Broadcom Teaming Services: Broadcom NetXtreme II Network Adapter User Guide Troubleshooting Teaming Problems Teaming Configuration Tips Troubleshooting Guidelines When running a protocol analyzer over a virtual adapter teamed interface, the MAC address shown in the transmitted frames may not be correct. The analyzer does not show the frames as constructed by BASP and shows the MAC address of the team and not the MAC address of the interface transmitting the frame. It is suggested to use the following process to monitor a team: Mirror all uplink ports from the team at the switch. If the team spans two switches, mirror the interlink trunk as well. Sample all mirror ports independently. On the analyzer, use an adapter and driver that does not filter QoS and VLAN information. Teaming Configuration Tips When troubleshooting network connectivity or teaming functionality issues, ensure that the following information is true for your configuration. 1. Although mixed-speed SLB teaming is supported by Dell, it is recommended that all adapters in a team be the same speed (either all Gigabit Ethernet or all Fast Ethernet). For speeds of 10 Gbps, it is highly recommended that all adapters in a team be the same speed. 2. If LiveLink is not enabled, disable Spanning Tree Protocol or enable an STP mode that bypasses the initial phases (for file:///T|/htdocs/NETWORK/BroadCom/71921/NetXtremeII/en/teamsvcs.htm[9/26/2012 3:29:14 PM]
