Table 4-14 Example of load-balancing algorithms #2 (continued) Packet 2 - Destination MAC address: 00-00-00-00-00-01 frame is transmitted out port 2 Last binary bit = 0000 0001 Method 2: SOURCE-BASED ALGORITHM Packet 1 - Source MAC address: 00-00-00-00-00-03 Last binary bit = 0000 0001 frame is transmitted out port 2 Packet 2 - Source MAC address: 00-00-00-00-00-02 Last binary bit = 0000 0000 frame is transmitted out port 1 Method 3: XOR ALGORITHM (best method to use on switch) Packet 1 - Source MAC address: 00-00-00-00-00-03 Last binary bit = 0000 0011 Packet 1 - Destination MAC address: 00-00-00-00-00-01 Last binary bit = 0000 0001 XOR result of binary bits 1 & 1 = 0 frame is transmitted out port 1 Packet 2 - Source MAC address: 00-00-00-00-00-02 Last binary bit = 0000 0010 Packet 2 - Destination MAC address: 00-00-00-00-00-01 Last binary bit = 0000 0001 XOR result of binary bits 0 & 1 = 1 frame is transmitted out port 2 The effects of the destination-based algorithm do not indicate a fault in the network port drivers nor on the switch. Destination-based load balancing is considered a functional FEC/GEC algorithm because packets between switches may not always use the same destination or source addresses. Only single-node-to-switch FEC/GEC uses the same destination address (for example, server team to switch). The algorithm used for load balancing has no effect on fault tolerance; fault tolerance will function the same in any implementation. NOTE: Some switches have the option to change the load-balancing algorithm. In such cases, HP advises using the algorithms in this order of preference: XOR (both), source-based, and destination-based. Switch Vendor Port Trunking Technology Supported by SLB SLB is designed to support most switch vendors' implementation of Port Trunking technology (even if the technology is called by another name). The most important requirement is that SLB only supports Port Trunking technology that has been manually enabled. SLB does not support any kind of Port Trunking auto-configuration protocols (for example, LACP, PAgP). If automatic Port Trunking is required, 802.3ad Dynamic team type should be used with an IEEE 802.3ad Dynamic capable switch. Examples of switch vendor Port Trunking technologies: • Any switch that supports Static 802.3ad (no LACP) • Extreme network's load sharing • HP ProCurve Trunking (or Port Trunking) • HP GbE & GbE2 Port Trunking • Nortel MultiLink Trunking (MLT), but not Split MultiLink Trunking (SMLT) Types of HP Integrity Network Adapter Teams 71

The effects of the destination-based algorithm do not indicate a fault in the network port drivers

nor on the switch. Destination-based load balancing is considered a functional FEC/GEC algorithm

because packets between switches may not always use the same destination or source addresses.

Only single-node-to-switch FEC/GEC uses the same destination address (for example, server

team to switch).

The algorithm used for load balancing has no effect on fault tolerance; fault tolerance will function

the same in any implementation.

NOTE:

Some switches have the option to change the load-balancing algorithm. In such cases,

HP advises using the algorithms in this order of preference: XOR (both), source-based, and

destination-based.
