setting exists. Any features that require configuration for the UUT to function (e.g., required setup before

160
161
162
163
164

Note: EPA received comments from stakeholders that Table 6 lacked details on sub-types of thetechnologies listed in the first column. Stakeholders also suggested that using the max capable link speed
for each technology would provide the most equitable testing condition and allay concern regarding thespecific speeds previously listed. EPA has edited Table 6 accordingly to provide only a precedence of
WAN connection – as now clarified in Steps 8) and 9).

234
235
236
237

The tests outlined in Section 7 require the use of network tester equipment (the test client) capable ofsupporting the protocols used during testing. The test client may consist of several discrete pieces of test
equipment used together to test Ethernet, WAN, and wireless links. This section is intended to provide
guidelines for test client configuration to be applied to the specific pieces of equipment serving the UUT.

238

1) Configure the test client Ethernet ports to be DHCP clients with unique, random MAC addresses.

239
240
241
242
243

2) Configure the WAN port or uplink Ethernet port to assign a random IPv4 address to the UUT. A
static IPv4 address may be set in the UUT if the test client is unable to support random address
assignment. IPv6 may be used if IPv4 support is not present in the test client hardware. If thedevice is configured for DHCP pass-through functionality, the test client shall assign addresses
through the UUT.

2443) Configure the test client to send traffic using UDP.

245
246

4) Configure the test client to provide statistics on data reliability (% of packets received
successfully).

247
248
249

5) Configure the test client to transmit variable length packets or frames using the basic IMIX given
in Table 7 (see Table 3 for references). The packet content shall be random as specified in
Section 5.C).3).

6) Configure the test client to test in a modified aggregation mode. All traffic will pass over a single
link (the uplink or WAN port), and this traffic will be evenly divided between the other connected
Ethernet ports. See Figure 7: Data distribution for multilink tests.

254
2557) If the UUT has wireless capability, the test client shall be capable of functioning as a wirelessclient for the wireless standard(s) specified in Section 6.3.

2568) Configure data connections to the test client as specified in Section 6.5.

265
266
267

A) Tests are performed at two data rates, 1 kb/s (0.5 kb/s in each direction), and the highest rate
supported by the link shown in Table 8. If the link has asymmetric data rate support, choose thehighest rate supported for the direction shown in the table. For data rates higher or lower than thoseshown in the chart, choose the highest data rate according to Equation 1 and adjusting the variable Y
as required to achieve the desired data rate. Note: A link with 100 Mb/s raw throughput will notsupport 100 Mb/s of traffic as specified in this procedure. In this case the traffic rate should be set to50 Mb/s.

4) Accumulate power values for 5 minutes and record the average (arithmetic mean) value observed
during the 5 minute period.

291
292

5) Record the test procedure step and measurements on the test report. If a step is repeated at adifferent link rate, record the additional measurements in the test report.

1) If the UUT only supports WAN connection (IADs only), connect one Ethernet port. Ensure all
Ethernet ports are connected at their highest supported link rate. Measure and record power per
Section 7.1.

301
302

2) Run data at 1 kb/s (0.5 kb/s in each direction) between the WAN and LAN ports. Measure andrecord power per Section 7.1.

303
304

3) Run data at the maximum data rate supported between the WAN and LAN ports. Measure andrecord power per Section 7.1.

305
306
307

C) Wired Network – LAN:
1) Half-Ports Test: Test with half of ports in use, at all supported speeds, as applicable. See Figure
7: Data distribution for multilink tests.

i)

If the UUT has more than two Ethernet ports, connect half of the Ethernet ports (round up to
the nearest whole number of ports). Connect each port sequentially (e.g., a 5-port productwould have ports 1-3 connected and ports 4 and 5 disconnected). Ethernet and other LAN
ports on the UUT must be connected at their highest supported link rate. If a port on the UUT
is specified as the uplink port, it shall be used as the uplink port for testing; otherwise, the firstport shall be used as the uplink port. Measure and record power per Section 7.1.

314
315

ii)

Run data at 1 kb/s (0.5 kb/s in each direction) between the LAN ports. Measure and record
power per Section 7.1.

316
317

iii)

Run data at the rate specified in Section 7.1 between the LAN ports. Measure and record
power per Section 7.1.

318D) Wireless Network - WLAN

3191) Ensure only one Ethernet port is connected to the UUT.

320
321
322
323

2) Establish a single client device in the test client. The WLAN type must be consistent with thepriority specified in Section 6.3 and shall be configured for the highest supported link rate. Record
the supported rate for the network port, the wireless link, and the version of 802.11 being used forthis test. Measure and record power per Section 7.1.

324
325

3) Run data at 1 kb/s (0.5 kb/s in each direction) between the LAN port and the WLAN client.
Measure and record power per Section 7.1.

326
327

4) Run data at maximum data rate supported between the LAN port and the WLAN client. Measure
and record power per Section 7.1.

8 PERFORMANCE EVALUATION

329
330

Performance capabilities shall be evaluated using the tests listed below as applicable to the functions andfeatures of the UUT. UUT configuration shall be as specified in Section 6.

331
332
333

A) Ethernet Throughput - Using a test setup consistent with Section 7.2.C), determine the maximum
data rate supported by the UUT for which there is no packet loss. Record this rate as the measured
maximum throughput.

335
336
337
338

B) Maximum Number of Wireless Clients - Using a test setup consistent with Section 7.2.D), determine
the maximum number of clients supported by the UUT. Clients shall be evenly split between bands if
there is simultaneous dual band support. No data shall be passed other than that required to setup
clients. The data rate shall be set to the maximum rate utilized in Section 7.2.D).4). Record thisnumber as the maximum number of wireless clients.

339C) Maximum Number of NAT Clients

340

1) Record the maximum number of supported NAT clients.

341
342
343
344
345

2) The addition of downstream switches to the test setup and/or combination of tests similar to
Sections 7.2.C) and 7.2.D) may be required to achieve a large number of NAT clients. No data
shall be passed other than that required to configure the clients. The data rate shall be set to the
maximum rate utilized in Section 7.2.B).3) If an additional switch is required, record the number ofwireless NAT and the number of wired NAT clients.
