This agent adds support for the new 3com branding to the web and CLI management subsystems. It provides support for the following SuperStack 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 Switch 3300 XM 3C16985A and 3C16985B - Version 2.60 agent additionally adds support for enhancements and known faults as described in section 4 below. =============================================================================== 3: Using IBM Nways Switches 8271-E12/24 =============================================================================== - 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 unit when accessed by the Network Management application. Conversely, a 3Com unit 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 units can be customized to suit the customers' preferred Network Management tool. NOTE: The user must rename the download file from s2s02_60.bin to nws02_60.bin when downloading the agent to an Nways switch for the very first time. For details on how to perform this customization please contact 3Com support. =============================================================================== 4: Enhancements and Fixes for Known Faults =============================================================================== - Fix for Command Line Interface (CLI) routerPort addPort command not working on Switch 3300 XM (3C16985 and 3C16985A). - Fix for inablility in CLI to "Find or Add or Remove" MAC address in switch database when logged in as "manager". - Fix for Spanning Tree specific frames not being forwarded when Spanning Tree is disabled. =============================================================================== 5: Recommendations When Using This Release =============================================================================== - It is strongly recommended that all units 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 2.60 agent to the existing Switches for the stack to run properly. - Following a TFTP upgrade on a stack of units it is recommended that a reset is performed to ensure that VLAN information is consistent across the stack. - If you install a SuperStack II Switch 1000BASE-SX/LX Module and connect the Module port to another 1000BASE-SX/LX device, we recommend that both ends of the link are configured to use the same IEEE 802.3z auto-negotiation setting. - The Port Setup 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 Setup 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 differing community strings are configured for units in a stack the result will be to slow down management response (e.g. the CLI will appear to run very slowly). The solution is to ensure all units are configured with matching community strings. - If an existing stack with Spanning Tree enabled is powered-up with a new unit that has Spanning Tree disabled, the setting of the new unit 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 units in this way, the recommended procedure is to either (i) configure the new unit 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 unit where the VLAN was created. In order for ports in other units 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 Command Line Interface through the serial port to reconfigure the IP address for the units =============================================================================== 6: Known Problems With This Release =============================================================================== Version 2.60 is distributed with the following known problems. - If you install a SuperStack II Switch 1000BASE-SX/LX Module into your Switch, ensure that the optical connection to the Module port conforms to IEEE 802.3z. If the signal 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 Setup 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 categorizes 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 unit needs to be power cycled before BOOTP starts 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. =============================================================================== 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: 3300MM (3C16988A) 3300SM (3C16987A) 3300TM (3C16986A) 3300XM (3C16985B) - Chapter 3 (page 72) No. of MAC Addresses supported - Up to 6,000" also applies to the Switches: 3300MM (3C16988A) 3300SM (3C16987A) 3300TM (3C16986A) 3300XM (3C16985B) =============================================================================== 8: Network Management Software Support =============================================================================== The following Network Management software provides support for the Version 2.60 Management Software agent: For Transcend(R) Network Supervisor information and Service Pack downloads, visit: http://www.3com.com/tns Transcend support is available with the following Transcend releases: - Transcend Network Control Services for Windows NT (Version 1.2) - Transcend Enterprise Manager for Windows NT (Version 6.3) used in conjunction with Patch P0256. =============================================================================== 9: Upgrading This Release =============================================================================== The management software can be upgraded by using a TFTP Server or by using the Management Software Upgrade Utility supplied with your Switch. - If you have downloaded the management software designed for a TFTP Server upgrade, place the file s2s02_60.bin in the appropriate directory on the 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 along with the power LED. In this event the software agent should be upgraded via a serial upgrade. - If you have downloaded the management software designed for a serial upgrade using the Management Software Upgrade Utility, place the file s2s02_60.bin in a directory accessible by the PC running the utility. For more information, refer to the Management Guide supplied with your Switch. =============================================================================== 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.
