Cisco vs. D-Link, HP and NETGEAR competitive lab test
Fri, 2/25/11 - 9:24pm    View comments

TollyCiscoCisco recently commissioned the independent test lab, The Tolly Group, to perform a competitive lab test that pitted Cisco's 300 Switches against comparable switch offerings from D-Link, HP and NETGEAR (in all, a total of 11 switches were tested).

As shown in the below chart, Cisco's switches were tested for power efficiency in 10/100 PoE, 10/100 Non-PoE and Gigabit Ethernet against switches from D-Link, HP and NETGEAR:

LAN Switch: Layer 2 Power Consumption (Watts)

Below, Cisco is claiming to be the only vendor in the test to offer both "energy detect" and "power scaling" features:

LAN Switch Energy Conservation Features

In the charts below, Cisco is claiming that its latency was the lowest of all switches tested for all frame sizes:

Gigabit Ethernet LAN Switch: Layer 2 System Latency (usec) Under 100% Load

In the below summary of feature support, Tolly engineers validated a range of features on each of the devices and reviewed each systems' configuration screens to identify the presence or absence of other functions:

LAN Switch Feature Summary

Below, Tolly engineers related throughput to device cost by calculating the cost of each Gbps of throughput:

Ethernet LAN Switch: Price/Performance

The tests below were run to determine how many ports could deliver 15.4W simultaneously:

LAN Switch: Power over Ethernet (PoE) Support

The test compared the below eleven LAN switches that were fully managed and without proprietary stacking ports. While actual port count varied slightly among switches, all had at least 24 ports of either Fast Ethernet (10/100) or Gigabit Ethernet copper ports. Most switches had 2 or more additional Gigabit Ethernet links and/or dual-personality links:

Systems Under Test

As shown below, while NETGEAR latency was competitive, the D-Link switch and the HP E2610 had latency that was some 3x longer than Cisco at larger packet sizes:

Gigabit Ethernet LAN Switch: Layer 2 System Throughput & Latency Under 100% Load
