## Functional Description

The Gigabit Ethernet Adapter targets the increased congestion experienced at the backbone and server in today’s networks, and provides a future upgrade path for high-end workstations that require more bandwidth than Fast Ethernet can provide.

The Broadcom NetXtreme™ Gigabit Ethernet Adapter connects a PCI or PCI-X (5701, 5702, 5703) compliant server or workstation to a Gigabit Ethernet network. This adapter incorporates a technology that transfers data at a maximum rate of one gigabit per second—10 times the rate of Fast Ethernet adapters.

The BCM5700, 5701, 02, 03 base adapters utilize twisted-pair media. At 100 or 1000 Mbps, the adapter uses 4-pair Category 5 cabling and Category 3 when they are running at 10 Mbps.

## Physical Description

The faceplate on the 10/100/1000BASE-T adapter provides an RJ-45 connector for connecting the adapter to another network device.

> Figure 5. Broadcom NetXtreme™ Gigabit Ethernet Adapter Faceplate

The adapter faceplate has four LEDs, one for each port speed option (10 Mbps, 100 Mbps, and 1000 Mbps), and one for Activity. The three port speed LEDs indicate active links, and the ACT LED indicates data transfer status. Once the adapter is installed and the cables are connected properly, the appropriate speed LED is lit and the ACT LED is on if data traffic is present.

Once the adapter hardware has been properly installed on your system, the LEDs indicate the following adapter states:

Table 1. Gigabit Ethernet Port LED Status

LED | State | Description
1000 | On | Good Gigabit Ethernet link.
Off | No 1000 Mbps link; possible link at different speed, possible bad cable, bad connector, or configuration mismatch.
100 | On | Good 100 Mbps Fast Ethernet link.
Off | No 100 Mbps link; possible link at different speed, possible bad cable, bad connector, or configuration mismatch.
10 | On | Good 10 Mbps Fast Ethernet link.
Off | No 10 Mbps link; possible link at different speed, possible bad cable, bad connector, or configuration mismatch.
ACT | Blinking | Brief bursts of data detected on the port.
On | Streams of data detected on the port.
Off | No data detected on the port.

The faceplate on the BCM5701/03S adapters provides two fiber optic connectors for attaching the adapter to a compatible link partner.

> Figure 6. Broadcom 1000-SX Adapter Faceplate

The BCM5701S/03S adapters have four LEDs, one for Link status, and one for Activity (LED1 and LED2 and not used). Once the adapter is installed and the cables are connected properly, the Link LED is lit and the ACT LED will blink if data traffic is present.

Once the adapter hardware has been properly installed on your system, the LEDs indicate the following adapter states:

## Broadcom Advanced Server Program (BASP) Overview

### Introduction

BASP is a Broadcom intermediate software driver for Windows .NET, Windows 2000, Windows NT, NetWare, and Linux, that provides load-balancing, fault-tolerance, and VLAN features. These features are provided by creating teams (virtual adapters) that consist of multiple NIC interfaces. A team can consist of one to eight NIC interfaces and each interface can be designated primary or standby*. All primary interfaces in a team will participate in Load-balancing operations by sending and receiving a portion of the total traffic. Standby interfaces will take over in the event that all primary interfaces have lost their links. VLANs can be added to a team to allow multiple VLANs with different VLAN IDs. A virtual adapter is created for each VLAN added. Load-balancing and fault-tolerance features will work with any third party's NIC adapters. VLANs only work with Broadcom NIC adapters.

| NOTE - *Standby can only be used in Smart Load-Balance mode (see below).

### Limitations

Smart Load-Balance (SLB) is a protocol specific scheme and the level of support for IP, IPX, and other protocols are listed below.

> | Failover/Failback - All Broadcom | Failover/Failback - Multivendor
> | IP | IPX | NetBeui | IP | IPX | NetBeui
> W2K | Y | Y | Y | Y | N | N
> NT 4.0 | Y | Y | Y | Y | N | N
> NW 5.x/6.0 | Y | Y | N/S | Y | N | N/S
> LX 7.2/7.3 | Y | N/S | N/S | Y | N/S | N/S
> | Load Balance - All Broadcom | Load Balance - Multivendor
> | IP | IPX | NetBeui | IP | IPX | NetBeui
> W2K | Y | Y | N | Y | Y | N
> NT 4.0 | Y | Y | N | Y | Y | N
> NW 5.x/6.0 | Y | Y | N/S | Y | Y | N/S
> LX 7.2/7.3 | Y | N/S | N/S | Y | N/S | N/S

> *Third party adapters must be NICE patched or NESL compliant to be fault tolerant and load balance in a multivendor team in Linux and Netware, respectively.

Smart Load-balance (SLB) mode works with all Ethernet switches without configuring the switch ports to any special trunking mode. Only IP traffic will be load-balanced in both inbound and outbound directions. IPX traffic will be load-balanced in outbound direction only. Other protocol packets will be sent and received through one primary NIC only. Fault-tolerance for non-IP traffic is only supported using Broadcom NICs. The Generic Trunking mode requires the Ethernet switch to support some form of port trunking mode (e.g. Cisco's Gigabit EtherChannel or other switch vendor's link aggregation mode). This mode is protocol-independent and all traffic should be load-balanced and fault-tolerant.

| NOTE – Broadcom recommends disabling the spanning tree protocol at the switch when using BASP. This will minimize the downtime due to spanning tree loop determination when failing over.

## Broadcom Advanced Server Program for Novell NetWare

The following options are supported under Novell NetWare. Refer to "NetWare Driver Software," for additional information.

### Failover and Load Balance

- Adapter teaming for failover (heterogeneous support for released 3Com® 10/100 server adapters, Intel® 10/100 server adapters, and Intel® 82559 and 82544 LAN on Motherboards (LOMs)

### NESL Compliance

For optimum fault tolerance and recovery operations, BASP.LAN relies on the NIC drivers to generate NESL (NetWare Event Service Layer) events during link changes and other failure events. NESL is an optional feature in the ODI driver specification and not all drivers support it. For NESL events to propagate properly to BASP.LAN, ODINEB.NLM must be loaded before the NESL compliant ODI drivers.

Do the following to check if a NIC driver supports NESL events. Load BASP.LAN and create a team by binding the NIC adapter to the virtual slot (See instructions and examples below). In the "Virtual Adapter X Team Members" screen of the BASP.LAN's menu interface, the Link status of all bound NIC adapters are shown. Disconnect or connect the NIC adapter's cable and the link status shown on the screen should change immediately if the NIC driver supports NESL events.

### Virtual LAN (VLANs)

- Up to 64 VLANs (63 tagged and 1 untagged) per adapter using IEEE 802.1Q-1988 tagging (64 is the maximum configurable, although 32 is the maximum operable). VLANs only work with Broadcom or Alteon® NIC adapters.

### Offloading

- IP, TCP/UDP checksum – NetWare 5.0 or greater only

### Power Management

- Wake on LAN (magic packet, specific pattern) at 10/100 Mbps only (5701, 5703)

### PCI Hot plug

- Support for Dell PCI Hot plug

## Broadcom Advanced Server Program for Linux

The following options are supported under Linux. Refer to "Linux Driver Software" for additional information.

### Failover and Load Balance

- SLB mode works with all Ethernet switches without configuring the switch ports to any special trunking mode. Only IP traffic will be load-balanced in both inbound and outbound directions.

- Generic trunking mode does not require NICE and can work with any NIC, however, it requires the Ethernet switch to support the technology and be properly configured. This mode is protocol-independent and all traffic should be load-balanced and fault-tolerant.

- 802.3ad mode requires NICE drivers and Ethernet switches supporting IEEE 802.3ad Link Aggregation. This mode is protocol-independent and all traffic should be load-balanced and fault-tolerant. All the physical interfaces in the 802.3ad teams are defaulted to be LACP active. A 802.3ad team requires all the member NICs support NICE. All the member NICs, once in the 802.3ad team, will be set with the same MAC address.

### Virtual LAN (VLAN)

- VLANs can be added to a team to allow multiple VLANs with different VLAN IDs. A virtual device is created for each VLAN added.

### Power Management

- Wake on LAN (magic packet, specific pattern) at 10/100 Mbps only (5701, 5703)

| NOTE – Adapter speed connection when the system is down waiting for a wake up signal is either 10Mbs or 100Mbs, but can return to 1000 when the system is up and running if connected to a 1000 Mbs capable switch. Systems intending to use WOL should be connected to a switch capable of both 1000 and 10 or 100 speeds.
