The adapter has four LEDs, one for each port speed option (10 Mbps, 100 Mbps, and 1 Gbps), and one for Activity. The three port speed LEDs indicate active links, and the Activity LED indicates data transfer status. After the driver is loaded and the cables are connected properly, the appropriate speed LED is lit and the data LED is on if data traffic is present.
Before the port LEDs can provide troubleshooting information, the adapter must be connected to the network (see "Installing the Hardware"), and the network drivers for your particular operating system must be installed.
The adapter has two LEDs, one for each Activity (ACT and LINK). The ACT LED indicates data transfer status. After the adapter is installed and the cables are connected properly, the speed LED is lit and the ACT LED is on if data traffic is present. The LINK LED indicates the port speed option (10 Mbps, 100 Mbps, and 1000 Mbps) for ports 0 and 1.
Before the port LEDs can provide troubleshooting information, the adapter must be connected to the network (see "Installing the Hardware"), and the network drivers for your particular operating system must be installed.

The Length sub tab allows you to verify cable length and determine whether your configuration has the appropriate cable, which are calculated by a Return Loss algorithm. This utility allows you to determine whether the problem is with the adapter or in the cable plant.
Interface components for the BACS2 Cable Analysis/Channel Pairs window are described below:
Distance: This field presents the estimated cable length in meters by averaging all four channels using Return Loss algorithms.
Margin: Margin yields the minimum distance between the measured cable pair and the maximum IEEE 802.3ab limits. The unit is in dB.
Each channel's frequency response appears based on the computation by the cable algorithms. The two graphs represent the values calculated by the Cable Loss and Return Loss algorithms. The vertical axis represents the gain in dB and the horizontal axis represents the operating frequency. The blue graph is the IEEE 802.3ab limit and the red graph is the actual computed values for a particular twisted pair. The minimum Margin and Frequency Margin fields in the Cable Length display are derived from these graphs.

NOTE: Network connection will be lost when running this test. |
The combination of the cable length and the cable status reveal the state of the cable connection between the local adapter and the far end node (hub/switch/routers). The cable status will display possible problems associated with the cable if the cable is not in working order. In this case, displayed cable length is meaningless since the correct cable length cannot be calculated properly with a broken cable. The status window displays various error messages that diagnose possible problems associated with the cable.
The following section describes how to test network connectivity for Windows 2000, Windows Server 2003, NetWare, and Linux.

NOTE: Network connectivity can also be tested using the Network Test feature on the Broadcom Advanced Control Suite 2. |
Use the ping command to determine if network connectivity is working.
Ping an IP host on the network to verify connection has been established:
From the command line, type ping <IP address>, then press Enter.
This will display the packet send/receive status.
To verify that the Ethernet interface is up and running, run 'ifconfig' to check the status of the Ethernet interface. 'netstat -i' can also be used to check the statistics on the Ethernet interface. Consult manual pages for more information on 'ifconfig' and 'netstat'.
Ping an IP host on the network to verify connection has been established:
From the command line, type ping <IP address>, then press Enter.
This will display the packet send/receive status.

The following table lists know problems and solutions using Windows 2000 or Windows Server 2003:
Problem: Able to create Broadcom LAC connections icons having same name under network properties menu. |
Solution: In Windows 2000, each network adapter installed properly will have an icon in Network Properties window. The name of the icon is usually in the form of "Local Area Connection ##" and where ## is a number starting from 1. The names of icon can be changed by right clicking the icon and selecting rename. The name of the icon is only meaningful to the Network Properties window. Sometimes the system administrators will rename these icons to easily differentiate the network connections. When BASP is configured, BASP will create additional adapter icons and rename the icons. The naming convention is to allow end users to quickly identify the adapter with corresponding team and VLAN. The names of the icons created by BASP therefore are not recommended to be changed. |
Problem: Uninstalling the BASP software and user is prompted to reboot early |
Solution: In Windows 2000, after configuring BASP team, the system may sometimes prompt user to reboot. This is because Plug and Play on W2k may fail to commit any change in the network protocol binding. Users can choose not to reboot and continue configuring intermediate driver without having any side effect. When user has finished all the configuration, it is required to reboot. |
Problem: Cannot enable VLAN after it is disabled |
Solution: In Windows 2000, BASP creates additional network connections in "Network Connection and Dail-up" Window. Similar to physical network connections, these virtual connections can be disabled via the context menu. However, if these virtual connections are re-enabled, the system will report error as "connection failed!". This is known problem with Windows 2000. When this happens, reboot the system will enable the virtual connection again. |
Problem: Able to configure Internet Connection Sharing (ICS) when there aren't any unassigned adapters. | Solution: Windows 2000 networking is shipped with the Internet Connection Sharing (ICS), which is designed to allow multiple computers accessing the Internet via a Windows 2000 system. To configure ICS, a user would need to select a network connection as "outside" connection, and another network connection as "inside" connection. Broadcom has observed that ICS allow any available network connection to be "outside" and "inside" connection, regardless of the BASP team configuration. Broadcom recommends that the user not select any network connection that is part of the BASP team to be "outside" and "inside." |
Problem: Team configuration is not retained when user goes back to edit. |
Solution: In configuring BASP team configuration, the actual changes of the configuration is not committed until the user click "OK" in "Network Properties" window. If a user chooses not click OK and instead goes back to the BASP team configuration window, all the previous uncommitted changes will be lost and user will need to reenter the configurations. As a workaround, the user should always click "OK" in "Network Properties" window after making changes. |
Problem: IP address is configurable on a member of the team. |
Solution: When a team is created, the TCP/IP properties for the adapters are unselected. The user can manually select and configure TCP/IP properties of the adapters and configure an IP address. This is a limitation of the Windows 2000 network installation paradigm, where this invalid configuration is still allowed. |
Problem: When creating 64 VLANs, all virtual adapters show disconnected or one of the 64 VLANs show disabled. |
Solution: The maximum VLAN configurations are 63 tagged and one untagged VLAN ID 0. If 64 tagged VLANs are created, they are disconnected. A reboot is required and only 63 tagged VLANs show links, although a 64th is disabled. |

The following table lists known Broadcom Boot Agent problems and solutions:
Problem: Unable to obtain network settings through DHCP using PXE. |
Solution: For proper operation make sure that the STP (spanning tree protocol) is disabled or portfast mode (for Cisco) is enabled on the port to which the PXE client is connected. For instance, set spantree portfast 4/12 enable. |
The following table lists known BASP problems and solutions that apply to all operating systems:
Problem: 802.3ad team member links disconnect and reconnect |
Solution: This is a 3rd party issue. It is seen only when configuring
an 802.3ad team This does not occur with a Cisco Catalyst 6500. |
||
Problem: When members of a team consist of other vender's adapters, the team fails to failover and load balance theIPX traffic |
Solution: IPX failover and load balance is only supported when
all members of the team |
||
Problem: When enabling ASF, the BASP stops functioning. |
Solution: Disable ASF BASP consist of following functions:
The Link Aggregation (Teaming) and the VLAN functions utilize virtual address(s), physical Ethernet address and/or IP address. In order for ASF to function correctly, it needs to know a fixed local address (as specified in the ASF specification). With BASP function enabled, the use of virtualized addresses became incompatible with the address used by the ASF therefore; the ASF function should be disabled when BASP is enabled. The Fail-over (and fail-back) is a system function that monitors multiple NIC ports for any failed ports, and performs traffic re-direction to working ports. If the ASF firmware is installed on the port that fails, the ASF function will not work. |
The following table lists known UnixWare problems and solutions:
Problem: In some instances with a Broadcom LOM, when
you try to add the LAN adapter, multiple devices may show up. |
Solution: Login as root and run "/sbin/resmgr |more" You should see the following:
|
The following table lists known miscellaneous problems and solutions:
Problem: When the bus on the system is operating at PCI mode, Broadcom NetXtreme Gigabit Ethernet will perform at PCI mode if it is added by Hot Plug. |
Solution: When the system is booted up without any adapter, the bus will operate at the lowest mode which is PCI. This problem can be overcome by rebooting the system. |
||
Problem: The Broadcom NetXtreme Gigabit Ethernet adapter may not perform at optimal level when it is added by Hot Plug on some system. |
Solution: This is because the system BIOS in some system does not set the cache line size and the latency timer, after the adapter is added by Hot Plug. This problem can be overcome by rebooting the system. |
||
Problem: The Broadcom NetXtreme Gigabit Ethernet adapter can not be seen on the PCI BUS. |
Solution: This is because some of the older servers are advertising themselves as PCI-X capable systems. This causes the NetXtreme network adapter to operate in PCI-X mode; therefore; not to be seen by the PCI bus. This problem can be overcome by configuring the firmware to operate in forced pci mode. Refer to b57diag for configuration instructions. |
