Connection choices are also important where equally balanced bandwidth is needed, such as in a Virtual
Router Redundancy Protocol (VRRP) application . This scenario is illustrated in the next figure .

Throughput and latency performance data
The following three tables describe the performance capabilities of the 10 Gbps, 1 Gbps, and 100 Mbps line
interface module ports of the HP ProCurve Switch 8200zl, 5400zl, 3500, and 6200yl series .
Over a range of packet sizes from 64 bytes to 1518 bytes, the performance levels achieved are described in
terms of the following metrics:
• Throughput level percentage achieved when performing Layer 2 switching and Layer 3 routing; 100% in all
• Throughput in the form of the number of packets per second when performing Layer 2 switching and Layer 3
• Average per-packet latency in microseconds when performing Layer 2 switching and Layer 3 routing. These
values shown are listed for both First In First Out (FIFO) and Last In First Out (LIFO) processing . The LIFO
values represent the packet transmit time, whereas the FIFO values include the switch decision time and the
packet transmit time .
• Percentage of packets dropped in a full mesh configuration; 0% in all cases
The following measurements were performed by HP ProCurve using test equipment manufactured by Ixia
Communications (www .ixiacom .com) . In these tests, the maximum number of supported ports on the HP
ProCurve Switch 5412zl was used . Proportional performance results at 100% of throughput are achieved on
the HP ProCurve Switch 8200zl, 5406zl, 3500-24, 3500-48, 3500-24-PoE, 3500-48-PoE, 3500yl-24G-PWR,
3500yl-48G-PWR, and 6200yl-24G-mGBIC for the maximum number of ports supported by each of those
models . The 100 Mbps table is not applicable to the HP ProCurve Switch 6200yl-24G-mGBIC, because
only 1 Gigabit and 10 Gigabit ports are supported . The 10 Gbps table is not applicable to the
HP ProCurve 3500-24, 3500-48, 3500-24-PoE, and 3500-48-PoE switches, because only 10/100 and
1 Gigabit ports are supported .
