration files, onto a switch from a local management session. The new Xmodem File Transfer menu selection eliminates the need for invalidating the current software image when installing new software. For further information on this feature, refer to Chapter 16 in the AT-S39 Version 1.3 User’s Guide. • Releasing an IP Address Issued by a DHCP Server
Another new item in the Administration menu is Release DHCP IP Address. This selection is useful if you configured the switch to obtain its IP address from a DHCP. Selecting the new menu option before resetting or powering off the unit prompts the switch to release its IP address back to the DHCP server for assignment to another network device.
• Configuring IGMP Snooping from a Web Browser Management Session
The web browser management interface now features a window for configuring IGMP snooping. For information on the new window, refer to Chapter 27 in the AT-S39 Version 1.3 User’s Guide.
Resolved Issues
• Telnet Management Session and Pinging over Subnets
Previous management software versions did not support managing a switch from a Telnet management session when the management workstation and the switch were on
different subnets. You also could not ping the switch from a workstation on a different subnet. Both issues have been resolved.
• Switch Management through a Tagged Port
The switch could not be managed from a Telnet or web browser management session if the remote workstation was communicating with the switch through a tagged port. You also could not ping a switch if the workstation was communicating through a tagged port. Both problems have been resolved.
• GBIC Auto-Negotiating
A GBIC module would periodically fail to auto-negotiate correctly with an end node. This problem has been resolved.
• GBIC Information Window
The GBIC Information window displayed incorrect information. This problem has been resolved.
• Port Configuration Window
The Port Configuration window periodically failed to display all menu options. This problem has been resolved.
Operational Notes
• Invalidate Software Image
The Invalidate Software Image in the Administration menu has been removed in version 1.3. The menu option, used to download new software images onto the switch, has been replaced with the new Xmodem File Transfer option. For information on how to download software onto the switch, refer to Chapter 16 in the AT-S39 Version 1.3 User’s Guide. • 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.
New Features
• SNMP
This version supports SNMP version 1 and version 2c. The software supports the following Management Information Bases (MIBs):
• SNMP MIB-II (RFC 1213) • Bridge MIB (RFC 1493)
• Interface Group MIB (RFC 1573) • Ethernet MIB (RFC 1643)
• Remote Network MIB (RFC 1757) • Allied Telesyn managed switch MIB • IGMP Snooping
This version supports IGMP snooping version 1 and version 2. The management software features auto-detection of multicast routers. Additionally, the software features menu options for listing multicast routers and host nodes.
• Web Browser Management
The network administrator can disable web browser management on a switch to increase switch security.
• Trivial File Transfer Protocol (TFTP)
This version supports the downloading of AT-S39 image files and switch configuration files using TFTP.
• AT-S39 Version Number and Switch Serial Number
The management software now features a new Diagnostics menu option that displays the following information:
• AT-S39 version • Switch serial number • Bootloader version • Switch MAC address
Resolved Issues
• Bridge Protocol Data Units (BPDUs)
The switch would drop tagged BPDUs. This problem has been resolved. • Port Status Window
The Port Status window would periodically display a port’s VLAN ID as “0”. This problem has been resolved.
• Spanning Tree Protocol (STP)
STP periodically failed to place ports of redundant paths into a blocking state, resulting in network loops. This problem has been resolved.
• VLAN Menus
