Chapter 5 Installation CAUTION: Release 4.0.1 embedded software requires a MINIMUM of 16 MB DRAM (Dynamic Random Access Memory) to run on a Cajun P550 Layer 2 supervisor module. BEFORE upgrading, ensure that the switch meets this 16 MB DRAM requirement. A memory upgrade is not required for a Cajun P550 Layer 3 supervisor module, or the Cajun P220. NOTE: Release 4.0.1 introduces a new ASCII configuration file format that replaces the traditional binary (*.
5. Use the CLI setup command to configure the switch. 6. Restore the binary configuration files of the release (3.1 or previous) you want to restore. These configuration files do not reflect any changes you made to the running configuration while using Release 4.0.1. Problem: Release 4.0.1 of the Cajun switch contains new range-checking procedures that may be reasonably more restrictive than those of previous releases. Workaround: If you have a parameter in 3.1 that is outside the 4.
7. Save your Release 3.1 binary configuration file: a. In the Memory Subsystems section of the Web Agent, click TFTP Update. b. In the TFTP Server IP Address field, enter the IP address of the TFTP server to which you will upload the 3.1 binary configuration file. c. In the Filename field, specify the destination path and filename of the configuration file. This is the TFTP server path. d. In the TFTP Target Section pull-down menu, select Save Configuration (binary). e. Click the Update button. f.
Chapter 6 Problems and Workarounds The following problems and workarounds generally apply to all Cajun switches unless expressly specified.
If a port is inadvertently configured to use 3Com tagging, use the following procedure: 1. Reconfigure the port to use either Clear or IEEE 802.1Q tagging. 2. Copy (Save) the Running-Config to the Startup-Config. 3. Reboot the switch. NOTES: • 3Com VLT Tagging is not supported but can be enabled on the Cajun P550 48-port Media Module’s (M5548E-100TC) internal switch ports by using the Web or CLI management interface.
Front Panel Display Problem: The 'lastlink' application on the front panel display does not work on the Cajun P220FE or P220G. Workaround: Currently, no workaround is available. Hardware Frames Transmitted with CRC Errors For the Cajun P550 20-port Module, Model M5520-100TX (P/N 311-0020-000: Revision Level A or B), and the Cajun P550 12-port Module, Model M5512R-100TX, a temperature sensitivity problem has been found when operating at 10Mbps.
Loopback Tests Loopback tests on ports may fail when there is traffic present on the link at start-up. M5520-TX Loopback Tests During Cold Start Occasionally M5520-TX (P/N M5520-100TX) boards with a Quality Phy will fail loopback tests when the board initially is started. The problem corrects itself as the board warms up. M5520-TX Auto-negotiation with Xircom Adapter Cards M5520-TX (P/N M5520-100TX) boards manufactured with a Quality Phy do not autonegotiate with Xircom brand adapter cards.
Intelligent Multicasting Problem: Intelligent Multicasting can block protocols to non-multicast routers. If you have enabled Intelligent Multicasting and configured a VLAN attached to one or more non-multicast routers or multicast-capable endstations, Intelligent Multicasting will configure router ports where multicast-enabled routers reside. These multicast router ports are necessary to allow all multicast packets to the adjacent multicast routers.
OSPF Problem: Upgrading the switch from a Release 3.1 or other previous release to Release 4.0.1 may cause the loss of your virtual link configuration. Workaround: After upgrading and resetting the switch, view your running configuration to ensure that virtual links are intact. (To view your running configuration, click Running Config in the CLI Configuration section of the Web Agent.) If the virtual link configuration is lost, reconfigure the virtual links.
SNMP NOTES: • Cold start traps cannot be transmitted out of inband interfaces when Spanning Tree is enabled. • ipAddrTable does not display inactive interfaces (VLANs). An inactive interface occurs when there are no active ports on a VLAN. • You cannot have more than 10 SNMP community strings per switch. Spanning Tree NOTES: • The Cajun P550 48-port Media Module (M5548E-100TC) supports Spanning Tree for each group of eight ports at the internal switch port.
PPP and Telnet NOTES: • A Telnet session to the serial port via PPP may time out during attempts to transfer large files, such as executable images, to a TFTP server over the same link. However, the file transfer is not terminated. An in-progress TFTP file transfer continues and ends only after the file transfer is completed. • File transfer via TFTP over PPP links may terminate before completion if the dialin PC is used TFTP server.
VLAN Issues NOTE: If the Switch Port attribute Automatic VLAN Creation is set to Enabled, the Allow Learning attribute must also be set to Enabled. Configuring VLANs NOTES: • In certain large configurations, the switch powers up very slowly. • If you set a port’s VLAN trunking mode to Clear, make sure not to change the VLAN Binding Type from the default value: Static.
Chapter 7 Functional Restrictions This section provides information on all of the functional restrictions of the Release 4.0.1 switch software. The functional restrictions are documented alphabetically by functional area (for example, VLANs, DVMRP, IP). Hardware Gigabit Ports Do Not Perform Auto-negotiation Cajun Gigabit Ethernet ports operate at 1 Gbps, full duplex and have been widely tested for interoperability with other devices. Currently, these ports do not support auto-negotiation.
Redundant Controller Support In the event that the redundant switch controller fails, the switch will reset itself. Auto-Negotiation Some network cards do not auto-negotiate correctly with older releases of the 10/100TX modules. This is evidenced by the reception of CRC errors on the mirror port. To avoid this situation, disable auto-negotiation and manually configure the speed and duplex of the mirror port and network card. Spanning Tree IEEE 802.1D Spanning Tree IEEE 802.
For ports that have a 3Com trunking format, the receiving end of the trunked port attempts to interpret the clear BPDUs as trunked packets. Consequently, these BPDUs are discarded at the receiving end. For Spanning Tree to function properly with 3Com trunked ports, the Spanning Tree mode should be set to per-VLAN. In per-VLAN Spanning Tree, there is one instance of Spanning Tree for each VLAN and the BPDUs are tagged with the VLAN ID, ensuring they are interpreted correctly on the receiving end.
Chapter 8 Bug Fixes The following bugs issued in Release 3.1 were fixed in Release 4.0.1. • Switch crashes with a large number of OSPF LSA’s (over 3000) on the L3 Switch. This has only occurred for one very large customer network and can be easily identified by the crash log submitted to technical support. • Secondary IP Addresses on L3 switch do no display the correct index value via SNMP. • You cannot specify a subdirectory when TFTP saving a configuration.
