New features in this release - The version 2.69 agent feature set is a compatible superset of that provided by all previous versions of this agent. This agent adds support for enhancements and known faults as described in section 4 and section 6 below It provides support for the following SuperStack 610/630/1100/3300 family switches: Switch 610 3C16954 Switch 630 3C16984 Switch 1100-12 3C16951 Switch 1100-24 3C16950 Switch 3300-12 3C16981 and 3C16981A Switch 3300-24 3C16980 and 3C16980A Switch 3300 FX 3C16982 Switch 3300 MM 3C16988 and 3C16988A Switch 3300 SM 3C16987 and 3C16987A Switch 3300 TM 3C16986 and 3C16986A Switch 3300 XM 3C16985, 3C16985A and 3C16985B AUI Transceiver Interface Module (F) 3C12060 SMA Transceiver Interface Module 3C12061 TP Transceiver Interface Module 3C12063 AUI Transceiver Interface Module (M) 3C12064 10BASE-FL Transceiver Interface Module 3C12065 Coaxial Transceiver Module 3C12066 10BASE-FB Transceiver Interface Module 3C12067 Matrix Module 3C16960 Matrix Cable 3C16965 Layer 3 Module 3C16968 100BASE-FX Fibre Module 3C16970 100BASE-FX Dual Fibre Module 3C16971 1000BASE-LX Module 3C16973 1000BASE-SX Module 3C16975 ATM Downlink Module 3C16977 1000BASE-T Module 3C16978 ________________________________________________________________________________ 3. Information about other 3Com products affected - This agent can also be downloaded on to IBM Nways Switches 8271-E12/24 and 8271-F12/24 and will operate as before with an IBM Network Management application. If the customer so wishes, using a simple conversion command, an Nways switch can be made to operate as a 3Com switch when accessed by the Network Management application. Conversely, a 3Com switch can be set to operate as an Nways switch should the customer require this for it to operate with an IBM Network Management facility. Thus switches can be customised to suit the customers' preferred Network Management tool. NOTE: The user must rename the download file from s2s02_69.bin to nws02_69.bin when downloading the agent to an Nways switch for the very first time. For details on how to perform this customisation please contact 3Com support. ________________________________________________________________________________ 4. Fixes for known faults - This version of code implements changes to memory allocation within the switch and may significantly improve data throughput and switch reliability. Whilst this new release of code can be applied to any SuperStack switch from the 1100 or 3300 families, 3Com particularly recommends this software upgrade for the following products: SuperStack II Switch 1100 12 port - 3C16951 (serial number prefixes up to and including 0400) SuperStack II Switch 1100 24 port - 3C16950 (serial number prefixes up to and including 0400) SuperStack II Switch 3300 12 port - 3C16981 SuperStack II Switch 3300 24 port - 3C16980 SuperStack II Switch 3300 XM - 3C16985 SuperStack II Switch 3300 FX 8 port - 3C16982 (serial number prefixes up to and including 0400) SuperStack II Switch 610 24 port - 3C16954 SuperStack II Switch 630 24 port - 3C16984 SuperStack 3 Switch 3300 24 port - 3C16980A (0100 serial number prefix only). SuperStack 3 Switch 3300 12 port - 3C16981A (0100 serial number prefix only). or any SuperStack II or 3 Switch containing one of the following modules: SuperStack II Single 100 Base FX modules for 1100/3300 family - 3C16970 SuperStack II Dual 100 Base FX modules for 1100/3300 family - 3C16971 SuperStack II Layer 3 Module - 3C16968 If a switch is suspected to be faulty, it should be upgraded to v2.69 and re-tested before being returned to 3Com for repair. If it is not possible to upgrade using the normal TFTP process, 3Com recommend that the Software Upgrade Utility (available to download from the 3Com website) is used. In many cases it is possible to upgrade a unit using the Software Upgrade Utility when a TFTP upgrade has proved impossible. ________________________________________________________________________________ 5. Recommendations when using this release - It is strongly recommended that all switches in a stack should be running the same version of agent software. If you add any of the above switches to an existing Switch 1100/3300 stack, you will need to install the version 2.69 agent on the existing switches for the stack to run properly. - Following a TFTP upgrade on a stack of switches, it is recommended that a reset is performed to ensure that VLAN information is consistent across the stack. - If you use: - a 1000BASE-SX Module or 1000BASE-LX Module in any of the switches or - a Switch 3300 SM and you connect to another 1000BASE-SX or 1000BASE-LX device, 3Com recommends that both ends of the link are configured to use the same IEEE 802.3z auto-negotiation setting. - The Port Set-up page of the web interface contains an Auto-negotiation listbox that allows you to manage auto-negotiation for twisted-pair ports. - If you set the Auto-negotiation listbox to Enabled and click Apply, the true speed and duplex settings may not be shown immediately on the Port Set-up page. We recommend that you click the relevant port icon on the switch graphic to refresh the page and show the true settings. - If you have a CoreBuilder 3500 Layer 3 switch on your network, we recommend that the CoreBuilder 3500 has management software version 2.0x or later installed. - If an existing stack with Spanning Tree enabled is powered-up with a new switch that has Spanning Tree disabled, the setting of the new switch may override the whole stack. A similar issue may also be encountered with the Broadcast Storm control setting. When powering up an existing stack with new switches in this way, the recommended procedure is to either (i) configure the new switch appropriately before adding it to the stack, or (ii) re-configure the new stack appropriately immediately after power-up - Immediately after creating a new VLAN, the VLAN based counters will only count for ports local to the switch where the VLAN was created. In order for ports in other switches to contribute to the VLAN counters a reset of the stack is required. - If a layer 3 expansion module is located in a switch and the switch has a default IP address of 0.0.0.0, spurious messages may be sent out on any slip connection that may be established with that switch. If this happens, use the CLI through the serial port to reconfigure the IP address for the switches ________________________________________________________________________________ 6. Known problems with this release Version 2.69 is distributed with the following known problems: - If you use: - a 1000BASE-SX Module or 1000BASE-LX Module in any of the switches or - a Switch 3300 SM ensure that the optical connection to the port conforms to IEEE 802.3z. If the levels are outside the IEEE 802.3z standard, the switch may not operate correctly. - (Switch 610 and 1100 only) The 10BASE-T/100BASE-TX ports on your switch cannot auto-negotiate IEEE 802.3x flow control. If you want to enable IEEE 802.3x flow control on a 10BASE-T/100BASE-TX port: 1. From the Port Set-up page of the web interface, set the Auto-negotiation listbox to Disabled. 2. Click Apply. 3. Set the FD Flow Control listbox to Enabled. 4. Configure the port to the desired speed and full duplex operation. 5. Click Apply. - Packets that have an IEEE 802.1Q tag can have a legal length of up to 1522 bytes. RMON categorises packets over 1518 bytes as oversize packets, which means that some 802.1Q-tagged packets may be recorded as oversize. - Roving analysis generates up to two copies of each flooded packet. To avoid this duplication, remove the analysis port from all the VLANs to which the monitor port belongs. If you do this, the analysis port generates all VLAN-tagged packets as untagged packets. - If you are using a SuperStack II Switch 1000BASE-SX/LX Module or a 3300SM and you configure Link Up traps for the Module port, some of the traps may not be generated. To ensure that Link Up traps always reach your management workstation, configure the traps on both ends of the link. - IEEE 802.1Q VLAN Learning (GVRP) only functions correctly in networks that have 16 or less 802.1Q VLANs. - After BOOTP is enabled the switch needs to be power cycled before BOOTP will start operating. - If the ATM or Layer 3 expansion module is configured with the same IP address as the switch stack, the whole stack may become unmanageable. If this scenario occurs then the CLI may be used through a serial connection to change the IP address of the switch or expansion module. - When accessing the switch using Netscape version 6, the java graphs in the health section of the web interface will not display. This is a Netscape 6 /Mozilla problem and is recorded in one of their fault reports. http://bugzilla.mozilla.org/show_bug.cgi?id=60422. ________________________________________________________________________________ 7. Documentation errors and omissions SuperStack Switch Management Guide (DUA1695-0BAA05) Management Software Version 2.60 - Chapter 1 Table 3 Software Features (page 20) "No. of MAC Addresses supported - Up to 6,000" also applies to the switches: Switch 3300 MM 3C16988 and 3C16988A Switch 3300 SM 3C16987 and 3C16987A Switch 3300 TM 3C16986 and 3C16986A Switch 3300 XM 3C16985A and 3C16985B - Chapter 1 Roving Analysis, Chapter 3 What is Roving Analysis? (page 28, 87) Please note that reconfiguration of Roving Analysis is required in the event of any power interruption or stack change. Examples of such events are a power cycle; a software agent upgrade; a CLI, web or SNMP reset; or a communication loss to a switch in the stack. - Chapter 3 (page 72) No. of MAC Addresses supported - Up to 6,000" also applies to the switches: Switch 3300 MM 3C16988 and 3C16988A Switch 3300 SM 3C16987 and 3C16987A Switch 3300 TM 3C16986 and 3C16986A Switch 3300 XM 3C16985A and 3C16985B - Chapter 5 Port Trunks, Correction to information point at the bottom of the page 158. Only one port trunk is supported per switch, if that unit is fitted with a gigabit module (1000BASE-LX 3C16973/ 1000BASE-SX 3C16975/ 1000BASE-T 3C16978) or an ATM Downlink Module (3C16977) or has a gigabit interface (Switch 3300 SM 3C16987/3C16987A Switch 3300 TM 3C16986/3C16986A) - Appendix B (page 231) Management Upgrade Utility You may see references to the Serial Update Utility in some of the documentation supplied with the Super-Stack Switch Series CD-ROM. This utility is referred to as the Management Software Upgrade Utility in the Management Guide. The two terms refer to the same utility. ________________________________________________________________________________ 8.

Upgrading this release The management software can be upgraded by using a TFTP Server, by using the Serial Update Utility or by using the Software Update Utility supplied with your switch. - If you have downloaded the management software designed for a TFTP Server upgrade, place the file s2s02_69.bin in the appropriate directory on the Server. It is advised that TFTP upgrades should be performed using a local TFTP server. - A power interrupt during software upgrade may cause a corrupted agent image on the switch. If this occurs then subsequent rebooting of the switch will be unsuccessful. The front panel LEDs 2 and 3 will be lit and the power LED will flash. In this event the software agent should be upgraded via a serial upgrade. For more information, refer to the Management Guide supplied with your switch. - If you have downloaded the management software designed for a serial upgrade using the Software Update Utility, place the file s2s02_69.bin in a directory accessible by the PC running the utility. For more information, refer to the release note supplied with your switch. - The Software Update Utility is a Windows application used to serially update the software to the switch via the console port. It is variously referred to in the documentation that accompanies your Switch as: Serial Update Utility, Serial Upgrade Utility, Software Update Utility, Agent Update Utility and Management Upgrade Utility. - If you have downloaded the management software designed for a serial upgrade using the Serial Update Utility, place the file s2s02_69.bin in a directory accessible by the PC running the utility. For more information, refer to the Management Guide supplied with your switch. - The Serial Update Utility operates on a PC running the DOS operating system or in a DOS box running under Windows 95/98. The utility may not operate correctly in a DOS box running under Windows 2000 or in other operating system environments. - Software upgrades initiated from the CLI or WEB of 2.69 and subsequent agents, now benefit from progress feed back. Before starting the upgrade the switch now verifies that the file specified can be obtained from the given IP address, and is a valid agent for the device. If this verification fails, error messages will be reported, otherwise it will indicate that the upgrade is to begin before the switch resets and the upgrade proceeds. - If your TFTP server reports information about each file transfer, it will show three requests for the upgrade file each time a switch in the stack upgrades. The first two will be terminated with the message "Aborted by client request" This is the normal operation of the upgrade process and does not indicate an error. ________________________________________________________________________________ 10. 3Com's World Wide Web site Access the latest networking information on the 3Com Corporation World Wide Web site by entering our URL into your Internet browser: http://www.3com.com/ ________________________________________________________________________________ (R) means registered trademark. 3Com and SuperStack are registered trademarks of 3Com Corporation.
